The sample included 4,168 male inmates nested within 185 state correctional facilities. The results suggest a complex relationship between remunerative controls and inmate assault. Remunerative controls were not significant predictors of inmate- on—inmate assault; however, prisoners involved in work programs were significantly less likely to assault staff, net of control variables. A significant relationship was not found between coercive control and inmate assault.

Researchers have sought to answer this question for over a half—century and three :models have emerged; deprivation, importation, and administrative-control. Traditionally, researchers have focused on the importation and deprivation models; however, recent studies have included variables under the heading of “administrative-control.” The deprivation model posits that inmate behavior (e.g. misconduct) is a product of the prison environment (Clemmer, 1938; Sykes, 1958). The importation perspective asserts that an inmate's pre-prison socialization is important and influences the inmate social structure and inmate adaptation. to the jprison environment (Irwin, 1980; Irwin and Cressey, 1962). Administrative-control theory departs from the deprivation and importation perspectives and posits that prison management is an important determinant of inmate misconduct (DiIulio, 1987). Administrative-control theorists have concentrated their attention on management's use of various control mechanisms, including discipline and programming to curb inmate misconduct. While numerous studies have assessed the validity of the importation and deprivation models, few researchers have tested the hypotheses deduced from the administrative-control model. The goal of this study is to provide such an‘assessment while controlling for the variables traditionally found under the importation and deprivation headings. Inmate assaults on staff and inmates will be used as the outcome measures. The analysis will use a subset of the 1991 Survey of Inmates of State Correctional Facilities (U.S. Department of Justice, 1993). Review of the Literature Traditional Models The deprivation model rests on the assumption that inmate behavior is a function of the prison environment. Donald Clemmer (1938), a pioneer in the field of prison research, argued that inmates assimilate into an inmate social structure and culture that condones deviant behavior. Gresham Sykes (1958), whose work provided an extension of Clemmer's ideas argued that there are certain “pains of imprisonment" inherent in prison, and these pains define social group formation and behavior within prison society. Pains of imprisonment include loss of liberty, loss of material possessions, and lack of autonomy (Sykes, 1958). Early studies of the deprivation model were based primarily on examinations of inmate coping’ mechanisms (Flanagan, 1980; Garabedian, 1963; Wheeler, 1961). Contemporary researchers have focused on examination of absolute deprivation. Absolute deprivation refers to the fixed institutional environment and has been tested in relation to overcrowding, custody level, time outside of cell, visiting patterns, and size of facility (Cao, Zhao and VanDine, 1997; Ellis, Grasmick and Gilman, 1974; Goetting and Howsen, 1986; Ruback and Carr, 1993). Of the absolute deprivation variables, prison crowding has been tested extensively; however, the direct relationship between absolute deprivation and misconduct is not clear (see Ellis, 1984). Importation theorists challenged the deprivation model and proposed an alternative model based on pre-institutional characteristics, culture, and environment (Irwin and Cressy, 1962) . Irwin (1980) argued that inmates did not enter prison tabula rasa, instead inmates bring roles and cultural expectations into prison. Pre-prison experiences and socialization also influences how one copes and forms social groups in prison (Irwin, 1980). The importation perspective has also been extended to include the effects of macro-social events and movements on behavior (Jacobs, 1977). Tests of the importation perspective have provided mixed results. Importation theorists have tested demographic variables such as age, gender, military involvement, prior arrests, employment, and marital status as predictors of misconduct (Cao et al., 1997; Ellis et al., 1974; Thomas, 1977). Importation theorists have also argued that inmate behaviors are a result of cultural histories and traits (Akers, Hayner and Gruninger, 1977; Harer and Steffensmeier, 1996). Harer and Steffensmeier (1996) verified the “subculture of violence” thesis by establishing a significant relationship between race and type of prison misconduct. Black inmates were more likely to engage in violent behavior and whites were more likely to engage in misconduct related to alcohol and drugs (Harer and Steffensmeier, 1996). These findings mirror misconduct rates typically found for these groups in the general population (Wallace and Bachman, 1991; Williams and Flewelling, 1988). Other studies have found little evidence supporting the importation perspective (Gaes and McGuire, 1985; Light, 1990). Both the importation and deprivation perspectives have made significant contributions to the study of prison misconduct. An integrated model has also been used to predict inmate behaviors and attitudes (Akers et al., 1977; Goetting and Howsen, 1986; Thomas, 1977). Although traditional models have been moderately successful in predicting inmate misconduct, there are limitations associated with both the importation and deprivation models. The importation. perspective has focused. solely’ on individual characteristics, but individual-level research does not provide guidance for prison managers in preventing prison misconduct when managers rarely have control of the type of inmates they house (McCorkle, Miethe and Drass, 1995:321). The deprivation perspective includes both organizational and individual determinants of prison misconduct; however, the deprivation perspective ignores the role of management in mediating or exacerbating levels of deprivation. The goal of this paper is not to discount the validity of the traditional models of prison misconduct. Because multi-level models are being tested, it is inevitable that specific theories within the deprivation and importation models will be tested (e.g., subculture of violence). However, the primary goal of this study is to examine what role administrative-control variables play in predicting prison misconduct while controlling for traditional variables. Administrative-Control Contemporary administrative—control scholars argue that the deprivation and importation. models have ignored an important element of prison misconduct and contend that “administration" should be included as a determinant of inmate misconduct. DiIulio (1987) studied three state prison systems: Texas, California, and Michigan. From his studies, DiIulio (1987) argued that prisons managed within a formal organizational structure with a strict division of labor, detailed rules and routines, and a consummate leader at the top of the organization will have significantly less prison disorder. Useem and Kimball (1989) also contend that control is an essential element of prison. management; however, they argue that the relationship between control and misconduct is more complex and that “administrative breakdown” is the cause of collective misconduct. Administrative breakdown occurs when the organizational structure of the prison erodes or is otherwise weakened, security measures are reduced, prison conditions and services deteriorate, and inmate deprivation increases above tolerable levels (Useem and Kimball, 1989). Collective prison misconduct is a result of gradual organizational breakdown (see also Useem, Camp and Camp, 1996). Administrative-control theory rests on the assumption that control is a necessary element in corrections management; however, there has been little consensus on the most appropriate type of control (DiIulio, 1987; Reisig, 1998; Useem and Kimball, 1989). Two specific forms of control have been advanced. Coercive control rests on the threat or application of physical sanctions, the generation of frustration through control, or restriction on achievement of personal needs through force. Remunerative control is based on the allocation of material resources and rewards (Etzioni, 1961:8-22). Remunerative controls function as incentives in organizations and engender commitment to cuganizational rules and goals; whereas, coercive controls frustrate and alienate organizational members (Colvin, 1992; Etzioni, 1964). Research guided by the administrative- control model has confirmed the importance of incentives. Correctional institutions that maintained a balance between coercive and remunerative controls were less likely to have high incidence of misconduct when compared to institutions that used coercion as the sole means of control (Colvin, 1992; Reisig, 1998; Wright 1994). Research on the relationship between prison programming and inmate behavior has been widespread. The majority of researchers have focused their research on prison programming as a predictor of recidivism (e.g. Matthews and Pitts, 1998; Turner and Petersilia, 1996). Researchers have also centered evaluations on specific types of programming such as HIV education, anger management, or residential drug treatment (Accordino and Guerney, 1998; Eisenberg and Fabelo, 1996; Harrison et al., 1998; Matthews and Pitts; 1998). This body of literature has provided contradictory evidence on the effects of prison programming on post-incarceration behavior (Eisenberg and Fabelo, 1996; Inciardi et al., 1997; Ward and Baldwin, 1997). Few researchers have examined the effects of prison programming on institutional behavior. Research conducted in this area has indicated that inmates involved in educational and vocational programming or work are less likely to assault prison staff or inmates (Gaes and McGuire, 1985; McCorkle et al., 1995). Research Objectives Due to the adolescence of the administrative-control model, the perspective has not been subject to rigorous empirical assessment. Existing studies of administrative-control have been limited by two factors. First, the majority of research conducted within this perspective has been qualitative and based on case studies (DiIulio, 1987; Useem and Kimball, 1989; Useem et al., 1996). Second, the scope of the current work has been very limited. Many studies have also been based on only a small sample of correctional facilities (e.g., Reisig, 1998). Specifically, studies have not been performed to ascertain the relationship between specific control (i.e., solitary confinement) and incentive (i.e., work programs) measures on prison misconduct. This study hopes to help fill this void left in the administrative-control literature. This study has been designed to overcome many of the limitations associated with previous studies within the administrative-control model. Unlike other studies performed, this study will use a nation-wide sample of inmates to assess simultaneously the effects of administrative-control variables on prison misconduct, while controlling for traditional variables such as age, race, and criminal history. Methods and Data Sampling This study used a subset of the data provided in the 1991 Survey of Inmates of State Correctional Facilities (U.S. Department of Justice, 1993). The sample data includes information collected through personal interviews from 13,986 inmates within 272 state correctional facilities during June, July, and August 1991. Using a two-stage selection design, the sample was selected from 1,239 institutions with 613,894 male and 34,538 female inmates. The first sampling stage included selecting institutions tn! population, census region, facility' type, and security level. A systematic sample was then selected from each sampling frame based on probabilities proportional to the size of the prison. In the second stage, a systematic sample of inmates was taken from each prison based on the daily roster of inmates. Nine hundred inmates refused or were unable to be interviewed resulting in a sample of 13,986 inmates. The overall non- interview rate was 6%. .All inmates housed in community or “unclassified” prisons were also deleted from the sample. Using listwise deletion, a subset of data was selected consisting of 13,370 male and female inmates nested within 247 correctional facilities. A representative subset of the initial data set was then selected from inmates with complete dependent variable information and included 5,026 inmates and 224 puisons. Women were then deleted from the data-set resulting in a final sample of 4,168 male inmates nested within 185 state correctional institutions. Prison-level data were constructed by aggregating individual inmate data by institution. It can be assumed that the individual inmate data are representative by prison because of the detailed sample design employed by the U.S. Department of Justice (1993). Inmates interviewed at each of the prisons selected were assumed to be representative of that prisons total population. Representativeness was assured (due to the complex weighting and stratified sampling technique employed by the Bureau of Justice Statistics. Dependent Variables Two dependent measures of inmate assault will be included in the analysis. For each of the measures the inmate was asked, “since your admission, how many times have you been found guilty of”, (1) physical assault on staff or (2) physical assault on inmate. Prior studies have relied only on dichotomous dependant variables (e.g., Light, 1990). Count data is preferred to categorical data because it allows the researcher to model how many offenses will occur opposed to simply if misconduct occurs (Gardner et al., 1995). / / Contextual Variables Three remunerative variables will be included as contextual variables. The remunerative control variables are designed to measure positive incentives provided by prison administration. All remunerative control variables represent the percentage of the prison population that have received remunerative controls at some point during their current incarceration period. Remunerative control measures include percent of inmates that work outside the prison facility, work inside the prison and have a paid work assignment. Two coercive control variables will be included as contextual variables to measure institutional punishments. A [I 1:. I? u hwtcoerc1ve control scale was constructed to measure loss of work or ‘d f general privileges as a result of prison misconduct. The factor included two measures: Percent of total inmate population that (1) lost a work assignment or (2) lost general privileges as a response to the most recent rule infraction (eigenvalue = 1.32; factor loadings >0.70). A measure of solitary confinement will also be included as a contextual variable. The solitary confinement variable represents the percent of the total inmate population that received solitary confinement as ea disciplinary response to the most recent rule infraction. 10 Independent Variables This study includes several measures of individual inmate attributes. These variables represent individual pre-prison characteristics and will be used as control variables. Descriptions of all variables are provided in Appendix A and descriptive statistics are included in Appendix B. Three dummy coded measures of race were included: white, African American, or other (Asian, Pacific Islander, Eskimo, or other). A separate dummy measure of Hispanic ethnicity was also included. Citizenship was also dichotomized into citizen (reference category) and non-citizen. Age was included as measured as the inmate's age in years (mean = 30.51; S.D. = 8.15) . Marital status was dichotomized into married (reference category) and not married. A measure of length of incarceration was included and calculated based on number of years inmate had served for their current sentence at the time of data collection (mean = 2.81; S.D. = 2.56) . Two scales were included as control measures. Gang membership is an additive scale constructed using four survey items: “Did you ever belong to a group that” (1) had members from the same area, (2) have a turf or territory, (3) have a formal membership, and (4) have a known leader? (Cronbach's alpha = 0.79). A four—item factor score was also developed to measure criminal history. The factor score included four items: total sentence in years, currently serving for a violent crime, age at first arrest, and number of prior arrests (eigenvalue = 1.19). 11 Prison—level Controls Three prison~level control variables were included. Census region and prison security levels were included as dummy— variables. Census region reflected whether prison was located in the South census region (reference category) or otherwise. Level of prison security was also dichotomized into Maximum security (reference category) and other security level. A measure of prison population was included as final prison count at the date of data collection (mean = 1503.04; S.D.= 1280.40). Analytic Technique Hierarchical linear modeling (HLM) was used as the primary analytic technique (Bryk and Raudenbush, 1992). HUM is the most appropriate technique for this analysis because it allows the individual inmate data to be nested within prisons while studying variation in incidence of inmate assault. HLM has many advantages over traditional multivariate models. Typically researchers were forced to choose between ignoring the multilevel nature of the data or by aggregating all individual—level data to the organizational level. These traditional modeling techniques increase validity concerns. Ignoring the natural clustering in data significantly increases the Type I error rate and aggregating individual-level data discards important within group variation (Kreft and De Ieeuw, 1998:10). HLM resolves many of the problems with multi—level modeling by allowing the researcher to model data within natural clustering, while simultaneously 12 modeling both within and between group variance. In conventional HLM methodology Ordinary Least Squares regression is used; however, OLS assumes that random errors are independent, normally distributed, and have constant variance (Bryk and Raudenbush, 1992:15). Because a majority of inmates have not committed an assault, the dependent variables are positively skewed. Significant overdispersion of time dependent variables violates the OLS assumptions. An overdispersed Poission model will be used instead of the default OLS model in this analysis to compensate for overdispersion. Overdispersed Possion models calculate a factor to correct the inferential statistics; therefore, statistical reliability is not compromised (Gardner et al., 1995). Four general models will be estimated for each dependent variable in this analysis. The One-way ANOVA model is the first model estimated. The ANOVA model provides an estimate of within and between prison-variance and a reliability estimate of the sample mean. The second model, the fixed effects model, attempts to measure variation in the dependent variable as a function of inmate-level variables. The intention here was to explore how inmate assault varies with. each, inmate-level predictor; The third model, the means as outcomes model, assesses which individual level slopes vary by mean prison incidence of assault. The inmate and jprison-level. models are then combined into a single hierarchical model. The final model evaluates the probability that individual incidents of assault vary as function of individual and contextual variables. 13 Results Preliminary Models Four models were constructed for each dependent measure to determine the relationship between individual and contextual variables on inmate assault. The modeling strategy used here is consistent with established HLM methodology (Bryk and Raudenbush, 1992). The One-way ANOVA model with random effects is the first model constructed. This variance component model is used as a baseline for future modeling and for the estimation of variance that lies between and within prisons (Kreft and De Leeuw, 1998:63). An intra-class correlation coefficient is also obtained from this model and illustrates the proportion of variance in level two units (e.g. prisons) (Kreft and De Leeuw, 1998). An ANOVA model was constructed for both the inmate and staff assault variables. The intra-class coefficient from staff assault was 0.33; therefore, 33% of the variance associated with assault on staff lies between prisons. At 12%, the intra-class coefficient for inmate assault was much lower than for staff assault. This model also produces a reliability estimate of the sample mean. The sample mean for staff assault is a moderately reliable measure (>.57) of the true mean of staff assault. The sample mean for inmate assault is also moderately reliable (>.49) measure of the true mean of inmate assault. The second model specified is the random coefficient model. 14 This .model tests if the relationship> between individual-level variables and inmate and staff assault varies across the population of prisons. In random coefficient models, slopes are allowed to vary by institution. If variance in the slopes is significantly different than zero, it is assumed that the variation in the individual-level slopes is a result of contextual effects (Kreft and De Leeuw, 1998:43). Each of the individual-level variables is centered around the group (prison) mean. Traditional Ordinary Least Squares regression was used in place of the Overdispersed Poisson model due to data limitations in the random coefficient models; however, the temporary change will not negatively effect further models. Two random- coefficient models were estimated, one for each dependant variable. The first random-coefficient model estimates the effect of individual-level variables on inmate assault. Gang membership and criminal history were the only variables found to vary significantly by institution. Together the group of inmate-level variables explains about 9% of total inmate-level variance. The effect of inmate-level variables (n1 staff assault was the second random-coefficient model estimated. The inclusion of the inmate-level variables explains about 5% of the inmate-level variance above the initial. model. Gang' membership, criminal history, and African American significantly varied by institution. The coefficients for age and education indicate a negative relationship between age, education and staff assault across prisons. 15 Table 1.

Because the individual- level variables are used as controls in the final models, there is little utility in modeling the variation in these variables between prisons. The third model is the fixed-effects model. This model is similar to the random-coefficient model; however, in this model individual variables are considered fixed. In the fixed-effects models, individual-level slopes are constrained to be constant across institutions (Table 1). Individual-level variables are modeled against an estimate of the average intercept and slope across all institutions. This model indicates that African American gang members with a high criminal history score are more likely to assault both inmates and staff. Educated and older inmates were found to be less likely to assault staff and inmates. Inmates of other races are more likely to assault inmates, but no relationship between other race and staff assault was found. Finally, a "means as outcomes" model was constructed. In this model (not shown), both the intercept and slope for inmate and staff are modeled as a function of the prison-level controls and remunerative and coercive control measures. To aid interpretation, each level-2 variable is centered around its grand mean. The addition. of prison-level controls improves the explanation of variation in inmate assault on inmate; however, the inclusion of remunerative and coercive controls adds little 17 to the model. Maximum security, south census region, and inmate population were all significant predictors of inmate assault. A significant relationship> between. the remunerative and. coercive control variables and inmate on inmate assault was not found. Remunerative controls add significantly to the assault on staff model; whereas, prison-level controls add little to the model. Maximum security was the only prison-level control variable that was a significant predictor of staff assault. “M‘fi Remunerative control measures were found to have a negative .....I __ . .c relationship to staff assault.

Contextual Models Building on the preliminary models, two full hierarchical models that include both contextual and individual-level variables were estimated. The first model tests the relationship between remunerative and coercive controls on prison assault, net of individual controls. The second model estimated the probability that individual incidents of assault vary as function of individual and contextual variables. This model seeks to examine. what relationship exists between remunerative and coercive control and incidence of assault net of inmate and prison-level controls. 18 Table 3.

Both inmates employed outside of the prison and inmates paid for work were significantly less likely to assault inmates. Coercive factors had no effect on inmate assault. The addition of the remunerative and coercive control variables explains about 6% of the total inmate—level variance. When contextual variables were added in model 2 the remunerative controls were no longer significant predictors of inmate assault (Table 2). Not surprisingly, all contextual variables added to the final model were significant predictors of inmate assault. Inclusion of prison-level controls also adds significantly to the model, explaining about 30% of the prison— level variance. It appears from the models that prison population, maximum-security facility, and South census region mediates the effect of remunerative controls on inmate-on—inmate assault. Remunerative controls have constant, significant effects on inmate-on-staff assault when compared to inmate-on-inmate assault (Model 1 in Table 3). In the preliminary model staff assault model, inmates employed both inside and outside of the facility were significantly less likely to assault staff. No effect was found for coercive control measures as predictors of staff assault. Inclusion of the remunerative and coercive control variables explains about 7% of the prison-level variance. 20 Table 3.

Maximum-security facility‘ was the only significant contextual predictor of staff assault. Eighteen percent of the total prison- variance is explained by the remunerative, coercive, and prison- level control variables. Administrative-Control and Prison Violence The results from the full model indicate that there is a significant relationship between remunerative controls and inmate and staff assault; however, the relationship is more complex than originally anticipated. It appears that not all forms of assault are equivalent. Incidence of assault was determined by a variety of factors. Determinants of assault also vary with the target of the assault. This is evidenced from the findings from the full HLM models. In the inmate assault models, both paid work and work outside the facility were significant predictors of inmate assault. However, when prison-level controls were added to the model the effects of the remunerative control variables were nullified. The staff assault models were not effected as significantly by the prison-level controls. Emisoners employed within or outside the prison were significantly less likely to assault staff despite the inclusion of individual and prison- level controls. As important as the significance of remunerative control variables on assault, is the lack of significance for the 22 coerciwe control variables. Traditional administrative-control theorists have argued that control is essential for proper corrections.:management (DiIulio, 1987; Kantrowitz, 1996). It appears from these models that coercive controls do little to mediate or exacerbate individual incidents of assault. Further research should. be conducted to determine the true power of coercive controls within correctional facilities. Subculture of Violence Thesis The relationship between subculture of violence and inmate violence is also more complex than originally anticipated. In the fixed-effects models African American was a significant predictor of inmate-on-inmate and staff assault; however, in the final model of inmate on staff assault African American was no longer a significant predictor. African American remains significant in all inmate-on-inmate assault models. In the same light, South census region is a significant predictor of assault in all inmate-on-inmate assault models, but has no effect in the inmate on staff assault models. It is evident from the models that African Americans have an increased inclination toward inmate violence; however, when remunerative and prison-level controls are included in the model the relationship between race and inmate assault changes. Discussion Multi-level analyses of inmate violence have been rare in 23 corrections research. More exceptional is tflua examination and development of administrative-control constructs as predictors of prison misconduct. This study attempted to address these limitations and to expand the knowledge within the administrative-control perspective . The goal of this analysis was not just to examine the role of incentive and punishments on inmate assault, but to examine the role of remunerative and coercive controls net of traditional variables. This study provides additional support for traditional models of prison misconduct; however, it also provides evidence that remunerative controls are able to mitigate incidence of assault net of traditional control variables. Although the findings presented provide intriguing results, two caveats should be noted. First, it difficult to evaluate the validity of self-report data provided by inmates. Although the accuracy of self-report data is always in question, researchers have suggested that higher levels of rule infraction are reported in self-reported studies when compared to official prison records (Hewitt et al., 1984). From this analysis, it can be assumed that self-report data may provide an expanded understanding of inmate assault then would have been discovered from an analysis of official records. In the same light, it is difficult to ascertain biases that may effect ticketing for rule infractions (Harer and Steffensmeier, 1996:353). Because of the nature of the data, it was also impossible to evaluate the relationship between specific types or length of work programs on assault. It may be that certain forms of work 24 programs are more meaningful for prisoners or that long work hours prevent assault; however, it was impossible to ascertain the relative importance of specific forms of programming on inmate and staff assault. Further research should be conducted to examine specific forms of remunerative controls on inmate assault and other forms of misconduct. Despite the relative limitations of the data, it appears that remunerative controls can mediate the effects of traditional determinants of inmate assault. It remains unclear; however, why remunerative control measures had varying effects (n1 different forms of assault. Etzioni (1961) posits that effectiveness of remunerative controls may be negatively related to amount of alienation experienced. Because prisoners experience a great deal of alienation, they may be less responsive to remunerative controls. Inmate assault also has been associated with traditional inmate culture and the subculture of violence; therefore, remuneration may be nullified by inmate culture for certain crimes (Harer and Steffensmeier, 1996; Irwin, 1980). Inmate assault on staff is a serious crime and perhaps out of the realm of cultural control; hence, remuneration may be more effective in preventing staff assault. The results presented in this study appear to suggest that there nay 1x3 an interaction between remunerative control and culture; however, further research is needed to understand the true nature of the relationship. 25 Appendix A Description of Variables Outcome variable Physical Assault on Staff Physical Assault on Inmate Explanatory Variables Inmate-Level Predictors Age Education Criminal History Citizen Married Gang Involvement 26 “Since your admission, how many times have you been found guilty of physical assault on a correctional officer or other staff member?” “Since your admission, how many times have you been found guilty of physical assault on another inmate?” Inmates’ years. age measured in Highest grade inmate attended before admission to prison. A four item factor score (eigenvalue = 1.20) including total sentence in years, currently serving for a violent crime, age at first arrest, and number of prior arrests. A dummy variable with 1 = citizen and 0 = non-citizen. A dummy variable with 1 = married and 0 = not married. A four item additive scale, measuring participation is varying levels of gang organization including: members of gang from same area, gang territory, formal gang membership, and known gang leader (Cronbach’s Alpha = 0.79) Appendix A Description of Variables African American Other Hispanic Length of Incarceration Prison-Level Predictors Remunerative Controls Outside Work Assignment Prison Employment Paid Work Assignment Cocrcivc Controls Solitary Confinement 27 A dummy variable with 1 = African American and 0 = non- African American. A dummy variable with 1 = other race and O = not other race. A dummy variable with 1 = Hispanic and 0 = non- Hispanic. Inmates' length of incarceration calculated from year that inmate entered prison. Percent of total inmate population that is employed outside prison grounds. Percent of total inmate population that is employed within the prison. Percent of total inmate population that is paid for work. Percent of total inmate population that received solitary confinement as a disciplinary response to the most recent rule violations. Appendix A Description of Variables Coercive Control 28 Two item factor score (eigenvalue = 1.32; factor loadings > 0.79) including: Percent of total inmate population that lost a work assignment as a response to the most recent rule infraction and percent of total inmate population that lost general privileges as a response to the most recent rule infraction.
