HOUSING INSTABILITY AMONG HEAD START FAMILIES: THE ROLE OF PARENTING PRACTICES, PARENTAL MENTAL HEALTH, AND CLASSROOM QUALITY ON CHILDREN’S ACADEMIC AND SOCIAL-EMOTIONAL FUNCTIONING By Samanta Boddapati A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of School Psychology- Doctor of Philosophy 2017 ABSTRACT HOUSING INSTABILITY AMONG HEAD START FAMILIES: THE ROLE OF PARENTING PRACTICES, PARENTAL MENTAL HEALTH, AND CLASSROOM QUALITY ON CHILDREN’S ACADEMIC AND SOCIAL-EMOTIONAL FUNCTIONING By Samanta Boddapati National estimates indicate that young children account for a significant proportion of people who are unstably housed (Bassuk, DeCandia, Beach & Berman, 2014). Housing instability refers to a range of conditions that includes frequent residential mobility, living doubled-up, and homelessness (Cunningham, Harwood & Hall, 2010). Emerging research has demonstrated that instability during early childhood may affect long-term functioning, especially for children living in poverty (Fowler, Henry, Schoeny, Taylor & Chavira, 2014; Ziol-Guest & McKenna, 2014). Therefore, a primary goal of this secondary data analysis study is to compare the pre-kindergarten outcomes of children who faced housing instability on important academic and behavioral skills. Beyond the effects of early housing instability on children, aspects of the social context, such as parenting practices and quality of care at preschool, can have a beneficial influence on children’s academic and social-emotional functioning (e.g., Herbers, Cutuli, Supkoff, Heistad, Chan, Hinz, Masten, 2011). However, parental mental health challenges, particularly depression, are higher among caregivers facing housing instability, which in turn can jeopardize parenting practices that have well noted effects on child functioning (Suglia, Durarte & Sandel, 2011). Despite these risks, positive environments beyond housing, such as high quality Head Start classrooms, can serve as protective factors for children facing housing instability (Herbers et al., 2011; Militois, Sesma, and Masten 1999; Pianta, Howes, Bryant, Clifford, Early & Barbarin, 2005). Therefore, another important aim of this study is to better understand the complex relations between parental depression symptomology, parenting practices, classroom quality at Head Start, and children’s functioning, among families who faced housing instability at Head Start entry. Specifically, this study tested differences in a moderated-mediation model that aimed to understand whether classroom quality at Head Start served as a moderator by interacting with parenting in the noted relation between parental depression and child functioning through parenting practices. With the exception of mean level differences in parent engagement (.91 [z = - 2.98]), multiple group structural equation modeling revealed no significant differences between children and families who experienced housing instability during the Head Start years and those who were stably housed. Although evidence that classroom quality mitigated risk was not present, the findings did suggest a differential trend in the relation between classroom quality and children’s social-emotional functioning between groups in the non-multiple group analyses. Overall, the results also suggested the important role of parenting approaches during the pre-kindergarten year for all Head Start children. Findings highlight potential unique differences between unstably housed and stably housed children and future directions in research on the role of housing instability during the pre-school years.

that over 40% of families with children in the United States (U.S.) reported a lack of adequate housing, a rate that has remained at or above 40% since 2005 (Federal Interagency Forum on Family and Child Statistics, 2015). These numbers included children who lived in substandard or crowded housing conditions, as well as children from families with housing costs that exceeded family earnings. During the late 2000s, the national economic recession left a large segment of families in the U.S. unemployed, which exponentially increased the number of families who faced stressors related to economic factors (Burgard, Seefeldt & Zelner, 2012). The national landscape of that recession highlights the interrelatedness of economic vulnerability, housing instability, and poverty in the United States. Housing instability, coupled with risks of poverty, appears to pose unique challenges that extend beyond the effects of poverty alone (Cohen & Wardrip, 2011; Sell et al., 2010). Yet, there is a scarcity of literature focused on understanding early childhood and family functioning within the context of housing instability. Housing instability refers to a broad range of housing conditions experienced by a diverse group of families and children. In the present study, housing instability is defined by a continuum of housing risks that includes families who lack adequate housing (e.g., transitional facilities, living with other families, or living in hotels), as well as those who have experienced two or more residential moves in the prior year (e.g., Cutuli et al., 2013; Suglia, Chambers & Sandel, 2015). This definition of housing instability is consistent with academic and legal conceptualizations in the broader literature, which commonly include families who lack stable, 1 physical housing (e.g., homeless), live doubled up with relatives or acquaintances, or frequently move due to economic hardship (Cunningham et al., 2010). Studies with primarily school-aged children have consistently found that children who face both poverty and housing instability are at a greater disadvantage than their stably housed counterparts (Cutuli et al., 2013; Obradović et al., 2009). Unstable housing can endanger children’s academic and social-emotional development due to disruptions in children’s daily environment, resulting in problems related to school readiness, school transitions, attendance, and mental health, including elevated risk for depression and conduct issues (Cutuli et al., 2013; Edidin, Ganim, Hunter & Karnik, 2012; Rafferty, Shinn & Weiztman, 2004). Despite the risk housing instability poses to children at any age, research suggests that families with young children are most likely to face instability (Desmond & Perkins, 2016). Furthermore, early childhood may be a particularly important developmental period for children who face housing instability. Housing instability during early childhood has been linked to academic and behavioral skills related to school readiness, defined as children’s capacity to function in mainstream school settings (Desmond & Perkins, 2016; Fantuzzo, LeBoeuf, Chen, Rouse & Culhane, 2012; Lewit & Baker, 1995; Ziol-Guest & McKenna, 2014). The prekindergarten year is especially critical because children’s functioning at entry into formal schooling at kindergarten is predictive of long-term academic and social-emotional competence (e.g., Duncan et al., 2007). Therefore, frequent disruptions in housing during the pre-school years may place children at greater risk for decreased academic and social-emotional functioning in comparison to stably housed children. In addition, recent literature has indicated that children who face housing instability early in life, regardless of later housing status, are more likely to experience persistent social-emotional challenges (Fowler et al., 2014; Rumbold et al., 2012). 2 However, few existing studies include between-group comparisons of unstably and stably housed pre-school aged children. The existing body of work on housing instability during early childhood is largely focused on the ways in which housing instability places children at a disadvantage. Studies that examine the role of home and school contexts for children facing housing instability are scarce. An important feature of the home context that is critical to early development is parenting. Research indicates that conditions of housing instability and poverty can negatively influence parenting (Koblinsky, Morgan & Anderson, 1997; Gewirtz, DeGarmo, Plowman, August & Realmuto, 2009). However, specific parenting practices (e.g., parental warmth and engagement within children’s learning) have been noted to have a protective role in the relation between economic risks and children’s outcomes (Herbers et al., 2011; Whittaker, Harden, See, Meisch & Westbrook, 2011). Yet, these relations are still less well understood among populations faced with housing risks (Whittaker et al., 2011). Parental mental health appears to be an important factor in understanding the relation between parenting and children’s early functioning for families who experience poverty (Goodman et al., 2011). Specifically, the Family Stress Theory of Economic Hardship postulates that poverty fosters a context in which mental health challenges are more pronounced, and the effects of parental depression on child functioning are mediated through parenting practices (Conger, Wallace, Yumei, Simons, McLoyd, & Brody, 2002). Studies of families who face housing instability have found high rates of caregiver depression, a significant risk factor for decreased parenting quality (Garg, Burrell, Tripodis, Goodman, Brooks-Gunn & Duggan, 2013; Gonzales et al., 2011). Despite the importance of better understanding mental health risks as they relate to parenting, there continues to be a lack of research that concurrently aims to understand 3 the pathways between housing status, multiple dimensions of parenting, parental depression, and early childhood outcomes. Another important aspect of the broader context of care are schools and early childhood center-based programs, such as Head Start, that target families who face economic stressors. These programs have a longstanding history of promoting school readiness outcomes for families faced with economic hardship, as well as strive to incorporate comprehensive family-based services (Bierman, Torres, Domitrovich, Welsh & Gest, 2009). Although research has found mixed associations between classroom level factors and individual child-outcomes, other studies have demonstrated that classroom-level indicators of quality may partially buffer contextual and family stressors for certain groups of children (Burchinal, Peisner-Feinburg, Pianta & Howes, 2000; McWayne, Hahs-Vaughn, Cheung & Wright, 2012). This suggests that high classroom quality offers the potential for consistent and quality care across settings for families faced with housing instability despite the presence of stressors, but no studies to date have examined these supports with Head Start populations who have experienced housing instability. In summary, there are several gaps in the extant literature on children who face housing instability during early childhood. First, there are few existing studies that attempt to disentangle the effects of housing instability from poverty as a developmental context of risk for pre-school aged children. Second, parenting practices offer a promising focus of research to understand how housing problems can negatively affect children’s developmental outcomes. In particular, parents facing significant housing stressors may be at increased risk for depression, which in turn can affect children’s academic, language, and behavior through parenting practices. Third, there is a gap in the research in examining aspects of the school context as they may relate to and influence family-level stressors. Some evidence suggests that classroom quality within Head 4 Start may buffer risks for certain groups of children. Given the complex indirect relations between parental depression, parenting, and children’s functioning, the role of classroom quality in mitigating risk is currently unclear for children facing housing risks. Specifically, no known studies have considered how these aspects of the social context are related to child outcomes during early childhood for children who face housing instability in comparison to more stably housed children. Lastly, research with families facing housing instability are often limited by small sample sizes or represent families faced with a specific type of housing condition (e.g., families living in transitional facilities) due to difficulty with recruitment and retention of participants. Purpose of Study The primary purpose of this study is to contribute to the literature on the distinct role of housing instability as a developmental context of risk. This study focused on how the social context, mainly parenting practices (parent engagement and parental approaches) and parental depression symptomology, may be mechanisms by which housing instability affects family and child functioning. Notably, this study examined the complex indirect and interactive relations of the social context with development; specifically, the indirect role of parenting practices in the relation between parental depressive symptoms and children’s outcomes (mediation), as well as the interaction between parenting and classroom quality as a moderator in the same relations (moderated-mediation). This study also explored whether these relations between developmental outcomes and parenting and classroom quality are valid among a large national sample of prekindergarten children who attended Head Start and whether they were differentially related for unstably and stably housed children. The results of this study can inform prevention efforts at the 5 child, family, and classroom levels for children facing housing instability and poverty during early childhood. Research Questions 1. Does classroom quality moderate the indirect relation between parent depression and children’s outcomes through parenting practices for the full pre-kindergarten sample? 2. Do children’s pre-kindergarten academic and social-emotional skills differ between children who were unstably and stably housed? 3. Do caregivers’ parenting practices and levels of depressive symptoms differ between parents of children who were unstably and stably housed? 4. Do caregiver levels of depressive symptoms, parenting practices, and classroom quality differentially predict children’s academic and social-emotional functioning for families of children who were unstably and stably housed? 5. Do parenting practices differentially mediate the relation between caregiver depressive symptoms and children’s academic and social-emotional functioning for children who were unstably and stably housed during Head Start? 6. Does classroom quality differentially moderate the relation between parenting practices and children’s academic and social-emotional functioning for children who were unstably and stably housed during Head Start? Theoretical Frameworks This study is based on the integration of two theories: Family Stress Model of Economic Hardship and Risk and Resilience. The Family Stress Model aims to understand the risk pathways by which economic pressures may jeopardize child and family functioning. Although the presence of risk factors, such as housing instability, increases the likelihood of less favorable 6 outcomes, not all individuals facing similar circumstances experience decreased functioning. From a risk and resilience perspective, positive functioning in light of adversity is known as resilience (Luthar, Cicchetti & Becker, 2000; Masten, 2001). Specific factors within the environment or the individual that increase the likelihood of positive functioning in the presence of risk are known as protective factors (Jenson & Fraser, 2006; Masten, 2001). This study will build on research that examines how factors related to Head Start care may serve as protective factors for academic and social-emotional outcomes for children facing housing instability (e.g., Masten, Cutuil, Herbers, Hinz, Obradović & Wenzel, 2014). Resiliency approaches suggest that families, caregivers, and children may thrive in the context of adversity through the presence of protective factors within the environment that are related to positive child and family outcomes. Family Stress Model of Economic Hardship One way that economic challenges in family functioning have been studied is through the Family Stress Model of Economic Hardship (Conger et al., 2002). This theoretical model postulates that economic factors, such as the low level of family income, create conditions that elicit economic stress/pressures (Conger et al., 2002). Using Berkowitz’s (1989) FrustrationAggression Model, the Family Stress Model further theorizes that economic pressure (e.g., inability to meet financial needs) may increase affective problems in caregivers (e.g., depression), which in turn is related to a number of disturbances in family functioning, such as use of inconsistent parenting practices and family conflict, that ultimately affect children’s adjustment (Conger et al., 2002). Research examining how economic pressure is related to parenting practices has suggested that caregivers are more likely to use harsher disciplinary practices, display lower levels of sensitive/responsiveness, or inconsistences in parenting when faced with greater economic pressures (Newland, Crnic, Cox & Mills-Koonce, 2013). Due to the 7 well-established nature of the relationship between poverty and economic pressure from previous investigations of the Family Stress Model of Economic Hardship, this study assumes that factors associated with poverty and housing instability are relevant hardship factors that create economic pressures that can adversely affect parenting practices. Risk and Resilience This study will also draw upon a risk and resilience perspective to highlight the ways in which factors within the home and school contexts (e.g., parenting, classroom quality) can potentially serve as risk and protective factors (Masten, 2001). Risk factors are variables either within the broader environment or inherent to an individual, which increase the likelihood of less favorable outcomes (Jenson & Fraser, 2006; Masten, 2001). As previously noted, protective factors are those that increase the chances of positive outcomes, despite the presence of risk (Masten, 2001). The current study extends previous research that has established poverty and socio-economic variables as significant risk factors to child development by examining the influence of housing instability in conjunction with poverty, in addition to previously established risks associated within these contexts (e.g., parental depression) on children’s outcomes (e.g., Curtis, Coorman, Noonan & Reichman, 2014). The construct of resilience has been defined and studied in multifaceted fashion (Masten, 2001). For example, recent literature has begun to examine the construct of family resilience, defined as adaptation of the family unit despite adverse circumstances. This type of approach emphasizes the cognitive appraisals of stress at the level of the family. In contrast, the current study is concerned with the presence or absence of specific environmental factors that may buffer the cascading negative outcomes associated with economic risk (Patterson, 2002). Masten (2001) described two important considerations to understanding resilience. First, positive 8 functioning is described as resilience only in the presence of an adversity that poses significant risk for non-normative development. Factors associated with equal levels of positive functioning across levels of risk are more accurately termed “promotive” factors (Jenson & Frazer, 2006; Masten, 2001). Therefore, resilient functioning requires a threat or risk to development, such as facing challenges associated with poverty or housing instability, in order for protective factors to mitigate this risk. Second, Masten (2001) highlighted the ambiguity implied by the construct of resilience, as the term is socially constructed to occur within the cultural, societal and historical standards by which resilient outcomes are thought to represent normative development. This suggests that resilient functioning may differ based upon factors within the broader context (e.g., cultural norms). In this study, resilient outcomes will be conceptualized through the consideration of children’s school readiness skills. This conceptualization is consistent with previous research studies that have used social skills and early academic outcomes as indicators of positive functioning (e.g., Supkoff, Puig & Sroufe, 2012; Ziol-Guest & McKenna, 2014). Yet, a limitation of this understanding of resilience is that the study may neglect to consider a broader definition beyond certain outcomes valued by the mainstream Western perspective. 9 CHAPTER 2 LITERATURE REVIEW This section reviews the literature in the areas of housing instability during early childhood, parenting, and classroom quality, with an emphasis on Head Start populations. A rationale for specifically focusing on housing instability during the pre-school years leads into a discussion of the conceptualization of housing instability and the historical context surrounding the current state of housing instability. Next, this review focuses on characteristics of families and children who face housing instability. Specifically, this review emphasizes parent depression and child development during early childhood, as well as ways in which these domains may differ between unstably and stably housed families living in poverty. This review also highlights two key aspects of the early childhood context that can promote children’s development: parenting within the home and classroom quality at Head Start centers. Importance of Housing Instability During Pre-School Years The early childhood years, specifically the years prior to formal school entry, are an important period of development with regard to early academic, social-emotional, and developmental outcomes of children. It is well established that poverty is a developmental context of risk that is associated with a myriad of lasting negative outcomes for children across academic, social-emotional, and health domains (Duncan, Ziol-Guest & Kalil, 2010; Magnuson & Waldfogel, 2005; Shonkoff et al., 2012). Emerging literature has noted that families with younger children are also the most likely group to face housing instability (Desmond & Perkins, 2016). Therefore, recent literature in the area of early childhood has begun to focus on the subgroup of children living in poverty who also face housing instability (e.g., Ziol-Guest & McKenna, 2014). 10 Studies demonstrate that housing instability can negatively affect key academic and social-emotional skills that develop during early childhood, beyond the effects of poverty alone (Fantuzzo et al., 2012; Ziol-Guest & McKenna, 2014). Although housing instability at any age may affect development, longitudinal research has suggested that children are particularly vulnerable to housing instability from birth to five, especially with regard to internalizing and externalizing behaviors (Fowler et al., 2014; Rumbold et al., 2012). Moreover, exposure to housing instability at earlier ages is more likely to be linked to social-emotional functioning into the childhood years (Fowler et al, 2014; Rumbold et al., 2012). These findings in the area of early childhood and housing instability are particularly concerning, as school readiness literature has clearly indicated that a range of skills at kindergarten entry, including academic skills, cognitive functioning, and externalizing behaviors, are predictive of long-term child functioning (Duncan et al., 2007; Pagani et al., 2010; Sabol & Pianta, 2012). Specific to children facing housing instability, Herbers and colleagues (2012) found that although early reading skills in first grade were predictive of oral reading fluency throughout elementary and middle school for all children included in their district-wide study of the Minneapolis Public Schools, this relation was stronger for children who faced housing instability at any point in the six prior years prior. Similarly, Griffith, Arnold, Voegler-Lee and Kupersmidt (2016) recently found that housing instability during pre-school, among other family-level factors, in a sample of Head Start families was predictive of social-emotional functioning in early kindergarten. These results suggest that children who experience housing instability during the pre-kindergarten years may already be at risk of facing greater academic and social-emotional disadvantages at kindergarten entry that can persist over time. These 11 findings highlight the importance of better understanding the pre-kindergarten functioning of pre-school aged children. Housing Instability: Definitions, Prevalence, and Historical Context Research studies of housing instability often consider a broad range of families facing a continuum of unstable housing conditions, such as families who are homeless or lack adequate housing (e.g., transitional facilities, living with other families, or living in hotels), as well as families who have experienced several residential moves (e.g., Cutuli et al., 2013; Suglia et al., 2015). While some studies include families living in a specific housing condition (e.g., families living in shelters), others combine families who face a range of unstable housing conditions into one group (Cunningham et al., 2010; Suglia et al., 2015). Research has demonstrated that two to three (or more) residential moves during the childhood years are negatively related to academic achievement and social-emotional outcomes and may serve as an indicator of past or future homelessness for the family, particularly among low-income families (Cutts et al., 2011; Mantzicopoulous, & Knuston, 2000; Simpson & Fowler, 1994; Ziol-Guest & McKenna, 2014). Federal agencies that govern programs for families facing housing instability also provide further insight into the ways in which housing instability has been conceptualized in practice and research. Cunningham et al. (2010) note that the Stewart B. McKinney Vento Act of 1987 (Public Law 100-77) was the first legislative action to protect the rights of homeless families. The McKinney Vento Act mandates the provision of several programs through the U.S. Department of Housing and Urban Development (HUD), as well as protects the educational rights of children through the Education for Homeless Children and Youth Program enacted through the U.S. Department of Education. Programs associated with both agencies include services for families without fixed housing, such as families living in shelters, children in foster 12 care, and families residing in public spaces. Programs supported by the McKinney Vento Education of Homeless Children and Youth Program further include children and families who live doubled-up with other families due to economic hardship, children from migrant families, and children or families temporarily residing in hotels/motels (Cunningham et al., 2010). In 2012, HUD expanded their definition through changes to the Homeless Emergency Assistance and Rapid Transition to Housing Act (HEARTH), which were amendments to the Moving Ahead for Progress for the 21st Century Act (MAP-21). These changes included the provision of services to individuals who may be at-risk of losing their primary residence and cannot secure new housing due to a lack of resources, as well as families who are unstably housed due to barriers such as unemployment or disability (Zlotnick, 2009). Together, the research literature and federal programs operationalize housing instability in terms of a variety of conditions. Definitions include families who lack an immediate stable residence (e.g., homeless, doubled-up, children in foster care) and those who are at-risk for experiencing a loss of residence (e.g., frequent residential moves). Research that has examined children’s outcomes often refers to both groups using the term homeless and highly mobile or HHM (Cutuli et al., 2013; Obradović et al., 2009). Within this literature, terms such as homelessness, residential instability, housing instability, and housing insecurity are also used synonymously. Prevalence National statistics published by the National Center for Family Homelessness indicated that in 2013, over 2.4 million or 1 in every 30 children experienced homelessness/housing instability as defined by McKinney Vento Homeless Assistance Act (Bassuk et al., 2014). The national report further noted that in 2013, the number of homeless children increased in 31states, 13 which was an 8% national increase from 2012. A study by Ma et al. (2008) found that 29.5% of children from low-income households faced housing instability in a sample of 12,746 families from the National Survey of America’s Families (NSAF). HUD (2014) most recently reported that the number of homeless families with children represents 37% of the current homeless population. In 2009, The National Center for Family Homelessness further reported that of 1.5 million children who experienced homelessness as defined by McKinney Vento Homeless Assistance Act, 42% were under the age of 6. Furthermore, the U.S. Department of Education estimated that over 1.2 million children attending public schools were homeless at some point during the 2013 school year, a number that appears to be growing annually (National Center for Homeless Education, 2013). These striking statistics demonstrate that families with young children make up a large percentage of the current homeless population, with a steadily increasing rate of young children that comprise the unstably housed population at the national level. Historical Context and Trends Several scholars posit that the current state of housing and conditions of poverty are a product of a longstanding history of residential segregation of persons of color in the U.S. (Emerson, Chai & Yancey; Massey, 2001; Massey & Denton, 1993; Fong, 1996). Although a thorough historical analysis is beyond the scope of the study, a consideration of the historical context informs the current state of housing instability and whom it affects. Throughout the early and mid-1900s, discriminatory housing practices, such as redlining and gerrymandering led to impeding persons of color, predominantly black families, from home ownership (Massey & Denton, 1993; Sugrue, 2005). In addition, high rates of unemployment due to discriminatory hiring/work practices, as well as “White flight” mentalities confined families of color to specific 14 inner city neighborhoods (Sugrue, 2005). Massey and Denton (1993) further postulate that this confinement fueled economic conditions (e.g., movement of jobs away from black neighborhoods, lack of affordable housing) that created conditions of poverty within neighborhoods in which high concentrations of persons of color lived. Conditions of poverty perpetuated a greater deterioration of these neighborhoods, often located within urban centers. Overall, research has supported these proposed residential patterns, predominantly through studies consistently finding that families of color are more likely to face poverty, especially within inner city neighborhoods (Fong, 1996; Sugrue, 2005; Massey & Denton, 1993). Furthermore, research suggests that families of color are less likely to face voluntary moves, as well as more likely to move to neighborhoods with similar class compositions (Cohen & Wardrip, 2011). Caregiver and Family Factors Related to Housing Instability Research on factors related to chronic and temporary housing instability for families has found that a number of factors associated with poverty, mental health, physical health, and psychosocial stressors are related to housing instability among caregivers. Although poverty and parental depression are the main focus of this particular study due to the established nature of these factors as they relate to housing instability, health conditions and psychosocial stressors are also briefly reviewed as additional related factors that may affect caregivers facing housing instability to fuel conditions of economic stress. Housing Instability and Poverty As noted earlier, housing instability may be more problematic for families living in poverty because their mobility is often unplanned or involuntary and a result of hardship factors or loss of assets (Ackerman, Kogos, Schoff, Izard, 1999; Clark, 2010; Cohen & Wardrip, 2011; 15 Ziol-Guest & McKenna, 2014). Related to these findings, families who move from low-income or high poverty neighborhoods are often likely to move to similar neighborhoods, suggesting that these moves are rarely the result of securing higher quality of housing or neighborhoods (South & Crowder 1998). These findings suggest that housing instability may be more characteristic of families living in poverty, due to factors out of the immediate control of the family (e.g., loss of housing due to limited resources). Existing research provides insight into the correlated demographic characteristics of families facing housing instability. In a 5-year longitudinal study, Shinn et al. (1998) compared over 400 families that applied for sheltered housing New York. Results indicated that 80% of the families seeking sheltered housing at baseline had their own apartment close to five years later. Subsidized housing was the largest predictor of stability at 5-year follow-up. In addition, other demographic characteristics, including being African American, a younger mother, and recently having a child were predictive of initial application for sheltered housing, but were not related to longer term housing stability five years later. While parental education level was found to predict poverty, it was not predictive of shelter requests. Similarly, across recent studies, caregivers facing housing instability were more likely to identify as part of a racial minority group, as well as report that they were a single parent, had their child at either a younger or older age than their counterparts, received fewer years of education, and/or immigrated from another country (Carrion et al., 2014; Cutts et al., 2011). Mental Health An additional noteworthy finding from Shinn et al. (1998) concerned the mental health conditions of the caregivers. They found that rates of substance use and mental illness were higher after experiences with homelessness, which suggested that mental health conditions were 16 less predictive of entry into sheltered housing, but may have developed as a result of experiences with housing instability. Findings from other studies, however, suggest that pre-existing mental health conditions, such as depression, may serve a precipitating risk factor for housing instability (Corman, Curtis, Nonnan & Reichman, 2016; Curtis et al., 2014). Consistent with Shinn et al. (1998), recent literature has also suggested that rates of depression and other mental health conditions are more prevalent among mothers who have faced housing instability for longer periods of time (Suglia et al., 2011; Zabikiewicz, Patterson & Wright, 2014). For example, Zabikiewicz et al. (2014) found that women who were homeless for two or more years were more likely to experience depression and post-traumatic stress, but that the chances of these disorders were higher among women who were also caregivers to children when compared to those who were not parents/caregivers. Similarly, chances of substance abuse increased among women who were parents. Another recent study found that conditions of housing disarray, defined as crowded, dark, noisy conditions as opposed to deterioration, defined as aesthetics of the living conditions (e.g., holes in walls), were predictive of depression and generalized anxiety among women experiencing housing instability (Suglia et al., 2011). Studies have also continually noted that caregiver depression appears to be most predictive of housing insecurity across both cross-sectional and longitudinal studies (Banyard & Graham-Bermann, 1998; Cutts et al., 2011). Yet, results from earlier research suggested that rates of depression among caregivers facing housing instability were similar to rates among caregivers facing other conditions of poverty (Bassuk, Buckner, Perloff & Bassuk, 1998). Physical Health With regard to health outcomes, research has found a higher incidence of specific health conditions across adults facing housing instability. Conditions such as cardiovascular disease and 17 hypertension are common among individuals facing housing instability (Chong, et al., 2014; Vijayaaghavan et al., 2013). Other conditions that are prevalent among homeless adults, specifically women with children, are sexually transmitted infections, poor nutrition, as well as lowered quality of prenatal care, which appears to be related to low-birth weight or premature birth of children (Richards, Merrill & Baksh, 2011; Vijayaraghavan, Tochterman, Hsu, Johnson, Marcus & Caton, 2012). Additionally, researchers have also found that previous or ongoing sheltered status appears to be related to lack of primary care medical services and higher rates of use of emergency departments among women (Duchon, Weitzman, and Shinn, 1999; Vigayaraghavan et al., 2012). Psychosocial Stressors Experiences with specific psychosocial stressors appear to be more characteristic of families facing housing instability. Rates of domestic violence, intimate partner violence, and exposure to other types of trauma have been reported to be particularly high among families experiencing housing instability (Shinn et al. 1998; Vigayaraghvan et al., 2012). These additional stressors compounded with stressors related to housing instability have been noted to influence caregiver/adult psychological wellbeing, mental health, interpersonal relationships/interactions, and parenting practices across studies that have compared low-income stably housed families with those facing housing instability (Bassuk, Perloff & Dawson, 2001; Ingram, Corning & Schmit, 1996; Metraux & Culhane, 1999). Housing Instability and Child Outcomes Housing instability is a context that can affect children’s outcomes both directly and indirectly through the additional challenges imposed by housing conditions on caregiver and family functioning (Ackerman et al., 1999; Cohen & Wardrip, 2011; Suglia et al., 2011). With 18 the growing awareness of the importance of early academic and social-emotional functioning to long-term child development, the research literature has attempted to better understand the relation between housing instability and specific developmental outcomes of children during early childhood (Fantuzzo, LeBoeuf, Chen, Rouse & Culhane, 2012; Masten et al., 2012; ZiolGuest & McKenna, 2014). Academic Functioning The majority of the existing research on housing instability and children’s development has centered on academic achievement of school-aged children (Cutuli et al., 2013; Obradović et al., 2009). Despite somewhat mixed results regarding the influence of housing instability on academic skills, several studies with large, representative sample sizes have reported lowered levels of reading, math, and cognitive skills that can persist throughout schooling when compared to their stably housed peers from low-income households (Cutuli et al., 2013; Obradović et al., 2009; Yu, North, LaVesser, Osborne & Spitznagel, 2008). Furthermore, studies have noted that unstably housed children experience greater challenges with other aspects of the school experience, even when few differences across achievement have been found (e.g., Rafferty, Shinn & Weiztman, 2004). For example, Raffetry et al. (2004) found that parents of formerly homeless youth reported that their children had a less positive school experience and were more likely to repeat a grade level. More specific to early childhood, research has indicated that children who face housing instability during early childhood may demonstrate below average language and literacy skills (Schmitt, Finders & McClelland, 2015; Ziol-Guest & McKenna, 2014). For example, in a recent study, Ziol-Guest & McKenna (2014) analyzed data from over 2,000 children that participated in the Fragile Families and Child Wellbeing study. Results indicated that three or more moves by 19 the age of 5 predicted lowered receptive vocabulary and phonological awareness skills. However, the effect of housing instability was significant only for children from low-income families. Fantuzzo et al. (2012) further analyzed data on over 10,000 children enrolled in the School District of Philadelphia from birth through third grade. In order to determine the unique contribution of the effects of mobility, researchers controlled for variance explained by several potential confounding factors, including SES, race, and prior achievement. Results indicated that children who experienced both homelessness and more frequent school transitions demonstrated lowered standardized test scores and a higher rate of teacher reported classroom behavior problems. These findings directly suggest that housing instability poses greater risk for academic and behavioral problems across school and early childhood care settings. Social-Emotional Functioning Research in the area of mental health and social-emotional functioning for children faced with housing instability has largely focused on adolescent samples. Research with predominately adolescent homeless/runaway youth samples has indicated that children faced with housing instability, specifically youth who lack immediate physical residence, may be at increased risk for experiencing trauma, substance use, anxiety and depression (see review by Edidin et al., 2012). While researchers speculate that mental health concerns, such as mood and anxiety disorders, may pre-exist in this population at earlier ages due to history of trauma, abuse, or other conflicts, there also appears to be an increase of mental health challenges as a result of exposure to homelessness among adolescent samples (Castro, Gustafson, Ford, Edidin, Smith, Hunter & Karnick, 2014; Kamieniecki, 2001). Although findings of this body of literature are largely 20 focused on a specific group, these results demonstrate the potential influence of housing instability on mental health. There are fewer studies that directly examine the mental health/social-emotional outcomes of children facing housing instability with school-aged and early childhood samples. Some of the existing literature suggests that children facing housing instability may not only be at risk for externalizing, internalizing, and self-regulation challenges, but that the effects of housing instability during specific periods of development may have a lasting influence on behavior and social-emotional functioning (Fowler et al., 2014; McCoy & Raver, 2014; Yu et al., 2008 Ziol-Guest & McKenna, 2014; ). Notably, Fowler et al. (2014) found that housing instability during infancy, early childhood, and adolescence were more predictive of behavior problems in a large sample of children reported to be at high risk for child maltreatment. Preschool-aged children specifically between the ages of 4 and 6 who moved more frequently in the 12 months prior to data collection were more likely to exhibit externalizing behaviors and continued to demonstrate problem behaviors at the three-year follow-up. Moreover, caregiver mental health, particularly maternal depression, is also predictive of children’s development (e.g., Goodman et al., 2011; Koblinsky, Kuvalanka & Randolph, 2006). In a meta-analysis of 193 studies conducted on the effects of maternal depression on child functioning, Goodman et al. (2011) demonstrated that maternal depression was related to broad measures of internalizing and externalizing functioning, as well as to negative emotions in children. Although effect sizes were small, they were slightly larger across studies of families living in poverty. In addition, specific conditions of poverty, such as being from a single-parent home were associated with increases in effect sizes for certain clusters of externalizing behaviors. Results of this study also found that children exposed to maternal depression earlier 21 in life may be at greater risk for developing future internalizing and externalizing challenges. Given the previously noted rates of depression among caregivers who experience housing instability (e.g., Suglia et al., 2011), these results provide further evidence of the importance of considering parental depression and specific conditions of poverty as they relate to child functioning to examine differences across contexts of risk during early childhood. Related Health and Developmental Outcomes Other lines of inquiry that may affect early academic social-emotional functioning among children facing housing instability have indicated decreased health outcomes and higher rates of developmental disabilities among children who face housing instability and poverty more broadly. Generally, research has noted that poverty and housing instability may serve as risk factors for poorer health outcomes, including higher rates of illness (e.g., flu, infections), lead poisoning, lack of nutrition/food insecurity, and respiratory illnesses, particularly asthma (Bashir, 2002; Bratt, 2002; Cutuli, Herbers, Lafavor, Ahumada, Masten & Oberg, 2014; Weinreb, Goldberg, Bassuk, Perloff, 1998). Although developmental delays in several areas are often thought to be characteristic of conditions imposed by poverty in general, recent research suggests that delays in areas such as language and motor skills may be exacerbated for those who also experience housing instability (Carrion et al., 2014; Chiu & DiMarco, 2010). Parenting in the Context of Housing Instability While a significant amount of research has noted the potential risks that housing instability poses to child development, there has been less research examining how parenting, an important determinant of early developmental skills for children, is affected within the context of housing instability. The research on parenting during early childhood for families living in poverty provides partial support for the importance of understanding specific parenting practices 22 in the context of economic risk more broadly. The existing literature on parenting in the context of housing instability provides insight into the ways in which housing instability may create unique challenges to parenting for caregivers with young children. The Family Stress Model provides further explanation for the pathways by which parenting and child development may be affected by economic hardship (Conger et al., 2002; McLoyd, Jayarantne, Ceballo & Borquez, 1994). In this study, parenting practices are defined multi-dimensionally drawing on two areas of parenting research in early childhood: parental approaches and parent engagement. With roots in the parenting styles literature, parental approaches have traditionally been studied as patterns of behaviors on two dimensions: warmth and demandingness. Parenting is viewed as falling on a continuum ranging from warm, responsive behaviors (e.g. affectionate) to harsher approaches (e.g., rigid, verbal threats), as well as a continuum from controlling (e.g., strict, high expectations) to few limits (e.g., few or no boundaries) (Baumrind, 1967; Landry, Smith, Swank, Assel & Vellet, 2001; Petril & Deater-Deckard, 2004). Recent research has expanded how parenting practices are conceptualized to move beyond parenting approaches to recognize how active and responsive parental engagement in learning/development, such as enriching activities and involvement with early academics, relates to early outcomes (Sheridan, Knoche, Kupzyk, Edwards & Marvin, 2011). Both areas of parenting are addressed in the present study to provide a more complete, multi-dimensional understanding of high risk families by examining variation across the types of practices, as discussed further below. Parent Engagement Parent engagement, which is an expansion of the term “parent involvement”, refers to a variety of practices that parents engage in with children to foster development (Sheridan, et al., 23 2011). Although there are many ways to conceptualizing parent engagement, Edwards, Sheridan and Knoche (2008) define parent engagement as interactions that foster warmth, support for autonomy, and involve an active participation in learning. Much of the literature on children facing economic risks has focused on the benefits of parental involvement in learning (e.g., literacy support within the home) and the quality of the interactions during these activities in which parents may develop children’s early learning competencies and readiness for school (McWayne, Fantuzzo, Cohen & Sekino, 2004). Research has linked aspects of the home environment and parental behaviors, including several forms of literacy and enrichment within the home (e.g., indicators of shared book reading, interactive styles of book reading, parents’ own literacy practices, attending community events) to early literacy skills among children facing economic risks (e.g., Bracken & Fishel, 2008; Burgess, Hecht & Lonigan, 2002; Hood, Conlon & Andrews, 2008). In addition, parental involvement within center-based facilities (e.g., Head Start) and parental expectations for educational attainment also have documented relations to school readiness skills (Foster, Lambert, Abbott-Shim, McCartyn & Franze, 2005; McWayne et al., 2004; Suizzo & Stapleton, 2007). Although parent engagement practices appear to be universally beneficial, families facing economic risks are not a homogenous group. Research has demonstrated that there may be potential barriers to accessing important resources for home-based stimulation and involvement in children’s schooling, including access to resources and supports (Desimone, 1999). In addition, research has highlighted the differential use of specific practices that relate to the socioeconomic context (Bradley & Corwyn, 2014; Vandermaas-Peeler, Nelson, Bumpass & Sassine, 2009). For example, Vandermaas-Peeler et al. (2009) found that parents with young children from both middle and low-income homes engaged in similar amounts of guidance while reading 24 and playing with their children, but that the practices of middle-income families included a greater emphasis on literacy. Yet, both groups made attempts to foster interest among their children in literacy activities. Such findings indicate the relevance of understanding the ways in which specific aspects of the economic context may result in different parenting practices, but also how certain practices may be similar across families. Despite the growing attention to context-specific differences in parent engagement practices, there has been little work to understand the ways in which housing instability may affect caregiver engagement independently of poverty. An earlier study by Koblinsky, Morgan, and Anderson (1997) compared the parenting practices of children from low-income families that included 31 homeless and 28 stably housed families with children in Head Start. The results suggested that homeless children lived in less positive physical environments, as measured by the Home Observation for Measurement of Environment (HOME), that included more crowded and disorganized spaces. Results further suggested that children of homeless mothers were less likely to receive cognitive and social stimulation within the home. Similar to low-income families, researchers also speculate that families facing housing instability experience significant barriers, including a lack of transportation, resources, and employment, to forms of school-based parent involvement, such as attendance at school events or assisting in classroom services (Jozefowicz-Simbeni & Isreal, 2006). A recent qualitative examination of the types of literacy practices used by mothers and school-aged children living in a homeless shelter in California found that many of the parents reported barriers to engaging in literacy practices due to a lack of physical space or privacy, but, many were, in fact, engaged in literacy practices. Mothers were both observed and reported to engage in literacy practices through public libraries, churches, and schools (MacGillivray et al., 25 2009). Although school was highlighted as a place for literacy learning, many of the mothers described schools in terms of their evaluative components of school (e.g., homework, testing, grades). Researchers believed that this focus might have reflected the challenges associated with adjustment to the expectations of new schools with each transition. These findings also imply that community-based supports, such as churches and public libraries, function as important sources of literacy exposure and resources for parent engagement for families facing housing instability. In summary, the literature on parent engagement as related to housing instability has demonstrated the importance of better understanding the unique literacy practices of unstably housed families. To date, results of these studies suggest that traditional forms of engagement, such as school-based involvement or home-based literacy practices, may be compromised in the presence of housing stressors. Nevertheless, parents may rely on community-based and other alternative forms of support to engage in practices that promote children’s learning and socialemotional growth (Koblinsky et al., 1997; MacGillivray et al., 2009). Parenting Approaches Approaches to parenting which foster positive child outcomes have been widely studied in the child development literature (Baumrind, 1967; Landry et al., 2001; Riley et al., 2014). Research has indicated that several behavioral dimensions of parenting lead to more favorable cognitive and social-emotional outcomes for children, including a warm, supportive, and responsive caregiving style that is also characterized by boundaries and rules, which is referred to as authoritative parenting (Landry et al., 2001; Mistry, Benner, Biesanz, Clark & Howes, 2010; Petril & Deater-Deckard, 2004; Shaw, Winslow, Owens, Vondra, Cohn & Bell, 1998). 26 Research has indicated variation in the use of specific parenting approaches by context (e.g., Lee, Lee & August, 2011). Some existing literature has noted that the stressors associated with socio-economic risks, such as financial stress, may be linked to lower rates of responsiveness and warmth (Jackson, Brooks-Gunn, Huang & Glassman, 2000; Lee et al., 2011). Current literature has found that the relation between financial stress, parental approaches, and child outcomes is much more complex and that the role of socio-economic risks on parenting behaviors and child outcomes vary with factors specific to the developmental context, such as child’s age, race, and type of SES indicator/risk measured (Bradley & Corwyn, 2014; Dotterer, Iruka, & Pungello, 2012). These contextual nuances underscore the need to better understand parenting approaches among specific developmental age groups that face similar types of risks. There is a scarcity of recent literature, however, on the ways in which parenting approaches may differ among those facing housing instability and socio-economic risks during early childhood. Existing findings have suggested that homeless mothers may provide less academic stimulation, as well as display lower levels of warmth and affection within the home environment in comparison to stably housed, low-income mothers (Koblinsky et al., 1997). Mothers from families who were homeless have also been found to be less responsive and observed to display fewer instances of praise. Moreover, research has also examined the use of physical punishment and firm disciplinary practices in samples of homeless families. Koblinsky et al. (1997) found no differences between homeless and low-income, stably housed mothers in the use of discipline, particularly physical punishment, with half of the sample reporting use of spanking within the previous week. More recent literature has suggested a higher rate of physical punishment and overall risk for child maltreatment among those faced with housing instability (Park, Ostler & 27 Fertig, 2015; Perlman & Fantuzzo, 2013) For instance, a longitudinal secondary data analysis of over 2,000 families found that housing instability was associated with higher rates of physical (e.g., spanking) and psychological (e.g., shouting, swearing) aggression towards children in comparison to other low-income mothers in the sample (Park et al., 2015). Results further suggested a higher likelihood of these behaviors occurring during earlier waves of data collection when children were younger (e.g., 3 or 5 years). Yet, this literature-base has often been critiqued for perpetuation of deficit perspectives of the parenting practices of low-income and homeless families (McWayne, Mattis, Green Wright, Limlingan & Harris, 2016). An alternative way in which parenting differences have been studied has been from a more strengths-based perspective. Recent studies with families of children facing housing instability have focused on the benefits associated with positive, warm interactions among unstably housed families. For example, Gewirtz, DeGarmo, Plowman, August, and Realmuto (2009) videotaped and coded a series of parent-child tasks in a sample of 200 dyads with school-aged children (6 to 12 years) living in supportive housing facilities. In addition to parenting behaviors, self-efficacy beliefs or parental beliefs of competence related to sense of control were also assessed. Results indicated that both parenting behaviors, such as positive and less coercive interactions, and self-efficacy were related to children’s behavioral adjustment. However, parenting practices mediated the relationship between self-efficacy and child behavior, indicating that effect of self-efficacy beliefs on children’s behavioral adjustment may be explained through observed parenting approaches. In a related study, Narayan, Herbers, Plowman, Gewirtz and Masten (2012) evaluated expressed emotion of 39 caregivers with younger children, aged 4 to 7 years, living in emergency shelters. Analysis of coded videotaped speech samples during interactive activities 28 with their children indicated that parental warmth was associated with positive involvement and effective parenting (e.g., problem solving, skill encouragement). Criticisms used by parents were correlated with coercive parenting (less positive involvement, problem solving, skill encouragement). Among parents who spoke for longer periods of time in the speech sample, negative affect was associated with fewer positive parenting behaviors and greater levels of teacher reported externalizing behaviors. This research has also attempted to study if parenting is promotive and/or protective to the development of children faced with residential instability (e.g., Herbers, et al., 2011; Militois et al. 1999; Riley et al., 2014). Although high quality parenting may be promotive or beneficial across all levels of risk, a small evidence-base suggests that parenting practices may differentially affect children facing housing instability, such that parenting may serve as a possible protective factor (e.g., Militois et al., 1999). For example, in a recent study, Herbers et al. (2011) evaluated the role of parenting quality in child academic achievement using a sample of 58 parent-child dyads with children aged 4 to 7 years residing in a shelter. Parenting quality was measured through ratings conducted by both the initial interviewer and a trained observer across a series of questions rated on a five-point scale. Notably, results of the study demonstrated that parenting quality moderated the relation between risk and academic functioning. This indicated that children who were experiencing risk and higher quality of parenting had higher academic functioning in comparison to children experiencing similar risk and lower quality parenting. These findings are consistent with literature that has indicated that parenting approaches that are characterized by sensitive, warm interactions, can be protective for children facing other types of socio-economic risks more broadly (Riley et al., 2014; Whittaker, Harden, 29 See, Meisch & Westbrook, 2011). This suggests that positive parenting practices could have a stronger relation to children’s outcomes for those facing greater risks. To date, studies on approaches to parenting in the context of housing instability have primarily covered three main areas. First, findings have focused on the variability in certain parenting approaches, with findings largely concluding that housing instability may result in lowered levels of warmth and increased use of harsher disciplinary practices (e.g., Koblinsky et al., 1997; Park et al., 2015). Second, strengths-focused studies have demonstrated that warm interactions have positive benefits across both early childhood and school-aged children who face house instability, consistent with previous research that has examined parenting approaches more broadly (Landry et al., 2012; Riley et al., 2014). Lastly, some of this research has further suggested that positive parenting practices can moderate risk (Herbers et al., 2011; Militois et al., 1999). Parental Mental Health as a Mechanism of Group Differences Research in the area of poverty offers some insight into potential explanations for the ways in which housing instability may create a distinctive parenting context. As previously noted, several studies have provided support for the Family Stress Model, which suggests that indicators of economic hardship can influence child outcomes through the quality of parenting (Conger, et al., 2002; McLoyd et al., 1994). From an economic stress perspective, housing instability may serve as an additional risk related to economic hardship among families living in poverty, which in turn may affect parenting practices to a greater extent. Several studies have examined indicators of family stress that are associated with socioeconomic risks and parenting, such as parental depression and relationship strain among adult caregivers (Conger et al., 2002; Newland et al., 2013). In addition, barriers to resources may also 30 place additional demands on parents (Haber & Toro, 2004). The Family Stress Model of Economic Hardship theorizes that economic pressure (e.g., unable to meet financial needs) may increase affective problems in caregivers (e.g., depression), which is associated with a number of disturbances in family functioning, such as parenting practices (Conger et al., 2002). One of the most widely researched indicators of the manifestation of economic pressure has been parental mental health, specifically maternal psychopathology, as it relates to decreased quality of parenting (Garg, Burrell, Tripodis, Goodman, Brooks-Gunn & Duggan, 2013; Gonzales et al., 2011; Newland et al., 2013). These findings may have specific implications for families facing housing instability, as previously noted research suggested a higher rates of caregiver psychopathology, such as depression, among caregivers facing housing instability (Curtis et al., 2016; Curtis et al., 2014; Gerwirtz et al., 2009; Suglia et al., 2011). This body of literature clearly denotes that parental psychopathology may be a critical process that is related to parenting quality within the context of housing instability. The specific conditions of housing instability associated with quality of parental mental health and adverse outcomes are unclear. Although families facing housing instability may be exposed to a number of conditions that might affect parenting quality, extant research provides some evidence that housing conditions may be linked to the quality of parenting (Howard, Cartwright & Barajas, 2009; Koblinsky et al., 1997; Suglia et al., 2011; Lindsey, 1998). Across studies that have examined families residing in shelters and transitional facilities, parents reported that restrictions (e.g., rules of the facilities in which they reside), as well as lack of privacy affect their parenting practices (Lindsey, 1998; Meadows-Oliver, 2003; Thrasher & Mowbray, 1995). Parents faced with these conditions also noted difficulty with adhering to family routines (Mayberry, Shinn, Benton & Wise, 2014). Additionally, chaotic physical 31 conditions, such as crowded, noisy, and disorganized spaces have been suggested to pose barriers to parenting practices (Koblinsky et al., 1997; Suglia et al., 2011). These set of findings demonstrate that factors related to housing instability are salient considerations with regards to parenting practices. Yet, these studies provide limited insight into the processes and pathways that affect parenting practices among unstably housed parents of children during early childhood. Head Start and Housing Instability Another context that children facing poverty and housing instability commonly experience are early childhood centers, such as Head Start. Research has consistently demonstrated that Head Start improves critical academic/cognitive and behavioral indicators of school readiness among children living in poverty (e.g., Bierman et al., 2009). The literature base on long-term effects of Head Start on children’s functioning is somewhat mixed. However, a number of studies have reported gains during the Head Start years in academic and socialemotional domains of functioning (e.g., Lee, Brooks-Gunn, Schnur & Liaw, 1990; Puma et al., 2005). In recent years, research has shown that classroom quality is predictive of short and longer-term outcomes (e.g., Pianta et al., 2005) The reauthorization of the Improving Head Start for School Readiness Act in 2007 included new provisions specific to families facing housing instability. These changes included categorical eligibility for highly mobile children, greater emphasis on identifying and enrolling children facing housing instability, and greater attention to services required in order to address the needs of these families (Head Start for School Readiness, 2007; Institute for Children Poverty and Homelessness, 2011). A 2011 policy report estimated that over 1 million children in the U.S. were enrolled in Head Start and close to 40,000 were classified as homeless, with more likely experiencing frequent mobility (Institute for Children Poverty and Homelessness, 2011). 32 These numbers represented a 50% increase of Head Start enrollment of families facing housing instability from 2008 estimates. Although legislative changes have ensured greater enrollment of families facing housing instability into Head Start, there has been little follow-up research that has specifically examined the ways in which Head Start and quality of center-based care may affect child outcomes for children from families facing housing instability. Short and Long-Term Head Start Outcomes A broad literature base provides evidence for the potential benefits of Head Start for children facing socio-economic risk factors. Despite the variation of programs across the U.S., research has demonstrated positive short-term benefits for child and family functioning. Research has indicated that by the end of Head Start, children show improvements in several areas of functioning, including cognitive skills, such as working memory and attention, as well as in skills related to literacy and numeracy (Bierman et al., 2009; Puma, Bell, Cook, Heid & Lopez, 2005; Welsh, Nix, Blair, Bierman & Nelson, 2010; Zill & Resnick, 2006). In addition, participation in Head Start programming has the potential to improve social-emotional skills, such as prevention of externalizing problems and improvement in prosocial skills (Bierman et al., 2009; Milfort & Greenfield, 2002; Puma et al., 2005). Furthermore, Head Start programs have also been noted to improve health and family outcomes, particularly when programs strive to engage parents through home and school communication, parent training efforts, and interventions (McWayne et al., 2004; Puma et al., 2005; Webster-Stratton, Reid & Hammond, 2001). Despite the demonstrated short-term success and potential for Head Start to improve important school readiness skills among children facing socio-economic risks, research has indicated mixed outcomes with regard to the sustainability of gains made during the Head Start 33 years. Key findings, such as those associated with the High Scope Perry Preschool Study, which demonstrated long-term positive outcomes, including higher rates of graduation, higher earnings, and improved social and emotional wellbeing between children living in poverty who attended preschool and those who did not attend preschool, provided early scientific evidence for the importance of high quality preschool for children living in poverty (e.g., Belfield, Nores, Barnett & Schweinhart, 2006). The long term benefits of Head Start have recently been challenged, however, with findings related to the Head Start Impact Study, a national evaluation conducted by the U.S. Department of Health and Human Services (2005) of Head Start programming, which included a comparison group of waitlist children who did not receive Head Start services. Results of the evaluation indicated small effect sizes in academic, social-emotional, and health domains for children who began the program at age 3 or 4 in academic and health domains during the Head Start year. However, there were few lasting effects through third grade, particularly for children who entered at age 4. There were only small, sustained benefits for children who began Head Start at age 3 in the areas of parenting practices, social-emotional skills, and literacy skills. Improvements maintained through third grade were limited to specific groups of children. For example, children whose parents had symptoms representative of mild depression showed greater gains in literacy and social-emotional outcomes throughout their third grade year. While these gains appear small, researchers have suggested that these findings are consistent with previous longitudinal studies that have examined Head Start and other preschool programs (e.g., Perry/High Scope). These previous studies have also found that the beneficial effects for children who attended pre-school compared to those who received other forms of care, may decrease over time and certain outcomes may not be apparent until school-aged years, 34 adolescence, or adulthood (Currie & Niedell, 2007; Schweinhart & Weikart, 1997). Furthermore, alternative outcomes, such as long-term educational placements and grade promotion have been used in other studies to demonstrate the outcomes associated with Head Start (Barnett & Hustedt, 2005; Ludwig & Phillips, 2008). In addition, the effects of preschool may vary based on child’s abilities at entry and may improve from initial functioning, but children’s improvements also depend upon other contextual factors, such as home environment (Lee et al., 1990). Furthermore, a secondary analysis of Head Start Impact Study data indicated that Head Start involvement increased parent involvement through time spent with children (Gelber & Isen, 2013). All of these findings suggest that while gains are most evident after the initial Head Start year, there appear to be continued gains throughout the course of childhood into adulthood associated with high quality preschool programming. Moreover, these research findings also portray the need to understand the influence of early childhood programming on specific groups of children faced with different risk factors. Classroom Quality Beyond the findings related to the short and long-term gains associated with Head Start, it is difficult to make general claims about the effectiveness of Head Start due to the variation in quality across centers (Raver, Jones, Li-Grining, Mtezger, Champion & Sardin, 2008). Research in recent decades has paid greater attention to environmental factors specific to Head Start centers that are related to positive outcomes. Although program and other classroom factors such as higher spending per child and individual teacher characteristics, may result in better outcomes, global indicators of quality at the classroom level have consistently been found to be predictive of positive child outcomes (Curie & Niedell, 2007; Raver et al., 2008). Classroom quality has been conceptualized as both the physical (structural) and interactive elements (e.g., student- 35 teacher interactions) of the classroom that optimize student success (Pianta et al., 2005). Pianta et al. (2005) further note that interactive elements between students, teacher, and materials are often referred to as process quality of the classroom. With regard to process quality, research has identified several important components that are related to children’s classroom success, including positive teacher-student relationships, positive climate, and instructional quality as evidenced through practices such as support or feedback during learning activities (Hamre & Pianta, 2001; 2005). One of the most extensively used approaches to evaluating process quality is based on the Classroom Assessment and Scoring System (CLASS) framework, which proposes that three aspects of process quality are related to student outcomes: emotional support, classroom organization, and instructional support (La Paro, Pianta, Hamre & Struhlman, 2002). The CLASS framework has been validated across national samples of children from pre-school to fifth grade, as well as draws on a literature base that has demonstrated that each of these broad indicators of quality is related to student success (Hamre, Pianta, Mashburn and Downer, 2007; Hamre et al., 2007). The domain of emotional support includes consideration of the general climate, teacher sensitivity, and level of attentiveness to student perspectives (Hamre et al., 2007). Consideration of classroom organizational elements, such as behavior management and opportunities for learning in different formats, as well as instructional support, which includes the level of feedback provided to students, modeling of language, and development of concepts are additional components of the CLASS framework (Hamre et al., 2007; Pianta et al., 2005). Extant research has found relations between these framework domains and student achievement, student-teacher relationships, classroom behavior, language development, and social skills among samples of preschool-aged children (e.g., Hamre & Pianta, 2005; Mashburn et al., 2008; Pianta et al., 2005). 36 Specific to early childhood centers, research has emphasized the importance of emotional and instructional supports (Burchinal et al., 2006; Mashburn, Hamre, Downer & Pianta, 2006; Mashburn et al., 2008; Hamre & Pianta, 2001; 2005). Recent literature has indicated that emotional and instructional process quality more consistently predict children’s outcomes across studies (Pianta et al., 2005; Mashburn et al., 2008). For instance, using three different measures of classroom quality, Mashburn et al. (2008) found that dimensions of instructional support (e.g., feedback, modeling of language) were predictive of academic and language skills (e.g., vocabulary, oral expression, achievement) and that emotional support was predictive of scores on a teacher reported social skills measure across 671 pre-K classrooms. In addition to the process aspects of classroom quality, structural elements also appear to be related to child outcomes across early childhood settings. La Paro, Thomason, Lower, KinterDuffy & Cassidy (2012) note that the Early Childhood Environment Rating Scale (ECERS-R) has been the most commonly used tool to evaluate structural elements of the classroom that are related to child outcomes. Although there is some overlap with dimensions of process quality, the ECERS-R assesses characteristics of the physical environment such as space, types activities, and interactions of language/reasoning across seven subscales (Harms, Clifford & Cryer, 1998). Research has broadly found that dimensions of the ECERS that capture stimulation within the classroom environment and warm, supportive approaches are predictive of preschool and kindergarten success (Burchinal et al., 2006). More specifically, research suggests associations between ECERS-R scores and children’s language skills, mainly expressive language for children in Head Start (Burchinal, Roberts, Nabors & Bryant, 1996; Love et al., 2003; Mashburn et al., 2008). 37 Quality of care as protective process. To date, no existing studies have examined classroom quality or Head Start in the relation between risk and child outcomes for families facing housing instability. Some researchers have considered the protective role of Head Start involvement on child outcomes for children facing poverty risks and family stressors, but the findings appear to depend upon the risk factors under consideration and demographic characteristics, such as race or gender (Burchinal et al., 2006; Burchinal, Peisner-Feinburg, Bryant & Clifford, 2000; Caughy, DiPietro & Strobino, 1994; Vallotton, Harewood, Ayoub, Pan, Mastergeorge & Brophy-Herb, 2012). The quality of center-based care may be more likely to buffer risks for specific groups (Burchinal et al., 2006; Vallotton et al., 2012). For example, Burchinal et al. (2000) used secondary data analysis with three large-scale studies to examine the potential role of the quality of center-based care. Results of the study indicated that classroom quality served as a promotive factor, such that there were no differences across the examined risk factors in the role of classroom quality on most academic or behavioral outcomes, with the exception of language skills. These results demonstrated that quality of care appeared to have a stronger or protective effect on language skills for children of color who also faced socio-economic risks. In a more recent longitudinal study, Burchinal et al. (2006) further found that the quality of center –based care, along with parenting and children’s language skills, all moderated the relation between cumulative risk and children’s academic skills and behavior problems in a sample of 75 African American children. These results along with similar findings reported earlier by Peisner-Feinburg et al. (2001), suggest that there are likely differential effects of the quality of care for children and families with different background characteristics. Furthermore, 38 such findings also highlight the relevance of more clearly understanding the role of center-based care across other specific conditions of risk, such as housing instability. Parenting and Classroom Quality Few studies have examined indicators of quality across social contexts together. Furthermore, no studies have examined indicators of parenting and early childhood care contexts for children facing housing instability in one model. Several researchers, however, have used person-centered analyses to examine the combinations of quality indicators that lead to the most favorable outcomes (Bulotsky-Shearer, Wen, Faria, Hahs-Vaughn & Korfmacher, 2012; McWayne et al., 2012). Using the 1997 Head Start Family and Child Experiences Survey, Bulotsky-Shearer et al. (2012) demonstrated that a profile of high parental school and home involvement, coupled with high classroom quality scores was associated with the most favorable academic and social-emotional outcomes. McWyane et al. (2012) further used the Head Start Family and Child Family Experiences Survey (2006) and found that children’s patterns of skills remained relatively stable throughout their initial Head Start year, but combinations of several contextual variables, including child, parent, and classroom characteristics influenced changes in children’s academic and social skills. While there was clear evidence that parenting styles, family-level demographic characteristics (e.g., parental education), and family involvement in Head Start were positively associated with change over time, there was less clear support for the role of classroom quality using the ECERS-R, as it did not significantly predict change in children’s outcomes over time. Researchers argued, however, that the greater consideration of process elements of classroom quality, as well as the possible longitudinal effect of classroom quality on child outcomes, may be more appropriate considerations in future studies. Studies examining the role of quality in 39 relation to parenting and classroom practices have demonstrated the beneficial and possible protective role of high levels of both parenting and classroom quality. Although the role of classroom quality is somewhat less clear, recent evidence that includes more sensitive measures of process classroom quality have demonstrated positive child outcomes (Pianta et al., 2005). In summary, the literature on parenting and classroom quality suggests that housing status may interact with aspects of the social context to produce differential outcomes for children during early childhood. Evidence in support of the Family Stress Theory suggests that parental mental health may affect parenting practices, a strong predictor of child functioning (Howard, Cartwright & Barajas, 2009; Suglia et al., 2011). However, the role of additional contexts in which children participate (e.g., Head Start) in the established relationships between parent depression, parenting practices, and child outcomes is understudied for children facing housing instability. Classroom quality has been found as one such factor in the Head Start setting that may mitigate risks for certain groups of children facing greater risks (Burchinal et al., 2000). Yet, it is currently unclear how classroom quality and parenting interact to influence child functioning for children who may experience housing risks. Present Study The present study used secondary data analysis to examine whether housing instability during the Head Start years is related to child functioning during the pre-kindergarten Head Start year. Due to the large body of research evidence demonstrating the importance of prekindergarten skills at formal school entry for kindergarten and childhood functioning, outcomes at the end of the pre-kindergarten year were specifically examined to gain greater insight into the processes that might relate to child functioning at this time point (e.g., Duncan et al., 2007). Furthermore, the study aimed to address gaps in understanding how parenting practices, 40 specifically parental approaches, such as warmth during interactions, endorsement of the use of discipline, and encouragement of independence, as well as parental engagement to promote learning and development, are related to child outcomes in the context of housing instability. Given the likelihood of higher rates of depression-related concerns among caregivers facing housing instability reported by previous research, the present study examined whether parental depression could have a role in the mediational pathway (see Figure 1) that directly affected parenting practices and indirectly related to child outcomes (e.g., Sugila et al., 2011). Yet, children and families interact with and participate in different social contexts, including educational settings, which can buffer the risks at the level of the family. Therefore, the present study also examined if Head Start classroom quality moderated the hypothesized mediational pathway (moderated-mediation) as high quality classroom practices at early childhood centers have been identified as contextual influences that can promote positive child functioning (Pianta, 2005; Riley et al., 2014). Figure 1: Family Stress Model of Economic Hardship Results of this study directly expand upon extant literature in two ways. First, this study adds to literature by including an examination of whether the interactive role of parenting and classroom quality affect children’s functioning during the pre-kindergarten year. Second, the 41 primary relevance of the study was to understand the differential relations in the associations between parental depression, parenting, classroom quality, and children’s outcomes for children who experienced housing instability using structural equational modeling techniques. Research Questions and Hypotheses 1. Does classroom quality moderate the indirect relations between parent depression and children’s outcomes through parenting practices for the full pre-kindergarten sample? I hypothesized that in addition to the latent constructs of parenting practices (engagement and approaches) serving as mediators in the relation between parental depression and children’s functioning, classroom quality will further moderate these indirect pathways among the full prekindergarten sample. It is important to note that the hypothesized moderation would occur between potential mediators (parenting practices) and outcomes (child functioning), signifying a moderated- mediation as the full effect (Baron & Kenny, 1986; Hayes & Preacher, 2004) as depicted in Figure 2. This would signify that the interactive effect is dependent upon the levels of the parenting and classroom quality latent constructs. 42 Figure 2: Hypothesized Moderated-Mediation 2. Do children’s pre-kindergarten academic and social-emotional skills differ between children who were unstably and stably housed? I predicted differences between children who were unstably and those stably housed, such that the unstably housed group would demonstrate lower mean scores in academic skills at prekindergarten assessment. However, I expected these differences to be less pronounced due to the influence of Head Start, as consistent with previous research that has demonstrated that Head Start enrollment is related several areas of academic (e.g., language and literacy) and socialemotional (e.g., social skills and problem behaviors) functioning (Bierman et al., 2009; Puma et al., 2005; Zill & Resnick et al., 2006). 3. Do caregivers’ parenting practices and levels of depressive symptoms differ between parents of children who were unstably and stably housed? Consistent with previous research in the area of parenting and housing instability (e.g., Koblinksy et al., 1997), I expected that that caregivers of children who faced housing instability during Head Start may have endorsed lower mean levels of parental engagement, parental approaches (e.g., warmth), and higher levels of parental depression. 43 4. Do caregiver depressive symptoms, parenting practices, and classroom quality differentially predict children’s academic and social-emotional functioning for families of children who were unstably and stably housed? I expected that parent depression would negatively predict children’s outcomes at Head Start completion across both groups due to the strong association noted in the literature between caregiver depression and children’s functioning (e.g., Goodman et al., 2011). I further hypothesized that parenting practices and classroom quality would positively predict children’s academic and social-emotional outcomes. I hypothesized that the predictive relations would hold across both the unstably housed and stably housed groups and would likely function in a similar fashion across both groups. However, I discuss the potential for the paths between parenting practices and child outcomes to differ in RQ 5 based on the notion of resilience as part of the hypothesized indirect pathways in RQ 5 5. Do parenting practices differentially mediate the relation between caregiver depressive symptoms and children’s academic and social-emotional functioning for children who were unstably and stably housed during Head Start? Based on the Family Stress Theory of Economic Hardship, I predicted the direct and indirect relationships depicted in Figure 1 for both stably housed and unstably housed families in terms of the nature of the meditational relationship between the two groups. I expected a partial meditational path within the full sample and both groups whereby parenting practices mediated the relation between parental depression and child outcomes, which has been a robust finding with regards to the Family Stress Theory. Although I predicted that parenting practices would mediate the relation between parental depression and child outcomes, the resilience/strengths-based literature, which has not typically 44 taken the mental health (e.g., depression) of caregivers into account, has studied parenting practices as a moderator. Thus, although I predicted that the more likely pathway would be the meditational pathway, especially when also accounting for parental depression it was possible that a differential association could emerge. Given that the indirect pathways are a product of two direct pathways, I predicted that if a difference did emerge in the full mediational relation, it would occur between the direct paths from parenting (approaches, engagement) to child outcomes (social-emotional, language and literacy). Although I hypothesized in earlier questions that there may be mean level differences in depression among caregivers who faced housing instability, I did not expect that differences in the associations between depression and parenting for the two groups. Research has demonstrated that poverty and certain specific conditions of poverty may moderate the relationship between depression and parenting (e.g., Goodman et al., 2011), but I did not predict significant differences in this pathway between groups included in the study because both groups will be drawn from a sample of families facing several risk factors associated with poverty. 6. Does classroom quality differentially moderate the relation between parenting practices and children’s academic and social-emotional functioning for children who were unstably and stably housed during Head Start? I predicted that classroom quality will have a differential effect for children facing housing instability. This supports research on resilience that has indicated that environmental factors may interact and be protective for children faced with housing instability (e.g., Militois et al., 1999; Herbers et al., 2011). Although there is not literature on children facing housing instability specifically, this prediction is rooted in research that indicates that classroom quality 45 can have a differential effect for children from specific groups facing higher risk with regards to child and family-level indicators (e.g., Burchinal et al., 2006). Similar to RQ 1, the hypothesized moderation would occur between potential mediators (parenting practices) and outcomes (child functioning), signifying a moderated- mediation as the full effect (Baron & Kenny, 1986; Hayes & Preacher, 2013) as depicted in Figure 2. If a differential relation of classroom quality is present between groups, the influence of parenting practices in the indirect effect of parental depression on child outcomes may be dependent upon both classroom quality and housing status 46 Figure 3: Full Hypothesized Model with Covariates, Error, and Disturbance Terms Covariate paths depicted as dashed lines; * = dummy coded in analyses 47 Table 1: Methods Chart Research Question 1.Does classroom quality moderate the indirect relations between parent depression and children’s outcomes through parenting practices for the full pre-kindergarten sample?

The purpose of F.A.C.E.S. data collection was to gather a wide range of longitudinal quantitative information on child, family, and centerbased characteristics to evaluate the outcomes of Head Start children, as well as inform Head Start and early childcare initiatives more broadly (Malone et al., 2013). For the 2009 sample, data was collected for over 3,000 children attending 60 Head Start programs located across the U.S. To date, there have been four rounds of F.A.C.E.S data collected, beginning in 1997. The present study extracted data from a subset of the 2009 F.A.C.E.S sample consisting of children who were in their pre-kindergarten year. The study closely examined pre-kindergarten differences between children who were unstably and stably housed during Head Start. Table 1 summarizes the corresponding variables and statistical approaches employed for each research question. The most recent round of F.A.C.E.S (2009) is a longitudinal study that spanned three years of data collection (2009-2012) from a range of informants and sources. F.A.C.E.S data collection included direct child assessments, evaluations of child functioning by parents and teachers, observations of classrooms, and interviews with center directors. The F.A.C.E.S study recruited families of three and four-year-old children at the start of their initial Head Start year and additional data were collected on a yearly basis through the end of the child’s kindergarten year. Children in the three-year-old-cohort were assessed in Fall 2009 (baseline), Spring 2010 (end of first Head Start year), Spring 2011 (end of second Head Start year), and Spring 2012 50 (end of kindergarten year). Children in the four-year-old-cohort were evaluated in Fall 2009 (baseline), Spring 2010 (end of Head Start year), and Spring 2011 (end of kindergarten year). The present study was a cross-sectional examination of the pre-kindergarten year, with the majority of data sampled at Head Start completion (Spring 2010 for four-year olds and Spring 2011 for three-year-olds). In addition, housing status of these children throughout Head Start was also used for the present study. Relevant measures of interest are described below. F.A.C.E.S Sampling Procedures F.A.C.E.S data collection consisted of a multistage sampling procedure, during which Head Start programs, centers, classrooms, and children were identified for sampling during each of the stages (Malone at al., 2013). Although a full description of each stage of sampling is detailed in the F.A.C.E.S user manual (see Malone et al., 2013), a summary of these procedures is provided below. Sampling for F.A.C.E.S employed a probability proportional to size (PPS) method across the first three stages of sampling, which was based on the procedures described by Chromy (1979). This procedure includes random sampling of units within randomly selected clusters. The use of PPS helped ensure the least biased probability of inclusion in the study for each program, center, and classroom. Families and children were randomly sampled using a computer algorithm of approximately 36 newly enrolled children within each of the selected centers in the previous stage of sampling. Sampling procedures further included stratification techniques at each stage of sampling in order to ensure representative selection of the final sample. As described in the F.A.C.E.S user manual, both explicit procedures that involved creation of strata based on a set of characteristics (e.g., census region, minority enrollment, urbanicity), as well as implicit procedures that involved pre-specification of specific characteristics (e.g., percentage of children 51 with disabilities, dual language learners, language within the home) prior to sampling were used to decrease bias in sample selection. F.A.C.E.S did not oversample any subgroup of children or classrooms for this particular cohort. The sample of the F.A.C.E.S study resulted in the inclusion of a large sample of children, families, classrooms, and centers. The study included 3,349 children across 486 classrooms located in 60 programs at baseline in Fall of 2009. Approximately 10 children per classroom with parent consent were targeted for inclusion in the study at baseline data collection. Children who left Head Start during the years in which they were eligible for Head Start during the study period were excluded from the original study. The F.A.C.E.S user manual indicates that these children accounted for roughly 10% of sample loss from Fall of 2009 to Spring of 2010 and a 22% overall sample loss from Spring of 2010 to Spring of 2011. Attrition Unweighted estimates of the attrition for the total sample are presented in Table 2 below. Although the estimates below reflect the percentage of complete data across both three and four-year-olds, the focus of the present study is on data from Head Start exit or the prekindergarten year (Spring 2010 for four-year-olds; Spring 2011 for three-year-olds). Table 2: Unweighted Attrition Rates of Full Sample Child Assessments Parent Interview Teacher Data Fall 2009 94% (3,149) 93%(3,119) 97% (3,259) Spring 2010 95%(2,879) 86% (2,601) 96% (2,906) Spring 2011 89% (2,141) 79% (1,916) 81% (1,956) Spring 2012 84% (935) 81%(896) 80%(892) 52 Weighting and Design Effects Sampling weights are used in complex survey designs to account for unequal probability of sampling and clustering that results from the employment of a stratified multistage sampling procedure, as opposed to a simple random sampling procedure (Bell, Onwuegbuzie, Ferron, Jiao, Hibbard & Kromey, 2012; Osborne, 2011). Weighting allows for generalizability of the results to the full population of interest and adjusts for non-responders. Research studies that have compared unweighted and weighted estimates of nationally representative data, including previous rounds of Head Start F.A.C.E.S, have generally demonstrated that weighted analyses tend to provide more accurate estimates of parameters and standard errors (e.g., Hahs-Vaughn, McWayne, Bulotsky-Shearear, Wen and Faria, 2011; Thomas & Heck, 2001). F.A.C.E.S documentation includes over 40 sampling weights to adjust for both the probability of representation within the sample and nonresponse at the desired time point(s). The sampling weight that was applied in the present study was PRAO5WT. This weight is intended for cross-sectional analyses that incorporate data from the pre-kindergarten year, specifically from the parent interview, child assessment, teacher interview, and classroom observation measures. Sample Characteristics Full F.A.C.E.S Sample The full F.A.C.E.S sample is intended to be a representative sample of children who attended Head Start programming between the years of 2009-2012. The full unweighted sample comprised 3,349 children who were enrolled in Head Start during the fall of 2009. Approximately 48.3% (n= 1,619) of the sample were male and 48% (n= 1,609) were female. The average age at the time of enrollment was 46 months (sd= 6.5) or 3.8 years of age. 53 Approximately 38% of children were identified by parents as Hispanic/Latino, 30% as African American, 20% as White, and 5% as Multi-racial, 2% as Asian American and less than 1% as American Indian or Alaskan Native or Other. At the time of Head Start enrollment, approximately 58% (n= 1,945) of the sample lived in poverty and 61% (n= 2,004) reported that they received multiple forms of public assistance. Pre-kindergarten Sample Due to the emphasis on the pre-kindergarten year functioning, the sample was weighted to adjust for non-response and reflect the broader population during the pre-kindergarten year. Weighting adjusted the sample to include those with data present for the pre-kindergarten measures on the majority of indicators of interest. Although weighting excludes a sizeable portion of the initial sample, Table 3 indicates that few significant mean differences at baseline (Head Start entry) emerged between the included and excluded samples on variables used within SEM modeling in the present study that were available at baseline (Fall 2009). Independent samples t-tests indicated that in comparison to those without pre-kindergarten sampling weights, children with pre-kindergarten weights had higher mean parent-rated problem behavior scores, t(3044)= -2.96, p<.005 and lower standardized receptive vocabulary scores, t(29808)= 3.03, p<.005. Yet mean scores indicated only an approximate three point difference on standardized testing of receptive vocabulary.

As indicated in Table 4, the sample was composed of equal numbers of male and female children. Similarly, approximately half of the sample entered Head Start at the age of three and the other half at the age of four. Children’s primary racial identity was reported as follows: 40% Hispanic/Latino, 32% Black/African American, 21% White/Caucasian, 5% Multi-Racial, 2% Asian/Pacific Islander, and less than 1% identifying as other. Approximately 87% (n=1,313) of survey respondents identified as a biological or adoptive mother. Therefore, maternal characteristics were of primary interest in the study. 55 Maternal race followed a similar pattern of representation as child’s race: 38% Hispanic/Latino, 32% Black/African American, 26% White/Caucasian, 2% Asian/Pacific Islander, 2% MultiRacial, and 1% identifying as other. Family-level indicators of economic risk indicated that 63% (n= 962) of the sample reported meeting criteria for federal definitions of poverty status at the time of pre-kindergarten data collection. Furthermore, 45% (n= 708) of the children in the sample were from a single-parent home with the mother as the primary caregiver and 43%(n= 664) were from two-parent homes with both mother and father as caregivers. Respondents reported that approximately 37% (n= 537) of mothers attained less than a high school diploma, 33% (n= 484) earned a diploma, 24% (n= 326) obtained vocational training or some college, and 6% (n= 89) earned a Bachelor’s degree. According to native language information collected only at baseline, 70% (n= 1,035) of the pre-kindergarten sample reported that English was the primary language spoken to the child within the home at the time of Head Start entry. Unstably Housed Sample A primary sample of interest in the present study is families who faced housing instability during Head Start. The primary inclusion criteria for housing instability in the present study was based on the housing status of families at each data collection time point (e.g., Head Start entry, pre-kindergarten year) who were also assigned a pre-kindergarten weight used for data analysis. Consistent with previous conceptualizations of housing instability within the research literature, the present study defined housing instability as either a lack of stable housing or as families who faced frequent moves in a twelve-month period of time. In other words, children with the relevant pre-kindergarten sampling weight who lacked stable housing (e.g., doubled-up, shelters) at any data collection time point before kindergarten entry and/or those who faced at least two moves during the twelve-month period prior to a data collection time 56 point were included in the unstably housed group (Cutts, 2011). Although 25% (n=375) children with a pre-kindergarten sampling weight present experienced housing instability at least once during Head Start, only children for whom housing information was available for a minimum of two data collection time points were included in the creation of the housing status variable in order to most accurately summarize the status of families in the sample as either having experienced instability or stability, resulting in a final sample of 368 children. As detailed in Table 4, approximately 24% (n= 368, weighted n= 84,072) of children in the pre-kindergarten sample were unstably housed at least once during Head Start. Approximately 23% (n= 88) of the unstably housed families reported experiencing housing instability at two or more time points during Head Start. Child characteristics were comparable to the larger pre-kindergarten sample. Also consistent with the larger sample, approximately 90% (n= 328) of survey respondents identified as a biological or adoptive mother. Family level characteristics, including maternal race and economic stressors were also explored among the unstably housed group. Mother’s identified their primary race as follows: 39% Hispanic/Latino, 26% Black/African American, 32% White/Caucasian, 1% Asian/Pacific Islander, 1% MultiRacial, and 1% identifying as another race. Family-level indicators of economic risk indicated that 70% (n= 254) of the unstably housed sample reported meeting criteria for federal definitions of poverty status at the time of pre-kindergarten data collection. Furthermore, 51% (n= 187) of the children in the unstably housed group were from a female led single-parent home and 36%(n= 138) were from two-parent homes. Among the respondents who were unstably housed during Head Start, 41% (n= 143) of mothers attained less than a high school diploma, 36% (n= 126) earned a diploma, 20% (n= 69) obtained vocational training or some college, and 3% (n= 12) earned a Bachelor’s degree. 57 Table 4: Pre-Kindergarten Sample Characteristics with Stable and Unstable Groups Full Pre-Kindergarten Sample % Total Sample 100 % Unweighte dN 1,554 Weighted N 365,547 Survey Respondent Mother 87% 1,313 304,865 Father Grandparent Other 7% 4% 2% 102 56 20 3,074 2,676 1,720 Child’s Gender Male 50% 775 181,890 Female 50% 771 182,022 Mother’s Race White/Caucasian 26% 353 92,838 African American 32% 485 115,558 Hispanic/Latino 38% 640 136,659 Asian Multi-Racial Other Child’s Race White/Caucasian 2% 2% 1% 18 30 12 6,143 8,810 2,417 21% 296 75,639 African American 32% 485 117,020 Hispanic/Latino 40% 668 143,652 Stably Housed % Unstably Housed Unweighted Percent (N) 1179 Weighted Percent (N) 280,097 24% Unweighted Percent(N) 375 Weighted Percent(N) 85,450 86 % 8% 5% 2% 985 230,012 90% 328 74,853 77 47 17 20,423 12,810 4,953 7% 3% <.5 % 25 9 3 5,693 2,528 442 50 % 50 % 588 139,739 49% 187 43,299 583 183,773 51% 188 42,152 24 % 34 % 37 % 2% 3% 1% 249 65,798 32% 104 27,040 389 93,520 26% 96 22,038 477 103,074 39% 163 33,585 13 27 9 4,764 7,975 1,988 2% 1% 1% 5 3 3 1,379 835 429 20 % 34 % 39 % 211 54,725 25% 85 20,914 391 95,109 26% 94 21,911 500 108,477 41% 168 35,175 75 % 58 % Table 4 (cont’d) Asian Multi-Racial Other 2% 5% <1% 19 64 5 5,828 18,149 1,162 2% 5% <1 % 16 44 3 4,916 12,549 728 1% 7% 1% 3 20 3 912 5,601 435 Child’s Cohort Three-Year-Old 50% 739 183,047 566 141,137 50% 173 41,910 Four-Year-Old 50% 815 183,000 50 % 50 % 613 138,960 51% 202 43,540 Poverty Status No 37% 577 135,496 463 110,260 30% 114 25,209 Yes 63% 962 227,000 40 % 60 % 704 167,340 70% 258 59,399 Family Structure Bio/Adoptive Mother and Father 43% 664 155,713 526 125,707 35% 138 30,006 Bio/Adoptive Mother Only 45% 708 165,331 514 120,927 52% 194 4,404 Bio/Adoptive Father Only One Bio Parent/One non-bio Parent Biological Grandparents Other Non-Relative Maternal Education Less than Diploma 2% 5% 1% 4% 32 81 15 54 7,394 184,741 4,302 14,066 45 % 43 % 2% 5% 1% 4% 26 60 12 41 5,573 13,864 3,154 10,872 2% 6% 1% 4% 6 21 3 13 1,821 4,877 1,148 3,194 37% 537 124,080 390 90,130 42% 147 33,951 Diploma 33% 484 111,298 356 82,754 35% 128 28,544 Vocational/Some College 24% 326 7,8913 257 62,833 20% 69 16,080 Bachelor Degree or Higher Home Language at Entry English 6% 89 20,900 36 % 33 % 25 % 7% 76 18,495 3% 13 2,338 70% 1035 254,539 792 196,527 68% 243 58,012 Non-English 30% 511 109,373 71 % 29 % 379 81,944 32% 132 27,438 59 Missing Data Malone et al. (2013) indicated that F.A.C.E.S sampling weights adjust for nonresponse of full instruments and minimize missing data, however that missing data can still be present at the item or survey level. Upon considering sampling weights, missing information on demographic variables of interest (e.g., race, age, gender) ranged from 0-3% on all study variables of interest. Missing data across variables of interest used within modeling ranged from 0 – 6%, with the exception of expressive language scores, for which 20% of the data was not present. However, as described in the F.A.C.E.S User Guide, data for language assessments may be unavailable to a greater extent than other forms of information due to specific routing procedures used to determine the tests that should be given at each wave (Malone et al., 2013). The present study employed a robust maximum likelihood (ML) estimation method, which uses the Full Information Maximum Likelihood (FIML) as the default method to address missing data (Enders & Bandalos, 2001; Kline, 2011). This approach uses all available or observed information to estimate the model, as opposed to deleting or imputing missing values (Enders & Bandalos, 2001). Although no value is substituted, this approach functions similarly to multiple imputation due to the computation of a model based on observed information. However, an assumption of FIML according to Enders (2010) is that data is either missing completely at random (MCAR) or missing at random (MAR). Under the MCAR assumption, data that is missing is not thought to be dependent upon the value of a specific variable. For example, children who scored low on reading tasks were no more likely to be missing on the letter-word identification task than those who scored high. The MAR assumption is less restrictive and assumes that data that is missing may be dependent upon other variables, but that these variables are accounted within the model. For example, lower literacy and 60 language functioning may be dependent upon economic risk indicators, and therefore, the model accounted for these relations. It is important to highlight there is no true method to determine missing data mechanisms, particularly given the complex nature of secondary data analysis of national data. Although weighting partially adjusts for nonresponse and ensures that a given score represents the appropriate number of persons in the population, the most salient theoretically driven relations were accounted for in the model under the assumption that data may be MAR. Variables and Measures Data of relevance to the proposed study included select information from direct child assessments, observations of the classroom, rating scales (parent and teacher), and parent interview. The present study included five latent variables: parental approaches, parent engagement, social-emotional skills, language/literacy, and classroom quality. Indicators for the hypothesized latent variables are described separately below and depicted in Table 5. Table 5: Hypothesized Latent and Observed Variables For Inclusion in Study Construct Parent Approaches Variable Type Latent Parent Engagement Latent Social-Emotional Skills Latent Language & Literacy Latent Classroom Quality Latent 61 Indicators Warmth Authoritative Authoritarian Energy Head Start Involvement Parent-Child Weekly Activities Parent-Child Monthly Out of Home Activities Parent Rated Problem Behaviors Teacher Rated Problem Behaviors Parent Rated Social Skills Teacher Rated Social Skills Woodcock Johnson Letter Word Identification Peabody Picture Vocabulary Test Expressive One Word Picture Vocabulary Test Early Childhood Environmental Rating Scale, Short Form Table 5 (cont’d) Parent/Caregiver Depression Family Economic Risk Index Maternal Race Child’s Gender Child’s Age at Entry Housing Status ObservedContinuous ObservedCategorical ObservedCategorical ObservedDichotomous ObservedContinuous ObservedDichotomous Classroom Assessment Scoring SystemEmotional Support, Instructional Support, and Classroom Organization Subscales ------- Housing Status Housing instability was represented by a dichotomous variable (HINST 0= No, 1= Yes) that was created from two existing variables at multiple time points in the dataset: type of housing (PnM07) and the number of moves experienced the twelve months prior to the data collection time period (PnM08). Consistent with research and legal definitions of housing instability, families that reported two or more moves during the twelve months prior to data collection time points or those that identified as living doubled up or in transitional housing at any time point during Head Start were coded as having faced housing instability. For children who were in the three-year-old cohort, housing status information was extracted from Head Start entry, spring of their first Head Start year, and the pre-kindergarten year. For children who were in the four-year-old cohort, housing status information was extracted from Head Start entry and the pre-kindergarten year. As noted in the description of the unstably housed sample, only children with the relevant pre-kindergarten sampling weight for whom housing information was available for a minimum of two data collection time points were included in the creation of the 62 housing instability variable in order to most appropriately summarize the housing status of families in the sample. Child Functioning Child functioning during the pre-kindergarten year was assessed in terms of children’s academic and social-emotional skills. The proposed study conceptualized academic skills using standardized literacy and language measures. Social-emotional functioning was comprised of parent and teacher-rated social skills and problem behaviors. Pre-literacy and language skills. Although academic functioning comprises a range of skills, research has demonstrated that language and literacy skills are important predictors of future academic achievement (e.g., Foster et al., 2005), and therefore, were used to assess academic functioning of children in the present study. The Letter-Word Identification subtest from the Woodcock Johnson-III Tests of Achievement or The Batería III Woodcock-Munoz for Spanish-speaking bilingual children measures letter-sound correspondence, an early indicator of phonological awareness. In this task, children were asked to identify pictures, letters, and words. Trained data collectors administered this direct child assessment at each data collection time point in the study. The standard score was used in data analyses (M= 100, SD= 15). Notably, F.A.C.E.S. discontinued the test after three incorrect responses, which is inconsistent with standardized directions of the subtest that dictate that test items are discontinued after six incorrect responses. These changes to the standardized directions may have underestimated the literacy skills of some children. The Letter-Word Identification sub-test has been used in previous published work using F.A.C.E.S (1997; 2006) datasets to conceptualize early literacy skills (Bulotsky-Shearer et al., 2012; McWyane et al., 2012). Cronbach’s alpha estimates for the current sample ranged from 63 .85-.93 for the English version and .67-.97 for the Spanish version across all time points (Malone et al., 2013). Developers of the sub-test reported split-half reliability coefficients that ranged between .97 and .99 for English speaking children and .84-.98 for Spanish speaking children (Woodcock, McGrew & Mather 2001; Woodcock, Munoz-Sandoval, McGrew, & Mather, 2007). The sub-test has also been noted to demonstrate high theoretical construct validity (Woodcock, et al., 2001). Two domains, receptive and expressive vocabulary, were used to measure language functioning. Consistent with previous published work using F.A.C.E.S. data (e.g., BulotskyShearer et al., 2012), two widely used reliable and valid instruments, the Peabody Picture Vocabulary Test, 4th Edition (PPVT-4) and Expressive One Word Vocabulary Test (EOWVT-3), were used in the present study to assess language. Data tables from the current sample indicated reliability estimates on the PPVT-4 that ranged from .91 to .97 for the English version (Malone et al., 2013). The test has noted concurrent validity estimates ranging from .70 to .80 with similar measures of language (Dunn & Dunn, 2007). Developers of the test reported split- half reliability estimates of .95 to .93 for children 3 to 5 years of age. Developers of the EOWVT-3, reported split-half estimates for all ages ranged from .96 to .99 and average test retest reliability is reported to be approximately .90 (Brownell, 2000). Cronbach’s alpha estimates for the current sample ranged from .86 to .90 for the EOWVT-3 (Malone et al., 2013). Standard scores from the tests were included in data analyses (M=100, SD= 15). Although bilingual versions of the language tests (Test de Vocabulario de Imagnes Peabody and Expressive One-Word Picture Vocabulary Test, Bilingual Edition) were also administered in select cases, the English norms were used in the present study for two primary reasons. First, scores across the English (e.g., PPVT-4) and bilingual versions (e.g., TVIP) are 64 not interchangeable due to the use of different norming samples (Brassard & Boehm, 2007; Malone et al., 2013). Since all of the children in the sample were administered the PPVT-4, the standard scores derived using the English norms were included in analyses. Second, scores using both sets of norms (English and bilingual) on the EOWVT-3 were reported for select children, resulting in overlapped scores and a lack of clarity on the most appropriate score for each particular child. In order to remain consistent, the standard scores derived from English norms for the EOWVT-3 and PPVT-4 scores were included in the present study. Lastly, the use of the scores from the English versions of the tests is consistent with previous research that has targeted analyses to the broader group of Head Start children (e.g., Choi, Elicker, Christ & Dobbs-Oates, 2016), however it should be noted that use of English scores may underestimate language functioning of some dual-language students within the sample. Social-emotional. Children’s social skills and problem behaviors were assessed to examine social-emotional functioning. Four sets of measures comprised these two domains in the present study. Social-emotional functioning was measured through rating measures that represented parent-reported social skills (PnSSPAL), parent-reported problem behaviors (PnPBERPB), as well as teacher-reported social skills (RnSSRS) and teacher-reported problem behaviors (RnBPROB2). Parent interviews were completed both in-person and via telephone by F.A.C.E.S staff at Head Start centers and teachers were provided rating scales. Social skills and problem behaviors were measured across 21 parent items and 26 teacher items using a combination of items adapted from valid and reliable instruments, including the Social Skills Rating System (SSRS; Gresham & Elliot, 1990), Behavior Problem Index (BPI; Peterson & Zill, 1986), and the Personal Maturity Scale (Alexander, Entwilse & Thompson, 1987). Due to 65 copyrights on select measures (e.g., SSRS), item-level information was not provided in the dataset. F.A.C.E.S included two composite scales produced from these items, social skills and problem behaviors, which were available in the dataset and were used to serve as an overall index of these constructs in the present study. Parent-reported social skills scores also included approaches to learning questions, whereas teacher-reported social skills score did not. All socialemotional measures were used in previous rounds of F.A.C.E.S data collection (Malone et al., 2013; West, Tarullo, Aikens, Sprachman, Ross & Carlson, 2007). Teacher ratings. Teachers rated children on a 3-point Likert scale with items ranging from never (1) to very often (3). Social skills included 12 teacher items related to the child’s cooperative classroom behaviors (e.g., assisting with cleanup, following rules). Items were drawn from the Personal Maturity Scale and SSRS. The Personal Maturity Scale was originally used in the National Survey of Children and later in a large longitudinal study of children in the Baltimore schools (e.g., Alexander et al., 1987). The full scale consists of 13 items, measuring attention, cooperation, compliance, and perceived interest. Earlier studies reported moderate to high reliability (α= .77 and .86) of the items with young children in first and second grade (Alexander et al., 1987; Alexander, Entwisle & Dauber, 1993). Similarly, SSRS test developers reported high reliability (α= .94) for preschool –aged children. Cronbach’s alpha estimates of the combined social skills items for the current F.A.C.E.S sample ranged from .88 to .90 for the full sample (Malone et al., 2013). Teachers rated the frequency of 14 specific problem behaviors that included aggressive behaviors, hyperactivity, and withdrawn behaviors. The items were drawn from the Personal Maturity Scale and BPI. The BPI, based on the Child Behavioral Checklist, was used in two 66 previous national studies, including National Health Interview Survey and the National Longitudinal Study of Youth, and demonstrated moderate to high reliability, with estimates that ranged from .80 and .91 in studies that have used items from these surveys (Brand & Brinich, 1999; Zlotnick, Johnson & Khon, 2006). Reliability estimates for the current F.A.C.E.S sample ranged from .86 to .88 (Malone et al., 2013). Parent ratings. Parents rated their children also on a 3-point Likert scale with items ranging from 1 (not true) to 3 (very true). The 21 parent items were drawn from the similar measures described above for teachers. Parent items included measurement of problem behaviors (e.g., aggression) and ratings of their perceptions of children’s social skills (e.g., ability to make friends). Entwisle and Alexander (1987) demonstrated adequate reliability (α= .87) of items from the Personal Maturity Scale with parents. Test developers of the SSRS reported internal consistency estimates ranging from .73 to .87 for problem behavior subscales from which items were drawn for the present study (Gresham & Elliot, 1990). Lastly, the BPI also demonstrated reliability estimates close to .90 for parents in previous national studies (e.g., Brand & Brinich, 1999). Cronbach’s alpha estimates for the current sample ranged from .72 to .79 for problem behaviors (Malone et al., 2013). Reliability coefficients for the social skills items in the present F.A.C.E.S were slightly lower and ranged from .68 to .72 across the data collection time points (Malone et al, 2013). Parenting Practices Consistent with a comprehensive conceptualization of parenting that includes consideration of both engagement and approaches to parenting, parenting practices were represented by seven available composite scores for parental warmth (PnWarm), authoritative parenting (PnAuthv), authoritarian parenting (PnAuthrn), parental energy (PnEnergy), parent 67 involvement in Head Start (PnPInvHS), home-based parent-child activities (PnPWKAC2), and out of home parent-child activities (PnMoAct). These items were administered as part of the parent interview at the completion of each Head Start year. Parent approaches. Items that comprised the warmth, authoritative, authoritarian, and energy subscales were derived from 13 items from the Child Rearing Practices Report (CPR; Block, 1965). Parents rated the extent to which they believed statements reflected their practices on a scale of 1 (exactly) to 5 (not at all). However, F.A.C.E.S developers did not compute the original subscales of the CPR that were validated as part of the test development, but rather new subscales that grouped similar items of the measure have consistently been used across F.A.C.E.S cohorts (West et al., 2007). Items from the measure have also been used in other national longitudinal studies (e.g., Early Childhood Longitudinal Study -Birth Cohort) and secondary analyses of F.A.C.E.S data (e.g., Bulotsky-Shearer et al.,2012). Previous research has demonstrated construct and content validity of the larger CPR scale items (e.g., Kochasnka, Kuczysnki & Radke-Yarrow, 1989). In the present study, the internal consistency of the 13 items that comprised parental approaches was moderate (α= .70). Each of the F.A.C.E.S derived subscales are described below. All composites were readily available within the F.A.C.E.S dataset. Warmth. The 4 items from the measure that comprised the warmth score reflected use of parent perceptions of their interactions with their child. Example items include “my child and I have warm intimate moments together” and “I make sure my child knows that I appreciate what (he/she) tries to accomplish.” Authoritative. The authoritative parenting score was derived using 3 items that were intended to screen for parenting behaviors that reflected parental beliefs about setting boundaries 68 and encouraging independence. Example items include “I encourage my child to be independent of me” and “I teach my child that misbehavior or breaking the rules will always be punished one way or the other.” Authoritarian. The authoritarian parenting score was derived using 3 items that assessed parental attitudes about physical punishment and setting rules. Example items include “I believe physical punishment to be the best way of disciplining” and “I believe a child should be seen and not heard.” Energy. The energy score was comprised of 3 items that were intended to reflect the parents’ consistency in adherence to rules and consequences for misbehavior. Example items include “Once I decide how to deal with a misbehavior, I follow-through on it” and “there are times, I just don’t have the energy to make my child behave as they should.” Parent engagement. Parental engagement items included involvement in Head Start activities and enrichment activities both within and out of the home. With regards to involvement in Head Start, parents were administered 14 items related to the frequency of their involvement in Head Start during the years their child was enrolled at Head Start (e.g., volunteered in classroom, attended conferences) that comprised one score (PnINVHS). Items were scored as 1 (not yet) to 5 (once a week). Items demonstrated face validity with previous parent engagement research related to activities that foster children’s schooling experiences and skills during early childhood (Fantuzzo, Tighe, & Childs, 2000; McWayne et al., 2004). Similar to published research with a previous cohort of F.A.C.E.S (2006) data, which indicated an adequate internal consistency (α= .80) estimate of parent involvement items, the present study found support for strong internal consistency (α= .87) across parent involvement items (McWayne et al., 2012). 69 Parent/child activities. Parents were administered 14-items that gauged whether they engaged in home enriching parent-child activities within the previous week of the interview, including telling stories, teaching letters-numbers, and playing games. In addition, 11-items that assessed whether parents engaged in out of home parent-child activities on a monthly basis was also administered, which included activities such as, visiting the zoo, library, and community events. These items comprised two scores: one for weekly activities (PnWCK2) and monthly out of home activities (PnMOACT). All items were drawn from use in previous national longitudinal studies (e.g., National Household Education Survey, Early Childhood Longitudinal Study -Birth Cohort), including earlier rounds of F.A.C.E.S data collection (Malone et al., 2013; West et al., 2007). Consistent with previous studies that demonstrated variable internal consistency (α= .60-.66) of enrichment items across studies (Bulotsky-Shearer et al., 2012; Foster et al., 2005), Cronbach’s alpha estimates in the present sample with pre-kindergarten items indicated borderline acceptable estimates for weekly activities (α= .67) and monthly out of home activities items (α= .64). However, these items demonstrated face validity with broader measures of cognitive stimulation within the home environment (e.g., Home Observation for Measurement of the Environment [Bradley & Caldwell, 1984]). Parent Depression The short form of the Center for Epidemiological Studies-Depression Scale (CES-D; Radloff, 1977), a 12 item screener for depression, was administered at each wave to the parent/caregiver who responded to the survey items. The scale is designed to screen for current (state-specific), on-going depression symptomology. Respondents rated their level of symptomology on a 4-point scale during the parent interview. Scores range from 0-36, with a cutoff score of 15 indicating severe depression, 10-14 indicating moderate levels of depression, 70 and 5-9 indicating mild levels of depression. Internal consistency of the measure is reported at roughly .85 and ranged from .86 to .89 in the current sample across the data collection time points (Malone et al., 2013; Radloff, 1977). The full CES-D demonstrates concurrent validity with similar measures, including the Beck Depression Inventory (Radloff, 1977). Classroom Quality Trained observers rated classroom quality across both structural (OnECERSS) and process quality (OnCLSSIS, OnCLSSES, OnCLSSO) indicators at the end of each Head Start year. Structural aspects of classroom quality were measured using 21 items from the Early Childhood Environmental Rating Scale, Short Form (ECERS-R; Harms, et al., 2005). Items represented in the dataset from this measure were most closely aligned with the Teaching and Interactions, as well as Provisions for Learning subscales. A factor analysis study indicated that items of the ECERS-R loaded on one factor, suggesting that that using a smaller sub-set of the items may be as reliable as the full measure (see Perlman, Zellman & Le, 2004). Total ECERS-R scores are comprised of a mean score and range from inadequate (1) to 7 (excellent). Reliability estimates in the F.A.C.E.S sample ranged from .85 to .87 for the ECERS-R (Malone et al., 2013). The short form also demonstrated high inter-rater reliability, with estimates ranging from .83 to .93 for the present sample. Process quality indicators from the Classroom Assessment Scoring System (CLASS; Pianta et al., 2008) were also available in the dataset. Scores for the three broad domains that comprised the eleven subscales, Emotional Support, Instructional Support, and Classroom Organization were used to represent the process quality components of classroom quality. Trained observers rated classrooms on each of the subscales that measure student-teacher interactions and aspects of the classroom that promote student learning, assigning a mean score 71 from 1 (minimally characteristic) to 7 (highly characteristic) for each of the domains rated. The C.L.A.S.S is a widely used tool in research and has been included in several large-scale, nationally representative studies (e.g., Hamre et al., 2007; La Paro, Pianta & Stuhlman, 2004). A large validation study confirmed the theorized three-factor structure (Hamre et al., 2007). La Paro et al. (2004) reported moderate associations of the C.L.A.S.S subscales with the ECERS-R total score (r= .52 and .40). Cronbach’s alpha estimates for the F.A.C.E.S sample ranged from .82 to .90 (Malone et al., 2013). Malone et al. (2013) further reported that inter-rater reliability estimates demonstrated high correspondence between raters, with estimates ranging from .81 to .86 across subscales. Covariates Four covariates of theoretical relevance to constructs in the model were selected for inclusion in the study as control variables. Each is described below. Family economic risk. The family economic risk (PnECRISK) risk variable is a F.A.C.E.S derived index score that was created by the developers using three economic risk variables: family-level poverty status (PnPovtry), maternal education (PR1MOMED), and family structure (PnFMSTRC). The family economic risk variable represents the number of risk factors faced by the family at each time point, with a max score of three. A score was assigned based on the number of risks that included meeting criteria for poverty status, a maternal education below a high school diploma, and being from a single-parent home. The economic risk score included in the present study was dummy coded for inclusion in the model. Age. The child’s age (P1RCAGE) in months at Head Start entry was included to control for differential years of exposure to Head Start across the three and four-year-old cohorts by the time they reached the pre-kindergarten year. 72 Maternal race. Maternal race (MRACE) was selected for inclusion due to the large percentage of respondents identifying as the child’s mother (~90%). Due to the low frequency of certain groups, the MRACE variable was re-coded to represent a collapsed variable that included identification as White, Black/African American, Latino/Hispanic, or within a category termed “other” to represent the additional sample. Maternal race was dummy coded for inclusion in the model. Child’s gender. Child’s gender (CHGENDER) was represented by binary variable that identified the gender of the child as male or female. Analytic Plan Table 1 depicts the analyses with their corresponding research questions. Analyses were conducted using the Statistical Package for the Social Sciences (SPSS Version 23) with the Complex Samples Module and Mplus Version 7.31 (Muthén & Muthén, 2015). Both packages were selected for their ability to handle complex sampling designs. The primary research questions were answered through Structural Equation Modeling (SEM) and Multi-Group SEM in Mplus Version 7.31. However, several steps were conducted to execute these analyses that included: data cleaning/preparation, preliminary analyses, Confirmatory Factor Analysis (CFA), testing the full conceptual model through SEM with latent variables, subpopulation analyses, and Multi-Group SEM. Data Preparation and Cleaning Initial stages of data analysis consisted of data preparation and cleaning. The raw format of the data consists of child and family data by year (e.g., Fall, 2009, Spring, 2010) and is not separated by cohort. Although all children in the study entered Head Start in Fall of 2009, approximately half the sample was three years of age at Head Start entry and the other half was 73 four years of age, resulting in two potential pre-kindergarten years, Spring 2010 for the fouryear-old cohort and Spring 2011 for the three-year-old cohort. As consistent with recommendations from the F.A.C.E.S user manual, pre-kindergarten variables were created using the PKYEAR grouping variable to guide selection as to the appropriate wave from which to draw data for each child in the study. All pre-kindergarten variables were created using the syntax feature of SPSS Version 23. Preliminary Analyses Preliminary analyses, including descriptive statistics, correlations, and t-tests were conducted on observed variables prior to considering the full model. These analyses were conducted with and without sampling weights. Preliminary analyses served two purposes in the current study. First, descriptive statistics and correlations of the predictor and outcome variables provided greater insight into the sample and relations between the study variables to rule-out issues that may hinder statistical analyses (e.g., multicollinearity). In addition, preliminary group difference testing without latent variables, such as t-tests between stably housed and unstably housed groups on parenting practices, caregiver depression, pre-academic (language and literacy) scores, and social-emotional skills provided a baseline from which to understand potential sources of difference between groups. However, differences using the full latent variable model were of primary interest. Confirmatory Factor Analysis CFA was used to test the latent factor structure of the model (Figure 3). Several observed variables or indicators, further described in the variables and measures section, were hypothesized to load on each construct based on theoretical and practical considerations. For example, scores on a receptive language test, expressive language test, and a letter-word 74 identification task were selected to load together on a construct that comprised language and preliteracy skills. CFA was conducted in a two-step fashion as proposed by the broader literature (Brown, 2015; Anderson & Gerbing, 1988). These steps included initially testing the factor structure of each construct separately, followed by testing the entire measurement model that included all relevant latent constructs and their indicators. Additionally, the latent constructs were first tested on the full sample, followed by the sub-populations of interest (unstably housed and stably housed) prior to the multi-group analyses. Five latent variables were used in the study: parenting approaches, parent engagement, classroom quality, language and literacy, and socialemotional skills. Structural Equation Modeling with Full Sample The next step consisted of testing the overall structural model (Figures 2 and 3) with the full sample (RQ 1). All hypothesized paths of interest, including the moderated-mediation, were specified in the full model. A latent variable SEM approach was selected in the proposed study to parsimoniously and simultaneously test a number of observed variables as latent constructs through the specification of both direct and indirect paths. The hypothesized base model was respecified using modification indices and theory as detailed further in the results section. Although several scholars discuss the relevance of resampling procedures (bootstrapping) in testing mediation, this approach is not compatible in complex survey designs due to the lack of independence across observations (Preacher & Hayes, 2004; Muthén & Muthén, 2015). Therefore, the present study included the default settings in Mplus to test mediation via the MODEL INDIRECT command for the base model and an identical procedure that computes new parameters using MODEL CONSTRAINT for the moderated-mediation. The default approach to testing mediation in Mplus is the delta method, a method that estimates if the standard error 75 distribution of the product of the two direct effects (SEβa·SEβb) that comprise the mediation are significantly different from zero (Bollen & Stine, 1990). Similar to other related tests of mediation (e.g., Sobel test), this approach assumes that distributions are normally distributed and may produce more biased estimates of the standard error when sample sizes are small. Several scholars have demonstrated that testing mediational effects with sufficiently large samples (N > 150) produces similar estimates across both the delta and bootstrapped methods (Bollen & Stine, 1990; Tofighi & MacKinnon, 2016). Recent literature has described a two-step process for estimating moderation models with latent variables interactions (Maslowsky, Jager & Hemken, 2014; Muthén & Asparouhov, 2015). Maslowsky et al. (2014) indicated that a model without the latent variable interaction is first fitted and adjusted, particularly due to the underdeveloped methods for evaluating model fit with latent variable interactions. In Mplus, latent variable interaction models require alternate commands (e.g, Type = RANDOM) that produce limited fit statistics. Since it is assumed that latent variable interactions add no additional variance, means, or covariance that are not already included in the base model, overall fit is expected to be comparable to the base model (Muthén & Asparouhov, 2015). The model without the interaction serves as the base model to which the latent variable model is compared using a more limited set of indices that emphasize parsimony (e.g., Alkaline Information Criterion). In the present study, the moderation paths of interest, the differential influence of classroom quality on the hypothesized mediational paths, caregiver depression on children outcomes through parenting, were computed by creating latent variable interaction terms as outlined by Hayes and Preacher (2013) in their discussion of conditional process analysis. Specifically, these terms were computed between classroom quality and 76 parenting (parent engagement · classroom quality and parent approaches · classroom quality) using the XWITH command in Mplus. The present study used several absolute and relative SEM model fit statistics. As per recommendations found within the literature, decisions of model fit were based on the Root Mean Square Error of Approximation, Comparative Fit Index, Standardized Root Mean Square Residual and Chi-Square Test (Kline, 2011). Consistent with Kline (2011), these fit indices, with cut-off criteria stated below, were used to make decisions regarding model fit. It was expected, however, that the Chi-Square Test would be significant and not an appropriate index due to the large weighted sample size, and thus, the other indices were weighted more heavily in determining overall model fit (Kline, 2011; Hu & Bentler, 1999). The Alkaline Information Criterion was further used for model comparisons. Chi-Square ( χ 2 ). The chi-square statistic tests model fit or misfit with the overall data. A non-significant chi-square value indicates better fit, however, this statistic often performs poorly with large samples and tends to accept the null model, despite true differences (Kline, 2011; Hu & Bentler, 1999). Comparative Fit Index (CFI): This relative fit statistic is an indication of how much the model differs from the null hypothesis (H0) or no relations between elements of the model. Typically, values that range between .9 and 1.0 suggest better fit, with .95 and above often preferred (Hu & Bentler, 1999). Root Mean Square Error of Approximation (RMSEA): This statistic is referred to as an overall (absolute) index of model fit that estimates the variance explained by the model. Lower values of approximately .06 or below suggest better fitting models (Hu & Bentler, 1999). 77 Standardized Root Mean Square Residual (SRMR): The SRMR is a standardized pooled estimation of the square root of the differences in residuals within the covariance matrix. Values between 0 and .08 are considered appropriate, but a value of less than .05 is preferred (Hu & Bentler, 1999; Kline, 2011). A limitation, however, of the SRMR is decreased sensitivity within models with many parameters. Alkaline Information Criterion (AIC). AIC is a measures of the parsimony and quality of a specific model, and is used to compare multiple models (Burnham and Anderson, 2004; Kline, 2011). In general, models with lowest AIC values are preferred over those with larger statistics, which may indicate a number of parameters that do not contribute meaningfully to the model. However, these fit statistics are only meaningful in the context of model comparisons and are not interpreted on their own (Burnham & Anderson, 2004). In comparing models, Burnham and Anderson (2004) suggested that a model that differs by 10 or more on the AIC from another model is a very large difference, such that the model with the larger AIC is not likely to explain the relations within the data well. Subpopulation Analyses Upon testing the model with the full sample, the model was tested with both housing subgroups via the SUBPOPULATION command in Mplus. Testing the model with both groups allowed for testing the measurement and structural model with the two nested sub-populations of interest, the unstably housed and stably housed groups. As suggested within the literature (Brown, 2015; Kline, 2011; Reynolds & Keith, 2013), testing the model fit separately among the sub-populations of interest prior to multi-group analyses is a necessary step. In order for multigroup analyses to proceed, the model must demonstrate adequate fit to the sub-groups of interest in order to make meaningful comparisons of difference between competing models. A model that 78 shows poor fit to one group may require re-specification, as further detailed within the results section. Although weighting ensures representativeness of estimates to the larger sample and accounts for design structure, the focus of certain analyses on a sub-population (domain) within the larger data warrants adjustments to reflect the specific strata from which sampling occurred, therefore discarding cases not included in sample of the proposed study would likely produce biased estimates of standard error due to the sampling of the sub-population from several strata (Graubard & Korn, 1996). In order to obtain the most precise estimates of standard error, all observations were retained in the analyses and subpopulation commands were applied using housing status as the grouping variable. In Mplus and other similar software, this approach sets the weights of cases not within the subpopulation of interest to zero, while still retaining all design elements of the complex structure (Lee & Forthofer, 2006). Multi-group Structural Equation Modeling Once an adequate fitting model for both sub-populations was established, tests of measurement invariance were conducted. These series of tests included restricting factor loadings, intercepts and variances to establish that constructs were measured similarly across the two nested groups (Brown, 2015). Testing for measurement invariance consists of a series of steps that constrains components of the measurement model to test if underlying constructs function similarly across groups (Brown, 2015; Keith, 2014). Typically, the first step of invariance testing is establishing configural invariance in order to demonstrate that a similar model holds for both groups. Configural invariance includes specifying a model that is allowed to freely vary across groups, with the exception of latent means. Second, metric invariance is established by holding the factor loadings constant across 79 both groups. Metric invariance, also known as weak invariance, establishes that indicators of latent constructs function similarly for both groups (Keith, 2014; Meredith & Teresi, 2006). Next, scalar invariance, or strong invariance is established by constraining intercepts across groups. Establishing this form of invariance allows for mean level comparisons on latent variables with the assurance that mean differences are a result of underlying differences and not differences in the scales of the indicators (Keith, 2014). Although the last form of measurement invariance, strict invariance or constraints on residuals and covariances, is not considered necessary, this form of invariance was also tested with the full model. These forms of invariance ensure that error and covariances in the model do not affect cross-group comparisons (Brown, 2015). Measurement invariance was initially tested separately for each latent construct using the Mplus defaults (MODEL = CONFIGURAL METRIC SCALAR), followed by imposing constraints on the full model manually to also establish strict invariance and build a model for which to use for subsequent analysis. Upon establishing measurement invariance, the multi-group SEM (MG-SEM) with housing status (unstable vs. stable) as the grouping variable was applied to answer all research questions. MG- SEM includes the application of a series of constraints to test the fit of competing models to provide evidence of differential (moderation) group relations between components of the model. The questions were primarily concerned with examining structural differences between stably and unstably housed children and families across latent and observed means (RQ 2 & 3), direct paths (RQ 4), indirect paths (RQ 5), and moderated-mediation (RQ 6). Notably, only those paths with hypothesized differences in RQ 2- 6 were constrained and relaxed in an attempt to obtain a better fitting model that was comparable to baseline. Furthermore, to avoid multiple comparisons that could increase the potential for Type I errors, constraints were 80 applied in an omnibus fashion for each research question, as opposed to individually testing each parameter. The three primary steps of this approach for each set of paths of interest are described below. 1. Free Model: First, a model with all parameters allowed to vary freely was tested across both groups. This step establishes a baseline model for comparison of models tested in subsequent steps for this analysis. For example, to test the direct paths between parenting and children’s social-emotional skills, a model that first allowed these paths to freely vary in both groups was specified. 2. Constrained Model: The second step involved constraining parameters of interest for each research question (e.g., means, direct paths, indirect paths). This means these parameters were set as equal to one another. In the example highlighting a direct path of interest between parenting and social-emotional skills, this path was constrained for this phase of testing. The purpose of applying this constraint was to see if model fit changes. A comparable or improved fit would suggest two invariant models, which signifies little difference in the underlying structure of the model between the stably housed and unstably housed groups across paths. Conversely, if fit degrades, this would signify differential patterns of relations between the two groups. 3. Selective release of constraints: The third step involved selectively releasing constraints where differences were implicated by modification indices and difference testing for hypothesized paths in order to test if model fit changes. Using the example discussed above, if evidence of variance was found in Step 2, then the select paths that demonstrated variance would be released for comparison to the more restrictive model. 81 For the majority of the models (RQ 2-4), differences in the fit of competing models were tested using a likelihood ratio test for equality (chi-square difference test = Δχ 2 ) and changes in the CFI statistic (ΔCFI). For situations that required computing new parameters (moderatedmediation RQ 5-6), a similar test, the Wald Test (Wald X2), was used. Chi-square difference test = Δχ 2 : The chi-square difference test is a likelihood ratio test for equality that is conducted to examine if differences in model fit are statistically significant between competing models in multi-group analysis (Kline, 2011). This statistic was used to compare if the differences in chi-square between more constrained and relaxed models are statistically significant. Significance indicates group differences across the parameter or paths of interest. However, the most precise option for studies that employ Maximum Likelihood estimation methods is the Satorra-Bentler Chi-Square Test (S-B Δχ 2 , Satorra, 2000). Publicly available formulas through the developers of Mplus (https://www.statmodel.com/chidiff.shtml) were used to compute this statistic in Excel, as Mplus version 7.31 does not readily perform this test for structural invariance testing (Muthén & Muthén, 2015). These formulas are included in the Appendix. Difference in CFI (ΔCFI): Cheung and Rensvold (2002) proposed the use of additional fit criteria, such as the CFI, between competing models as an alternative to the chi-square statistic. CFI is less sensitive to sample size and has been frequently used in conjunction with the chisquare difference test in recent literature (e.g., Milfont & Fischer, 2015). Although the present study relied upon S-B Δχ 2 , differences in the CFI between models were also used as a supplementary metric by which to compare results. Using the cut-off criteria proposed by Cheung and Rensvold (2002), a difference in a CFI of .01 or higher between models was 82 considered significant. Similar to the S-B Δχ 2 test, significant differences in the CFI indicate evidence of variance between the paths/parameters of interest. Wald Test: In models with limited fit statistics and/or those that required the computation of new/additional parameters, the Wald Test (via the MODEL TEST command) was employed to detect if parameters were statistically different from one another or from the null hypothesis (β1 = β2, with β1 and β 2 as the same parameter across groups). Similar to other likelihood ratio tests, a non-significant Wald X2 indicates that the parameters may not statistically differ from one another. In the case of constraints, the Wald Test determines if additional parameters/constraints are significantly different from one another. Following the procedures above, targeted mean differences of interest for RQ 2 and RQ 3 in child outcomes, parent depression, and parenting practices between the unstably housed and stably housed groups were constrained upon establishing measurement invariance. Once means were constrained, the fit of this model was compared to a model where means were freely allowed to vary. Difference testing (S-B ΔX2 and ΔCFI), along with modification indices, were used to identify specific means that could be released in subsequent models. Standardized intercept differences were explored to consider the magnitude of mean differences on latent constructs between the two groups. RQ 4 was aimed at specific differences of the direct paths of environmental quality indicators to child outcomes. All six direct paths of interest (parent engagement à socialemotional functioning; parent engagement à language and literacy; parent approaches à socialemotional functioning; parent approaches à language and literacy; parent depression à socialemotional functioning; parent depression à language and literacy) were constrained to compare model fit to the best fitting model from the previous research question. Difference testing (S-B 83 ΔX2 and ΔCFI) and modification indices were examined to consider differential predictive relations between the two groups. RQ 5 tested differences in the four hypothesized indirect relations of parenting approaches and engagement on the relationship between caregiver depression and children’s outcomes. Differences in the mediational paths between the groups were considered in two ways. First, all direct paths that comprised the mediational paths were constrained and compared to the best fitting model from the previous research question. Since mediation is the product of two direct effects, differences in the indirect path would be seen on one or both of the direct paths that comprise the indirect effect. Second, differences in mediational paths across groups was also tested by the Wald X2. For this approach, new parameters that reflected the indirect effect were created through the MODEL CONSTRAINT command for each group (Muthén & Muthén, 2015). Then, the indirect effects in both groups were set as equal to one another to test if the indirect effects differentially contributed to the model for the stable and unstably housed groups. Lastly, RQ 6 targeted differences in the moderated-mediation. Due to the addition of the latent variable interaction, an alternative method to multiple group analysis that used latent class mixture model within two known classes (or observed variable) was required to answer this final research question. Traditional multi-group analyses in Mplus lacks the capability to handle latent variable interactions, however mixture modeling that uses an observed class variable (e.g., KNOWNCLASS command) is identical to the multi-group approach when an observed variable is used to classify the groups, but allows for latent variable interactions (Muthén & Muthén, 2015). Differences in model fit were compared using parsimony fit statistics (e.g., AIC) and the Wald Test. 84 Post-hoc Analyses Additionally, the analytic plan included exploratory post-hoc analyses, such as Analysis of Variance (ANOVA), to better explain the challenges that arose during data analysis. More specifically, the post-hoc analysis sought to gain insight into the relations between maternal race and housing due to degraded model fit as a result of including race as a covariate for the unstably housed group, as detailed in the results section. 85 CHAPTER 4 RESULTS Preliminary Analyses Preliminary descriptive statistics and analyses are presented in Tables 6- 9. Table 6 presents the unweighted and weighted descriptive statistics of the full pre-kindergarten sample. Tables 7 and 8 include descriptive statistics by housing status and preliminary univariate significance testing (e.g., t-test) for mean differences.

However, this testing revealed some differences between the unweighted and weighted results. The unweighted results (Table 8) indicated significant differences in mean levels of parental depression between the stably housed (M= 3.45 SD = 5.03) and unstably housed (M= 4.33 SD= 5.67) groups; t(562.33)= -2.00, p<.05. Parents who were unstably housed during Head Start reported higher levels of depression symptoms. In addition, significant differences in parent reported problem behaviors emerged between the unstably housed (M= 18.29 SD = 4.02) and stably housed (M= 18.99 SD= 3.57) children; t(565.7),= 2.76 p <.01, such that parents of children who were stably housed during Head Start endorsed higher mean levels of problem behaviors. Consistent with the unweighted results, the weighted (Table 9) results suggested mean level differences in parent reported problem behaviors between the two groups; t(48)= 2.05 p < .05. However the weighted results indicated differences in mean scores of the authoritative parenting sub-scale between the unstably housed (M= 3.45 SE = .03) and stably housed (M= 3.51, SE = .02 ) parents; t(48)= 2.01 p<.05. Although the difference between the two groups was not significant when the data were weighted, parental depression scores continued to suggest that unstably housed parents were more likely to endorse slightly higher levels of depressive symptomology. These preliminary results should be interpreted with caution, as multiple comparisons increase the likelihood of Type I error. Differences in the covariates, the economic risk index, maternal race, child’s gender, and child’s age at entry, were also explored. Unweighted chi-square testing indicated significant differences in economic risk between the two groups, χ2 (3, N = 1440) = 16.98, p <.001. 91 Weighted percentages signified that unstably housed children were more likely than stably housed children to face one (35% versus 29%) or two (48% versus 37%) indicators of economic risks at the time of pre-kindergarten data collection. Similarly, chi-square testing suggested differences in the distribution of families across the two groups by maternal race, χ2 (3, N = 1508) = 13.10 p <.005. An examination of weighted percentages indicated that mothers who experienced housing instability were more likely than stably housed counterparts to be White (33% versus 24%) or Latino (40% versus 36%). There were no significant differences between groups with respect to child’s gender or age at entry into Head Start. Correlations. Correlations (Table 9) were examined for exploratory group differences in associations between the study variables. Although similar associations were found among both groups, several noteworthy differences emerged. One difference that emerged was the greater number of associations between parental depression symptoms and parenting, as well as depression and child behavior for the stably housed group. More specifically, depression symptomology was significantly correlated with warmth (r= -.08, p<.001), energy (r= .-.12, p <.001), authoritarian parenting (r= -.09, p<.001), parent-reported behavior (r= -.23, p<.001), parent-reported social skills (r= -.12, p<.001), and teacher-reported social skills (r= -.10, p<.001) scores for the stably housed group. For the unstably housed group, depression was significantly correlated with only parent-reported behavior (r= -.20, p<.001). In addition, parental involvement in Head Start was significantly correlated with the classroom organization sub-scale of the Classroom Assessment Scoring System (r=-.15, p<.001) for the unstably housed group, whereas this difference was close to zero and non-significant among the stably housed group (r= -.01, p<.001). Furthermore, teacher-reported social skills were significantly related to both receptive (r= .16, p <.001) and expressive language (r= .19, p<.001) in the unstably housed 92 sample, whereas these differences were non-significant among the stably housed group (r= .04 and .02, p<.001). Measurement Model Confirmatory factor analysis (CFA) was first conducted on the full sample to assess the proposed five-factor structure of the model. The measurement portion of the model specified five latent constructs: parent approaches, parent engagement, classroom quality, social-emotional functioning, and language and literacy. Parent approaches was specified by four sub-scale scores from the parenting questionnaire: warmth, authoritative, authoritative, and energy. Parent engagement was specified with three indicator scores: monthly out-of-home activities, weekly parent-child activities, and involvement in Head Start. Classroom quality was specified with the three sub-scales process quality (emotional support, instructional support, and classroom organization) and the structural quality score. Social-emotional functioning was specified by the two broader behavioral composites for the parent-reported items (problem behaviors and social skills) and the two behavioral composite scores for the teacher-rated items (problem behaviors and social skills). Lastly, the language and literacy construct was indicated by receptive language, expressive language, and letter-word identification. The fit of the initial five-factor structure fit the data reasonably well, RMSEA = 0.048, 90% CI = 0.044 -.052, CFI = 0.872, SRMR = .060, χ2 = 572.82, p = 0.0, df = 125. As previously noted, it was expected that the chi-square fit statistic would be significant due to the large weighted sample (Kline, 2011). Although this value is reported throughout, additional fit indices (e.g., CFI, RMSEA, SRMR) were primarily used to make statistical decisions. Changes to the initial five-factor structure were identified using modification indices, communalities (R2) and fit statistics. Salient theoretical considerations were used in conjunction with statistical evidence. 93 However, modifications to theoretical models are considered exploratory and results should be interpreted with caution (Brown, 2015). In the present study, modifications were allowed in order to include a preliminary exploration of a more complex model with an understudied group of unstably housed children. Two main modifications were made to the measurement model. First, the authoritative approaches score was removed from the model. Decisions to remove factors occur in light of theoretical and statistical significance. In general, indicators with standardized loadings below .30, low communalities, and/or non-significant contributions are typically removed (Brown, 2015). Authoritative parenting demonstrated a low loading (.20) and very low communality (R2= .05), indicating that this sub-scale contributed little to the construct and model, despite demonstrating a significant loading. Consistent with the broader literature, modification indices were used sparingly and only when they were conceptually meaningful to avoid contributing to atheoretical and/or over-fitted models (Brown, 2015; Joreskog, 1993). Modification indices suggested three conceptually justifiable changes. Although a primary assumption of CFA is that the observed variables are measured without error, three residuals between indicators from the same measure were included in the model. These modifications were deemed as reasonable due to the scores originating from the same broader measure, thus likely increasing the chance that specific indicators have more similarity with other indicators of the construct. The three additional terms allowed to co-vary included teacher-rated social skills with teacher-rated problem behaviors, classroom instructional support with classroom organization, and authoritarian parenting with energy. Two additional noteworthy changes were explored, but ultimately not included in the model. First, a cross-loading of parental energy with both the parent approaches and parent 94 engagement latent variables. This potential cross-loading was identified via modification indices and appeared theoretically plausible because of select items (e.g., adhering to plans) that may be pertinent to both parental approaches and engagement. Furthermore, correlations (Table 9) indicated that associations between energy and indicators of parent engagement (e.g., weekly activities) were moderate. When cross-loaded, energy loaded significantly on both constructs and model fit improved slightly, however, energy was retained as an indicator of parent approaches due to a low cross-loading on parent engagement (<.10). Second, models in which social-emotional indicators were considered as both separate constructs by rater and as one unidimensional construct were explored. Although there was an improvement in the measurement model in which social-emotional constructs were separated by rater (RMSEA = 0.034, 90% CI = 0.028 -.037, CFI = 0.940, SRMR = .040, χ2 = 267.68, p = 0.0, df = 102), the unidimensional social-emotional model was ultimately selected (RMSEA = 0.035, 90% CI = 0.031 -.040, CFI = 0.938, SRMR = .047, χ2 = 312.48, p = 0.0, df = 106) in favor of parsimony with regards to the structural paths of the model, given the complexity of the full model. Although teacher-rated social skills demonstrated a marginally low loading (.26) with social-emotional functioning as a unidimensional construct, this indicator was retained in the model due to the marginal contribution to the model and in order to maintain a cohesive construct balanced by both parent and teacher-report. The final five-factor measurement model fit the data well, RMSEA = 0.035, 90% CI = 0.031 -.040, CFI = 0.938, SRMR = .047, χ2 = 312.48, p = 0.0, df = 106. All loadings were significant and fit statistics indicated improvement in model fit from the baseline measurement model. Information on the specific loadings of each indicator is summarized in Table 10. Although tests of measurement invariance are detailed in subsequent sections, preliminary 95 subpopulation analyses indicated that the measurement model demonstrated adequate fit with both the stably housed (RMSEA = 0.039, 90% CI = 0.034-.044, CFI = 0.930, SRMR = .050, χ2 = 289.62, p = 0.0, df = 106) and unstably housed (RMSEA = 0.049, 90% CI = 0.039-.050, CFI = 0.912, SRMR = .063, χ2 = 200.56, p = 0.0, df = 106) sub-groups.

Model fit was used to determine the appropriateness of proceeding with multi-group analyses, as each model was tested with the full sample and the two housing sub-groups separately to make decisions about subsequent steps. Due to a lack of 96 availability of traditional model fit indices, latent variable moderation was included only in the final model and compared using fit indices of parsimony (AIC). Model fit indices throughout the development of the structural model phase are summarized in Table 11. The base mediational model fit the full sample well, RMSEA = 0.035, 90% CI = 0.030 .039, CFI = 0.937, SRMR = .046, AIC = 114295.61, χ2 = 342.77, p = 0.0, df = 120. Similarly, the base model fit the stably housed group well, RMSEA = 0.038, 90% CI = 0.033 -.043, CFI = 0.929, SRMR = .050, AIC = 83635.29, χ2 = 314.13, p = 0.0, df = 120. The model also demonstrated adequate fit with the unstably housed sample, RMSEA = 0.046, 90% CI = 0.036.052, CFI = 0.915, SRMR = .061, AIC = 2725.39, χ2 = 214.27, p = 0.0, df = 120. Model with Covariates Next, a model that included hypothesized covariates was specified. Categorical covariates were dummy coded for inclusion in the model. Based on theoretical considerations, paths from the economic risk index categories to depression, parent engagement, parent approaches, and language and literacy were included. Paths from maternal race to depression, parent approaches, and parent engagement were included. Paths from gender to behavior, parent approaches, and parent engagement were included. Lastly, paths from child’s age at Head Start entry to parent approaches, parent engagement, behavior, and language and literacy were included. Ultimately, age was trimmed from the model due to not significantly contributing to any of the specified variables. This change appeared reasonable given that the sample was heterogeneous with regards to age due to the focus of the study on the pre-kindergarten year and the sample was relatively balanced by cohort. All other pre-specified paths were initially retained. With the addition of the covariates, the model fit dropped considerably. The fit of the model for the full sample was marginal, but 97 adequate, RMSEA = 0.039, 90% CI = 0.036-.042, CFI = 0.886, SRMR = .046, AIC = 122608.54, χ2 =719.56, p = 0.0, df = 214. Fit statistics continued to indicate similar fit for the stably housed group, RMSEA = 0.039, 90% CI = 0.036-.043, CFI = 0.889, SRMR = .046, AIC = 89808.34, χ2 = 592.97, p = 0.0, df = 214. However, model fit was poorer, with a noted drop in several fit indices (CFI, RMSEA and SRMR) for the unstably housed group, RMSEA = 0.052, 90% CI = 0.045-.059, CFI = 0.846, SRMR = .064, AIC = 29003.16, χ2= 427.01, p = 0.0, df = 214. Due to the considerable degradation of model fit with the addition of the covariates, especially for the unstably housed group, model re-specification was targeted at the covariates. Covariates were tested separately and results indicated that maternal race was responsible for the greatest degradation in model fit, particularly for the unstably housed group. Although the inclusion of this variable was both theoretically and statistically significant with regards to depression and parenting, the model was re-specified without maternal race in order to proceed with multi-group analyses. However, proceeding without this covariate warranted caution in interpretation. Possible causes for the degradation in model fit as a result of this variable in relation to the measurement components of the model are explored further in the post-hoc analysis section to support interpretation of the final results. The re-specified model fit the data well, RMSEA = 0.034, 90% CI = 0.031-.038, CFI = 0.93, SRMR = .043, AIC = 119930.38, χ2 = 491.69, p = 0.0, df = 175. Fit indices also indicated reasonably well-fitting model for the sub-groups. The model fit the stably housed group adequately, RMSEA = 0.035, 90% CI = 0.030-.039, CFI = 0.922, SRMR = .045, AIC = 87793.62, χ2 = 415.63, p = 0.0, df = 175. Model fit was also adequate for the unstably housed group, RMSEA = 0.046, 90% CI = 0.038-.050, CFI = 0.886, SRMR = .058, AIC = 28558.72, χ2 98 = 312.99, p = 0.0, df = 175. Despite some borderline fit indices for the unstably housed group (e.g., CFI below .90), this model was used for subsequent analysis to retain the majority of constructs of interest, as a primary aim of the study was to examine the role of housing instability beyond economic risks in the proposed relations. Therefore, analysis was centered around preserving as many paths and covariates of theoretical interest as feasible.

Standard error estimates were derived using Taylor Series Linearization. Figure 4 summarizes the standardized estimates for the full model. See Table 12 for a summary of standardized and unstandardized parameter estimates, as well as standard errors for each parameter in the full moderation model. 99 Two covariates, the family economic risk index score and child’s gender, were included in the final model. Using the highest risk group as the reference, economic risk index scores were significantly related to parental depression and children’s language and literacy scores. Specifically, parents of children with the lowest levels of economic risk were less likely to endorse depressive symptoms (βrisk0 = -.11, p<.001; βrisk1 = -.07, p<.05) and their children scored higher on standardized academic measures (βrisk0 = .27, p<.001; βrisk1 = .25, p<.001; βrisk2 = .14, p<.005) when compared to those facing the greatest risk. Furthermore, child gender was significantly related to behavior ratings, such that parents and teachers rated males lower on the latent construct of social-emotional functioning (β = -.24, p <.001). The majority of the direct effects specified in the model were significant. Parental depression significantly predicted parental approaches (β = -.17, p <.001), which suggested that higher rates of depression negatively influenced the construct of parental approaches. Contrary to expectations, however, parental depression was positively related to parent engagement (β = .08, p <.05), such that higher parental depression scores predicted slightly higher levels of engagement. However, while significant, this relation had a relatively lower significance level (p <.05) compared to parent depression and parental approaches. Depression was also directly related to children’s skills in the areas of social-emotional functioning as expected, such that parental endorsement of depressive symptoms was negatively related to the latent construct of social-emotional functioning (β = -.25, p <.001). Unexpectedly, endorsement of depressive symptoms was predictive of higher levels of the latent construct of language and literacy (β = .08, p < .005). As expected, parental approaches and parent engagement were positively related to social-emotional functioning (βapproaches = .35 , p <.001 ; βengagement = .27, p <.001), as well as 100 language and literacy (βapproaches = .25, p <.001 ; βengagement = .11 , p <.05). Other theorized direct associations between classroom quality and child functioning were non-significant. Overall, evidence of moderated-mediation was not supported with the full prekindergarten sample. Results suggested that the moderated-mediation model was a slightly worse fitting model (AIC = 119931.64) than the base mediational model (AIC = 114295.61). Partial mediation, specifically the influence of parental depression on children’s social emotional functioning through parent approaches (βindirect = -.06, p < .001) and language and literacy through parent approaches (βindirect = -.04, p < .001) were supported by the results. These relations indicated small, but significant relations such that that higher depressive symptoms were related to lower quality parenting practices, which in turn negatively predicted children’s social-emotional and academic skills. Yet, parent approaches partially mediated the association between depression and children’s outcomes, as the direct relationships between depression and child functioning remained significant (β = -.25, p <.001; β = .08, p < .005). As noted above, classroom quality did not further moderate the indirect paths, suggesting that the level of classroom quality did not impact the existing indirect influence of parental approaches in the relation between parental depression and child functioning. Parent engagement positively partially mediated the relation between depression and children’s social-emotional functioning (βindirect = .02, p < .05). This relation was unexpected, however, as the results suggested that higher levels of depressive symptoms positively predicted engagement, which in turn was related to positive social-emotional functioning. Similar to parental approaches, the standardized indirect effect was small in magnitude. The relation between parental depression and latent construct of language and literacy via parental engagement was non-significant. 101 Table 12: Parameter Estimates and Standard Error for Moderated-Mediation Model for Full Sample Unstandardized Standardized Standard Error (SE) 1.00 0.55** 0.77** 0.69** 0.55** 0.55** 0.05 0.04 0.04 1.00 0.75** 0.85** 0.71** 0.64** 0.47** 0.04 0.04 0.04 1.00** 0.96** 0.71** 0.98** 0.94** 0.76** 0.55** 0.63** 0.04 0.05 0.06 0.04 1.00 1.09** 0.51** 0.91** 0.86** 0.50** 0.02 0.02 0.02 1.00 0.52** 0.60** 0.52** 0.64** 0.49** 0.33** 0.29** 0.05 0.06 0.05 0.05 -0.02** 0.02* 1.65** 6.72** 0.40** 0.92* -0.11** 0.21* 0.12 1.05 -0.17** 0.08* 0.35** 0.25** 0.28** 0.11** -0.25** 0.08* 0.02 0.04 0.03 0.03 0.06 0.03 0.05 0.05 0.05 0.03 0.05 0.04 -0.11** -0.04** 0.01 Factor Loadings Parent Approaches Energy Warmth Authoritarian Parent Engagement Monthly Activities Weekly Activities Head Start Involvement Classroom Quality Emotional Support Organization Instructional Support Structural Quality Language & Literacy Expressive Language Receptive Language Pre-literacy Skills Social-Emotional Functioning Parent-Reported Problem Behaviors Parent-Reported Social Skills Teacher-Reported Problem Behaviors Teacher-Reported Social Skills Direct Effects Depression à Approaches Depression à Engagement Approaches à Social-Emotional Approaches à Language & Literacy Engagement à Social-Emotional Engagement à Language & Literacy Depression à Social-Emotional Depression à Language & Literacy Classroom Quality à Social-Emotional Classroom Quality à Language & Literacy Indirect Effects (Mediation) Depression à Approaches à Language & Literacy 102 Table 12 (cont’d) Depression à Approaches à Social Emotional Depression à Engagement à Social-Emotional Depression à Engagementà Language & Literacy Interactions (Moderated-Mediation) Approaches X Classroom Quality à Language & Literacy Approaches X Classroom Quality à Social-Emotional Engagement X Classroom Quality à Language & Literacy Engagement X Classroom Quality à Social-Emotional ** p value <.001 * p value <.05 Figure 4: Moderated-Mediation Model Full Sample 103 -0.03** 0.02* 0.01 -0.06** 0.01* 0.02 0.02 0.01 0.01 -3.08 0.56 0.56 -0.01 -0.06 0.06 0.03 0.00 0.05 0.06 0.04 0.04 Structural Model with Subpopulations The same full structural model was tested with both sub-groups. The stable and unstable groups (Figure 5) demonstrated a similar pattern of results for significant paths as the larger prekindergarten sample and evidence of moderated-mediation did not emerge among either group. However, some differences emerged between the two groups when models were tested separately. With regards to covariates, parents of children who faced lower risk were more likely to display greater levels of engagement on the latent construct of engagement (βrisk0 = 1.39, p<.05; βrisk1 = 1.42, p<.005; βrisk2 = 1.20, p<.05), whereas this covariate was not significant for the stably housed group. On the contrary, risk was not predictive of parental approaches among the unstably housed group, whereas among the stably housed parents facing less risk (one economic risk factor) reported higher scores on the latent construct of parental approaches compared to those facing the greatest risk (βrisk1 = .14, p<.05). Within the hypothesized model for the unstably housed group, the indirect paths between depression and children’s outcomes via parent engagement (βindirectsocial-emotional = .01, p < .33; βindirectlanglit = -.01, p = .42) were non-significant for the unstably housed group, whereas the social-emotional path remained only marginally significant for the stably housed group (βindirectsocial-emotional = .02, p = .053). Furthermore, classroom quality was directly related to children’s social-emotional functioning for children who experienced housing instability during Head Start (β = .27, p < .05) such that higher classroom quality scores were predictive of increases in social-emotional functioning. In contrast, this relation did not emerge for the stably housed group or among the full sample. All other paths and factor loadings were comparable between the two groups and to the full pre-kindergarten sample. Multi-group analysis was 104 conducted in subsequent steps to indicate if differential relations across groups in model parameters were significant. 105 Figure 5: Standardized Estimates for Sub-Groups for Full Model 106 Multiple Group Analyses Multiple group analyses were utilized to test for significant differential relations in the hypothesized model between stably housed and unstably housed children. The initial step of multiple group analyses included testing for measurement invariance. This step is necessary prior to testing for structural differences between groups, including latent means and paths. Upon establishing measurement invariance, structural paths were constrained and relaxed to evaluate changes in model fit. The following section details measurement invariance testing, followed by constraining and relaxing paths of theoretical interest as aligned with research questions. Measurement Invariance Each of the latent constructs were initially tested for configural, metric, and scalar invariance separately to determine possible sources of variance across the general structure of the constructs, factor loadings, or intercepts between the unstably and stably housed groups. Individual tests of invariance are summarized in Table 13. Each of these tests included testing subsequently more restrictive models, ultimately holding factor loadings and intercepts constrained (scalar invariance). Constructs that are invariant in their loadings and interprets are understood to demonstrate strong invariance (Meredith, 1993; Kline, 2011). Results supported evidence of strong invariance for individual tests, such that difference testing using the S-B Δχ2 and ΔCFI were non-significant across more restrictive models for each of the latent constructs, demonstrating that each of the five latent constructs were invariant across the stably housed and unstably housed groups. This suggested that the underlying constructs had similar factor structures and underlying meanings for both groups. Measurement invariance testing was also conducted with the full model in order to develop a baseline model from which to compare model fit for subsequent analyses. All MG- 107 SEM analyses are summarized in Table 14. In order to establish support for strict invariance, the optimal form of measurement invariance that allows for comparisons of the structural components of the model between groups, establishing measurement invariance with the full model consisted of testing five models. Following recommendations from the literature (e.g., Brown, 2015; Keith, 2014), these included the following: 1. an equal form model with all parameters (with the exception of means) allowed to vary freely between the groups (configural invariance) 2. a model with factor loadings held equal (metric invariance) 3. a model with factor loadings and intercepts held equal (scalar invariance) 4. a model with residual variances held equal and 5. a model with residual covariances held equal. Results supported strict invariance. The initial model (configural invariance model) demonstrated adequate fit to the data (χ2 = 754.92, p = 0.00 ,df = 350, RMSEA = .039, 90% CI = 0.05-.043, CFI = 0.911, SRMR = .049, AIC = 116367.48). When factor loadings were constrained to be equal across groups (Model 1), the difference in model fit between Model 0 and Model 1 was non-significant, S-B ΔX2 (12) = 1.02, p= .99; ΔCFI = .004. Similarly, differences between Model 1 and Model 2, in which intercepts were also constrained to establish scalar invariance was also non-significant, S-B ΔX2 (12) = 7.44, p = .83; ΔCFI = .002. Criteria for strict invariance, residual variances (Model 3) and covariances (Model 4), were set to be equal across groups. The difference in model fit between the scalar model (Model 2) and the model with restricted residual variances (Model 3) was non-significant, S-B ΔX2 (17) = 16.94, p = .46; ΔCFI = .000. Similarly, when residual covariances were also constrained (Model 4), the difference in fit between Model 3 and 4 was also non-significant, S-B ΔX2 (4) = 4.52, p = .34; ΔCFI = .000. Together, results established that the underlying measurement components of the 108 model are invariant between the stably housed and unstably housed groups, allowing for meaningful comparisons of the structural components of the model between the two groups. Research Questions 2 & 3: Mean Differences Due to the model meeting strict invariance, latent mean differences were examined in the multi-group framework. Using the residual covariance model (Model 5), the means of interest for research questions 2-3 were constrained in an omnibus fashion in Model 6. Means of relevance included constructs relevant to parenting (RQ 2) and child outcomes (RQ 3), including parental approaches, parental engagement social-emotional functioning, language and literacy, as well as the observed mean of parental depression. The Satorra-Bentler chi square test indicated a significant degradation in model fit between the residual covariance model (Model 4) and the constrained mean model (Model 5), S-B ΔX2 (6) = 13.52, p = .04. However, the difference in CFI (ΔCFI = .001) indicated non-significant differences between the two models. Modification indices were used to identify potentially significant improvements in model fit. These indices suggested the release of constraints on the parent engagement intercept or mean of the latent construct of parent engagement. Model 6 included relaxed constraints on parent engagement and was compared again to Model 4. Relaxing constraints on the latent construct of parent engagement (Model 6) resulted in comparable and non-significant changes in model fit, ΔX2 (5) = 4.35, p = .50; ΔCFI = .002, suggesting Model 5 (latent mean of parent engagement free) was the better fitting model. Using the stably housed group as the reference group, the standardized mean difference was -.91 (z = -2.98), suggesting that the unstably housed parents were significantly less likely than their stably housed counterparts to participate in forms of parent engagement as captured by the latent construct. 109 Research Question 4: Direct Paths For RQ 4, all relevant paths from parenting constructs to child outcomes, as well as classroom quality to child outcomes were constrained to evaluate for differential influence of housing instability across direct paths. Although sub-population analyses that examined the model separately in each group suggested potential differences in direct paths from parent engagement to child outcomes and from classroom quality to behavior, the model with these direct paths constrained (Model 7) demonstrated non-significant differences with the model in which the intercept of parent engagement was freed (Model 6), ΔX2 (8) = 11.04, p = .20; ΔCFI = .001, suggesting no significant differences in the predictive relations between parenting and child outcomes or classroom quality and child outcomes between the two groups. Research Question 5: Indirect Paths for Mediation First, to answer RQ 5, all direct paths that comprised the indirect mediational paths relevant to the mediation were constrained. This involved constraining an additional two paths from the previous model (parent depression à parent engagement and parent depression à parent approaches). The model with all mediational paths constrained (Model 8) was compared to the previous model (Model 7). Model fit was comparable and changes in fit were nonsignificant, ΔX2 (2) = 1.00, p = .61; ΔCFI = .000, suggesting that the paths that comprised the mediational effect were invariant across two groups. Additionally, differences in the indirect paths between the two groups were also tested using the Wald Test statistic, such that equality constraints posed upon the new parameters that contributed to the hypothesized mediation were set as equal to one another (βindirectstable = βindirectunstable). The significance in difference between the constraints were then tested using the Wald χ2, which confirmed the previous results that there were non-significant differences in the 110 mediational paths between the stably housed and unstably housed groups, Wald χ2(4)= 3.24, p = .52. Research Question 6: Moderated-Mediation Despite a lack of significance of the moderation in the full sample or in the subpopulation analyses, differences in moderated-mediation were tested as part of multi-group analyses to explore for potential group differences in the magnitude of the effect. As detailed in the methods, moderated-mediation within multi-group analyses is tested using known class mixture modeling. Difference testing between the two groups was conducted using the limited available fit statistics (e.g., AIC) under the numerical integration algorithm and the Wald χ2 was further used to compare the equality of the constraints imposed upon on the parameters of interest. Specifically, a model with constraints on the paths relevant to the moderation (Model 9) was compared to a model in which the moderation was allowed to vary freely (Model 10). Model 9 was suggestive of a slightly lower AIC (118015.20) in comparison to Model 10 (118021.96), or a ΔAIC of 6.76, indicating that the moderated-mediation model with constraints was a better fitting model. In other words, the moderation did not have appear to exert a differential effect across the groups. Second, the Wald Test statistic was used to compare the equality of the constraints imposed upon the moderation paths. The results re-iterated the previous findings, such that the differences across moderation paths were non-significant across the two groups, Wald X2(2)= .99, p = .61. 111 Table 13: Construct-Level and Measurement Model Invariance Testing Parenting Approaches Configural Metric Scalar Parent Engagement Configural Metric Scalar Classroom Quality Configural Metric Scalar Language & Literacy Configural Metric Scalar Social-Emotional Functioning Configural Metric Scalar Measurement Model Configural Metric Scalar X2 CFI ΔCFI SB ΔX2 Δdf P value Models Compared 0.00 1.79 1.67 1.00 1.00 1.00 -.000 .000 -1.76 0.19 -2 2 -.42 .91 -Configural vs. Metric Metric vs. Scalar 0.00 1.10 2.41 1.00 1.00 1.00 -.000 .000 -1.10 2.41 -2 2 -.57 .52 -Configural vs. Metric Metric vs. Scalar 14.25 21.67 25.99 .981 .972 .970 -.009 .002 -3.81 1.59 -3 3 -.28 .67 -Configural vs. Metric Metric vs. Scalar 0.00 1.08 4.51 1.00 1.00 .990 -.000 .001 -1.08 3.58 -2 2 -.58 .17 -Configural vs. Metric Metric vs. Scalar 0.30 2.03 3.96 1.00 1.00 1.00 .000 .000 .000 -2.10 1.81 -3 3 -.55 .61 -Configural vs. Metric Metric vs. Scalar 495.10 506.38 511.95 .926 .927 .928 -.001 .001 -11.41 7.65 -12 12 -.49 .81 -Configural vs. Metric Metric vs. Scalar 112 Table 14: Multi-Group Analysis Model Summary Table Measurement Invariance Model 0: Configural (all free) Model 1: Metric (factor loadings) Model 2: Scalar (intercepts) Model 3: Residual Variances Model 4 : Residual Covariances Means (RQ 2 & 3) Model 5: Means Constrained Model 6: Parent Engagement Free Direct Paths (RQ 4) Model 7: Direct Paths Constrained Indirect Paths (RQ 5) Model 8: All Paths of Mediation Constrained Moderated-Mediation (RQ 6) Model 9: Moderated-Mediation Constrained Model 10: Moderated-Mediation Free X2 CFI ΔCFI S-BΔX2 Δdf P value Wald χ2 P value Models Compared 745.92 .911 -- -- -- -- -- -- -- 740.82 .915 .004 1.10 12 .99 -- -- Model 0 vs. Model 1 745.19 .917 .002 7.43 12 .83 -- -- Model 1 vs. Model 2 760.62 .917 .000 16.95 17 .46 -- -- 764.36 .917 .000 4.52 4 .34 -- -- Model 2 vs. Model 3 Model 3 vs Model 4 778.41 .916 .001 13.52 6 .04* -- -- 768.13 .918 .002 4.35 5 .50 -- -- 778.95 .917 .001 11.04 8 .20 -- 779.46 .917 .000 1.00 2 .61 3.24 .52 -- -- -- -- -- -- -- -- -- -- -- -- -- -- .99 .61 113 -- Model 4 vs. Model 5 Model 4 vs. Model 6 Model 6 vs. Model 7 Model 7 vs. Model 8 Model 9 vs. Model 10 Post-hoc Analyses Post-hoc analyses were focused on identifying sources of variation related to degradations in fit for the model with maternal race and univariate relations between race and housing status. Due to the degradation in overall model fit, but significant contributions of race in the structural model, the possibility of differences in the measurement model across latent constructs with race as the grouping variable (White, African American, and Hispanic/Latino) was explored. These exploratory results indicated that that although a similar model and factor loadings held across groups (configural vs. metric S-B ΔX2 (24) = 35.95, p = .06; ΔCFI = .001), intercepts were variant across groups. Specifically, there were significant differences between models that held factor loadings (RMSEA = 0.049, 90% CI = 0.044-.053, CFI = 0.894, SRMR = .073, χ2 = 758.31, p = 0.0, df =351) and intercepts (RMSEA = 0.062, 90% CI = 0.057-.066, CFI = 0.827, SRMR = .091, χ2 = 1074.67, p = 0.0, df = 375) equal to one another, S-BΔX2 scalar vs. metric (24) = 258.13, p = .00; ΔCFI = .07. Intercept variance across measurement components of the model suggests differential meaning of latent constructs by race. Thus, group comparisons that include race with latent constructs described in the study may be uninterpretable or must be interpreted with caution. Further testing to examine partial invariance extended beyond the scope of the current study and was not conducted. However, the lack of invariance by maternal race may be one reason for the degradation in model fit when race was included as a covariate. In addition, a series of univariate Analysis of Variance (4 X 2 ANOVA) using SPSS Complex Samples (General Linear Model) were conducted to consider race (1= White, 2= Black, 3= Hispanic/Latino, 4 = Other) by housing (0= Stably Housed, 1 = Unstably Housed) interactions across the indicators of the model. A significant interaction emerged between race and housing status with regards to teacher-rated problem behaviors, F(3, 46) = 3.94, p <.05. 114 Using non-reverse coded scores for which lower scores indicated fewer problem behaviors, results suggested differential patterns across racial groups by housing status (Figure 6). Among both groups, children of mothers who identified as Hispanic/Latino were rated to have the fewest behavioral problems by teachers, but this difference was more pronounced for children who were also unstably housed at any point in Head Start (Mstable = 3.28, Munstable= 2.54). Furthermore, children of African American mothers among the unstably housed group were rated to exhibit higher problem behaviors in the classroom by teachers (Mstable= 3.67, Munstable = 5.81). No additional interactions (race x housing status) emerged across parenting practices, depression scores, child behavioral ratings, or child assessment measurements. However, main effects of race emerged for several indicators included in the model. With regards to parenting variables, significant main effects were found across scores for weekly activities (F(3, 46) = 29.02 , p <.001), monthly activities (F(3, 46) = 16.84, p <.001), and parental depression symptomology (F(3, 46) = 15.16, p <.001). Specifically, mothers who identified as Hispanic/Latino reported the lowest mean levels of depression (M= 2.77), whereas those who identified as African American reported the highest depression scores (M= 5.45). Furthermore, mothers who identified as Hispanic/Latino reported fewer weekly activities (M= 11.01), whereas all other groups reported comparable mean levels of weekly activities (~12). Mothers who identified as Black/African American or Other reported the highest number of out of home monthly activities (Mblack= 6.09, Mother= 5.78), whereas those who identified as White or Hispanic/Latino reported similar levels of monthly engagement activities (Mwhite= 4.51, Mlatino= 4.80). In addition, main effects for race were present among receptive (F(3, 46) = 43.70, p <.001) and expressive language (F(3, 46) = 16.46, p <.001). Children of mothers who identified as White scored highest on tests of expressive (Mwhite= 89.12, Mblack = 83.21, Mlatino = 80.31, 115 Mother= 80.60) and receptive language (Mwhite= 97.74, Mblack = 89.49, Mlatino = 77.15, Mother= 89.06) in comparison to all other groups. Lastly, main effects were present by race (F(3, 46) = 5.03, p <.05) and housing (F(1, 48) = 1.39, p <.05) for parent-rated problem behaviors. Children of mothers who identified as Hispanic/Latino (Mwhite= 5.03, Mblack = 4.77, Mlatino = 6.14, Mother= 5.97) or were unstably housed (Mstable = 4.96, Munstable= 6.00) reported more problem behaviors. Due to large number of univariate tests and the increase in the Type I error rate, these differences should be interpreted as exploratory. Figure 6: Teacher-Rated Problem Behavior Scores by Maternal Race and Housing Status 116 CHAPTER 5 DISCUSSION Early childhood appears to be a particularly sensitive period for the effects of housing instability (Fowler et al., 2014). In particular, the pre-school years are especially salient, in light of the wide literature-base on school readiness that suggests that skills at formal school entry are predictive of longer-term functioning (e.g., Duncan et al., 2007). The Family Stress Model and Risk/Resilience highlight the important role of social context in hindering and fostering school readiness and early development for children experiencing poverty and housing instability. The Family Stress Model illustrates the importance of parenting practices to children’s functioning and suggests that poverty fosters a context that affects parenting through the increased risk for parental depression (Conger et al., 2002). Although research has found that parents who experience housing instability may be at higher risk for depression and lowered levels of specific parenting practices, little is known about the differential relationships between children from families who experience different levels of housing risks (e.g., Suglia et al., 2011). In addition, early childhood care centers, such as Head Start, also have been linked to children’s as pre-literacy skills and social-emotional functioning. Factors within Head Start, such as classroom quality, serve to buffer risk associated with poverty for certain sub-sets of the population (e.g., Burchinal et al., 2000). Yet, no studies have sought to expand the Family Stress Model to include factors within Head Start that might intervene or buffer the pathways related to parenting for families who experience housing stressors for children who face housing risks. The present study examined the relations between parental depression symptomology, parenting practices, classroom quality, and children’s functioning during the pre-kindergarten Head Start year in a national sample of children who attended Head Start between 2009- 2012. 117 One goal of the present study was to consider whether classroom quality can buffer parenting practices in the indirect relation between parental depression and children’s functioning through parenting practices for the full pre-kindergarten sample. However, the primary aim of the study was to consider the differential relations in the full model during the pre-kindergarten year between children who experienced housing instability during Head Start in comparison to those who were stably housed throughout Head Start. This study is the first known empirical examination to use multi-group structural equation modeling techniques to consider differential relations between unstably housed and stably housed children. Specifically, the study contributes to the literature on two widely studied theories: Family Stress Model and Risk/Resilience with a novel sample. In addition, the study is a unique contribution to the broader literature because of the focus on understanding the complex relations between multiple social context variables in the consideration of children’s prekindergarten functioning more broadly. Full Sample Pre-Kindergarten Year Findings The hypothesized model on the full sample was partially supported. However, evidence of moderated-mediation was not supported. Classroom quality did not moderate the indirect relation between parental depression and children’s functioning through parenting practices. Furthermore, contrary to studies that have shown that preschool classroom quality is related to early academic functioning, the latent construct of classroom quality was not significantly related to latent constructs of children’s social-emotional or academic functioning in the present study at the end of the pre-kindergarten year (Mashburn et al., 2008; Pianta et al., 2005). A plausible explanation for these results may be that the cross-sectional design of the study may not have captured the underlying role of classroom quality, which may be masked until later years. 118 Although research suggests gains associated with Head Start and pre-school are immediate, some literature highlights long-term benefits into childhood and adolescence (Barnett & Hustedt, 2005; Puma et al., 2005). This literature would suggest that it could be plausible that among all children who attended Head Start, the role of various types of classroom environments were similar for most children immediately following the pre-kindergarten year, however children who were placed in higher quality classrooms during Head Start may exhibit more pronounced differences throughout childhood and later in their schooling. Therefore, although research has shown that outcomes associated with Head Start are typically present immediately following Head Start, some of the benefits associated with quality early childhood care may be masked until later in children’s developmental trajectory (Barnett & Hustedt, 2005; Ludwig & Miller, 1997). As predicted, based on the Family Stress Theory, parental approaches partially mediated the relation between parental depression and children’s pre-kindergarten social-emotional functioning and language and literacy functioning. Depression negatively predicted parental approaches, which in turn was positively related to latent constructs of children’s prekindergarten social-emotional functioning and language and literacy functioning. These results suggested that the influence of parental depression is partially observed through parenting practices, specifically those reflective of approaches to parenting (e.g., warm interactions, harsh parenting). This relationship was in the expected direction and supports previous research that has examined this theory in populations faced with economic stressors (Conger et al., 2002; Riley et al., 2014). These results underscore the importance of high quality, salient mental health and parenting supports for families facing sources of economic stress. 119 A few relations that emerged were, however, in the unexpected direction. First, in the partial mediation of depression on children’s functioning through parenting, the direct association between parental depression and the latent construct of language and literacy was in the positive direction, suggesting that increases in endorsement of depression symptomology were positively related to increase in children’s language and literacy skills. Similarly, parental depression demonstrated a small, but significant positive association with parental engagement, leading to a marginally significant, small mediation on social-emotional outcomes. Although the standardized effects were small (.08), these relationships are contrary to previous research that has suggested negative relations between parent depression and parenting behaviors, as well as children’s language skills (e.g., Goodman et al., 2011). A few explanations may possibly explain these unexpected relations. First, the depression measure was skewed in the positive direction, with the average score among the full sample reflecting mild symptomology (M=4.06). This indicated that depression symptomology in the full sample was relatively low and a sample that exhibited greater variation may more accurately detect expected relations. The lack of expected relations should be interpreted cautiously. However, it is unclear as to why then the CES-D scores were sensitive enough to show expected patterns between depression and parental approaches. Second, the measurement of the construct of engagement may offer some insight into the positive association between depression and parental engagement. Though from the broader literature, indicators that comprised this construct which included parental behaviors such as taking a child on an outing or reading to a child, may have been less reflective of the types of parent-child interactions that occur during such activities (e.g., open-ended questioning). Therefore, parents who did endorse depression symptomology may have still participated in parent-child activities, as well as literacy practices within the home 120 that could have been related to standardized assessment scores; perhaps even more readily in this sample, given that Head Start aims to increase such opportunities for families. Yet, the types of interactions with the child during the activity were not measured. Third, parental engagement items demonstrated borderline levels of reliability in the present study, despite being drawn from previous national studies and validated measures (e.g., HOME), which may suggest such items were not a full representation of the construct of parental engagement. Group Differences by Housing Risk The primary aim of the study was to consider differences in the hypothesized model between children who experienced housing instability during Head Start and those who were stably housed throughout. Both mean level differences in parent depression, parenting, and children’s pre-kindergarten functioning, as well as differential relations between parental depression, parenting, classroom quality, and children’s functioning were examined through MG-SEM, while controlling for economic risk and child gender. MG-SEM techniques provided a sense of whether differences across nested models were statistically significant, such that a grouping variable (e.g., housing status) moderated different pathways within the model. Taken together, few significant differences emerged between stably housed and unstably housed children in MG-SEM models when accounting for economic risk levels and child’s gender. With the exception of mean level differences on the latent construct of parent engagement, no additional differences were found. However, despite a lack of true moderation indicated by MG-SEM models, initial testing of the model revealed interesting potential sources of difference across groups that are discussed in further detail below. All findings should be interpreted in light of the lack of heterogeneity across the sample. The sample was comprised of a national sample of Head Start children, of which a large 121 percentage of the children faced economic risk factors (e.g., low maternal education, low family income) indicative of poverty. For this reason, fewer differences may have emerged between stably housed and unstably housed children and families. Nonetheless, the findings do suggest that although few differences emerged, there may be unique reasons to consider housing risks as a similar, but a differential context than other economic risks that are characteristic of poverty. The absence of differences between groups may also be related to the contributions of Head Start in mitigating risk for children who faced with housing risks. Specifically, the Head Start effectiveness research (e.g., Head Start Impact Study) provides evidence for short-term and immediate gains in areas of pre-literacy and social-emotional functioning (Puma et al., 2005; Welsch et al., 2010). Given the well documented shorter-term gains associated with Head Start, it is reasonable to suspect that enrollment in Head Start alone may increase parental and child skills to a degree. Therefore, null results across groups within a sample of Head Start children may, in fact, suggest that exposure to Head Start during early childhood may buffer the risks associated with housing instability. This is an area that warrants future research with a more rigorous design that includes a comparison group of children facing housing risk and not enrolled in Head Start programming. Differences in Levels of Parenting and Child Outcomes MG-SEM revealed a mean difference in the latent construct of parent engagement. Specifically, this difference translated to a large standardized difference (.91), which suggested that parents of children who were unstably housed engaged in lower levels of engagement. This finding is consistent with previous studies that have found that economic risks and housing instability, specifically, may pose barriers for families to engage in children’s schooling and learning-related activities (Jozefowicz-Simbeni & Isreal, 2006; Koblinsky et al., 1997). Yet, this 122 finding may be not fully capture the nuances of parent engagement, as other studies, particularly qualitative in nature, have indicated that parents who face housing instability may utilize more context-specific sources to parenting (MacGillvery et al., 2009). The present findings indicate that parents of children attending in Head Start may face barriers to accessing involvement in learning and schooling in forms historically characteristic of Head Start and other pre-school programs. No additional mean level differences emerged in the MG-SEM between unstably housed and stably housed families or children with regards to parent depression symptoms, parental approaches, social-emotional functioning or academic skills. These findings suggest similar pre-kindergarten levels of child and family functioning among families who experienced housing instability and stably housed families. The results that compared mean levels of functioning between unstably housed and stably housed families are a particularly salient contribution to the literature due to the scarcity of studies that allow for group comparisons due to sample size limitations. Furthermore, this is the first known study to consider pre-kindergarten levels of functioning among children who experienced housing instability during Head Start, despite the relevance of this developmental period to long-term academic and social-emotional functioning and the potential for elevated risk associated with housing instability during early childhood (Fowler et al., 2014; Rumbold et al., 2012). The findings implied that among Head Start children, children who experienced housing instability at least one time point in pre-school may enter kindergarten with comparable socialemotional and academic skills to those who were stably housed throughout Head Start. Furthermore, when accounting for economic risk and gender, parents of children who were unstably housed reported comparable levels of depression and employed similar approaches to parenting, but were less engaged in schooling and learning-related activities. Although these 123 mean differences were not seen across univariate tests on indicators of parent engagement individually, the use of latent variables allowed for the detection of these differences by representing a common underlying broader construct. Differential Relations MG-SEM revealed no differential pathways between children who experienced housing instability at least once during Head Start and those who were stably housed throughout. The lack of differential relations held across direct, indirect, and moderated-mediation pathways, such that there were non-significant differences in the relations that involved the mediators (parent engagement and parent approaches) and moderated-mediation (classroom quality and parenting) interactions. In other words, results suggested a similar pattern of relations, such that none of the relations included in the model were significantly different based upon housing status. These finding imply that housing status may not moderate the hypothesized model tested in the present study. Contrary to hypothesized relations, the results imply that housing status functions similarly to other economic risks, evidenced by the lack of differences found across Head Start children. This further indicates that similar outcomes may be expected across children who face housing instability during pre-school and those who face economic risk, but are stably housed. Although it is truly possible that housing instability is not a differential context of risk, apart from poverty risks, other explanations may also be likely. Despite the larger sample size for a high-risk population serving as a primary strength of the study, detection of mediation and moderated-mediation relations require large samples. Therefore, it is also possible that the sample size for unstably housed group did not provide ample power to detect complex, nuanced differences of interest to the present study. In addition, the study utilized a broad 124 conceptualization of housing instability that included both families living in various types of housing conditions and those who experienced frequent moves in a short period of time. Although this definition is consistent with the approach used by many studies, other studies have considered differences at the sub-group level (e.g., sheltered families, doubled-up) among those who do experience housing risks (e.g., Gewirtz et al., 2009; Narayan et al., 2012). Furthermore, if the sample and available measures had allowed for a more concurrent examination of housing status, parenting, and child outcomes, the study may have produced differing results. Despite not approaching significance as true moderation by housing status in multi-group models, an initial examination of the model for each group separately prior to MG-SEM analyses revealed one noteworthy difference. The direct path between classroom quality and children’s pre-kindergarten behavior was significant for children who were unstably housed (β = .27, p<.05), whereas this path was non-significant for children who were stably housed. Although this differential relation may have been marginal and not large enough to be captured by MGSEM models, the findings may suggest that it could be possible that classroom quality may have a slightly more pronounced influence for children who face housing risks. Such a finding is in line with research has found that children facing certain risks may benefit to a greater extent from high quality classrooms (Burchinal et al., 2006; Vallotton et al., 2013). However, there are several reasons this relation may not have emerged in MG-SEM models. It is possible that factors within the social context, such as classroom quality have more pronounced effects for smaller sub-groups within the broader sample of unstably housed children. Due to the inclusion of a broad range of housing conditions in the present study, this relation might not have been detected clearly in the MG-SEM models. Furthermore, another explanation may include the consideration of background characteristics that may interact with 125 the social context in mitigating risk. In the studies by Burchinal and colleagues (2000;2006), classroom quality was most pronounced for African American children facing economic risks on indicators of language functioning, indicating that the consideration of multiple background characteristics, such as both race and housing status or gender and housing status could reveal differential relations. This type of approach is also in line with literature that emphasizes the concept of intersectionality, or the multiple aspects of identity that shape individual experiences and is further discussed regarding the post-hoc analyses (Cole, 2009). Race and Housing Status Although not a primary aim of the study, exploratory post-hoc analyses considered measurement invariance by maternal race due to the significant degradations in model fit with race in the model, as well as and the relations between housing status and maternal race. The inclusion of these exploratory analyses was important given the relationship between economic stress and the historical context of housing instability in the United States (Cohen & Wardrip, 2011; Massey & Denton, 1993). Results of these analyses appeared to suggest variance by maternal race with regards the measurement model, indicating that although maternal race may by structurally relevant to the model, these relations may not have been measured similarly across racial groups. Although out of scope within the present study and not explored further, the exploratory results suggested intercept invariance. As discussed by Keith (2014), intercept invariance typically signifies differential scaling of the indicators (e.g., starting points), relevance of specific factors (differential item functioning), and/or bias related to constructs across groups. Specific reason for these differences were not further explored in the present study. Exploratory follow-up analyses that focused on univariate relations between race, housing, and indicators of latent constructs were conducted. A particularly noteworthy area for 126 future exploration may be the interaction between race and housing status with regards to teacher rated problem behavior, in which these results indicated a trend towards teachers rating children of African American/Black mothers who also experienced housing instability as exhibiting higher problem behaviors. Again, despite reaching beyond the scope of the present study, these findings partially align with the literature that has suggested heightened perceptions of externalizing behaviors of Black students in the classroom, even as young as pre-school (e.g., Graves & Howes, 2011; Mashburn et al., 2006). Scholars have interpreted such findings as a possible result of mismatch of expectations between families and schools or racial bias, but have also noted the importance of other context variables in producing differential experiences, such as racial identities of the broader school population and teacher-student relationships (Graves & Howes, 2011; Skiba & Williams, 2014). Nonetheless, the central relevance of these results to the present study is the salience of considering more complex, differential patterns based on the both housing and race. Although exploratory, these results highlight the importance of the inclusion of intersectional analyses that consider context at the level of housing status and multiple background factors that are related to child outcomes and family functioning as a future direction. Clinical and Practical Implications The present study has several strengths and implications for the areas of early childhood education, prevention, and intervention. A primary implication of the present study is the importance of continual screening for specific types of risk throughout pre-school and childhood. Although programs such as Head Start already target high-risk children, the present study provides some insight into ways children and families who face housing risks in particular may differ from the general Head Start population. The importance of continual screening by early 127 childhood care centers and schools would allow programs to link families with appropriate resources and interventions for given developmental periods. Implications of this particular study are such that families who face housing risks when their children are in pre-school may also face greater barriers to typical forms of school and home-based engagement at kindergarten entry, and thus, working with families to consider either alternative methods of engagement (e.g., identifying community resources, such as libraries) as identified by existing and future research or reducing barriers for families (e.g., transportation) may increase the frequency of positive parent-child activities (Koblinsky et al., 1997; MacGillivery et al., 2009). The findings also have implications for improving the broader social context of children who face poverty and housing risks. First, the findings highlight that relevance of parenting interventions for children who live in poverty and face related risk factors. Although the magnitude of the relation did not differ by housing status, approaches to parenting served as a mediator in the relation between parental depression and children’s outcomes, particularly socialemotional functioning across both groups. This is a finding that has consistently held across both children faced with poverty risks during early childhood more broadly and indicates the importance of support for positive parenting practices during sensitive developmental periods (Conger et al., 2002; Riley et al., 2014). This study specifically suggests that the prekindergarten year is a developmental period in which parenting approaches play an important role. Clinically, this may translate as accessible, coordinated behavioral health interventions, such as parent training programs and parental psychotherapy related to the context of poverty. Given the nature of the Head Start sample, drawing from work on the adaptations of evidencebased mental health interventions (e.g., Incredible Years), the findings also imply that the 128 incorporation and acknowledgement of psycho-social impact of contextual stressors of poverty within evidence-based behavioral health initiatives with low-income families to deliver more contextually salient interventions. Working with families to ensure that intervention recommendations are relevant and feasible for families based on their contextual situations (e.g., housing instability) may be most effective. In addition to parental supports, a noteworthy implication of the present study is the relevance of early childhood social-emotional functioning. In addition to pre-latent variable differences, the strongest overall relations emerged with respect to child social-emotional functioning, particularly with regards to parental depression and parenting approaches both in the full sample and sub-samples based on housing risks. This is consistent with literature that suggests that the pre-school years appear to be an important time point for early social-emotional development (Fowler et al., 2014; Rumbold et al., 2012). Therefore, the results largely lend support to the literature on universal social-emotional interventions integrated into Head Start programming. Integration of key skills measured by latent constructs, such as pro-social skills, coping, and emotion recognition/regulation may be important pre-kindergarten skills to target for the broader Head Start population, particularly for those facing greater threats in the form of contextual risks, such as poverty and parental depression that can jeopardize parenting practices within the home. Additionally, the findings of the present study also implicate the possibility of differential relations of quality within the classroom. Although classroom quality played a minimal role in the overall model and was not a moderator in the mediated pathways that involved parenting, the analysis of separate models by group membership indicated that classroom quality may have a significant influence on social-emotional functioning for children who face housing risks. Yet, 129 this difference was not indicated in the full multi-group model. These findings may suggest although parenting may be the more salient with regards to social context influences during the pre-kindergarten year, classroom quality may play a greater role for a sub-population of children who may face housing risks. Although further research has yet to confirm the role of classroom quality and the present study suggests a minimal, largely non-significant role of classroom quality, these preliminary findings may indicate that program-level investment in improving Head Start classroom quality could benefit children facing certain housing risks to a greater degree. The present study also suggests the importance of considering housing instability in conjunction with other background characteristics of the child and family. In the present study, race, along with housing, emerged as a salient factor in post-hoc analyses, particularly with respect to child social-emotional functioning in the classroom. In particular, the finding that teacher rated behaviors were dependent upon and different for children in unstably and stably housed groups by race implies that child behavior may be perceived differently in the classroom as a product of multiple characteristics and background factors interact with housing status. In lieu of these findings, early childhood centers that emphasize cultural sensitivity training for staff around building school-family relations with families of varied backgrounds, coupled with supports for marginalized families of color noted earlier, may not only reduce the potential for bias in teacher perception of child behavior, but could also improve social functioning of the larger student population of the Head Start center. Limitations and Future Research Despite the many strengths of the present study, including a large sample and rigorous analytic procedures, there are several limitations and areas in which future research could focus. 130 First, future research may consider a longitudinal examination of the model included in the present study. Although a cross-sectional design was selected to focus on the end of the prekindergarten year, it is possible that the influences of classroom quality and parenting may exert themselves on academic and social-emotional functioning at later time points during schooling. Therefore, a longitudinal design that may more clearly demonstrate the trajectories expected for children who face housing instability during Head Start. More specifically, the use of other Head Start datasets, including the Head Start Impact study may allow for meaningful comparison of the developmental trajectories across unstable and stably housed children who did and did not attend Head Start. Furthermore, comparisons of the dosage of housing instability at multiple time points across the early childhood and early school-aged years may also be feasible with such datasets. For example, questions related to whether those who were unstably housed throughout Head Start fared worse into the early school-aged years compared to those who experienced instability at fewer time points may be addressed. Such an approach was not feasible in the present study due to the scope of the study and the lack of available measures of interest across all time points. Additionally, the use of secondary data imposes restrictions upon measurement and definition of constructs. The nature of secondary analysis not only constrains the measures and approaches used, but also removes the researcher from experiencing the challenges of data collection and possible sources of error associated with sampling when interpreting results. Although the dataset selected for use in the present study included accepted indicators of the constructs of interest, there were both issues related to measurement (e.g., reliability) and/or the potential for alternative forms of measurements of the constructs. 131 First, there were several measurement issues introduced with available measures. Many of the measures used in the present study were the combination of several standardized measures, which may have restricted the constructs intended to be measured by the original scales. Moreover, F.A.C.E.S developers noted slight alterations to the standardized language and literacy measures to balance large scale data collection with standardization (Malone et al., 2013) Additionally, the use of secondary data limited the measurement of the constructs to some measures with borderline low or moderate levels of reliability (e.g., parenting measures). Issues related to measurement of indicators may have introduced more error in latent variables and may not have fully captured the construct of interest. Future research that includes standardized measures with a wider range of items to capture desired parenting and social-emotional concepts would contribute further to the literature. In addition, alternative forms of measurement may be useful to some study constructs. Specific to parenting practices, while one of the intended goals of the study was to better understand parenting practices within the context of house instability, the measures involved approaches to parenting from a largely middle class notion of parenting. It may have also been likely that the modality, phone interviews, used to collect sensitive information related to depression symptoms may have resulted in response biases on depression or parenting measures. Therefore, alternative measures or methodologies, such as qualitative or observational approaches, may better capture the rich variation that likely exists across families facing housing instability. Also related to measurement, there are some challenges with the conceptualization of housing instability. Due to the available items to represent housing instability and to maximize the sample size, the present study used a widely accepted definition of housing instability from 132 the broader literature that included those who moved frequently in a short period of time and those who lived in uncertain housing situations at any point during Head Start (e.g., homeless, doubled-up). However, there may be variation among the sub-groups that wasn’t captured as a result of grouping several forms of housing instability together. Although the present study did not allow for analysis by housing sub-groups, future research could include one or more of the groups to consider more differences at the housing sub-group levels. Furthermore, families were included in the unstably housed group if they met criteria at any point in time during Head Start. The rationale for this approach was to maximize sample size, capture transiency throughout Head Start, and consider the pre-kindergarten functioning of those who experienced instability throughout Head Start. Yet, it is likely that some families were not represented due to losing housing for a shorter period of time between data collection time points. Although a strength of the approach used in the study is that it included a broad group of families who are likely to experience housing instability, it could also have masked immediate effects of instability on parenting or children’s outcomes not explored in the study. Additionally, this conceptualization of housing instability did not capture the potential role of the length of exposure, nor whether more cumulative housing risk may differentially relate to outcomes, Future research that continues to consider ways to conceptualize housing differences among families would be a valuable contribution to the literature. Another consideration is the limitations in the analytic approaches used in the present study. Although SEM and use of latent variables allowed for complex modeling and a novel approach to consider outcomes between children who experienced differing housing conditions, there were limitations that were associated with the approaches used. One of the greatest statistical challenges that arose throughout the study was accounting for latent variable 133 interactions in SEM models, which posed difficulties with assessing model fit. Furthermore, several changes to the model were initiated as a result of statistical challenges, rendering the findings exploratory. Some of these changes included alterations to the measurement model and dropping race as a covariate from the structural base model due to poorer model fit with the unstably housed group, calling into question the stability of the parameter estimates. Such changes were made to proceed with analyses and answer the central research questions, however do require replication by future studies to confirm the findings and thus should be considered exploratory. Moreover, despite the large sample size for an understudied population, a simulation study (e.g., Monte Carlo simulation) would be required to truly determine the necessary sub-samples to determine adequate power. While such challenges are inherent within SEM studies, it is important for future research to continue to consider alternative analytic approaches to similar questions to reduce statistical error and consider novel methods to examine outcomes associated with housing instability during early childhood, including both quantitative and qualitative methodologies. Despite the inclusion of a wide range of constructs, another area of measurement that served as a limitation is the missing data. Even after weighting to adjust for sampling and attrition in the broader dataset, language measures were incomplete due to F.A.C.E.S sampling and language routing procedures. This level of missing information can bias conclusions drawn about the language and literacy construct. Furthermore, general attrition in large scale surveys is problematic and may be a less valid national representation of the Head Start sample. A final area of development for future consideration is theoretical, particularly in expanding the Family Stress Model. Findings from the present study provided support for this model, yet also delineated the relevance of considering the ways in which other environmental 134 factors, such as classroom or Head Start level factors, interact with parenting. Additionally, background characteristics of the child or family (e.g., race) may have a differential influence based on housing conditions. Future research that expands and integrates the Family Stress Model with models that account for context, such as Risk and Resilience or Ecological Systems Theory would provide greater insight into the ways in which specific conditions of poverty (e.g., housing instability) collectively function. Conclusion The present study examined the differential relations between parental depression, parenting, classroom quality, and children’s pre-kindergarten functioning across Head Start children who were stably housed and those who experienced housing instability at least one-time point during Head Start. The study specifically attempted to expand a more established indirect relation that parenting practices partially explain the relation between parental depression and child functioning by considering if classroom quality may mitigate risk differentially by housing status during the pre-kindergarten year of Head Start. The results somewhat supported the previously established indirect relations in which approaches to parenting, but not parent engagement, partially explained the relation between parental depression and children’s functioning across children who were stably housed and unstably housed. However, classroom quality did not further exert a differential influence on parenting. Furthermore, few significant group differences emerged between the two groups, with the exception of differential mean levels of parent engagement practices. Although classroom quality did significantly predict children’s behavior for the unstably housed group, but not the stably housed group, this finding did not emerge as significant in the final model. The study suggests that the influence of housing instability may function similarly to other forms of 135 poverty, but also indicates some areas of difference between the two groups. Therefore, future directions of this work that include continued exploration of additional factors within Head Start or the classroom that mitigate housing related risks would continue to expand this avenue of research, as well as distinguish potential sources of prevention and intervention to buffer housing related risks. Although the study was largely focused on housing instability as a developmental context of risk, the post-hoc analyses further suggested reason for future work to explore the potential interactive influences of both housing and other background characteristics (e.g., race) in better understanding the influences of housing instability on child and family functioning. These results suggested a potentially dependent influence of race and housing for teacher behavior ratings, such that African American children who experienced housing instability were also rated as exhibiting the highest level of classroom behaviors. This exploratory finding warrants future consideration and highlights the importance of a more intersectional approaches that attempt to integrate multiple aspects of the family background in understanding child and family functioning to ultimately provide more culturally salient services. Overall, the present study highlights the importance of considering the potential for housing instability as a context of risk, in conjunction with other poverty related risks, during the pre-kindergarten year or prior to kindergarten entry. The findings specifically suggest that levels of parental engagement may differ for children who experience housing instability as opposed to those who remain stably housed. Furthermore, there may be differences between children who experience housing risks and those who are stably housed as a function of race or culture. Despite the modest findings, the present study is a valuable contribution to the broader literature because it is the first known examination that employed SEM techniques and considered 136 interactive influences of the social context for children who experienced housing instability during early childhood. Furthermore, the study expanded our understanding of the connection between home-based factors, including both parental depression and parenting practices, and child functioning. Findings from the present study also provide important future directions for better understanding the role of housing instability prior to kindergarten entry to promote functioning of an understudied group of children. 137 APPENDIX 138 APPENDIX Satorra-Bentler Chi Square Formulas Formulas publicly available at: https://www.statmodel.com/chidiff.shtml 1. cd= (d0 * c0 – d1*c1)/(d0-d1) cd= difference testing scaling correction factor d0= degrees of freedom in nested (or more restrictive) model c0= scaling correction factor of nested model d1= degrees of freedom in model to be compared c1= scaling correction factor of model to be compared 2.
