The comparison was made along four classes of social network variables: (a) structure, the basic morphological characteristics; (b) content, the nature of shared activities; (c) function, the transaction of support; and (d) emotion, the experiencing of affect. A secondary, yet essential, purpose was the evaluation of the research assumption, conceptually basic to much of the previous research, that self-report data are a sufficient and reliable indicator of the actual status of the social network. The concepts of schizophrenic withdrawal and isolation represent the theoretical basis of this study. The isolation hypothesis posits that the person becomes schizophrenic as a result of being isolated socially. The withdrawal hypothesis posits that as the schizophrenic disorder progresses, the affected person becomes withdrawn. Support was found in the review to substantiate social withdrawal and isola- tion as interacting and reciprocal. Kenneth Lee Carrico, Jr. The normal sample was composed of 18 subjects and the schizo— phrenic sample, of 17 subjects. All subjects were aged between l8 and 40 years and were living with family. Selection of the subjects was designed to promote comparability along those dimensions that affect outcome (age, sex, race, socioeconomic status, and cultural back- ground), yet insure the identification of appropriate subjects from both populations. Notably, the schi20phrenic sample was characterized as willing to participate. The methodology of the study consisted of two phases, the corrobo- ration of self-report data within both samples and the comparison between the two samples along l6 social network variables. In both phases, the analyses were implemented through the use of multivariate and post hoc univariate statistical procedures. In the first phase, as the self-report of both samples was not adequately corroborated, the conclusion was drawn that self-report data are an insufficient, possibly inaccurate, and unreliable source of information in social network analysis. This conclusion seriously challenges the assumption made by previous researchers who viewed self-report as sufficient and reliable. Furthermore, the conclusion was drawn that the schizophrenic's perception of social relationships was as reliable as the perception of the normal-~a startling conclu- sion. Having far-reaching implications, evidence was also found to support the contention that the lack of reliability of self-report measures limited the power of the statistical tests to make compari— sons between the two groups. In line with these findings, the conclu- sion was drawn that the self-report data represent solelyifimeperceptions Kenneth Lee Carrico, Jr. of the subjects regarding their social networks, not the actual status of the social networks. In the second phase, the comparison between the social networks of the normals and schizophrenics, significant differences were found in relation to only two network variables, perceived network size and reciprocity. Both results are in line with previous research. The mean perceived network sizes of the social networks of normals and schizophrenics were found to be 36.23 and 12.65, respectively, imply- ing that the schizophrenics perceive themselves surrounded by fewer "important" persons. In terms of reciprocity, the conclusion was drawn that normals perceived their relationships as reciprocal in terms of support, whereas schizophrenics perceived their relation- ships as lacking in reciprocity, placing the schizophrenic in a depend- ent position in his/her self-perception. The presence of significant findings along only 2 of l6 variables provided weak support for the hypotheses of withdrawal and isolation. Furthermore, the relative lack of significant differences challenged two consistent findings in previous studies, namely, fewer multiplex relations and negative emotional perception in the social network of the schizophrenic. DEDICATION To my social network, in the context of which I came into exist- ence and evolved as a human being. But especially my parents, the true cornerstones of my personality, to whom I owe my creation, preservation, and foundation--debts never paid, yet never outstanding. And my wife, Joanne, the sunshine of my life, for her emotional support, unswerving confidence, and all the love one man could imagine. And my children, Dianna, Katherine, and Kenneth III, the radiant stars of my life, ever propelling from me, yet forever close to my heart. And my granny, whose divine love, grasp of spiritual truths, and faith in God quickened in me a quest for knowledge and truth and instilled in me, like three granite columns, faith in others, my Self, and God. And last, Dr. Peter L. Giovacchini, my analyst, who freed me from inner shackles and burdens, enabling the exquisite realization of two major life goals, my marriage and the completion of my Ph.D. ii ACKNOWLEDGMENTS My deepest gratitude is extended to the members of my dissertation committee for their sponsorship of this research. To Dr. Norman R. Stewart, my advisor and cxmmfittee chairperson, I am chiefly indebted as he was the central figure in my studies as well as the dissertation research. His continuing availability, openness, candor, guidance, and constructive criticism were invaluable contributions to my project. To Dr. William H. Schmidt, I owe much for his consultation on statistics and methodology. On a personal level, his humor, interest, and encour- agement were deeply appreciated. To Dr. Thomas Stachnik, I am indebted for his insightful understanding of the goal of my project and singular contribution to the study associated with data corroboration. To Dr. Herbert M. Burks, I am greatly indebted for his editing and atten- tion to detail, as well as professional grasp of nuances of style and methodology. His commitment to my education is hopefully reflected in this document. The support of several institutions providing research sites for the study was essential for the completion of the research. I am fore- most indebted to Dr. Karl Willrich, Director of Adult Programs, and Dr. Truman G. Esau, Medical Director, of Old Orchard Hospital who wholeheartedly endorsed the research and continually supported my efforts throughout the months of data collection. Notably, Dr. Karl Willrich introduced this researcher to the clinical relevance of the iii family and social network, providing the initial impetus for the direction of this research project and a strong formative influence on my professional development. I would also like to recognize the following persons in that they were the primary representatives of the other participating institutions: Dr. Charles E. Turk, Medical Director, and Doris L. Lefley, Program Coordinator, of the Day Treat- ment Center at the Elk Grove/Schaumburg Townships Mental Health Center; Dr. Anthony M. D'Agostino, Chairman of the Department of Psychiatry and Medical Director of the Mental Health Unit and Alcohol Treatment Center, and Sandra L. Spencer, Head Nurse, of the Niehoff Pavillion at the Alexian Brothers Medical Center; and Dr. Edward J. Baranowski, Executive Director, and Mr. Sheldon Gross, Director of the Day Care Program, at the Main Center for Mental Health. I am, of course, deeply indebted to the direct participants in my research, namely the subjects, who shared their time and lives in the continuing pursuit of scientific knowledge. My employer, the Elk Grove/Schaumburg Townships Mental Health Center, supported without question or equivocation the completion of this project. The administrative and clinical staff were encouraging and responsive to my needs for flexible scheduling, and unpredictable and extended leave. I am particularly indebted to the members of the Crisis/Emergency Team: Program Coordinator, Richard S. Bloom, A.C.S.N.; and staff members, Florence Anderson, Robert J. Dziewior, Denise Elliot, and Stephen Jzaska. These persons shared extra burdens and responsi- bilities during my absences and endured by psychological aches and pains. iv A word of appreciation seems very appropriate for my patients as well. While attempting to cope with their emotional burdens and loss, they were additionally confronted with my limited availability, unpre- dictable absences, and at times, preoccupation. I owe special gratitude to a very warm and committed friend, John E. Laycock. As this document was completed out-of—state, neces- sitating several commuting trips from Chicago, John repeatedly opened his home without hesitation. He endured the unpredictability of last- minute planning and cancellations, late arrivals, scheduling conflicts, and precipitous departures. His hospitality and friendship were, and are, of the highest quality. God's speed is wished to him in his new endeavor, training for the priesthood. Finally, I salute my wife and children, who dutifully endured the many emotional and financial privations in our family life to support my work and my need for solitude. Their patience and deter- mination were sources of inspiration for me. Indeed, their task was as demanding as mine. TABLE OF CONTENTS LIST OF TABLES ........................

Attempts have been made to relate its occurrence with various fac- tors such as genetics, physiology, body chemistry, individual dynamics, family process, and sociocultural influences. Each viewpoint has had a degree of explanatory power and heuristic value; all, perhaps, have shed light on the genesis/process of the schizophrenic disorder. Accordingly, multitudes of theories have evolved out of the research, making integration of the work a massive and seemingly endless pro- cess. In the present study, which focuses on the psychosocial aspects of schizophrenia, a new concept and methodology developed in the field of social anthropology will be used which shows promise in providing a unifying framework for the psychological and social theories: social network analysis. Social network analysis allows for the quantifica- tion and assessment of differing levels of conceptualization, e.g., the personal, the familial, and the sociocultural; thus, the effects of all investigated levels are recognized, permitting further inte- gration. Statement of the Problem Previous investigations of the social networks of schizophrenics have demonstrated relationships between social network variables and the schizophrenic, suggesting associations between psychosocial fac- tors and the schizophrenic disorder. Inchoative trends in the research suggest that the social network of the schizophrenic tends to be smaller than that CH the normal, nonpsychotic control. Additionally, the relationships of the schizophrenic appear to be characterized more by a lack of reciprocity (in particular, the schizophrenic being in a dependent position) and a limited range of activities compared to the control. Interpretations made from these results point out that the schizophrenic appears to have a less unified and realistically smaller system of social resources than the control. Furthermore, being that this person is predominantly the dependent party in the social net- work, this small network may be quite taxed to support this person. Last, assuming that quality of relationships is related to the range of activities shared, it would appear that the relationships of the schiZOphrenic are less satisfying and enriching than those of the control. Although these investigations appear quite promising, the findings are far from being conclusive because of frequent and notable incon- sistencies in the results and the presence of a serious conceptual error in the studies. The inconsistencies in the results prohibit a strict relating of the specific, discrete social factors to the schizophrenic disorder. An examination of the literature suggests that the overall lack of concordance in the studies is related to the following considerations: (a) inadequate sample descriptions and dif- fering populations, (b) differences in conceptualization and opera- tionalization of variables, (c) differing conceptualizations of the social network under study, and (d) inconsistencies in the reported data. Furthermore, a serious conceptual error calls the findings into question. The assumption was made in three of the four pivotal studies that the subjects' subjective analysis of the status of their social network, i.e., the self-report data, was equivalent to the actual status of the network. The investigators may have only been interested in their subjects' perceptions (and such would be quite important clinically), but inferences were drawn unequivocally to the social network, as if self-report was indeed factual. Attempts were not made to corroborate the reported data with more objective measures or with reports of others in the network. Thus, the validity of the results lacks credibility. Purpose of the Study The major purpose of this research study is to compare the social networks of normals and schizophrenics, the goal being identification of psychosocial factors that appear to be associated with the schizo- phrenic disorder. In this study, the two groups, normal and schizo- phrenic, will be compared along four major classes of variables pertaining to social networks and relationships: structure, content, function, and emotion. The structure-related variables convey the basic morphological characteristics of the social network. The content-related variables convey aspects of the content of the social relationship, i.e., the types of shared activities. The function- related variables reflect the transaction of support. And last, the emotion-related variables assess the experiencing of affect in the social network. Also, a secondary purpose of the study is to evaluate the research assumption, conceptually basic to much of the previous research, that self-report is a sufficient and accurate indicator of the actual status of the social network. To accomplish this task, the self-report of five normal and five schizophrenic subjects will be compared with the report of at least four of their network members on the status of the shared relationship to corroborate the data and obtain some estimation/measures associated with validity. This assessment will be carried out prior to the main analysis as the meaningfulness of the results depends upon it. If it is determined that the self-report data are not truly representative of the actual status of the social network, then the statistical results of the main analysis will not be examined in relation to their more interactional and sociological meaning, but rather to their strictly clinical significance, since the observations do not correspond to a reality based on consensus. Definitions General Definitions Family of origin. A social unit composed of maternal and/or paternal figure, and their offspring and/or stepchildren only, in which the focal person is an offspring or stepchild. Focal person. The individual who is considered to be the focus or point of origin for the analysis of a social network within this study: The focal person is the subject, unless otherwise noted. In the fields of sociology and social anthropology, the term ”ego" is traditionally used to designate this focal person. General usage of the term "ego" differs significantly from this formal definition and is associated with psychoanalytic theory. Thus, the term ”ego” was not chosen for usage in this research, as this study is expected to have wide applicability and value outside the professional boundaries of these two fields. Accordingly, to avoid initial confusion with the more usual psychoanalytic usage of the term "ego" and possibly later specious connotations, the term ”focal person” is being used. Kin or kinship system. Individuals related by blood or marriage. Nuclear family. A social unit composed of a maternal and/or paternal figure, and their offspring and/or stepchildren only, in which the focal person is a parent or stepparent. Primary star. Those relationships (linkages in the social net- work) that exist solely between the focal person and his/her social network; interrelationships among the network members are thus excluded. Schizophrenic disorders. The group of disorders that share the following essential characteristics as outlined by the American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, III (1980): 1. presence of certain psychotic symptoms during the active phase of the illness, e.g., delusions, hallucinations, poverty of and/or loosening of associations; 2. deterioration from a previous level of functioning in social relations, self-care, and at work; 3. characteristic symptoms involving multiple psychological processes including disruptions in content and form of thought, perception, affect, identity, volition, relation- ship to the external world, and psychomotor behavior; 4. onset before age 45; and 5. duration of at least 6 months. (You are referred to the manual for an extensive discussion of the disorders.) No differentiation relative to subtype was made. Social network. Those individuals with whom the focal person has an important personal relationship as defined by the focal person, whether positive or negative in nature, with nuclear family, family of origin, other blood relatives, relatives by marriage, friends, neighbors, associates at church, work, school, etc. The usual defini- tion of social network in the field of social anthropology applies to a larger matrix of interrelated individuals. The given definition strictly applies to a personal network or what is termed "immediate network." Definitions Referring to Structure Adjacent density. This index refers to the proportion of link- ages (relationships) in the network to the possible number of linkages in the given network. Interconnectedness. Interconnectedness refers to the relation- ships that exist within the social network, including but beyond those of the primary star. The index, adjacent density, assesses this structure-related quality. Structure-related variables. These variables convey the basic morphological characteristics of the social network. The four structure—related variables are size of the network, frequency of contact, distance between the focal person and network members, and adjacent density. Definitions Referring to Content Content-related variables. These variables convey the content of the relationship between the focal person and the social network (actually the primary star). In this study, content is strictly defined as type of activity. Ten content-related categories (types of activities) were selected with the intent of assuring that the areas were inclusive of most activities: family, employment, romantic, con- versational, social, recreational, fraternal, religious, political, and volunteer activities. The content of the relationship (the types of activities that characterize a relationship) is presumed to be associated with quality within the relationship. Multiplex relationship. A content-related variable character- izing a relationship of more than one type of content, i.e., where the focal person and the network member share more than one type of activity. Relationship density. A content-related variable expressing the intensity and quality of relationships in the primary star of the social network, i.e., solely between the focal person and network members. (Note: The content of the other relationships within the social network is not assessed, since the information would not be considered reliable unless the others were examined.) Uniplex relationship. A content-related variable characterizing a relationship of only one type of content, i.e., where the focal person and the network member participate in only one type of activity. Definitions Referring to Function Functional directionality. A quality of the functioning of a social network that refers to the direction in which support flows between the focal person and another in the social network. If sup- port goes in equal measure between the focal person and the network member, then the relationship is reciprocal and thus is character- ized by functional symmetry. If the support goes in unequal measure between the two, then the relationship is functionally asymmetrical. Functional indegree. A function-related variable indicating the degree to which functions are being served for the focal person by a network member, i.e., the support the focal person is receiving. The usage of this term is to be distinguished from the term as used by Tolsdorf (1976), which refers to the numbg:_of functions served for the focal person. Functional outdegree. A function-related variable indicating the gggy§e_to which the focal person is serving functions for a network member, i.e., the support the focal person is providing for the network member. The usage of this term is also to be distinguished from the term as used by Tolsdorf (1976), which refers to the numbe:_of func- tions that the focal person serves for the network member. Definitions Referring to Emotion Affective directionality. A quality of the emotion-related variables that refers to the direction of the emotion experienced between the focal person and the network member. If the type of emo- tion between the focal person and the network member is identical, then the relationship is reciprocal and thus is characterized by affective symmetry. If the type of emotion between the two varies, then the relationship is characterized by affective asymmetry. Affective indegree. An emotion-related variable indicating the types of feelings a network member experiences for the focal person as perceived by the focal person. The range extends from all negative to all positive feelings. Affective outdegree. An emotion-related variable indicating the types of feelings experienced by the focal person for a network member. The range extends from all negative to all positive feelings. 10 Investment directionality. A quality of the emotion-related variables that refers to the direction of the emotional investment (literally, the strength of the emotion) between the focal person and the network member. If the strength of the emotions experienced by the focal person and the network member is equal, then the relation- ship is reciprocal for strength of emotion, and thus is characterized by investment symmetry. If the emotional investment varies between the two, then the relationship is characterized by investment asym- metry. Investment indegree. An emotion-related variable reflecting the strength of feelings (emotional investment) experienced by the network member for the focal person as perceived by the focal person. The range extends from weak to very strong feelings. Investment outdegree. An emotion-related variable reflecting the strength of feelings (emotional investment) experienced by the focal person for a network member. The range extends from weak to very strong feelings. Major Hypotheses The research study is intended to be an exploration of the inter- personal and social processes operating in the schizophrenic disorder. The specific goal is to isolate those properties that distinguish the social networks of the schizophrenic person from the social networks of the normal person. The four major hypotheses (grouped by primary area) that identify the avenues of focus follow: 11 In terms of the structure-related or morphological variables, the soc1a1 network of the schizophrenic person, as opposed to the normal person, tends to be characterized by the following properties: a. Fewer network members; specifically, it is hypothesized that the social network of the schizophrenic person is smaller than the social network of the normal person. A lesser proportion of interrelationships among network members (less interconnectedness); specifically, it is hypothesized that the social network of the schizophrenic person is less interconnected than the social network of the normal person. A lower average distance between the focal person and the network members; specifically, it is hypothesized that within the social network, the members live closer to the schizo- phrenic person than the members of the social network of the normal person. A relatively higher frequency of contact with the focal person; specifically, the schizophrenic person tends to have more contact per person with the network members than the normal person. In terms of the content—related variables (those dealing with the nature of shared activities), the social network of the schizophrenic person, as opposed to the normal person, tends to be characterized by the following properties: e. f. g. A greater proportion of relationships in which only one activity is shared (proportionately more uniplex relation- ships); specifically, it is hypothesized that the schizo- phrenic person tends to have relatively more relationships than the normal person in which only one type of activity is shared within the dyad. A smaller proportion of relationships in which more than one activity is shared (proportionally fewer multiplex relation- shipS); specifically, it is hypothesized that the schizo- phrenic person tends to have relatively fewer relationships than the normal person in which two or more activities are shared within the dyad. A relatively smaller_prpportion of shared activities per personTless relationship density); specifically, it is hypothesized that the schizophrenic person tends to share fewer activities per member of the social network than the normal person. 12 In terms of the function-related variables (those dealing with the transaction of support within the social network), the social network of the schizophrenic person, as opposed to the normal person, tends to be characterized by the following properties: h. A_greater degree of support provided by network members to the focal person (more functional indegree); specifically, it is hypothesized that the schizophrenic person tends to receive more support per person from network members than the normal person. A smaller degree of supportyprovided by the focal person for network members (less functional outdegree); specifically, it is hypothesized that the schizophrenic person tends to give less support per person to network members than the normal person. A lack of reciprocity (functional asymmetry); it is hypothe— sized that whereas the normal person and the network members tend to give and receive in equal measure, the schizophrenic person tends to receive more from the network members than he/she gives them; i.e., the schizophrenic person tends to be dependent in relationships. In terms of the emotion-related variables, broken down into two major categories, affective and investment areas, the social network of the schizophrenic person, as opposed to the normal person, tends to be characterized by the following properties: k. A lesser degree of positive feelings from network members for the focal person (less affective indegree); specifically, it is hypothesized that the network members of the schizophrenic person feel more negatively toward the schizophrenic person than the network members of the normal person toward the nor- mal person. A lesser degree of positive feelings from the focal person for the network members (less affective outdegree); spe- cifically, it is hypothesized that the schizophrenic person feels more negatively toward the network members than the normal person does. Affective asymmetry; specifically, it is hypothesized that whereas the normal person and the network members tend to feel similarly toward one another, the schizophrenic person tends to feel more negatively toward the network members than they toward him. A greater degree of emotional investment of network members in the focal person (more investment indegree); specifically, it is hypothesized that the network members of the schizophrenic person are more invested in the schizophrenic person than are the network members of the normal person in the normal person. 13 o. A lesser degree of emotional investment of the focal person in network members (less investment outdegree); specifically, it is hypothesized that the schizophrenic person is less invested emotionally in the network members than is the nor- mal person. p. Investment asymmetry; specifically, whereas the normal person and the network members tend to be similarly invested in one another, the schizophrenic person tends to be less invested in the network members than they in him. Before this analysis can be undertaken, the data from the subjects' self-report must be examined to determine if they are in actuality an accurate and sufficiently representative indicator of the functioning of the social network. The following research hypothesis is posited: Self-report on the status of the social network is adequately corroborated on all designated measures by reports of the network members in both samples: normal and schizophrenic subjects. If the above hypothesis is not confirmed, then the following research hypothesis is posited: The difference between the self-report of the schizophrenic sub- ject and the network members is larger than the difference between the self-report of the normal subject and the network members. Overview In the review of the literature, the following topics are covered in a selective fashion to examine only those aspects relevant to the purpose of this study, the social network analysis of normals and schizophrenics: (a) importance of the study, (b) social network analysis, (c) theoretical perspective--the concepts of schizophrenic withdrawal and isolation, (d) key variables, (e) importance of the social network to the schizophrenic disorder, and (f) relationships between social network variables and psychopathology, in general, and the schizophrenic disorder, in particular. The extremely disrupting 14 effect of the schizophrenic disorder upon the individual and society is reviewed to demonstrate the general importance of the study. Social network analysis is reviewed in terms of its history and development, a point of controversy, and differing and inter- related conceptualizations. Specifically, the review of history and development indicates how the concept of the social network initially emerged as a metaphor in the research to later develop into an analyti- cal tool of wide applicability and value; the review of one controver- sial point indicates that social networks have been viewed by some as ”informal residuals" unworthy of study, but by others as the key to a new and important type of methodology in social science; and the review of differing conceptualizations provides descriptions of the different perspectives present in social network analysis. The review and discussion of schizophrenic withdrawal and isolation is used to develop a theoretical perspective of how the schizophrenic disorder is associated with the social network. Based on this theoretical framework, the review of the key variables provides an understanding of their psychological and social implications which is crucial to the analysis and interpretation of the results of the study. In the next section, general importance of the social network to the schizo- phrenic disorder, the components of the social network, i.e., mother, father, family, extended family, and significant others, are reviewed to demonstrate possible relationships to the schizophrenic disorder and to examine the nature of those influences, thereby contributing to the understanding of the role of the social network. The research investigating relationships between social network variables and 15 psychopathology, in general, and the schizophrenic disorder, in par- ticular, is reviewed to demonstrate the presence of associations between social factors, and psychopathology and the schizophrenic disorder, to identify the sources of inconsistency and potential lack of credibility in the related studies, and last, to suggest alternative, corrective methodologies. General Importance of the Study The schizophrenic disorder is a worthy area of study because of its extremely disrupting impact upon the affected individual and society. Generally, the schizophrenic disorder is recognized as the most severe and debilitating psychopathological disorder. Day and Semrad (1978) advanced the following: The schizophrenic reactions are a group of diseases that cause massive disruptions of thinking, mood, sensorimotor function- ing, and behavior; they lie at the most severe end of the spec— trum of psychopathology. Schizophrenics show a greater degree of disturbance in intrapsychic function, character structure, and interpersonal relationships than patients suffering from any other disorder. (P- 199) Arieti (1974) considered the disorder to be a psychosis which, in his opinion, is generally accepted as a "severe or major psychiatric dis- order" (p. 4). Reid (1975) stated regarding the schizophrenic dis- order, "It is often catastrophic in effect, taking its toll during the most productive years of an individual's life" (p. 299). Not only is the schizophrenic disorder a serious psychiatric problem for the affected individual, but it is also a critical concern of major proportions societally. In 1969, Ullman and Krasner found that the schizophrenic reactions compose the largest group of the 16 psychoses. Furthermore, they stated, “At the present time roughly 20 percent of all first admissions to psychiatric hospitals are cate- gorized as schizophrenic. Even more important, roughly half of all patients remaining in psychiatric hospitals are diagnosed as schizo- phrenic" (pp. 356-357). Reid (1975) reported that approximately 1% of the general population will be diagnosed as schizophrenic at least once during their lifetime. In terms of incidence, Day and Semrad (1978) in their review found that approximately 92,450 to 148,350 new cases appear each year, and that between 494,500 and 1,010,500 are in treatment for a schizophrenic disorder annually in the United States. Last, they stated, "The total direct and indirect cost of the schizo— phrenic disorder to the United States is estimated to be $14 billion annually" (p. 207). Social Network Analysis History and Development Social network analysis was developed in the field of social anthropology as a methodology for the study of social relationships (Hammer, Makiesky-Barrow, & Gutwirth, 1978; Whitten 8 Wolfe, 1973). During the initial stages when the concept of social network was used primarily as a metaphor, Hammer et a1. (1978) noted that the social network generally referred to "interpersonal relationships which crosscut the well-defined groups and sectors of pre-industrial societies, giving a measure of integration or cohesion to otherwise discrete segments" (p. 523). At this point, the fields of sociology and anthropology were oriented toward the investigation of more formal 17 and well-defined groups than those determined by interpersonal processes. Later, as interest grew, social network analysis evolved into a more analytical tool of reseamtil which has been applied to a wide range of social phenomena and problems, demonstrating its value and applicability, e.g., conjugal roles (Bott, 1955/1977; 1957), political movements (Gerlach & Hine, 1970), medical practices (Coleman, Katz, & Menzel, 1957), etc. (You are referred to the articles by Hammer et al., 1978, and Whitten 8 Wolfe, 1973, for a more extensive review.) A Point of Controversy Throughout its early development, a controversy raged over the relevance and importance of the social network concept (as the earlier paragraph--above--might suggest). In examining the literature, Whitten and Wolfe (1973) identified a dominant trend toward perceiv- ing social networks as ”residuaZ--the relationships that remain after the major structural relationships are dealt with" (p. 722). Essentially, social relationships were not seen as important social phenomena worthy of study, but rather as links or connections to fill the voids between the formal units of social structure. The work of Barnes (1954), Redfield (1956), Wolf (1966), and Boissevain (1968) were quoted to identify this viewpoint. Other researchers, particu- larly Mayer (1962, 1966), Mitchell (1969), and Gutkind (1965), tended to regard the social network as a singularly important concept, allow- ing for the integration of personal, social, and cultural variables, documenting their independent action and interplay. 18 Conceptual Bases Although social networks tend to be recognized now as both focal and important, there is a great deal of variance among researchers as how to proceed in the analysis of networks. Researchers' con- ceptualizations tend to be based on the focus and needs of their research. Five notable types of conceptualizations, relevant to the present study, are reviewed below based on the following methods of categorization: (a) set theory applied to categories of relation- ships, (b) levels of linkage to the focal person, (c) zones of inti- macy in relationships, (d) the objective and subjective nature/ perception of networks, and (e) clinical relevance of relationships. Each contributes to a different perspective on the composition of social networks. One type of conceptualization is based on the categorization of relationships in the social network by set theory. Wolfe (1970), for example, has developed a "taxonomy of network concepts," based on the structure and process operating within the social network. In his schema, networks are first divided as to whether they are seen as limited or unlimited. Limited networks are considered a subsection to the total (unlimited) network and are based on some criterion applicable throughout the total network. Five types of limited net- works were described: (a) the personal set, limited to the links of one person; (b) the categorical set, limited to links involving per- sons of certain type of category; (c) the action set, limited to links purposefully used for a specific end; (d) the role-system set, limited to links involving a certain role system; and finally (e) the 19 field set, limited to links with certain content. The unlimited network was conceived of without limiting criteria, and could be expanded to include villages, societies, continents, etc. Thus Wolfe's system is based on categorical arrangements within limited or unlimited sets. Hammer et a1. (1978) distinguished among three linkage levels or orders of an individual's social network: The immediate or personal network consists of the connections linking a given individual with others and the connections linking those individuals with each other; The initia1 individuaI's second order network consists of the connections linking the members of the immediate network with their immediate networks; and The extended network includes the further connections linking these sets of individuals into larger populations. (p. 524) Thus Hammer and her associates have developed a system which is keyed into the structure of the social network. Another type of conceptualization is based on zones of intimacy and subjective importance in relationships. Boissevain (1974) has articulated six levels or zones which radiate conceptually around the focal person in concentric circles, constituting the person's first order zone: The lower the number of the zone, the more intimate and subjectively important are the persons to the focal person. The first level, the personal cell, hypothetically contains the closest relatives, such as one's nuclear family or family of origin, and a few of the most intimate friends: Within the personal cell, the contact and interaction is usually regular, frequent, and intense. The second level, intimate zone A, is composed of very close rela- tives and friends in which active contact and interaction are 20 maintained. The third level, intimate zone 8, consists of friends, relatives, neighbors, and perhaps, co—workers who are emotionally significant to the focal person, but the relations are more passive than in intimate zone A. The fourth level, the effective zone, is composed of those who are important "in a more pragmatic sense for economic and political purposes and the logistics of daily life” (p. 47). These relationships are maintained warm and congenial because the focal person desires access to his/her friends for strate- gic reasons; thus, their importance is based on instrumental, rather than emotional, importance. The fifth level, the nominal zone, con- tains persons who mean little to the focal person emotionally and instrumentally, simply acquaintances. The names and faces of these persons may be uncertain to the focal person. The sixth level, the extended zone, is composed of those forgotten where recall would need to be prompted. In conclusion, Boissevain noted, "Placement in these zones is continually shifting: just as the transactional and emotional balance in them is constantly shifting. From this perspective a per- son's network is a fluid, shifting concept" (p. 48). The objective and subjective nature of the social network, which relates directly to analysis, is another way of conceptualizing. Pattison (1977) described this method of dichotomizing the content of a network. According to this approach, the objective network is defined by the specific goal/purpose of the researcher, and this net- work could be observed. For example, a work network is composed only of those observed at work or a political network is composed of only those observed or recorded as participating in a political campaign. 21 On the other hand, the subjective network can be only defined by the focal person, as guided (not defined) by the criteria of the researcher. As indicated by Pattison, the subjective network may include parts of objective networks, e.g., family network, work network, friend net- work, etc. The fifth type of conceptualization relates to the composition of the social network in terms of the clinical relevancy of relationships. To this end, Pattison, de Francisco, Wood, Frazier, and Crowder (1975) have defined a social network called the psychosocial kinship system. Through their review, they supported the conclusion that the American family is surrounded by a significant extended kinship system composed of blood/marriage-related family and/or functional kin (those who respond interpersonally as family) of friends, neighbors, work asso- ciates, and others. Furthermore, they suggested that this identified social group, not the family, is the basic and important social sys- tem and accordingly, is associated with the individual's functioning. (Unfortunately, Pattison et a1. did not distinguish by title between the total group of the extended kinship referred to above and the potential subgroup defined by meaningfulness and psychodynamic impor- tance described below, as both are called the psychosocial kinship system.) In relation to the significant extended kinship system, they concluded that (l) the psychosocial system does exist, (2) it exerts both positive and negative sanctions and supports on the nuclear family and the individual, and (3) it is a fundamental social matrix that may prove to be either pathological or helpful and therapeutic. (p. 1248) 22 Yet Pattison and his associates (1975) were not only interested in investigating this social group, but also those within this group, and perhaps, a group beyond it, who are meaningful to the individuals. They stated, Social psychologists have found that affinity by mere blood or marriage does not define meaningful kin relationships and that a causal definition of friend, neighbor, or work asso- ciate does not define a significant psychodynamic relation- ship. (p. 1248) The clinical relevance of the "psychosocial kinship system, the object of their study, was not only grounded in the social significance of the network of family, relatives, friends, and various associates, but in the psychodynamic significance these persons might have. In the article, Pattison et a1. stated the following: Our aim is to determine the psychodynamic social system that comprises the primary social matrix of the individual. The people in this matrix are related to the individual on the basis of interaction and valued importance. Thus the rela— tionships in the matrix are determined by social and psycho- logical variables. Further, this social matrix represents the functional kin group of the individual. Thus we term it the psychosocial kinship system. (pp. 1248—1249) In his personal communication, Pattison (1979, 1980) took an additional step of inference. He argued that if the focal person has a cathexis to another person (analytically speaking), then a linkage exists in the psychosocial kinship system; thus, the interactional or social component may be negligible or nonexistent. For this reason, a net- work member may not necessarily be alive or have ever interacted socially with the focal person, so long as the network member be psychically alive. That is why he prefixed the term with "psycho-," indicating the psychological component and indexing its importance. 23 The social network conceptualization to be used in the present study, chosen for its clinical importance, is the psychosocial kin- ship system as articulated by Pattison and his associates (1975). Contrasting this perspective with the other conceptualizations of the social network, the psychosocial kinship system appears to be a subjective network (Pattison, 1977), a product of the first four zones of intimacy (Boissevain, 1974), a subgroup of the immediate or personal network (Hammer et al., 1978) since the network consists of connections linking the focal person with others and connections link- ing the network members to each other, and in terms of structure, a limited personal set as only one focal person per network exists (Wolfe, 1970). Schizophrenic Isolation and Withdrawal: A Theoretical Perspective The two hypotheses of schizophrenic isolation and withdrawal constitute the basic theoretical perspective for the present study. All of the social network variables can be interepreted in light of these two hypotheses. In the following section of this chapter, Principal Network Variables, the social network variables are examined in relation to these hypotheses generally. Other more discrete and measurable influences that appear to be associated with these hypothe- sized phenomena of isolation and withdrawal, and that have been found to be related to the variables under study, are also examined. The hypotheses of schizophrenic isolation and withdrawal have two basically differing but interrelated interpretations. The isola- tion hypothesis posits that as a result of becoming isolated socially, 24 either the person becomes schizophrenic (a strict etiological inter- pretation) or the person at high risk of schizophrenia tends to develop this serious disturbance. This latter interpretation tends to be supported by a related and complementary hypothesis termed the social support hypothesis, which suggests that the presence and sup- port of the social network is instrumental in preventing the occur- rence of a psychotic break and maintaining the schizophrenic without further and recurring episodes (Beck, 1978; Cobb, 1976). The with- drawal hypothesis posits that as the disorder progresses, the affected person tends to become withdrawn; i.e., an essential characteristic of the schizophrenic disorder is the withdrawal from society. Each of these propositions appears to be the converse of the other: The former states that the schizophrenic condition arises or is precipitated by the social phenomenon of isolation, while the latter states that with the onset of the condition, the schizophrenic withdraws and the social phenomenon of isolation evolves. To more clearly understand the nature of these two influences of isolation and withdrawal, and the impact they may theoretically have on the schizophrenic and the social net- work of the schizophrenic, they are reviewed below. The Isolation Hypothesis The isolation hypothesis initially emerged as an etiological theory, but very little empirical support was found; however, isola— tion as a general social influence precipitating the schizophrenic disorder has received support. Faris (1934) appears to have originated the concept, stating that 25 Data from various sources appear to support the hypothesis that.the"shut-in" or "seclusive" personality, which is gen- erally considered to be the basis of schizophrenia, may be the result of an extended period of "cultural isolation," that is, separation from intimate and sympathetic social contacts. (p. 155) His evidence, in general, was based on two sets of impressionistic findings: (a) the characteristic seclusiveness in the schizophrenic disorder, and (b) anthropological findings relating the isolation phenomenon to schizoid symptomatology. Kohn and Clausen (1955) attempted to test the isolation hypothesis using the strict etiologi- cal interpretation. Their data, focusing on the adolescent years, were based on the retrospective impression of former, recovered patients. As only one-third of the patients reported a period of isolation in their adolescence, they wrote, "Our general conclusion must be, then, that for the group here studied the data do not support the hypothesis that social isolation in adolescence is a predisposing factor in either schizophrenia or manic-depressive psychosis” (P. 272). The etiological hypothesis was thus rejected. The investigators interpreted that the social isolation was a result of inadequacies in social relationships eventuating in alienation from peers: They stated, "Thus, in terms of process, social isolation is to be viewed as a sign that the individual's interpersonal difficulties have become so great that he is no longer capable of functioning in interpersonal relationships" (p. 273). This latter conclusion is more in line with the withdrawal hypothesis. However, a year earlier in an epidemiologi- cal study, Jaco (1954) interpreted the hypothesis in a less strict fashion as a general influence operating socially. He predicted that 26 the incidence of the schizophrenic disorder would be higher in areas characterized by more interpersonal isolation. His findings, based on 13 variables which relate to network size and degree of social contact (as well as employment stability and degree of mobility), tended to support his interpretation of the isolation hypothesis. Further, Jaco inferred that isolation acted as a precipitating factor. Thus the research does not support a strict etiological interpretation of the isolation hypothesis; however, an interpretation supporting a relative degree of social isolation as instrumental in the process of the disorder appears tenable. The related hypothesis focusing on the relationship between social support (loosely related to network size; i.e., with fewer network members available, less support is possible) and the schizo- phrenic disorder seems to support this conclusion that isolation may act as a precipitant, and for that matter, affect the course and out- come of the disorder. Day and Semrad (1978) have observed the type of onset apparently associated with a chronic developing pattern. They described the type of individual, at high risk for schizophrenia, who nonetheless has been able to cope with his/her needs and with society. Their gradual deterioration has been masked by a signifi- cant dependent relationship where the inadequacies and needs were met. With the loss of this person or persons, the deterioration becomes evident. In general, the work of Birley and Brown (1970), Jacobs and Myers (1976), and Jaco (1970) which focuses on stress and social support tends to substantiate these observations. The support role of the social network relative to course and outcome of the 27 schizophrenic disorder is cHscussed later in this chapter. (See section, General Importance of the Social Network to Schizophrenia.) Therefore, it appears that we can conclude that the degree of isola- tion is associated with the onset, course, and outcome of the dis- order. The Withdrawal Hypothesis Support for the withdrawal hypothesis consists of extensive clinical observations and theoretical formulations. The withdrawal of the schizophrenic person has been observed through the centuries, but Freud (1914/1956) was the first to attempt a coherent explanation dynamically. Basically, he viewed the schizophrenic withdrawal pro- cess as mentally endogenous and representative of narcissistic regres- sion. He expressed the view that the essential characteristic of schizophrenia was the change in relationship with people. In Freudian terminology, the schizophrenic person has withdrawn the libidinal cathexes from others and returns to a state of primary narcissism, totally withdrawn from others and cut off from social contact. According to Fenichel (1945/1972), current analytic thought does not accept such a pessimistic position, although the concept of narcis- sistic regression is still accepted. In his opinion, the schizo- phrenic can connect due to the presence of "residues of reality relationships" and "the patient's spontaneous attempts at recovery“ (p. 447); therefore, the "retreat from society" is never really com— plete. Other interpretations are reviewed by Arieti (1974): Fairbairn (1952) interpreted the withdrawal as an escape from inner bad objects 28 as they are projected on society; Szasz (1957), as an expression of an inner deficiency of preexisting objects which prohibits or limits future interpersonal functioning; Becker- (1962), as a deficiency of external objects, in that the person has been unable to find responses which reduce problematic situations into habits, and resultingly, develop meanings that will generalize into other interpersonal situa- tions; Sullivan (1953, 1962), as a consequence of unhealthy and anxiety-laden interpersonal relationships since infancy; and Cameron (1947), as a result of a failure to acquire intelligible communica- tion due to socially inadequate development. Arieti (1974) himself viewed the process of desocialization as a reflection of a "concomi- tant process occurring in the patient's inner reality“ (p. 345), in which the schizophrenic person is regressing to earlier forms of symbolization. Summarizing the process, he stated the following: By giving up common or socially shared symbols he desocializes himself. Although he may still use common symbols predominantly, the symbols that are involved in his delusions and more intensely experienced by him are his own paleosymbols. . . . As long as the patient uses private symbols, at least for the life situations that are most important to him, he cannot integrate socially. However, even the most regressed schizophrenic will retain expressions, words, and ways that belong to the interpersonal world. A total abandonment of what is obtained from others is not possible. (pp. 345-346) Thus several theoreticians have observed the withdrawal phenomenon and attempted to explain the process from a number of differing psy- chological and/or social perspectives, supporting its presence. Conclusion The two processes of social isolation and withdrawalirfthe schizo- phrenic can be seen as interacting and reciprocal. Arieti (1974) stated: 29 Inner life and external life are constantly interrelated: abnormal external relations early in life trigger intrapsy- chic mechanisms that disturb the inner 1ife. In its turn a disturbed inner life causes alterations in relating to others. A vicious circle thus originates. (P- 345) Additionally, support for the interaction of social and psychological events is generally provided by the theories of social psychology. Principal Network Variables The network variables discussed in this section relate directly to the stated hypotheses of the study. Each is categorized and evaluated as to the psychological and social implications associated with each variable. Understanding of these variables is crucial to the analysis and interpretation of the results: In contasting the two samples, these variables can be perceived as describing the psy- chological and social impact in type and degree due to the isolation and withdrawal of the schizophrenic. Network Size Network size, a structure-related or morphological variable, appears to be associated with the two hypotheses of schizophrenic isolation and withdrawal. This variable, in fact, would be a direct measure of the possible joint effect of the two hypotheses. It is predicted that due to the hypothesized impact of either or both influ- ences (an interaction) acting upon the schizophrenic, the social net- work of the schizophrenic would be smaller than the social network of the normal. 3O Interconnectedness Interconnectedness, a structure-related or morphological variable which refers to the sparsity or density of relationships (links or connections) within a social network, appears to be related with length of and closeness in relationships, and stability and support in social networks likewise affected by withdrawal and isolation. (Although researchers vary widely as to how this variable is opera- tionalized, it is considered to be a significant characteristic of social networks [Whitten & Wolfe, 1973].) The interconnectedness of close ties in a social network has been found to be positively corre- lated with the mean duration of contact in these relationships, indi- cating that forming highly interconnected networks takes considerably more time than loosely interconnected networks (Hammer & Schafer, 1975). In a review of this article, Hammer et a1. (1978) concluded, "Thus, for any individuals--including, of course, schizophrenic indi- viduals--a relative lack of long-term ties would tend to preclude anything more than peripheral participation in any interconnected network of close relationships" (p. 525), suggesting that a social network of relatively short duration would tend to be loosely inter- connected and contain members that are barely involved with each other. Further, a positive relationship has been found between interconnected- ness and maintenance of contact with close relationships in social networks during crisis with a psychiatric population (Hammer, 1961, 1963-64); specifically, patients whose closest relationships were with persons who were closely interconnected with each other tended to maintain their relationship during the crisis and ensuing 31 hospitalization. The implication is that the more highly intercon- nected the social network, the more stable, durable, and, accordingly, supportive (as the network does not deteriorate) the network tends to be. Therefore, as a variable, interconnectedness appears to vary with the length of the network's life, the degree of involvement and close— ness in the network, and the stability and support present in time of stress. The present study is designed to test if the degree of intercon- nectedness varies between the social networks of the schizophrenic person and the normal person, possibly due to differences in the life, degree of involvement, closeness, stability, and support characteris- tic of their respective social networks. The social network of the schizophrenic is predicted to be less interconnected as compared to the normal. Distance and Frequency of Contact The distance and frequency of contact between the focal person and the network members are likewise structure-related variables that appear to be related to the influences of schizophrenic with- drawal and isolation. Therefore, one would suspect that for the schizophrenic person, the distance and frequency of contact between the focal person and the network members would be lower than for the normal person; however, as the size of the network of the schizophrenic person is expected to be lower, the frequency of contact per person in the social network of the schizophrenic person is expected and pre- dicted to be higher. 32 It should be noted that an increased degree of contact within the social network may not always be better for the schizophrenic. For example, Vaughn and Leff (1976) have found that increased con- tact between the schizophrenic person and a family characterized by highly critical and emotional conflicts results in deterioration. Thus frequency of contact is not an independently related variable to the schizophrenic disorder. Uniplex and Multiplex Relationships and Relationship Densipy Uniplex and multiplex relationships and relationship density are content-related variables which appear to be associated with the quality of the personal relationship between the focal person and the network members; specifically, the more varied the activities within a relationship, the greater the degree of closeness and satisfaction (Bott, 1955/1977, 1957; Brim, 1974; Mayer, 1966). For example, one would expect that a marital relationship in which several activities (family, sexual, social, conversational, recreational, religious) are shared would be closer, more enriching, and satisfying than one in which only a few are shared. Accordingly, the uniplex relationship would lack the quality of the multiplex relationship, and on the network level, the social network with low relationship density would tend to lack quality in its relationships generally, as opposed to the social network of high relationship density. This relationship is also obviously dependent upon other factors such as, and especially, the feelings experienced within the dyads. 33 The present study is designed to determine whether quality varies between the social networks of the schizophrenic and the normal as measured by the uniplex and multiplex relationship and relationship density. Functional Indegree and Outdegree Functional indegree and outdegree are function—related variables which, by definition, identify the degree of affective and instrumen- tal support given and received by the focal person in the social network. Functional indegree and outdegree would appear to be affected by the influences of social isolation and withdrawal, respectively. Therefore, in terms of support, one would suspect that the schizophrenic person would tend to receive and give less within the context of the social network than the normal person. However, the additional factor of size would affect this relationship in that with the reduced size of the schizophrenic's social network, more per person (more functional indegree) would be required to support the schizophrenic person. Due to the withdrawal, though, the schizophrenic person is still expected to give less to each network member, on the average, than the normal person. The present study is designed to determine if the degree of sup- port given and received in the social network of the schizophrenic differs from that of the normal person, which may be associated with the influences of social isolation and withdrawal as well as network size. 34 Functional Symmetry Functional symmetry is a function-related variable in social network analysis which relates to and has its meaning in the basic network concept of reciprocity. According to Hollander (1967), "interaction operates in terms of reciprocity; that is, the expecta- tion that a benefit given will be returned" (p. 207). So in many ways, the exchange or transaction can be seen as defining a relation- ship. Supporting this conceptualization, Whitten and Wolfe (1973) wrote: For network analysis, the important aspect of exchange theory, with its concept of reciprocity, is its demonstration that any exchange can forge an interpersonal link, and interpersonal links can connect individuals in series of communicative, economic, manipulative, and other types of strands. (p. 731) The degree of reciprocity in a relationship can be used to char- acterize the nature of transactions and satisfaction in a relationship. The work of Thibaut and Kelley (1959) indicated that the social exchange should be rewarding for both parties for the interaction to be satisfying and continue: this hypothesis can be used to examine the following system of classifying transactions. Sokolovsky, Cohen, Berger, and Geiger (1978) and Cohen and Sokolovsky (1978) focused on the elements of directionality and measure of support within dyadic relationships. In their system, which is defined relative to the focal person, when aid flows from the focal person to a network mem- ber, it is termed as "instrumental“; when aid flows in equal measure between the focal person and a network member, it is termed as "recip- rocal"; and when aid flows from a network member to the focal person, it is termed as "dependent." Summarizing the above, then, relationships 35 that are characterized solely by instrumental or dependent transac- tions, i.e., lacking in reciprocity, would be seen as unsatisfactory and possibly as fragile. The present study is designed to determine how the social net- works of the schizophrenic person and the normal person differ rela- tive to the concept of reciprocity and relate the differences to the degree of satisfaction and fragility in the social network. The links in the social network of the schizophrenic are expected to be characterized by the dependent transaction. Affective Indegree, Outdegree, and Symmetry Affective indegree, outdegree, and symmetry are emotion-related variables in social network analysis, associated with the influence of social isolation and withdrawal in schizophrenia in that they are related to the degree of satisfaction and closeness in relationships. Due to these two influences, it is expected that the schizophrenic person cares less for and is cared for less (less positive feelings) by network members than the normal person (low affective indegree and outdegree). Further, it is also predicted that the schizophrenic per- son feels less positively for the network members than they for him/ her (affective asymmetry), whereas the normal person and the network members tend to feel similarly toward one another (affective symmetry). The present study is designed to determine if affective indegree and outdegree are both less positive in the social networks of the schizophrenic person than of the normal person, and if affective asymmetry exists for the schizophrenic person, while affective symmetry 36 exists for the normal person. These variables, associated with the influences of social isolation and withdrawal, are related to the degree of satisfaction in the relationship. Investment Indegree, Outdegree, and Symmetry Investment indegree, outdegree, and symmetry are emotion-related variables that appear to provide the closest estimate of the degree of isolation and withdrawal of the schizophrenic person. Investment indegree within the social network of the schizophrenic may initially be expected to be lower than that of the normal, due to the phenomenon of isolation; however, considering the smaller network size of the schizophrenic, as well as the tendency to be dependent, it appears that the network members of the schizophrenic are more invested than the network members of the normal person. Investment outdegree may reflect the relative degree of withdrawal of the schizophrenic from the social network. Investment asymmetry is expected for the schizo- phrenic due to relatively large degree of withdrawal in the schizo- phrenic, especially since the network members are predicted to be in the position of providing much more support to the schizophrenic than the reverse. Notably, this investment imbalance suggests that at this point in the development and life cycle of the target sample, the role of withdrawal in the schizophrenic, endogenous influences, predominates over the role of isolation, exogenous social influences, within the psychosocial sphere. This statement certainly parallels the thought of Arieti (1974). Last, investment symmetry is predicted 37 for the social network of the normal; i.e., the emotional investment would be mutual. The present study is designed to determine how the social net- works of normal and schizophrenic persons differ relative to investment indegree, outdegree, and symmetry and further, to relate the differ- erences to the influences of isolation and withdrawal of the schizo- phrenic. Social Networks and Schizophrenia In this section, the studies exploring the influence of various components of the social network, and the associations between social network variables and psychopathology and schizophrenia, are reviewed to clarify the role of the social network in the schizophrenic dis- order. The findings of the most relevant studies are summarized and critically examined to identify weaknesses and sources of inconsis- tency. Based on the review, the need for replication is supported, and last, an alternative, corrective methodology is outlined. General Importance of the Social Network to Schizophrenia Although only a few studies have examined the direct links between social networks and the schizophrenic disorder (to be reviewed), a plethora of studies has explored the relationships between the schizo- phrenic disorder and the various components of the social network, i.e., the mother, father, family, extended family, and significant others. In this section, the impact of these components upon the schizophrenic disorder 'Hs reviewed briefly to demonstrate their 38 importance. This review is not intended to be exhaustive, but rather to identify major trends in the literature. This is the first step in supporting the contention of this research study that interper- sonal and social factors are associated with the schizophrenic dis- order. The relationship between the schizophrenic and his/her parents was an early area of focus that was concentrated on parental character- istics that tended to be associated with schizophrenic offspring. Theorists, concerned primarily with etiology, initially directed their speculations on the maternal relationship (Arieti, 1974), especiallyFYjeda Fromm-Reichmann (1948), who appeared to have had the most influence upon this movement through the development of the heuristic phrase, "schizophrenogenic mother." This type of mother was described in a totally negative way, e.g., over-protective, hos- tile, rejecting, cold, distant, inconsistent, etc. Others in the interpersonal school of thought such as Rosen (1962) and Sullivan (1953) tended to follow her lead with one result being that the mother was seen as totally responsible for the schizophrenic offspring; therefore, the mother was seen in a very negative light. The work of Lidz and his associates (see Lidz, 1973; Lidz, Cornelison, Fleck, & Terry, 1957; Lidz, Terry, & Fleck, 1958), though strongly affected by Fromm-Reichmann (1948L departed from this single-minded course by focusing on the paternal relationship with the schizophrenic offspring as well. Therefore, the father could now share the responsibility with the mother for the schizophrenic person. 39 Later developments in the research widened this circle of influ- ence to include the family as a whole. Early pioneers in family research studied the family more as a unit and developed such etiologically based concepts as pseudomutuality (Wynne, Rychoff, Day, 8 Hirsch, 1958), double bind (Bateson, Jackson, Haley, 8 Weakland, 1956), undifferentiated family-ego mass and triangulation (Bowen, 1960, 1965), and mystification (Laing, 1964). Based on the early work and theory, present investigators are focusing on specific areas such as communication (Ferreira 8 Winter, 1968; Mosher, Wild, Valcov, 8 Feinstein, 1972; Wild, Shapiro, 8 Goldenberg, 1975), interaction (Mishler 8 Waxler, 1965, 1975; Riskin 8 Faunce, 1972; Waxler 8 Mishler, 1971), role structure (Wild, Shapiro, 8 Abelin, 1977), cognition and perception (Riess, 1971), and emotional expression (Brown, Birley, 8 Wing, 1972; Leff, 1976; Vaughn 8 Leff, 1976). The results of these studies demonstrate associations between schizophrenia and family variables, yet as of the present none have been able to prove an etiological hypothesis due to the difficulties with this type of research (Reiss, 1976). Newer studies are either focusing on non- etiological hypotheses (simply associations) or attempting to inte- grate genetic hypotheses (Liem, 1980). Relationships have been found between the extended family and psychopathology, suggestive of possible relationships with the schizo- phrenic disorder, and in at least one case, a direct connection between characteristics of the extended family and schizophrenia. In 1962, Bell determined that the extended family can affect disturbed families differently than well families by supporting one side within a family 4O argument, creating further schism, by serving to stimulate conflict, by serving as a projection of family conflicts, and by becoming a competing object for support or indulgence. Cohn and Talmadge (1976) echoed this type of dynamic in a more recent clinical study. In a study of the extended family and the schizophrenic disorder, Walsh (1978) found that families that contained a schizophrenic offspring experienced the death of a grandparent more commonly than families with normal children or children with a nonschizophrenic, psychiatric disorder. Based on clinical findings, Bowen (1961) has developed a theoretical approach which is based on the impact of the extended family from a historical perspective, termed a three-generational theory. According to his approach, the psychopathology is passed through the generations via the projection of emotional immaturity, the end result being the schizophrenic person. It is interesting to note that in a more recent review and update of his theoretical propo- sitions, Bowen (1978) stated that a premature death in the family can hasten the development of schizophrenia, a thought consistent with the findings of Walsh (1978). Therefore, it appears that the char- acteristics of the extended family may have an impact upon the func- tioning of the family and quite possibly on the familial setting of the schizophrenic person. The relationship of the schizophrenic person with significant, but non-blood/marriage related, persons has been shown to have bearing upon the onset of the disorder (psychotic break), prognosis of the disorder, response to psychological and psychotropic treatment, and nature of posthospital functioning. In relation to the psychotic 41 onset, Birley and Brown (1970) and Jacobs and Myers (1976) found that some disruption in the social network of the schizophrenic person, namely a recent and stressful life event, preceded a symptomatic relapse. (See also related articles by Allisi, 1969, and Feldman 8 Schertz, 1967, which suggest that treatment may be sought due to ineffective networks.) In terms of prognosis, Strauss and Carpenter (1972, 1977) in two studies utilizing two- and five-year follow-ups found that the amount of social contact just prior to hospitalization was a key predictor of outcome: These studies confirmed the earlier work of Gittelman-Klein and Klein in 1969. Further, Kayton, Beck, and Koh (1976) found that a "favorable convalescent environment," one in which peers as well as parents or spouses "provided nonintrusive emotional support through their attitude toward the patient and through sensitively timed interpersonal contact” (p. 1270), was asso- ciated with a positive outcome. Regarding psychotherapy, clinical studies intimate that significant others in the social network may have positive impact by supporting the family (Reuveni, 1979; Speck, 1967) or substituting for the family functions (Minuchin, 1974; Minuchin, Montalvo, Guerney, Rosman, 8 Schumer, 1967). Dealing with the interface of drug and psychosocial treatment, Gunderson (1977) concluded after an exhaustive review that the interpersonal milieu of the hospital affects the need for psychotropic medication. Last, the reports of healing communities (rehabilitation centers) demon- strated how the functioning of the schizophrenic person is facili- tated by a supportive and responsive interpersonal environment (Gunderson, 1980; Mosher 8 Keith, 1980) For clinical descriptions of 42 community support programs, see Almond, 1974; Beard, Malamud, 8 Rossman, 1978; Budson 8 Jolley, 1978; Dincin, Selleck, 8 Streicker, 1978; Fairweather, Sanders, Maynard, 8 Cressler, 1969). This review also identified those who doubt seriously the efficacy of these approaches (Klein, 1980; Torrey, 1980). So, much of the literature suggests that onset, prognosis, response to treatment, and even remis- sion of the schizophrenic disorder are influenced by the nonkin sig- nificant others. In closing and in line with the conclusions of Caplan (1974), it appears that all components of the social network, i.e., family, extended family, significant nonkin, can have impact on the life of the schizophrenic, either in a protective and supportive way or in a provocative and deteriorating manner. Social Networks and Psychopathology Direct relationships have been found between the presence of psychopathology and the characteristics of social networks in three clinical studies. As reviewed by Pattison, Llamas, and Hurd (1979), Ratcliffe and Azim (1975) discovered that in comparing normals and psychiatric patients the latter were less satisfied with their per- sonal relationships, depended more on "involuntary" relationships with relatives, and exhibited a lack of voluntary or friendship relation- ships. A comparison of outpatient psychiatric patients and family practice patients by' Silberfeld (1978) indicated that the social net- works of psychiatric patients were impoverished in terms of number of relationships and time spent and closeness within these relationships. 43 Contradicting the study by Ratcliffe and Azim (1975), Silberfeld found that psychiatric patients seemed to have a greater proportion of their relationships with friends. Kleiner and Parker (1974) reported that alienation from the social network correlated positively with three measures of psychopathology. In sum, the results of these studies suggest that the type, quantity, and quality of relationships within the social network appear to be linked to psychopathology. Review of Major Studies In the following section four studies are reviewed that have explored the social network of the schizophrenic person as compared to the social network of normal/nonpsychotic controls. Each is examined in light of the major objectives of this study, namely, the identi- fication and relevance of the four major classes of social network variables: structure, content, function, and emotion. Their findings are summarized in terms of consistencies and inconsistencies. Short- comings and inherent methodological and design differences in the studies which complicate the interpretation and integration of the findings are presented in the section that follows this one. Cohen and Sokolovsky (1978) have reported on their assessment of the social network of schizophrenic persons who are living in "single room occupancy" (SRO) hotels in Manhattan, New York, away from family and kin. Three groups of tenants were identified for study according to degree of pathology: (a) SR group--schizophrenia with moderate or severe residual symptoms; (b) S group--schizophrenia with minimal or no chronic symptoms; and (c) NP group--those with no 44 known psychotic history. The population studied included both males and females, and whites and nonwhites. The data were collected through combined participant observation, logs of daily activity, extensive biographical interviewing, and the use of a "Network Profile" questionnaire. The authors distinguished between "interac- tional characteristics" of networks, the specific variables being uniplex relations, multiplex relations, and directionality (the direc- tion in which support flowed between the focal person and the network members), and "morphological features” (the specific variables being size and interconnectedness). Significant differences were found in the Cohen and Sokolovsky study (1978). In terms of structure, the results indicated that those with a nonpsychotic history had social networks twice the size of those who had a serious psychotic history (the SR group); no signifi- cant differences were found between the two psychotic groups (the S and SR groups): the total number of relations for the SR, S, and NP groups were averages of 10.3, 14.8, and 22.5, respectively. However, it was observed that a progressive increase in network size was asso- ciated with decrease in psychopathology. Further, they observed a trend, though statistically nonsignificant, toward a higher degree of interconnectedness in the less disturbed groups (the S and NP groups), indicating that the most disturbed group (the SR group) had networks that were generally less intertwined. In terms of content, significant differences were found in number of multiplex relations between the NP group and the SR group, but not between the two schizo- phrenic groups. The NP group had an average of 12.1 multiplex 45 relations, while the figures for the S and SR groups were 6.7 and 4.3, respectively. In terms of function, the authors concluded, It was found that schizophrenics with residual deficits were impaired in their ability to form instrumental relationships. Furthermore, both categories of schizophrenics engaged in significantly more dependent interactions than the NP group. (p. 551) Emotion as a social network variable was not examined. Not directly associated with the objectives of this study, they also found that rehospitalization was dependent upon the degree of psychopathology and hotel network size, the latter being more significant with the schizophrenic group with minimal or nonchronic symptoms (the 5 group), suggesting that for those without severe symptomatology of overwhelm- ing proportions the size of the social network can play a mediating role. Tolsdorf (1976) compared 10 male, hospitalized first-admission psychiatric patients and 10 male, hospitalized medical patients at a Veterans Administration Hospital. Those in the psychiatric sample were all diagnosed as schizophrenic. Data were obtained through a 66-item interview conducted by the author. The methodology entailed both quantitative and qualitative analyses. The quantitative data included structural variables, e.g., size and interconnectedness, and content and function variables, both paralleling Cohen and Sokolovsky's (1978) interactional characteristics. The perception of the social network from an emotional perspective was evaluated through the qualitative data. Significant results were also found in the Tolsdorf (1976) study, but only in relation to the content and function network variables. In terms of structure, no significant differences were found in the 46 total size of the networks, although a trend was noticed with the medical/nonpsychotic group being larger: the average network sizes of the medical and schi20phrenic groups were 37.8 and 29.8, respec- tively. No differences were found in adjacent density, the measure of interconnectedness. In relation to content variables, the medical group had a significantly higher number and proportion of multiplex relationships: the total average multiplex relationships for the medical and psychiatric groups were 16.6 and 5.4, respectively, and proportioned average multiplex relationships for the medical and psychiatric groups were .44 and .21. Further, significant differ- ences were found on relationship density: average of 1.53 for the medical group and average of 1.24 for the psychiatric group. In terms of function in the networks, the psychiatric group had fewer functional members within the social network, but these members served several functions; thus, the support was concentrated in a limited few. On the other hand, the network of the medical group was characterized by more functional people overall who provided fewer functions apiece, so the supportive functions were spread out more evenly across the network. Additionally, the psychiatric group tended to have asymmetric, dependent relationships with network members, and the medical group, symmetric or reciprocal relationships. Consider- ing a possible interaction, the author hypothesized that the psychi- atric group tended to limit their multiplex relationships to func- tional people in their network, while the medical group had multiplex relationships with nonfunctional people too; therefore, the activities of the psychiatric group were limited primarily to functional people, 47 i.e., those vnu) support them. From the quantitative data, Tolsdorf (1976) made the following interpretative statement in conclusion (Inferences regarding families examined in the study and contained in the statement below were not explored in this review as they do not pertain to the results of the present study.): In summary, the psychiatric subjects reported fewer intimate relationships with their network members in a network that was more heavily dominated by family members, where functional people were in a more controlling and dominant position, and where overall there were relatively fewer but more powerful functional people in the network. The medical subjects, on the other hand, reported more intimate relationships with more people in a network that was less dominated by family members and where functional people were on an equal standing with subject in the exchange of support, advice, and feedback. (PP. 412-413) The interpretation of the qualitative data generally suggested that members of the psychiatric group had a negative emotional perception of the helpfulness and character of their social networks, and this perception influenced their ability to seek support and utilize the resources of their networks. Members of the medical group uniformly had a positive perception of their networks, which appeared to facili- tate the seeking of support and use of resources. Pattison, deFrancisco, Wood, Frazier, and Crowder (1975) used the Psychosocial Network Inventory (described in Chapter II) to analyze the social networks of normals, neurotics (not pertinent to this studY). and psychotics. No statements were made regarding the sexual composition of the samples. The data were analyzed along five variables: (a) degree of interaction, (b) type of emotion, (c) strength of emotion, (d) instrumental base, and (9) symmetry. Except for size and a social connectedness ratio (associated with interconnectedness), the variables were not operationalized. 48 The results of the study by Pattison et a1. (1975) are suggestive of associations between social network characteristics and schizo- phrenia, but as it is a descriptive study based on impressionistic findings, no statistical validation of any kind, "statistically sig- nificant results" cannot be reported. In terms of the structure of the social networks, it was found that the normal sample was composed of 20 to 30 people whereas the psychotic sample was composed of 4 to 5 people, mostly family, so impressionistically the normal sample appears much larger than the psychotic sample. Further, using the social connectedness/unconnectedness ratio, it was determined that approximately one-half to two—thirds of the network members knew one another, while the rest did not. For the psychotic network, approximately nine-tenths of the network knew one another. So one could impressionistically conclude that the social network of the psychotic was more interconnected than those of the normal. Again, hard data were not provided on the other variables; however, it was noted from a review of the data that the relationships appeared to be consistently ambivalent and nonreciprocal. Pattison et a1. con- cluded with the following provocative comment: "In other words, the psychotic is caught in an exclusive small social matrix that binds him and fails to provide a healthy interpersonal matrix" (p. 1249). In a more recent study directed by Pattison (Pattison, Llamas, 8 Hurd, 1979), he has modified the results of his earlier research. Again in this study the sample was not described in terms of composi- tion and crucial variables were not operationalized. Furthermore, what hard data were available were not subjected to statistical 49 validation. In regard to the results, Pattison and his associates indicated that the psychotic network is composed of 10 to 12 network members, whereas the normal network is composed of approximately 25 members. Not of direct relevance to this study, he found that in line with his previous study the network of the psychotic group was populated predominantly by kin/family members. The relationships were characterized from a review of the data as totally intercon- nected, negativistic, conflictual, ambivalent, and highly asymmetric. Pattison et a1. concluded of the psychotic, "The subject is caught in and tyrannized by a collusive closed system, with few links to the larger communities of relationships" (p. 66/481). This review of the four major studies demonstrates the presence of consistencies and inconsistencies in the reported data. In terms of network size, the results of the four studies differ on the exact figure with the range of reported figures extending from 4 to approxi- mately 30; however, regardless of the average figure for network size, consistently it was found in three studies (Cohen 8 Sokolovsky, 1978; Pattison, deFrancisco, Wood, Frazier, 8 Crowder, 1975; Pattison, Llamas, 8 Hurd, 1979) that the social network of the schizophrenic person tended to be smaller than that of the normal person. In terms of intercon- nectedness, the results of the studies again vary a great deal. Tolsdorf (1976) found no differences, while Pattison et a1. (1975, 1979) reported a high level of interconnectedness and Cohen and Sokolovsky (1978) distinguished a trend indicating that the degree of interconnectedness fell significantly for the schizophrenic groups, the opposite of the previous findings of Pattison et a1. (1975, 1979). 50 In terms of multiplex relationships, the investigators who examined this phenomenon (Cohen 8 Sokolovsky, 1978; Tolsdorf, 1976) tended to agree on their basic findings and figures: fewer multiplex relations. In terms of relationship density, Tolsdorf (1976), the only investi- gator to examine this variable, found significant differences. In terms of the transaction of support within the network, the studies reach consensus in that the schizophrenic tended to form more dependent and asymmetric relationships than is true for the normal person. Tolsdorf (1976) further explored this finding, concluding that those who support the schizophrenic are also those with whom the schizo- phrenic person shares most of his activities; these supportive persons also appeared to be a limited subgroup within the larger network. In terms of the emotion variable, it is unfortunate that the investigators (Pattison, deFrancisco, Wood, Frazier, 8 Crowder, 1975; Pattison, Llamas, 8 Hurd, 1979; Tolsdorf, 1976) ink) examined this phenomenon did not use empirical measures, but their qualitative results tend to agree in essence, namely that schizophrenic persons would have a more negative view of their social network. Using only those results in which some degree of consensus was found, it appears that one can ten- tatively conclude that as compared to the normal person, the schizo- phrenic person tends to relate in a more dependent and asymmetrical fasion in a social network that is characteristically smaller, marked by fewer multiplex relations, and perceived in a negative way emo- tionally. 51 Need for Replication In reviewing the research on the social networks of schizo- phrenics, two major factors led this researcher to consider the need for replication of the previous work: (a) the importance of the research, and (b) confusion around the interpretationauulintegration of the previous findings. (Statements will be made in the final para- graph of this section as to how this study will be conducted.) First, the social network research is quite promising as it has revealed some findings which are consistent across studies, possibly shedding light upon the social factors operating in schizophrenia (and, for that matter, in other psychopathological populations). Thus, due to the potential importance of these findings, replication is essential. Second, the findings of the previous work are difficult to interpret and integrate for five basic reasons: (a) inadequate sample descriptions and differing populations, especially those factors relating to residence with family; (b) differences in conceptualiza- tion and Operationalization of variables; (c) differing conceptuali- zations of the social network; (d) inconsistencies in the reported data; and (e) importantly, a crucial methodological problem in making inappropriate inference regarding the characteristics of social net- works from unvalidated self-report. Relative to sample characteristics, Pattison et a1. (1975, 1979) did not give adequate sample characteristics. The studies of Cohen and Sokolovsky (1978) and Tolsdorf (1976) have more adequate descrip- tions of their samples, but they differ in sexual composition and especially, residential status. In relation to the latter, residential 52 status, the three studies except the one supervised by Cohen and Sokolovsky appear to have focused on schizophrenics living with family; Cohen and Sokolovsky only utilized subjects living away from families. Only Cohen and Sokolovsky acknowledge the implica- tions of this sample criterion. Last, it is interesting to specu- late that the differences in interconnectedness among the studies of Cohen and Sokolovsky and Pattison et a1. may relate to this differ- ence. Integration of the work is also difficult due to the differences in the Operationalization of interconnectedness of the social network, and vague conceptualization of the content variable. To operational- ize interconnectedness, Pattison et a1. (1975, 1979) used a social connectedness/unconnectedness ratio. Tolsdorf (1976) used adjacent density, and Cohen and Sokolovsky (1978) used density and degree, two related variables (the latter has been used to correct for the tendency for larger networks to produce low density systems). In their conceptualization of content, Tolsdorf and Cohen and Sokolovsky appear to have included distinct and differing concepts under the content category, confusing its meaning and contaminating its signifi- cance: Tolsdorf's definition of the content variable included areas that relate to roles and ways of relating within the network, in addition to areas that relate directly to activity, the apparent focus of the content category; and Cohen and Sokolovsky assessed functional properties and supportive roles as well as types of activity within their content variable. 53 Notable inconsistencies in the data are found in the size and interconnectedness of the social network, as well as other variables. (You are referred to the earlier discussion of this subject.) The procedures used to collect data suggest differing concep- tualizations of the social network which compounds the task of inte- gration of findings. Pattison et a1. (1975, 1979) used a specific network termed the psychosocial kinship system, which is composed of all those important to the subject, e.g., family members, relatives, friends, neighbors, co-workers, etc., the basic criterion being per- sonal importance to the subject. According to his personal communi- cation (Pattison, 1979, 1980), it would contain all those of psychodynannc significance,so anyone real or fantasied, or dead or alive, could be included. Referring to the earlier reviewed concep- tualizations, the psychosocial kinship system appears to be personal network (see Wolfe, 1970), subjective in nature (see Pattison, 1977), containing only the immediate or personal network level of linkages (see Hammer et al., 1978), and being a product of the first two and possibly third levels of intimacy (see Boissevain, 1974). The social network conceptualization chosen by Tolsdorf (1976, 1980), on the other hand, is much different because he focused on a much larger group of alternative persons and used a more objective model. His primary goal was to identify the largest possible group of persons available in a realistic sense to the schizophrenic person so as to advance some statements regarding the resource capabilities of the social network; therefore, personal importance would appear to play a secondary role. Of course, deceased persons would be excluded as 54 members of the social network as he conceived it. Again in relation to the reviewed conceptualizations, the social network as chosen by Tolsdorf (1980) was more objective in focus, although the subjective component was high since he relied on self-report (see Pattison, 1977), consisted of the immediate and second-order networks (see Hammer et al., 1978), may have focused on personal as well as categorical sets--an emphasis being on resource capabilities of the network-~(see Wolfe, 1970), and may have been directed on including all zones of intimacy, or at least the first four (see Boissevain, 1974). Cohen and Sokolovsky (1978) have most clearly defined their social network, basing their conceptualization on subjective and objective data; the networks were developed from participant observation, logs of daily activity, extensive biographical interviewing, and the use of a "network profile" questionnaire. Networks were broken down into those existing outside of and inside of the SRO hotel. Their con— ceptualization of the social network was based on subjective and objective perspectives (see Pattison, 1977), conceived as a personal set (see Wolfe, 1970), limited to the level of the immediate or per- sonal network (see Hammer et al., 1978), and may include those from the first four levels of intimacy (see Boissevain, 1974). Thus it is seen that each researcher has from differing perspectives developed differing conceptualizations which inhibit, but when recognized may facilitate integration of their results. For example, the differing conceptualizations used in the studies would certainly affect the figures obtained for network size and, accordingly, account for the large variability in results. 55 Last and importantly, this study is undertaken to analyze a methodological problem stemming from reliance on unsubstantiated self- report data. Pattison et a1. (1975, 1979) through an inventory, and Tolsdorf (1976) through an intensive interview, assessed the subjects' perception of their social network. They assumed that their data accurately reflected the characteristics of the social networks. As has been stated earlier, this is a dubious assumption, for their data reflect only the subjects' opinion of their networks unless otherwise proven. This was not true for the study of Cohen and Sokolovsky (1978), who used subjective and objective measures; their analysis may therefore present data closer to the "actual" status of the social network. The following steps have been taken in the present study to respond to the difficulties noted above. First, the sample is thoroughly described and delimited demographically, and specifically limited to the 18- to 40-year-old age group. Second, only subjects residing with families are included in the samples. Third, the methodology utilizes the previous sound research techniques for assessment of interconnectedness; and in relation to content, this variable is strictly and categorically defined as the set of shared activity. Fourth, to reduce confusion it is stated that the con- ceptualization of this study is that of the psychosocial kinship system (Pattison et al., 1975, 1979). And fifth, the present study is designed to corroborate the subjects' perception of their social network with the report of network members as a measure of validity, using the same assessment instrument, the Psychosocial Network 56 Inventory, Modified. Although it seems inherently inconsistent to choose an instrument focusing on subjective perceptions to investi- gate objectivity of response, it is consistent with the notion in perceptual theory that all of human existence is subjective, and as consensus is reached, the phenomenon becomes more "objective." The test then is to determine how able the normal and schizophrenic per- sons are to reach consensus with their relative social networks. Summary The major purpose of this research study is to compare the social networks of normals and schizophrenics, the goal being identifica- tion of psychosocial factors that appear to be associated with the schizophrenic disorder. The psychosocial kinship system, the particu- lar social network conceptualization used in this study, was chosen for its clinical significance. The two groups are compared along the four major classes of social network variables: (a) structure, the basic morphological characteristics; (b) content, the nature of shared activities; (c) function, the transaction of support; and (d) emotion, the experiencing of affect. A secondary purpose of this study, yet of paramount importance in the study, is to evaluate the research assumption conceptually basic to much of the previous research, that self-report data are a sufficient and accurate indicator of the actual status of the social network. Social network analysis was reviewed. Although it was found that the concept of the social network evolved as a metaphor, later 57 the concept began to be regarded as a singularly important concept with wide applicability and methodological value which has allowed for the integration of personal, social, and cultural dimensions, documenting their importance and interplay. The theoretical concepts of schizophrenic withdrawal and isola- tion were reviewed and were found to have joint and interacting impact on the social network of the schizophrenic. They represent the theoretical basis of this study. In light of the influences of schizophrenic withdrawal and isolation, the network variables were reviewed and evaluated as to their psychological and social implica- tions; based on this information, predictions were made. In terms of the structure-related variables, it appears that the schizophrenic, as contrasted with the normal, has a social network that is smaller and less interconnected, and network members that live closer and participate in more frequent contact. In terms of the content-related variables, it appears that the schizophrenic, as contrasted with the normal, has a greater proportion of relationships in which only one activity is shared, a smaller proportion of relationships in which more than one activity is shared, and overall, a relatively smaller proportion of shared activities per network member. In terms of the function-related variables, it appears that the schizophrenic, as contrasted with the normal, within interpersonal relationships with the network members receives more and provides less support. Further- more, the schizophrenic appears to generally receive more support from network members than is given in return, placing the schizophrenic in a functionally asymmetrical, nonreciprocal, and dependent position. 58 In terms of the emotion-related variables, it would appear that the schizophrenic, as contrasted with the normal, is the object of less positive (more negative), yet stronger (more emotionally invested) feelings, and has less positive (more negative), and weaker (less emotionally invested) feelings. Overall, the schizophrenic appears to have more negative feelings for and to be less invested in the network members than they in her or him, demonstrating an emotionally asymmetrical and nonreciprocal relationship with the social network, and a withdrawn and/or isolated position. The four major studies investigating the relationships between the schizophrenic disorder and social networks demonstrated consis- tencies in their findings tending to support some of the above predic- tions, as well as inconsistencies. Consistent findings in relation to the normal population compatible with the predictions included the following: (a) smaller network size for the schizophrenic; (b) a smaller proportion of relationships in which more than one activity is shared for the schizophrenic; (c) relatively more support from network members for the schizophrenic; (d) asymmetrical, nonrecipro- cal, and dependent relationships for the schizophrenic; and (e) nega- tive emotional perception of the social network for the schizophrenic. (One investigator found that the relationships were characterized by fewer activities per person within the social network of the schizo- phrenic.) Inconsistent findings were associated with the actual network sizes and interconnectedness, the former possibly related to differences in conceptualization of the social networks and the latter to differ- ences in the familial characteristics of the populations sampled. 59 The findings of the four studies were, however, difficult to interpret and integrate for five reasons: (a) inadequate sample descriptions and differing populations, (b) differences in concep- tualization of and Operationalization of variables, (c) differing conceptualizations of the social networks under study, (d) inconsis- tencies in the reported data, and (e) importantly, lack of validation of the self-report data. The present study is designed to respond to the difficulties noted in the previous research allowing for a clari- fication of the findings in this area of study. CHAPTER II METHODS Subject Selection and Characteristics General Selection Rationale Research investigating significant differences between popula- tions is usually designed to promote comparability along certain dimen- sions that could affect outcome measures. The goal is to reduce initial differences between the samples on these relevant dimensions that are unrelated to the basic distinctions between the populations; accordingly, additional precision is obtained in the statistical analysis of the data. In social science research, the influences of the following variables may be controlled: (a) age; (b) sex; (c) race; (d) marital status; (e) educational level; (f) vocational level; (9) personal economic status (PES), for the purpose of this study, an indicator of the individual's ability to be self-supportive; (h) socioeconomic status (SES), for the purpose of this study, an indicator of the family's economic level; and (i) cultural background. The following discussion presents the rationale used in deter- mining the relevance of the variables noted above and the procedures used to control for the potential untoward effects, if appropriate. Due to the impairment in the social functioning of the schizo- phrenic (see Review of Literature), the variables, educational and vocational levels, and personal economic status (PES), did not appear 60 61 appropriate for control. These variables are directly affected by the schizophrenic process, by definition. Attempting to insure comparability, for example, by matching along these three variables is to exclude a priori differences inherent in the two populations. Such "equalizing" procedures would call into question the diagnosis of the schizophrenic sample if the subjects were functional in these areas. The mental health of the normal sample would likewise be questionable if the subjects were dysfunctional in these areas. To some extent, this line of reasoning applies alsotxlthevariable,nwrita1 status, since the schizophrenic tends not to have the complex skills needed to initiate and maintain the marital union (this variable will also be considered below). Although studies have shown that the lowest socioeconomic class has a significantly higher incidence of schizophrenia (Dohrenwend 8 Dohrenwend, 1969), further exploration of the methodology and findings shows no correlation between SES, as defined in this study (the family's income level), and incidence of schizophrenia; however, what is being termed PES in this study appears to be related to inci- dence of schizophrenia (Dunham, 1965; Goldberg 8 Morrison, 1963; Hare, 1956a, 1956b). An example would be the schizophrenic who has difficulty maintaining employment (low PES), but who comes from a wealthy family (high SES); herein lies the basic distinction. Dohrenwend and Dohrenwend (1974), notably, still consider this issue unresolved. Although SES was not considered related to schizophrenia, it is a significant variable in social research of schizophrenia 62 (Myers 8 Roberts, 1959), and as such, appears an appropriate variable for control. The remaining variables of age, sex, race, and cultural background appear appropriate for control for the same reason. Two procedures were implemented which have impact on assuring compara- bility. First, the samples were limited to residents of a specified geographic locale, constraining the range of SES and differences in cultural background. Both samples were drawn solely from the north and northwest suburbs of Chicago. Second, subjects were chosen who would tend to provide a representative cross-section of the population of the designated locale, thereby allowing for the development of samples that would be reflective of the population along the above dimensions. The normal sample was obtained from volunteers found in a variety of settings, i.e., employment, residential, and religious, insuring a cross-section of the identified locale. The schizophrenic sample was also developed from a variety of settings, as no one psychiatric institution (public or private) services all strata of the locale clinically. An inherent difficulty with this type of research is that sub- jects are not strictly selected, randomly or otherwise; they volunteer. Therefore, sample characteristics cannot be rigidly controlled. Research sites can be selected that contain the appropriate popula- tion or subgroup of same for the study; however, after the qualified, potential participants are identified within the setting, they are invited to participate on a voluntary basis. Their involvement is not fixed; it is a variable. Those who eventually become subjects and follow through with the testing are a subgroup of the identified 63 original group (this process was essentially identical for both samples). Each sample, therefore, becomes a discrete entity with special characteristics that hopefully are representative of a cross- section of the population and are comparable along the salient dimen- sions of age, sex, race, SES, and cultural background, given a certain sample size. Another method to deal with the difficulty of samples that are potentially skewed along salient dimensions is to increase sample size. While it would be advantageous to have very large samples, the following practical issues made the proposed sample size goals difficult to meet. First, the voluntary nature of the procedure proved to be a significant hurdle: Although exact figures were not kept, it was calculated that approximately one-half of the schizo- phrenics asked to participate declined. Several from the schizophrenic population who refused to participate were characterized clinically as distinctly more hostile or paranoid than participating subjects. Inso- far as this subgroup was not studied, its composition was not clearly determined. Other possible influences determining the negative response may have included the potential time commitment of the interview and the instrument's exploration of the personal sphere which may have appeared threatening. In specific relation to the schizophrenic sample, it was found that securing institution approval and support for social science research was a generally difficult, complicated, and lengthy process. Furthermore, obtaining individual physician authorization for the project created lengthy delays. Legal and technical considera- tions further complicated and delayed the data gathering. Last, the 64 the corroborating network members were difficult to reach, today's mobile society possibly a factor. The potential exists, however, that as subjects volunteer for the study, the samples may become skewed along the important vari- ables mentioned above. In the event of such an occurrence, an alternate procedure exists that could theoretically be utilized to promote comparability between the samples, termed ”matching." The procedure was not chosen, based on the following rationale: Matching along the five relevant variables would probably lead to a drastic loss of subjects in both samples, reducing sample size below reasonable limits for statistical evaluation. On the other hand, one could attempt to continue searching for appropriate subjects, but consider- ing the number of variables and difficulty obtaining matchable sub- jects, the process was seen as close to impossible. Basically, though, matching as a procedure was not used because the gains in precision did not appear to justify the procedural difficulties, as the sample differences on the dependent variable were expected to be large. Furthermore, the procedures already taken to promote comparability, in concert with other measures to reduce initial differences, i.e., the selection of subjects aged 18 to 40 years and residing with mem- bers of their nuclear family or family of origin, only, reduced the hypothetical variance between the two samples to tolerable limits. Selection Criteria While the previous discussion focused on promoting comparability between the two samples on variables unrelated to the definition of the populations, the present discussion focuses on criteria to insure 65 that the samples drawn are, in fact, distinct and representative of the normal and schizophrenic populations under study. To assure the mental health of the normal sample, the subjects chosen met the fol- lowing criteria: (a) no known personal or family history of a mental illness as established by the American Psychiatric Association, Qi_gf nostic Statistical Manual of Mental Disorders, III (1980); and (b) continuing employment and/or attending school, as evidence of a functional or adaptive capacity. In the first criterion for the normal sample, family history pertains to history of those family members present in the immediate family, nuclear family, and/or family of origin. Immediate nuclear family could possibly include subject's spouse and children only; immediate family of origin could possibly include subject's parents and/or stepparents, and siblings only. Therefore, the psychiatric history of the subject's nephews or nieces, in-laws, aunts, uncles, or grandparents would not be con- sidered or pertinent. To assure that the other sample was schizo— phrenic, the subjects chosen met the following criteria: (a) history of hospitalization for a schizophrenic disorder, and (b) diagnosis of schizophrenia made in the past three years. Other selection criteria alluded to in the previous discussion relative to the issue of comparability included (a) subjects aged 18 to 40 years and (b) residence with members of their nuclear family or family of origin. Last, due to the difficulties that can be encountered communicat- ing with the schizophrenic, the following criterion was added: Those 66 participating in the study must not be presently psychotic, meaning out of touch with reality and incapable of communication. Subjects Two different groupings of subjects were involved in the two phases of the research. Considering phase two first, all subjects, a total of 35, participated within the two comparison samples: The normal and schizophrenic samples contained 18 and 17 subjects, respec- tively. Phase one contained five subjects from each sample who per- mitted the corroboration and at least four members from their social networks, a total of 46 network members. (The following statements apply to all the subjects of the study, excepting the subject/ corroborators of phase one.) According to the selection rationale, the sample characteristics of age, sex, race, and cultural background should be comparable to promote statistical precision; the data found in Table 1 indicate that such was the case in this study. The two sample distributions of age were quite similar (see Table 1). The median and standard deviation for both samples were identical, and the mean varied by only four years. The sex ratios, as presented by Table 1, were roughly comparable. Relative to race, the data on Table 1 demonstrate that the clear majority of both samples were members of the same race (Cauca- sian): Only one subject per sample was of another race. Last, it was seen that the religious background (associated with cultural heritage) of all subjects reflected the Judeo-Christian tradition; in particular, the Protestant and Catholic religions predominate clearly in the normal sample and were exclusive within the schi20phrenic sample. 67 Table 1: Sample Characteristics Groups Sample Characteristic G] Norma1 62 Schizophrenic p_ = 18 p2 = 17 Age _ Mean X = 30 7': 26 Median M4= 30 M = 30 Standard deviation §D_= 6.0 4S9 = 6.0 2% Male 8 11 Female 10 6 Race Caucasian 17 16 Black -- 1 Oriental 1 _- Marital status Single 4 13 Married 13 3 Divorced l 1 Family residence Nuclear family 14 3 Family of origin 4 14 Education Highest degree: Less HS diploma -- 3 HS diploma 4 12 Baccalaureate 8 1 Advanced degree 6 1 Summary: Mean years of schooling 16 13 Employment status Full-time 16 5 Part-time 2 -- Unemployed -- 12 Studenta l 2 Religious background Protestant 7 11 Catholic 8 6 Jewish 3 -- aThe student category overlaps with the other three. 68 Also according to the selection rationale, the sample character- istics associated with educational level, employment, personal economic status, and marital status should vary as they are related to the a priori differences in both samples, i.e., their population char- acteristics; the data in Table 1 indicate that such was the case, although the absence of random selection does not strictly permit the drawing of inferences. Relative to educational level, it appears that subjects within the schizophrenic sample predominantly tended to ter- minate their education after completion of high school. Subjects of the normal sample, however, tended to pursue and complete the bac- calaureate and more advanced degrees. Notably, when the mean years of schooling (see Table 1) were compared, the differences do not seem as large; yet it is crucial to observe that although the mean years were not so dissimilar, the number of those who actually completed the requirements for a degree were. The category of employment status reflects a priori designations in terms of sample criteria; nonethe- less, the finding is striking that only 5 of 17 members of the schizo- phrenic sample were employed at all, while all 18 normal subjects were employed either full- or part-time (see Table 1). Personal economic statusvdficfliis associated with vocational level and income was difficult to determine due to inability of most schizophrenic subjects to report their personal and family income; however, it was found that the majority of the schizophrenic subjects had held unskilled or semi-skilled jobs in their employment history and were at the time of testing largely dependent upon public aid and/or their family for financial support, whereas subjects within the normal 69 sample were in large part pursuing a career full-time in a trade, semi-professional, or professional occupation supporting themselves and their family. One could tentatively conclude that the personal economic status did vary considerably between the two groups, the normal sample having a much higher status. Last, the sample differ- ences in terms of marital status and, accordingly, type of family residence (see Table 1) were considerable. Curiously, while married subjects living with nuclear family predominated in the normal sample, single subjects residing with family of origin predominated in the schizophrenic sample. Therefore, as predicted, the subjects differed on variables associated with population characteristics. These findings support the two positions taken in the selection rationale. First, as the two samples were comparable along the vari- ables of age, sex, race, and cultural background, the relative impact on the social variables in this study is reduced, limiting the possible variance. Second, because the two samples varied on educational level, employment, personal economic status, marital status, and type of family residence, the two samples appeared basically different. In conclusion, the two samples appeared both relatively uniform internally, yet inherently different, representative of the distinct population characteristics; thus, a comparison with intelligible results appears tenable. However, in that approximately half of the schizophrenic persons refused to participate in the study, data were not obtained from a particular section of the schizophrenic population, a subgroup of unclear composition but possibly more hostile and 7O paranoid. Therefore, the results will not reflect the influence of this undefined subgroup. Instrumentation Psychosocial Network Inventory The Psychosocial Network Inventory was developed as a research instrument to explore the functioning of social networks by E. Mansell Pattison (Pattison et al., 1975). As originally devised, the subject is faced with three primary tasks. First, the subject develops a list of all people personally important to him or her. The criterion of importance has its basis in the clinical origins of the researcher and, as such, places the focus on those persons who are active in the subject's emotional life (see Chapter I). Second, the subject rates the nature and quality of the relationship with each person specified along five variables. The first variable is contact; questions define the frequency of interaction between the subject and the network mem- ber, and how close to each other they live. The second variable is emotional intensity; the strength of the feeling between the subject and the network member is assessed. The third variable is type of emotion; questions relate to how positive, negative, or mixed the feelings are. The fourth variable is instrumental base; questions relate to how one can be counted upon for concrete assistance. The fifth and final variable is degree of reciprocity; questions assessing the feelings and the instrumental base are interrelated to develop an idea of the affective and instrumental quid pro quo, i.e., give and take. In other words, the relationship is determined to be symmetri- cal or not, depending on how the feelings and supportive actions are 7) expressed between the subject and the network member. Third, the subject indicates which network members have relationships with one another (outside their relationship with the subject), providing a measure of the interconnectedness within the network. Psychosocial Network Inventony, Modified The Psychosocial Network Inventory (Pattison et al., 1975) has been modified for use in this study; the revised form, termed the Psychosocial Network Inventory, Modified (PNIM), is distinct in seven major ways. First, the PNIM (see Appendix A) was designed for use in a structured interview. The degree of structure varies depending upon the population: In this study, the degree of structure was high for the schizophrenic sample (see Appendix A: Directions: Structured Interview [2]) and low for the normal sample (see Appendix A: Directions: Structured Interview [l]). Second, the subject's selec- tion of social network members has been structured to enable a more orderly and thorough identification process (see Appendix A: Listing of Persons Important to you)- Third, the answer sheet has been designed to ease recording and facilitate computer keypunching (see Appendix A: Answer Sheet). Fourth, a response key utilizing scales has been added to insure accuracy of response within the interview (see Appendix A: Response Key [2]) or without interviewer support for the normal subject (see Appendix A: Response Key [1]). Fifth, a ques- tion has been added to assess the content-related aspects of rela- tionships, i.e., types of shared activities within the relationship (see Appendix A: item 3 on the PNIM). Sixth, as the concept of 72 reciprocity is basic to the interpretation of this instrument, the instrumental and affective quid pro quo between the focal person and the network member has been retained, yet redefined and expanded. In agreement with Pattison, the instrumental and affective aspects of relating are viewed as being supportive, thus functional to the relationship. As designed, affective functioning can be expressed as both behavioral support, i.e., physical affection (see Appendix A: items 5 and 7 on the PNIM), and verbal support (see Appendix A: items l2 and 15 on the PNIM). Furthermore, instrumental functioning can be expressed as both behavioral support, i.e., helping by doing (see Appendix A: items 6 and 13 on the PNIM), and verbal support, i.e., guidance (see Appendix A: items 4 and 11 on the PNIH). (Note: One item assesses the type of support from the focal person to the network member, while the other assesses the support from the other direction.) Seventh and quite importantly, the variables within this study are all defined operationally in terms of the items of the PNIM; there- fore, the items of the PNIM are all operationally linked conceptually to variables. The Operationalization of the variables used in this study is reviewed in the following section. Operationalization of Variables The purpose of this section is to provide an overall perspective and detailed description of the specific variables used in phase two of the study. The major areas are defined, divided, and broken down into their component parts. The variables are described thoroughly and operationalized relative to the PNIM: Important computational 73 formulas are included. (Please refer to Appendix B, Phase I: Corrob- oration, for the Operationalization of phase one; and Phase 11: Main Analysis, for a more intensive treatment in outline form of the opera- tionalization of the PNIM.) Structure-related variables. The structure-related variables convey the basic morphological characteristics of the social network. The four main structural variables are size, interconnectedness or adjacent density, distance, and frequency of contact. Size refers to the total number within the social network: the actual number of persons identified as important in the social network. Adjacent density, an index of the interconnectedness, refers to the proportion of linkages (relationships) in the social network to the total pos- sible number of linkages in the network. The formula for computing adjacent density is 2a/n(n + l) where a = the actual number of linkages in the network and n = the network size. Distance refers to the distance between the focal person and a network member in terms of location or time of travel, and is assessed through a desig- nated question (see Appendix A: item 2 on the PNIM). Frequency of contact refers to the relative frequency of contact between the focal person and a network member, and is assessed through a designated question (see Appendix A: item 1 on the PNIM). Content-related variables. The content-related variables convey aspects of the content of the relationship between the social network of normals and schizophrenics. In this study, content is strictly defined as activity. Ten content areas--literally, types of activity-- have been selected for inclusion in this study and assessed by a 74 designated question (see Appendix A: item 3 on the PNIM). These types of activities are intended to be categorical and inclusive. They are listed below with definitive examples: 1. FAMILY activities such as meals, holidays, vacations, or reunions. 2. EMPLOYMENT-related activities such as working with co-workers or supervisors. 3. ROMANTIC activities such as dating, dancing, or going out to dinner. 4. CONVERSATIONAL activities such as intimate, personal sharing or philosophical discussions. 5. SOCIAL activities such as parties, banquets, or visiting. 6. RECREATIONAL activities such as playing cards, participation in sports, or attendance at sports events. 7. FRATERNAL activities such as participation in clubs or other organizations. 8. RELIGIOUS activities such as attendance at church, synagogue, or temple. 9. POLITICAL activities such as rallies, or discussions of politics. 10. VOLUNTEER work such as service to the community, giving blood, or hospital work. The content of the relationship is assumed to be a partial index of the quality: The more varied the content, i.e., the greater num- ber of activities shared, the higher the quality of the relationship. To reflect this dimension, two types of relationships (with varying 75 implications about quality) have been chosen for study: the uniplex and the multiplex relationship. In the former, only one activity is shared in the relationship; in the latter, two or more activities are shared. Another content—related variable, relationship density, is a summary index of the quality of the relationships within the social network, actually the primary star; the formula for relationship density is Z rx/n, where r = the number of content areas (in this study r may equal 10) and n = the number of possible linkages in the primary star. Thus, relationship density is an average of the content areas of the relationships between the focal person and the social network. Function-related variables. The function-related variables reflect the transaction of support between the focal person and the social network: Function is designated as either affective verbal, affective behavioral, instrumental verbal, or instrumental behavioral support (refer to the previous section for a list of the matching items). Two items on the PNIM correspond with each one of the four designations, making a total of eight related items; one item of each pair elicits the degree of support the focal person receives; and the other, the degree of support the focal person provides. The three function-related variables are functional indegree, functional outdegree, and functional symmetry. Functional indegree indicates the degree of instrumental and affective support that the focal person is receiving (items 5, ll, 13, and 15). Functional out- degree indicates the degree of instrumental and affective support 76 that the focal person is providing to a network member (items 4, 6, 7, and 12). For one relationship, both are computed by summing the degree of support, whether given or received by the focal person, across the items assessing the four dimensions. The functional indegree and outdegree for a network are computed by summing across the network and dividing by the total network size. Functional symmetry is a function-related variable that assesses the balance of support in relationships in the social network. Three cases are noted. When the functional indegree (FI) and functional outdegree (F0) are equal, i.e., when the support is given and received in equal measure, the relationship is characterized by functional symmetry, and is termed for this study, "reciprocal." Uhen the F1 is larger than FO, i.e., when more support is given by the network member to the focal person, the relationship is functionally asymmetrical, and is termed relative to the focal person, "dependent," When the F0 is larger than the FI, i.e., when the focal person is giving more than the network member, the relationship is again asymmetrical, and termed relative to the focal person, "supportive.” Assessments of functional symmetry are made within the social networks of normals and schizo- phrenics in terms of the total social networks. Emotion-related variables. Assessment of emotions is broken down into two categories: types of feelings and strength of feelings. The variables used to examine the type of emotion are affective indegree, affective outdegree, and affective symmetry. Affective indegree indicates the type of feelings expressed by a member for the focal person as perceived by the focal person. The range extends 77 from all positive to all negative feelings. The index for one rela- tionship is equivalent to the answer of the designated item (see Appendix A: item 8 on the PNIM). The affective indegree for the social network is a summing across the network for that item divided by the size of the network. Affective outdegree indicates the type of feelings experienced by the focal person for a member of the social network. The range extends from all negative to all positive feel- ings. The index for one relationship is also equivalent to the answer of one designated item (see Appendix A: item 14 on the PNIM). The total affective indegree is a summing for that item divided by n. Affective symmetry exists when the type of emotion between the focal person and the network member is identical, i.e., when affective indegree (AI) = affective outdegree (AO). Affective asymmetry exists when the type of emotion between the focal person and the network member varies, i.e., when AI f A0. The variables used to examine the strength of emotion are invest- ment indegree, investment outdegree, and investment symmetry. Invest- ment indegree reflects the strength of feelings (emotional investment) experienced by the network member for the focal person as perceived by the focal person. The range extends from weak to very strong feelings. The index for one relationship is equivalent to the answer to one designated item (see Appendix A: item 9 on the PNIM). The investment indegree for the social network is a summing across the network for that item divided by n. Investment outdegree reflects the strength of feelings (emotional investment) experienced by the focal person for a network member. The range extends from weak to 78 very strong feelings. The index is also equivalent to the answer to one designated item (see Appendix A: item 10 on the PNIM). The total investment outdegree is also a summing across the network divided by n. Investment symmetry exists when the emotional investment experienced by the focal person and the network member is equal. Investment asym- metry exists when their emotional investment is different. An exception. Certain types of network members will not be included in the data analysis due to the importance and relevance of reciprocity in the analysis of the PNIM and the necessity of cor- roborated self-report. The analysis and interpretation of the results of the PNIM are predicated on the assumption that the assessed rela- tionships can be reciprocal in all respects: The presence or absence of reciprocity in relationships has certain meanings that are central to the purpose of this study (see chapter I). In order to be able to make proper interpretations of the results, only those network members capable of reciprocal arrangements will be included in the data analy- sis. Also, network members must be capable of reporting on their relationship with the focal person. Furthermore, they must actually be present physically. For these reasons, the deceased and/or fan- tasied network members will not be included in the data analysis. Consent Procedures Two sets of consent procedures have been developed to accommodate to the intrinsically different characteristics of the two samples, the normal and the schizophrenic, and the environments in which they were identified. The term "schizophrenia" is a psychiatric diagnosis that denotes a certain type of mental illness; as such, it is subject 79 to regulation and strict definition. Those facilities responsible for the housing and/or treatment of the schizophrenic are ethically and legally charged to protect the identity of the schi20phrenic and maintain the confidentiality of the schizophrenic's records. Excep- tions are defined legally, must be justificable, and are subject to stringent safeguards. Accordingly, the identification of the schizo- phrenic sample and the acquisition of informed consent for the study are difficult and complex procedurally and involve ethical and legal considerations, the focus explicitly being the protection of the wel- fare of the schizophrenic. The term "normal,” used to describe the other sample, is neither a psychiatric diagnosis nor is subject to regulation; therefore, the consent procedures are relatively simple and straightforward, although the focus remains protection of the subjects' welfare. Testing Procedures Normal and Schizophrenic Samples A set of parallel, but differing, testing procedures was designed for the normal and schizophrenic samples. Each set constituted a structured interview. Both sets of procedures contained seven inter- view phases, one of which might not be used depending on whether data corroboration was permitted by the subject. Four of these phases were required for the completion of the Psychosocial Network Inventory, Modified. Each phase corresponded to the completion of a primary task within the interview. The primary tasks of the seven phases were identical between the two samples. However, the manner in which the 80 primary tasks were to be accomplished differed in varying degrees, based on the characteristics of each sample. Most prominently, group testing and unassisted completion of the inventory (once directions were understood) were permitted for the normal subjects, due to their superior functioning capacity; on the other hand, all schizophrenic subjects were tested individually and in private to respond to their particular personal needs, lower functioning capacity, and issues of confidentiality and privacy: In this way, the interviewer could pro- vide immediate and continuing assistance and direction, and demon- strate overtly a respect for the privacy of the schizophrenic subject. Last, to facilitate the completion of the two types of structured interviews, directions were drafted for the use of the interviewer (see Appendix A: Directions: Structured Interview [1], designed for the normal sample; and Directions: Structured Interview [2], designed for the schizophrenic sample). Phase 1. The primary task of this phase of the structured inter- view was to provide an adequate explanation of the study to the sub- ject. Two forms were prepared, one for each sample (see Appendix A: Explanation of the Research Study [1], designed for the normal sample; and Explanation of the Research Study [2], designed for the schizo- phrenic sample). The appropriate forms were read to subjects of both samples; subjects were encouraged to ask their questions immediately. Members of both samples were asked if they understood the explanation of the study. A lack of understanding or misunderstanding was explored when either appeared. Also, each subject was asked specifically about the corroboration aspect/option of the study to assure comprehension. Bl If necessary, the letter to be sent to corroborating network members (see Appendix A) was shown to clarify any questions, especially those pertaining to confidentiality and privacy. Phase 2. The primary task of this phase was to obtain the informed consent of the subject to participate in the study and, when appropriate, to permit the contact of network members, randomly selected, the purpose being corroboration of self-report data. Two consent forms were prepared for use in this phase, one with additional statements relating to the corroboration option for use with subjects giving their approval for corroboration and from whom it was desired by the researcher (see Appendix A: Statement of Informed Consent [1]), and another for use when corroboration was neither approved by the subject nor desired by the researcher (see Appendix A: Statement of Informed Consent [2]). The researcher made the request for the cor- roboration option of every subject in both samples who appeared interested and open until the desired percentage of respondents was reached. After the appr0priate form was placed in front of the subject/s, the t0p of form (1) or form (2) in entirety was read by the interviewer. When the interviewer was confident that the explana- tion of the study and of the rights of the subject was understood by the subject/s, the interviewer asked the subject/s to sign and date the form, all interested in further information about the study after its completion to make a mark by their name. For those subjects interested in the corroboration option, the relevant statements found on the lower portion of form (l) were read and explained by the 82 interviewer. At this point, the request was made for the subject/s to sign and date this portion of the consent form. Once the consent forms had been signed and dated, the four basic steps in the study were outlined and the data collection began. The four basic steps were as follows: (a) completing the General Infor- mation Sheet, (b) listing persons in the network, (c) assessing rela- tionships, and (d) indicating the relationships among the persons named. Phase 3. The primary task of this phase was the completion of the General Information Sheet (see Appendix A). The interviewer encouraged the normal subjects to complete this form without assistance; however, if this wasn't a successful approach with any normal subjects, then the interviewer would ask the questions and complete the form, using the form as a prompter. For the schizophrenic sample, the interviewer asked the questions, using the form as a prompter, and recorded the responses for the subject. Phase 4. The primary task of this phase was the development of a list of all persons who were presently important in the life of the subjects. Two forms were designed for use in this phase: the answer sheet (see Appendix A) and a list of persons who might be potentially important to the subject to be used as a prompter, insuring a complete list (see Appendix A: Listing of Persons Important to You). All sub- jects were encouraged to use their own definition of importance. Additionally, subjects from the normal sample were invited to fill out the names, as well as other identifying information (sex, length of relationship, and type of relationship) on their answer sheet. The 83 normal subjects were also requested to circle the names of persons named who are deceased. The normal subjects could also exercise an option to complete the list following the interview, as long as a partial list of a minimum of six names was completed in the inter- viewer's presence to assure a thorough understanding of the task and accuracy. The interviewer filled out the names and identifiers of the complete social network for the schizophrenic subjects. Phase 5. The primary task of this phase was the assessment of the relationships, identified in the social network, through the use of the Psychosocial Network Inventory, Modified (see Appendix A). Two other forms contained the three scales for answering items 4 through 15 on the Psychosocial Network Inventory, Modified (PNIM), one for each sample (see Appendix A: Response Key [1], designed for the normal sample; and Response Key [2], designed for the schizophrenic sample). After the total list of important people was developed for both samples or, at least, a partial list of six for the normal sample, the assessment of relationships began within the structured interview. The interviewer initiated the assessment by taking the first person identified in chronological order and asking the first three questions on the PNIM. For both samples the interviewer read these questions; however, the normal sample was encouraged to fill in the blanks with the interviewer's assistance and the schizophrenic sample only needed to respond verbally to the questions while the interviewer marked the answer sheet. After these were completed for both samples for the first person, the rest of the questions on page two of the PNIM and the appropriate response key were presented to both samples. The 84 scales were described as a continuum, all along which answers could be selected. Response Key (1) for the normal sample was numbered one through nine to correspond to the answer code, to permit answers between the modal points, and to facilitate unassisted completion once the directions were understood. Response Key (2), identical to the former response key except for the numbering, was presented to the schizophrenic sample with the explanation that they could identify their answer on any point along the scale, including the five points offered for guidance. Once this had been fully explained, items 4 through 15 were asked of both samples. It was then added that all questions must be completed for all identified persons. The schizo- phrenic sample with the interviewer's assistance then continued assessing the relationships until all were completed. In some cases, the schizophrenic subjects opted to answer items one through three on all persons before continuing to the second page: Such was permitted (likewise, some normals opted for this alternative). Also, the schizophrenic subjects were offered breaks in the testing to renew their interest and concentration. The normal sample either completed all assessments of the relationships during the interview or finished at least two complete assessments of the relationships if they opted to complete the form later, given their more difficult timetables and scheduling. Phase 6. The primary task of this phase was the assessment of the degree of connectedness among the network members: The procedure was identical for both samples. The interviewer assisted all sub- jects to identify ongoing relationships between the network members. 85 To qualify for an ongoing relationship, it was required that both persons must know each other and_have some kind of relationship with each other outside their relationship with the subject. The assigned chronological numbers of those identified as having a relationship with the selected person were written in the right hand column of the answer sheet designated "Connections." After all of the identi- fied persons had been assessed for network connections, the structured interview terminated unless the subject had been asked and permitted the corroboration phase. Phase 7. The primary task of this phase was to identify through random selection the network members who were to be contacted to corroborate the self-report of the subject. One form was used for this phase to assist the interviewer in random selection of the corrobo- rating members (see Appendix A: Selected Network Members). On this form, the size of the identified network was associated with five numbers of random selection which designate those identified. All subjects were informed which five network members were chosen through the randomizing process. Once fully informed, the subjects were free to rescind their approval of this phase. Only two schizophrenic sub- jects so decided at this point. The names, addresses, and phone numbers were collected on all five members identified for corrobora- tion; however, when an identified member met one of the criteria for exclusion ([a] deceased and [b] a fantasied relationship), alternate choices were made randomly on the spot. This phase completed the structured interview. With the interview ended, the subjects were thanked for their time, effort, and interest in the research. 86 Corroborating Network Members Contact and examination of the corroborating network members, those identified by random selection in phase seven of the testing procedures for the subjects, involved a three-phase effort. Phase 1. During this phase, the corroborating members were con- tacted by phone. In the conversation they were informed of the nature and purpose of the contact and the extent of their involvement, asked if they were interested in participating in this research, and if so, to supply or confirm their mailing address. A few declined immediately at this point and others failed to respond after the mailing. A few others were not contacted first by phone as the numbers were not known. Phase 2. During this phase, the corroborating members who were interested in or open to considering participation or unreachable by phone were mailed the following forms, as well as a self-addressed stamped envelope for response: Corroborating Member Letter (see Appendix A), Statement of Informed Consent (2) (see Appendix A), and Response Key (1) (see Appendix A). In the letter the nature and pur- pose of the contact and focus of the study were presented, safeguards to confidentiality and privacy mentioned, and the request was made that if they would be willing to participate in the study to sign, date, and forward the enclosed consent form in the self-addressed envelope. If there were any questions, a 24-hour phone number was included. Last, a response key was enclosed to facilitate answering of the questions from the PNIM. 87 Phase 3. This phase began once the consent form was received in the mail from the cooperating network member; however, when the corroborating members seemed unduly late in returning the form, follow-up calls were made. With the consent forms returned, the cor- roborating members were again contacted by phone and asked questions about their relationship with the subject and their knowledge of other important relationships. In relation to the former, they were asked all of the questions on the PNIM as it applied to their relationship with the subject. All answers were written on a standard answer sheet which was designated for corroborators of a certain subject: Each corroborator was assigned the number given to him/her by the subject. In relation to the latter, they were asked how many people they knew whom they would consider as personally important to the subject, i.e., the network cluster. The answer to this question, the size of the network cluster, was written under "SUM" on the right portion of the answer sheet, the same place designated for the sum portion of the subject's response. With this final answer recorded, this third and final phase is completed: At least four corroborating members were tested in this fashion, although five were initially identified. All corroborators were informed that, upon their request, they would be forwarded more complete information about the study and an overview of the results. Last, all were thanked for their interest and participation. 88 Risk/Benefit Analysis An examination of the nature and design of the study suggested the presence of potential social and psychological risks to the subjects; physical, legal, and economic risks were not posed. Potential social risks were associated with the request that some subjects relinquish their anonymity to provide access to their social network for further study of the social relationships. The risk appeared to relate to possible misinterpretations by the contacted network members of (a) the subject‘s motive in identifying them and (b) the reason for the subject's participation in the study. The social risk of misinterpretation appeared to be largely dependent upon the degree of vagueness inherent in the explanation given to the contacted network member. To minimize this possibility, every effort was made to develop a clear, direct, precise, and unambig- uous explanation. However, this safeguard is one-sided in the sense that it can only act to increase the clarity of the statement; it cannot be assumed to control for idiosyncratic interpretations or misuse of the disclosure of the subject's participation by the contacted network member. Potential psychological risks related to the use and effect of the Psychosocial Network Inventory, Modified (PNIM). The use of all psychological tests is accompanied by potential risks, and the same is true for the PNIM. The primary risk is the generation of psycho- logical conflicts, and resulting discomfort/dysfunction, previously controlled by the subject's defense mechanisms. This reaction could occur in either group, but it is more likely with the schi20phrenics; 89 their coping abilities and defenses are much less controlled and integrated, by definition. However, the type of test used in this study is a highly structured, rather straightforward inventory tapping primarily conscious levels, possibly the least threatening of all psychological test forms; projective tests, on the other hand, tap much deeper levels of the subject's psyche and would, therefore, be much more likely to uncover hidden conflict and provoke an untoward reaction. The psychological risks were lessened through the choice of a multiple-choice, structured test (see above); however, if such risks materialized, plans were made to encourage the schizophrenic-~who, by the way, was tested in a psychiatric setting--to consult with his/her primary therapist and/or sign a release so that the reaction could be reported to appropriate staff. If the reaction was considerable, plans were made to report it immediately so that facility staff could act to intervene. If difficulties arose with a member of the normal group, plans were made to refer him or her to the local mental health center. Confidentiality was assured through (a) a coding procedure, (b) locked records, and (c) destruction of all identifying information after no longer necessary. Last, the study was designed to be of benefit to the subject, the profession, and society in general. Through the administration of the PNIM, the subject might develop insights into the processes and dynamics operating in his/her social network and perhaps, discover the extent of available social support. Gains within the professional 90 realm include the following: (a) determination of the validity and usefulness of self-report scales in social network analysis, clarify- ing the value of previous contributions to the field who based their work on self-report; (b) greater insight in the psychosocial function- ing of the schizophrenic relative to the normal subject; and (c) recom- mendations regarding the psychosocial management and treatment of the schi20phrenic disorder. Society, in general, could be profited by the knowledge as used by the profession. University Authorization Following the dissertation committee approval of the research proposal on January 25, 1980, the University Committee on Research Involving Human Subjects (UCRIHS) requested and reviewed the research proposal and supporting materials focusing on the rights and welfare of human subjects (see Appendix C), as mandated by the National Research Act, Public Law 93-348, Section 474(a). Following their review, Henry E. Bredeck, Chairman, UCRIHS, notified this researcher that the committee had approved the project on April 7, 1980. Research Questions This section has been included in the chapter as well as the section, Null Hypotheses, to provide the reader with an organizing schema, a mind set, with which to conceptualize the intent or goals of the study, and to grasp the extensive nature of the null hypotheses; the Null Hypotheses section is lengthy and detailed, and yields slowly to understanding without such a guide. 91 The purpose of the study was to compare the social networks of normals and schizophrenics along four major classes of variables: Structure, the dimension reflecting the morphological characteristics of the network; Content, reflecting the sharing of activities within the network; Function, reflecting the exchange of support within the network; and Emotion, reflecting the experience of emotion within the network. However, before the analysis of the social networks of nor— mals and schizophrenics can be more fully understood, the self—report of the subjects on their social networks must be corroborated with the report of at least four network members to determine the degree of agreement. This constitutes phase one of the analysis. In rela- tionship to this determination, the following research question was posited (stage one of the analysis within phase one): How does the self-report of normals and schizophrenics corroborate with the self- report of identified network members/corroborators on the joint rela- tionship along these variables: 1. Structure, specifically size of the network cluster, distance, and frequency of contact; Content, specifically the number of content areas; Function, specifically functional indegree and outdegree; and Emotion, specifically affective indegree and outdegree, and investment indegree and outdegree? One further question is posited (stage two of the analysis within phase one): Are the differences between the subjects and corroborators significant between the normal and schizophrenic samples? In relation to the stated purpose of the study, the following groups of research questions are posited in phase two of the analysis: 92 1. In terms of structure, how do the social networks of normals and schizophrenics differ relative to size, interconnected- ness, distance, and frequency of contact? Given the differ- ences, what do the interrelationships among the variables suggest about the structure of the social networks? 2. In terms of content, how do the social networks of normals and schizophrenics differ in proportion of uniplex and multi- plex relationships, and in relationship density? Given the differences, what do the interrelationships among the vari- ables suggest about the content of the social networks? 3. In terms of function, how do the social networks of normals and schizophrenics differ in functional indegree, functional outdegree, and functional symmetry? Given the differences, what do the interrelationships among the variables suggest about the function of the social networks? 4. In terms of emotion, how do the social networks of normals and schizophrenics differ in affective indegree, affective outdegree, affective symmetry, investment indegree, investment outdegree, and investment symmetry? Given the differences, what do the interrelationships among the variables suggest about the emotional dimensions of the social networks? Last, given the differences in the above four classes of variables, what can be concluded about the overall functioning of the social net- works of normals and schizophrenics? Null Hypotheses Phase One Stage one. The following null hypotheses relate to the first stage of the analysis in phase one, the corroboration of the self- report of the normal and schizophrenic samples with selected members of their social network. A statement of the major null hypothesis of stage one and phase one outlines the major intent of this stage of the analysis and precedes the testable null hypotheses associated with the classes of social network variables for the normal and schizo- phrenic samples: structure, content, function, and emotion. These 93 following hypotheses are written in multivariate form, excepting the hypotheses associated with the class of variable, content. Both con- tain a univariate statement. The numbered variables within the null hypotheses correspond to subordinate, univariate null hypotheses: The coded designation of the univariate hypothesis retains the short- hand symbol of the multivariate hypothesis, adding only the variable number separated by a dash from the subscript.

Univariate hypotheses corresponding to the variables: Hofe/s-lO; Hofe/s-l3' and Hofe/s-l6' Research Design and Analysis Phase One The focus of the research design and analysis of phase one in the study was the corroboration of self-report. Two stages of the research were planned to investigate this focus. Both are described below. Stage one. In the first stage, a comparative group design was used for each sample to determine if the self-report data were ade- quately corroborated by network members within the two samples. To set up this type of design, the self-report of five subjects in each sample was contrasted with the self-report of at least four, if not 102 five, members of their social networks on the joint relationship, and average difference scores were computed for each subject relative to the network members. These scores were compared to the zero vector. This design was characterized by one fixed independent variable, termed group differences. It has two levels, termed group of average difference scores and group of zero differences. Further- more, the design has 10 dependent variables, grouped by major class (see Figure 1). Cell size equals five. In a sense, the group of average difference scores associated with the two samples were each compared to the average difference scores of the "ideal" group. The data analysis was conducted by using three multivariate tests and one univariate test for each sample. The major hypotheses cor- responding to the three major classes of variables (structure, func- tion, and emotion) were analyzed through the use of multivariate analysis of variance tests. The goal of these multivariate procedures was to consider each class of variable separately, yet its component variables jointly, while avoiding inflated alpha levels. Each multi- variate test was examined at the p_= .10 level, chosen due to the low degrees of freedom (gf_= 4, l). Univariate tests were designed to follow if the multivariate test was significant, using an approximate, partitioned alpha level, divided by the number of dependent variables. The partitioned alpha levels of the structure-related, function- related, and emotion-related variables are .03, .05, and .025, respec- tively. The major hypothesis, corresponding to the class of variable, content, was analyzed through the use of a univariate analysis of variance, examined at the p_= .10 level. .uwcmcnaongum new _msco: .Qsocm some Low name ugoawcuwpmm we cowumgonogcou mo mwmx_mcm mg» Low .mco mmmpm .mco mmmgn Low :mwmmu gucmmmmm .P «gnaw; m mmcmmupzo ucmsumm>cH mmcmmucF pamEumm>cH mmcmmuuzo w>wpum¥m< wmcmmucw a>vpuacc< ceases“ mmmeupzo Pecowpuczd 103 mmgmmucw chowpocau cowpuczd women ucmpcou mo consaz pcmpcoo pompcou mo xucmzcmcm wucmamwo m u.m memz—u xLome: mo mem mgspuaegm mmucmcmwwwo AuwcmL580ngum co FmELozv mmmpu an mmcoum mesmemwmwo mm mpgm cm cmam ocmN mo asogu mmmgm>< we asocw _a . > p u o mmucwgmwwwo Azocw ”anmwgm> pcwucmammmm nwxwd 104 Stage two. In the second stage, a comparative group design was used to determine if the two samples were significantly different in relation to the corroboration of self-report. This design was char- acterized by one fixed independent variable, type of average differ- ence scores, with two levels, normal and schizophrenic. Furthermore, the design has 10 dependent variables, grouped by the four major classes of variables (see Figure 2). Cell size equals five. The data analysis was conducted by using three multivariate tests and one univariate test. The major hypotheses corresponding to the three major classes of variables (structure, function, and emotion) were analyzed through the use of multivariate analysis of variance tests. As in stage one, the goal of these multivariate procedures was to consider each cflass of variable separately, yet its variables jointly, while avoiding inflated alpha levels. Each multivariate was examined at the p_= .10 level, chosen due to the low degrees of freedom (g:_= 4, l). Univariate tests were designed to follow if the multivariate test was significant, also using approximate, partitioned alpha levels: The alpha levels are identical to those of stage one. Phase Two The focus of the research design and analysis of phase two in the study was the main comparison of social network characteristics between the two samples. Two stages of the research were planned to investigate this focus. Both are described below. Stage one. In the first stage, a comparative group design was used to determine if the two samples were significantly different 105 mud mud ewesem ewcegseewwcem ewesem weswez meeeem meeeeewwwe emece>< we emxw "eweewwe> peeeceeeecw eexww .euee “Loeweuwwmm cw meeeecewwwe eeeem we mwmxweee esp Lew .ezp emepm .ece emece Lew :mwmee neweemem meemeeuee weeseme>CH eecmeecw peeEume>cw ememeepee e>wpeeww< emgmmecw m>wpeeww< eewmeeuee Pecewpeceu mecmeecw Fecewpecau meeee “cmpeee we geese: pueucee we zeceeemgu museumwe gmpmewe geezem: we mem .N mcemwu :eweesm :ewpecew pampeeo eezuezeum mmewu xe mmweewwe> uceecmeme 106 along the social network variables that can be compared directly. This excludes those dealing with symmetry. This design was char- acterized by one fixed independent variable, type of sample, with two levels, normal and schizophrenic. Furthermore, the design has 13 dependent variables (see Figure 3). Although groupings by major class of variable were developed in the previous phase of analysis, this stage was not so designed as the emphasis at this point was placed on the optimum efficiency of the statistical test as opposed to concep- tual grouping. Also the possible degrees of freedom permitted this procedure. The data analysis was conducted by using one multivariate test. All 13 dependent variables, associated with the four major classes of variables, were analyzed through the use of a multivariate analysis of variance. This statistical test was examined at the p_= .05 level, chosen as an appropriate level of significance due to the high degree of freedom (gf_= l, 33). Univariate tests were designed to follow if the multivariate test was significant, using an approximate, parti- tioned alpha level to avoid an inflated alpha. The partitioned alpha level for the univariate tests, if needed, was set at p_= .005. This value is roughly equivalent to the alpha level of the multivariate test divided by the number of dependent variables. Stage two. In the second stage, a comparative group design was used to determine if symmetry within the two major classes of vari- ables, function and emotion, exists within the two samples. To develop the design, difference scores were computed between the measures of functional, affective, and investment outdegree and indegree for 107 .xeeessxm mewueeexe .mmweewwe> xeezee: weweem wwe mcewe meecm -wewwwe eeeem we cemwweeeee ewes we» Lew .mce mmepm .e2p emcee Lew cmwmee :egemmmm w_ u.m e.

This design was char- acterized by one fixed independent variable, group differences, with two levels, group of difference scores and group of zero differences: Furthermore, the design had three dependent variables (see Figure 4). The data analysis was conducted by using one multivariate test for each sample. Each statistical test was examined at the p_= .05 level, due to the high degrees of freedom ([3, 15] and [3, 14] for the normal and schi20phrenic samples, respectively). Univariate tests were designed to follow if the multivariate test was significant, using an approximate, partitioned alpha level. The partitioned alpha level for the univariate tests, if needed, was set at p_= .015. This value is roughly equivalent to the alpha level of the multivariate test divided by the number of dependent variables. m Subject selection was designed to promote comparability along those dimensions that affect outcome, as well as to insure the iden- tification of appropriate subjects from both normal and schizophrenic populations. In relation Unthe former goal, the promotion of com- parability, it was determined that steps be taken to control for age, sex, race, socioeconomic status, and cultural background, but not for educational and vocational levels, marital status, and personal economic status. In regard to the latter goal, criteria were estab- lished, all of which had to be met, for a person to qualify for member— ship in one of the two samples. A review of the characteristics of both samples indicated that both goals were essentially met.

The primary assessment instrument, the Psychosocial Network Inventory, Modified (PNIM), as its name suggests, was adapted from an inventory developed by E. Mansell Pattison (Pattison et al., 1975). As originally devised, the instrument presented the examinee with the three tasks of developing a list of personally important persons, rating the nature and quality of the relationships in this social net- work, and finally, noting the groups of persons who have relationships in common. The new instrument developed for this study, the PNIM, retains much of the content and form of the earlier inventory; however, seven improvements were made. First, it was revised as a structured inventory, responsive to the characteristics of the target populations. Second, the subject's selection of social network members was struc- tured to insure a more orderly and thorough identification process. Third, the answer sheet was designed to ease recording and facilitate computer keypunching. Fourth, a response key was added to insure accuracy of response within the interview. Fifth, a question was added to assess the content-related aspects of relationships. Sixth, the questions associated with the supportive and emotional give-and- take within relationships, i.e., reciprocity, were designed to reflect the verbal and behavioral dimensions, as well. Seventh, the items of the PNIM were all conceptually and operationally linked to the 111 dependent variables in this study; the Operationalization of the variables was reviewed. Consent procedures were developed to accommodate to the intrin- sically different characteristics of the two samples and the settings in which they were identified. Although the procedures relating to the schizophrenic, as opposed to the normal, were more complex due to ethical and legal considerations, the focus remained on the pro- tection of the subjects' welfare. Separate testing procedures were also developed for both samples and for corroborating network members; however, the normal and schizo- phrenic subjects were all faced with seven phases of testing as follows: (a) explanation of the study, (b) presentation and signing of the consent forms, (c) completion of the demographic data, (d) development of the list of personally important persons, (e) assess— ment of relationships with the PNIM, (f) assessment of the intercon- nectedness, and (9) selection of the corroborating network members. Three phases were involved in the contact and examination of corrobo- rating network members as follows: (a) initial contact including exploration of interest and confirmation of demographic data, (b) mail- ing of appropriate forms, and (c) second contact for the assessment of the relationship with the focal person. A risk/benefit analysis was undertaken, determining the presence of potential social and psychological risks to the subjects, but on the other hand, potential benefits to the subject, the professional community, and to society. The potential social risks related to the possible misinterpretation by the corroborating network members of 112 the subject's motive in identifying them and participation in the study. Clarification in the explanation to the corroborating network member was considered the primary and only safeguard. The psychologi- cal risk related to the use of the PNIM in possibly provoking an untoward reaction; however, the risk was deemed low due to the highly structured and straightforward nature of the PNIM. Finally, the benefits were determined to outweigh the possible risks, especially since safeguards were planned in case problems appeared. Considering the methods so articulated of the research study, the University Committee on Research Involving Human Subjects approved this project on April 7, 1980. The methodology of the research study was directed toward two interrelated goals, the corroboration of self- report data of social network variables within both samples and the main comparison between the two samples along the social network variables. Two research phases were designed to correspond to the two goals: Two stages were required foreach phase. Research ques- tions and null hypotheses were developed as well for both stages of both phases. In stage one of phase one, the self-report data of both groups, broken down into 10 variables, were contrasted with the self- report of the corroborating network members on the joint relationship. Average difference scores were computed and compared relative to the zero vector, using a comparative group design. For both samples, three multivariate analysis of variance statistical tests, examined at the p_= .10 level, with optional post hoc univariate tests, using partitioned alpha levels, were used to analyze those dependent vari- ables associated with the major classes of variables, structure, 113 function, and emotion. One univariate analysis of variance, examined at the p_= .10 level, was used to analyze the content-related dependent variable. In stage two of phase one, the average difference scores of both samples were compared to determine if the two groups were sig- nificantly different in terms of degree of corroboration of self-report, using a comparative group design. Three multivariate analysis of variance statistical tests, examined at the p_= .10 level, with optional post hoc univariate tests, using partitioned alpha levels, were used to analyze those dependent variables associated with the major classes of variables, structure, function, and emotion. One univariate analysis of variance, examined at the p_= .10 level, was used to analyze the content-related dependent variable. In stage one of phase two, the main comparison relative to the social network variables between the two samples was implemented by comparing along 13 dependent variables, using a comparative group design. One multi- variate analysis of variance statistical test, examined at the p = .05 level, was used to analyze these 13 variables simultaneously: Group- ing by major class was not as important conceptually as was efficiency of the statistical test. The partitioned alpha level for the post hoc univariate tests was set at p_= .005. In stage two of phase two, the focus was on symmetry within the two major classes of variables, function and emotion. Difference scores between the measures of func- tional, affective, and investment outdegree and indegree were com- puted in both samples and were compared to the zero vector, using a comparative group design. For each sample, one multivariate test, 114 examined at the p_= .05 level, was used to analyze the three dependent variables. The partitioned alpha level for the post hoc univariate analysis of variance tests was set at p_= .015. CHAPTER III RESULTS The purpose of this chapter is the presentation of the statis- tical results. For clarity, the material is organized by the various stages and phases of the analysis. Prior to the description of the results, a synopsis of the focus and analysis of each stage is pre- sented. Only significant findings are presented in this chapter; however, in the following chapter, suggestive, though nonsignificant, findings will be explored to determine their relevance for future research. Results of Phase One: Corroboration of Self-Report Stage One The focus of stage one of phase one was the corroboration of the self-report of the normal and schizophrenic samples with selected members of their social networks. Four major hypotheses were developed for each sample, corresponding to the four major classes of social network variables. The 10 dependent variables were grouped by class within these hypotheses. Using a comparative group design, the major hypotheses were analyzed through the use of three multi- variate analysis of variance (MANOVA) statistical tests and one uni- variate analysis of variance (ANOVA) statistical test for each sample. Post hoc univariate statistical tests were planned to follow 115 116 when appropriate. The results of the analysis, summarized in Tables 2, 3, and 4, follow below.

Corroboration within the normal sample. Significant differences were found to exist between the self-report of the subjects of the normal sample and their corroborators along all four classes of social network variables. In terms of the major null hypothesis associated with structure (Holn)’ the MANOVA indicated that significant differ- ences in self-report exist between normal subjects and corroborators, 117 i.e., a lack of corroboration, £_(3, 2) = 10.83, p_< .10 (see Table 2); however, no significant differences were found in the univariate post hoc analyses of the three structure-related variables: (a) size of network cluster, (b) distance, and (c) frequency of contact (see Table 3). In terms of the major null hypothesis associated with con- tent (HOZn’ equivalent to H02n-4)’ the ANOVA indicated that signifi- cant differences in self-report exist between normal subjects and corroborators, f_(l, 4) = 23.06, p_< .10 (see Table 2). The specific content-related variable was the number of content areas. In terms of the major null hypothesis associated with function (Ho3n), the MANOVA indicated that significant differences in self-report exist between normal subjects and corroborators, f_(2, 3) = 42.91, p.< .10 (see Table 2). The analysis of the univariate null hypotheses yielded significant findings for both function-related variables, functional indegree and functional outdegree, the ANOVA results being f_(l, 4) = 67.94, p_< .05 for Ho and f_(l, 4) = 34.20, p.< .05 for Ho 3n-5 3n-6’ respectively (see Table 3). In terms of the major null hypothesis associated with emotion (Ho4n), the MANOVA indicated that significant differences in self-report exist between normal subjects and cor- roborators, f (4, l) = 103.11, p_< .10 (see Table 2). The analysis of the univariate null hypotheses yielded significant findings for three of the four emotion-related variables, affective indegree, investment indegree, and investment outdegree, the ANOVA results being f (1, 4) = 36.00, p_ < .025 for Ho4n_7, E_(l, 4) = 33.68, p_< .025 for Ho4n_9, and f_(l, 4) = 22.50, p_< .025 for Ho4n_]0, respectively (see Table 3). So, in summary, it appears that the self-report of normal 118 subjects was lacking in corroboration generally along the four major classes of social network variables, i.e., structure, content, func- tion, and emotion, and specifically, along the dependent variables of number of content areas, functional indegree, functional outdegree, affective indegree, investment indegree, and investment outdegree.

Significant dif- ferences were found to exist between the self-report of the subjects of the schi20phrenic sample and their corroborators along three of the four classes of social network variables, specifically structure, content, and function; the finding relative to emotion was not sig- nificant. In terms of the major null hypothesis associated with structure (H013), the MANOVA indicated that significant differences in self-report exist between schizophrenic subjects and corroborators, i.e., a lack of corroboration, £_(3, 2) = 61.00, p_< .10 (see Table 2); significant differences relative to self-report were also found in all three structure-related variables: (a) size of network cluster, f (l, 4) = 31.34, p_< .03 for Ho (b) distance, F_(l, 4) = 12.25, ls-l’ p_< .03 for Ho]S_2; and (c) frequency of contact, F_(l, 4) = 36.00, p_< .03 for Ho]s_3 (see Table 4.) In terms of the major null hypothesis associated with content (H025, equivalent to H025-4)’ the ANOVA indicated that significant differences in self-report exist between schizophrenic subjects and corroborators, E_(l, 4) = 125.00, p_< .10 (see Table 2). The specific content-related variable was the number of content areas. In terms of the major null hypothesis asso- ciated with function (H035), the MANOVA indicated that significant differences exist between schizophrenic subjects and corroborators, f_(2, 3) = 50.96, p_< .10 (see Table 2). The analysis of the uni- variate null hypotheses yielded significant findings for both function- related variables, functional indegree and functional outdegree, the ANOVA results being F_(l, 4) = 21.05, p_< .05 for Ho3s_5 and f_(l, 4) = 120.92, p_< .05 for ”035-6 (see Table 4). The MANOVA investigating 120 the major null hypothesis associated with emotion (H045) failed to reach significance (see Table 2). In summary, it appears that the self-report of schizophrenic subjects was lacking in corroboration generally along three of the four major classes of social network variables, i.e., structure, content, and function, and specifically, along the dependent variables of size of network cluster, distance, frequency of contact, number of content areas, functional indegree, and functional outdegree.

Four major hypotheses were developed, corresponding to the four major classes of social network variables. The 10 dependent variables were grouped by class within these hypotheses. Using a comparative group design, the major hypotheses were analyzed through the use of three MANOVA statistical tests and one univariate ANOVA statistical test. Post hoc univariate statistical tests were planned to follow when appropriate. The results of the analysis, summarized in Tables 5 and 6, follow below. Significant differences were found to exist in the degree of corroboration of self-report between the two samples along two major classes of social network variables, including content and emotion; the findings for structure and function were not significant. In terms of the major null hypothesis associated with content (Hoc), the ANOVA indicated that significant differences in the degree of cor- roboration exist between the two samples, E (l, 8) = 8.96, p_< .10 (see Table 5). The specific content-related variable was the number of content areas. A review of the approximate confidence intervals suggests that the differences between subjects and corroborators were higher for the schizophrenic sample. In terms of the major null hypothesis associated with emotion (Hoe), the MANOVA indicated that significant differences in the degree of corroboration exist between the two samples, f_(4, 5) = 3.64, p_< .10 (see Table 5). The analy- sis of the univariate null hypotheses yielded significant findings 122 for only one of the four emotion-related variables, investment indegree, the ANOVA results being f_(l, 8) = 10.00, p_< .025 for Hoe_9 (see Table 6). A review of the approximate confidence intervals suggests that the differences between subjects and corroborators were higher for the schizophrenic sample. In summary, it appears that significant differences exist in the degree of corroboration between the two samples along the two major classes of social network variables, i.e., content and emotion, and specifically, along the dependent variables, number of content areas and investment indegree; in both cases, the degree of difference between subjects and corroborators was higher for the schi20phrenic sample.

Results of Phase Two: Comparison Between the Social Networks of Normals and Schizophrenics Stage One The focus of stage one of phase two was the main comparison between the social networks of the normal and schizophrenic samples. Using a comparative group design, 13 of the 16 dependent variables associated with the four major classes of variables were analyzed through a MANOVA statistical test. Post hoc univariate statistical tests were planned to follow, if appropriate. The results of the analysis, summarized in Table 7, follow below. Significant differences were found to exist between the normal and schizophrenic samples when the social network variables were analyzed altogether; however, post hoc procedures revealed that the 124 Table 7: Univariate Tests of Significance for the Null Hypotheses in Stage One of Phase Two: Main Comparison Between the Social Networks of Normals and Schizophrenics.

The MANOVA analyzing the comparison between the two samples along the 13 dependent variables yielded the following: F_(l3, 21) = 6.55, p <.05. (The actual significance of the ffvalue was a striking p_= .00008.) Post hoc findings between the two samples yielded only one significant finding for the structure-related dependent variable, size of network, f_(l, 33) = 45.86, p_< .005 for Ho (see Table 7). _.._.._, ._ 1 s-l In terms of size of network, the normal group had a mean of 36.23 with a standard deviation of 13.31, and the schizophrenic group had a mean of 12.65 and a standard deviation of 5.61. Stage Two The focus of stage two was the assessment of function-related and emotion-related symmetry within the two samples. Accordingly, func- tional, affective, and investment symmetry were grouped into a major null hypothesis for each sample. The difference scores were computed for the measures of outdegree and indegree for the three dependent variables, and the data were analyzed through a MANOVA statistical test. Post hoc univariate statistical tests were planned if approp- riate. The results of the analysis, summarized in Tables 8 and 9, follow below. Symmetry within the normal sample. In terms of the normal sample, no significant differences were found to exist between the measures of functional, affective, and investment outdegree and indegree when the variables were analyzed simultaneously; therefore, support was not found to reject symmetry as significant differences 126 between the measures of indegree and outdegree would mean that symmetry for the normal sample does not exist (see Table 8.)

Symmetry within the schizophrenic sample. In terms of the schizophrenic sample, significant differences were found to exist between the measures of functional, affective, and investment out- degree and indegree when the variables were analyzed simultaneously; therefore, the existence of symmetry was disproven for the multi- variate hypothesis. Significant univariate findings were found rela- tive to functional symmetry. In terms of the major null hypothesis associated with the schizophrenic sample (Hofe/s)’ the MANOVA indicated that significant differences exist in the three dependent measures of outdegree and indegree within the schizophrenic sample, f_(3, 14) = 10.91, p_< .05 (see Table 8). The analysis of the univariate null hypotheses yielded significant findings for only one dependent vari- able, functional symmetry, the ANOVA results being F_(1, 16) = 15.58, p_< .015 for Hofe/s-lO (see Table 9); therefore, functional symmetry was disproven,iandaffective and investment symmetry were not 127 rejected. A review of the approximate confidence intervals for the results related to functional symmetry indicated that functional indegree was significantly larger than functional outdegree for the schizophrenic sample.

Summary The focus of stage one of phase one was the corroboration of the self-report of the normal and schizophrenic samples with selected members of their social networks. As presented in Table 10, signifi- cant differences were found to exist between the self—report of the subjects and their corroborators in the normal sample along all four classes of social network variables and in the schizophrenic sample along three of the four classes of variables: structure, content, and function.

In terms of the content-related dependent vari- able, number of content areas, significant differences were found in both samples. In terms of the function-related dependent variables, functional indegree and outdegree, significant differences were again found in both samples. In terms of the emotion-related dependent variables, significant differences were found in the normal sample for affective indegree, and investment indegree and outdegree. The focus of stage two of phase one was the comparison between the normal and schizophrenic samples in terms of the corroboration of self-report. As presented in Table 11, significant differences were found to exist in the degree of corroboration of self-report between the two samples along two major classes of social network variables, including content and emotion; the findings for structure and function were not significant. The two samples varied signifi- cantly along (a) number of content areas and (b) investment indegree, variables related to content and emotion, respectively. Finally, the degree of difference between subjects and corroborators was higher for the schizophrenic sample. The focus of stage one of phase two was the main comparison between the social networks of the normal and schizophrenic samples. Significant differences were found to exist between the normal and schizophrenic samples when the dependent variables were analyzed simultaneously; however, as presented in Table 12, post hoc procedures 130 revealed that the differences were significant only for one dependent variable, size of social network. In terms of size of network, the normal group had a mean of 36.23 with a standard deviation of 13.31, and the schizophrenic group had a mean of 12.65 and a standard devia- tion of 5.61.

As presented in Table 13, significant differences were found to exist between the measures of functional, affective, and investment out- degree and indegree (when the variables were analyzed simultaneously) in the schizophrenic sample, but not in the normal sample. Essen- tially, though, functional, affective, and investment symmetry were not disproven for the normal sample. In terms of the schizophrenic sample, significant differences were associated with functional symmetry, supporting functional asymmetry. In this case, functional indegree was found to be significantly larger than functional out- degree. Furthermore, affective and investment symmetry were not rejected for the schizophrenic sample. 133 .mpwemew peeewwwcmwm ll >< .mpwzmew uceewwwcmwmcez 11 O o zeweesxm gemEpme>cw o acueeexm e>weeeww< x xeuesexm Fecewuecew x o xwuesezm eeeeewu eweewceerzem weseez ewceeceercem weawez <>ez< <>ezwuwmee ww< e>wpwmee zwpmez eexwe xwwezee peee< e>wuemec xwpmez e>wuemec __< + + + + + .m m m w e m e m N w meewum >Le> meetum eueceeez ewwz gee: + + + + + .m m w w o m a m N w xwuceeeeww >Lm> :eewo meewmeeee eEem co awewem __e we pez + + + + + .m Awe wee emzeamme 184 e>wpwmee ww< e>wpwmee xwpmez eexwe awweeee useeq e>wpemec xwumez e>wpemme ww< + + + + + .m meeeem xwe> meeeum meeteeez ewwz xeez + + + + + .m xwuceeeeew xte> :eewo mcewmeeee eeem co xmeem wwe we pez + + + + + .m Ame wee mmzeamme 185 SELECTED NETWORK MEMBERS Size of Identified Network Numbers of Network Members for Contact 1 ----------------------------------- 1 2 ----------------------------------- l, 2 3 ----------------------------------- l, 2, 3 4 ----------------------------------- l, 2, 3, 4 5 ----------------------------------- l, 2, 3, 4, 5 6 ----------------------------------- 2, 3, 4, 5, 6 7 ----------------------------------- l, 2, 3, 4, 5 8 ----------------------------------- 2, 3, 4, 5, 7 9 ----------------------------------- 2, 3, 7, 8, 9 10 ----------------------------------- 2. 4, 5, 8, 9 1] ----------------------------------- 4, 5, 8, 9, 10 12 ----------------------------------- l, 2, 6, 7, 10 13 ----------------------------------- 2, 7, 8, 9, ll 14 ----------------------------------- l, 5, ll, 12, 13 15 ----------------------------------- 3, 4, 9, 12, 15 16 ................................... 5, 6, 9, ll, 13 17 ----------------------------------- l, 8, 11, l4, 17 18 ----------------------------------- l, 8, 13, 14, 16 19 ................................... 2, 7, 9, ll, 13 20 ................................... 5, 6, 9, 13, 19 21 ----------------------------------- 2, 3, 4, 7, 17 22 ................................... 6, 10, ll, 15, 16 23 ................................... 4, 6, 14, 15, 21 24 ----------------------------------- 6, 10, ll, 15, 16 25 ................................... 11, 12, 14, 15, 17 25 ................................... 5, l6, 17, 20, 21 27 ................................... l, 2, 8, 19, 20 28 ................................... l, 17, 18, 20, 22 29 ----------------------------------- 7, 8, 9, ll, 22 3o ................................... 5, 6, 19, 23, 26 31 ................................... ll, 14, 15, 21, 24 32 ................................... 4, 8, 9, 15, 24 33 ................................... 1, 7, 16, 31, 32 34 ................................... 5, 16, 20, 21, 32 35 ----------------------------------- 5, 6, 23, 26, 34 36 ----------------------------------- 12, 14, 15, 24, 33 37 ................................... 10, 15, 16, 30, 37 38 ................................... 14, 15, 24, 36, 38 3g ................................... 2, 8, 22, 36, 37 4O ----------------------------------- 4, 18, 25, 32, 34 41 ----------------------------------- 1, l6, 18, 25, 30 42 ................................... 9, 12, 15, 20, 23 43 ................................... 13, 24, 35, 38, 4O 44 ................................... 4, 15, 17, 22, 38 186 Size of Identified Network Numbers of Network Members for Contact 45 ---------------------------------- 3, 10, 15, 20, 24 46 ---------------------------------- 2, 3, 9, 15, 32 47 ---------------------------------- 2, 7, 13, 15, 31 48 ---------------------------------- 4, 6, 21, 42, 44 49 ---------------------------------- 3, 9, 15, 19, 22 50 .................................. 4, 9, 24, 46, 48 APPENDIX B OPERATIONALIZATION OF VARIABLES 187 188 PHASE I: CORROBORATION STRUCTURE-RELATED VARIABLES l. VARIABLE: Size of network cluster DEFINITION: The size of the network cluster is that number of persons that are known jointly by the focal person (the subject) and by the network member/corroborator who are considered important by the focal person. INDEX: XCSy and XCCy .KEY: szy = The size of the network cluster as determined by the subject for a certain network member/corroborator. In the notation used in this phase, the prefixes and suffixes are used as coordinates, not as mathematical or statistical symbols. The "x" in the prefix designates the figure is one estimated by the focal person (the sub- ject). The "y” designates the number given to the corroborator as written on the answer sheet. For instance, in an example we could write 10SCs3’ meaning that for the schizophrenic subject, code #lOS, we have the size of the network cluster estimated by the subject rela- tive to the network member/corroborator, #3. If the subject was a nor- mal with the same code number, we would have lONCs3' xCCy = The size of the network cluster as determined by the corroborator relative to the focal person (the subject). The "x" in the prefix designates the code number given to the subject (the focal person, not the corroborator). The "c" in the suffix designates that the figure is one estimated by the corroborator. The "y" designates the number given to the corroborator as written on the answer sheet. 189 In our example, we would write lOSCc3’ meaning that for the schizo- phrenic subject, code #1OS, we have the size of the network cluster estimated by the network member/corroborator whose number is #3. RELATIONSHIP TO INVENTORY: NA RELATIONSHIP TO ANSWER SHEET: Five corroborators were identified on the subject's answer sheet; the responses of each corroborator were written on the ”corroborator" answer sheet, designated by the number given to them by the focal person.

The proportion varies between .00 and 1.00. , a 2a KEY: a the actual number of linkages in the network. N the network size (n) plus the focal person--n + 1. RELATIONSHIP TO INVENTORY: NA RELATIONSHIP TO ANSWER SHEET: The actual number of linkages in the network, "a," is computed by first summing the sizes of the net- work clusters (found under the SUM column of the answer sheet) across 197 all network members, designated xCS , dividing this total figure by y two, and last, adding network size. The formula is as follows: n :l a 2 iil XCSy + n. 3. VARIABLE: Distance DEFINITION: Distance refers to the average distance between the focal person and a network member in terms of location or time of travel. INDEX: d/n 1 ”M: .i 5E1; d = the degree of distance between the focal person and network member, as assessed on the inventory. RELATIONSHIP TO INVENTORY: "d” is assessed through item #2. RELATIONSHIP TO ANSWER SHEET: Locate the #2 column on the answer sheet; a = l, b = 2, c = 3, d = 4, and e = 5: the lower the value, the closer to the focal person the member lives. The numerator of the index would be the sum of the #2 column. 4. VARIABLE: Frequency of contact DEFINITION: Frequency of contact refers to the average frequency of contact between the focal person and a network member. INDEX: f/n 1 "M: i yey; f = the frequency of contact for an identified person in the network. 198 RELATIONSHIP TO INVENTORY: "f" is assessed through item #1 in the inventory. RELATIONSHIP TO THE ANSWER SHEET: To find ”f," locate the co1umn under #1 on the answer sheet; a = l, b = 2, c = 3, d = 4, and e = 5: the lower the value, the more frequent the contact. The numerator of the index would be the sum of the #1 column. CONTENT—RELATED VARIABLES 5. VARIABLE: Proportion of uniplex relationships DEFINITION: In the uniplex relationship, only one type of activity is shared in the relationship. The index is a proportion. INDEX: u/n KEY: u = the number of uniplex relationships in the social net- work of one subject. RELATIONSHIP TO INVENTORY: ”u" is assessed by item #3. RELATIONSHIP TO ANSWER SHEET: On item #3 the type and number of activities shared in a relationship are noted. If only one activity is checked for a relationship, then the identified relationship is uniplex. 6. VARIABLE: Proportion of multiplex relationships DEFINITION: In the multiplex relationship, more than one activity is shared in the relationship. The index is a proportion. INQEX; m/n 5E1; m = the number of multiplex relationships in the social network of one subject. RELATIONSHIP TO INVENTORY: "m" is assessed by item #3. 199 RELATIONSHIP TO ANSWER SHEET: If more than one type of activity is checked for a relationship under #3 on the answer sheet, then the relationship is multiplex. 7.

INDEX: r/n 1 11M: 1' KEY: r = the number of content areas checked for one person in the network. RELATIONSHIP TO INVENTORY: (Also a part of item #3) RELATIONSHIP TO ANSWER SHEET: To find "r," locate the k—column under item #3, "SUMMARY"; each line contains the sum of the checked content areas. The grand total of this column would be numerator of the index. FUNCTION-RELATED VARIABLES 8. VARIABLE: Functional indegree DEFINITION: Functional indegree indicates the degree of support that the focal person is receiving. INDEX: i q/n 1 "MD KEY; q = sum of support that the focal person is receiving from one network member as assessed by four items (5, ll, 13, 15), each on a scale from 1 to 9.

RELATIONSHIP TO ANSWER SHEET: To obtain "q" for one network member, add the responses from items 5, ll, 13, and 15. According to the index, this would be done for every individual network member, the grand total being divided by "n"; however, an easier method would be to add the columns under 5, ll, 13, and 15 and divide the result grand total by "n.” 9. VARIABLE: Functional outdegree DEFINITION: Functional outdegree indicates the degree of support that the focal person is providing others. INDEX: p/n 1 "M: i KEY: p = sum of support that the focal person is providing one other network member as assessed by four items (4, 6, 7, 12), each on a scale from 1 to 9.

Recent attempts to study its psychosocial aspects have utilized a new method of study from the field of sociology, "social network analysis." The investigator in the present study will attempt to replicate the work of these recent studies by comparing the social networks of nor- mals and schizophrenics; however, in the initial stage of the study, the investigator will test an assumption methodologically basic to these studies-~that the subjects' self-report is a sufficient and accurate indicator of the functioning of the social network. If this assumption is proven as valid, then the comparison--the focus of the second stage of the study--will be carried out using the self-report data. If not, then the comparison will be carried out as possible. The social networks of normals and schi20phrenics will be com- pared along four major variables pertaining to social relationships: structure, content, function, and emotion. The structural variables convey the basic morphological characteristics of the social network. The content variables convey aspects of the content of the social relationships, i.e., the types of activities. The function variables reflect the transaction of support. And last, the emotion variables assess the experiencing of affect. Subject Populations Sample of Normals A group of individuals will be identified to represent a normal population who meet the following criteria: (a) residence with 209 nuclear family or family of origin; (b) age ranging between 21 and 40 years; and (c) no personal or family history of a psychiatric disorder for two generations. From this group, a sample of 20 will be randomly selected for inclusion in this study. Sample of Schizophrenics A group of individuals will be identified who have a history of hospitalization for a schizophrenic disorder, and who meet the fol- lowing additional criteria: (a) residence with nuclear family or family of origin; (b) age ranging between 21 and 40 years; (c) not presently psychotic, meaning not out of touch with reality and capable of communication; and (d) diagnosis of schizophrenia made within the past 3 years. Selection Rationale Both groups will be selected for reasons of comparison and contrast, for without this, one is unable to establish a meaningful perspective. Obtaining informed consent is not foreseen as a problem with the sample of normals, but it may arise with the sample of schizophrenics. As can be seen in the consent procedures, everything is being done to fully inform the schizophrenic subject of his/her rights and alterna- tives. When this information cannot be understood, then the subject will not be included in the study as they have not met the third cri- terion mentioned above. This decision will be a judgment made by the researcher. 210 Risk/Benefit Analysis An examination of the nature and design of the study suggests the presence of potential social and psychological risks; physical, legal, and economic risks are not posed. Potential social risks are associated with the request that some subjects relinquish their anonymity to provide access to their social network for further study of the social relationships. The risk appears to relate to possible misinterpretations by the contacted network members of (a) the subject's motive in identifying them and (b) the reason for the subject's participation in the study. The social risk of misinterpretation appears to be largely dependent upon the degree of vagueness inherent in the explanation given to the contacted network member. To minimize this possibility, every effort has been made to develop a clear, direct, precise, and unambiguous explanation. However, this safeguard is one-sided in the sense that it can only act to increase the clarity of the statement; it cannot be assumed to control for idiosyncratic interpretations or misuse of the disclosure of the subject's participation by the con- tacted network member. Potential psychological risks relate to the use and effect of the Psychosocial Network Inventory, Modified (PNIM). The use of all psychological tests is accompanied by potential risks, and the same is true for the PNIM. The primary risk is the generation of psychologi- cal conflicts, and resulting discomfort/dysfunction, previously con- trolled by the subject's defense mechanisms. This reaction could occur in either group, but it is more likely with the schizophrenics; 211 their coping abilities and defenses are much less controlled and integrated, by definition. However, the type of test used in this study is a highly structured, rather straightforward inventory tapping primarily conscious levels, possibly the least threatening of all psychological test forms; projective tests, on the other hand, tap much deeper levels of the subject's psyche and would, therefore, be much more likely to uncover hidden conflict and provoke an untoward reaction. The psychological risks have been lessened through the choice of an objective and structured test (see above); however, if such risks materialize, the schizophrenic-—who will, by the way, be tested in a psychiatric setting--will be encouraged to consult with his/her pri- mary therapist and/or sign a release so that the reaction can be reported to appropriate staff. If the reaction is considerable, every effort will be made to report it immediately so that facility staff can act to intervene. If difficulties arise with a member of the normal group, he/she will be referred to the local mental health center. Confidentiality is assured through (a) a coding procedure, (b) locked records, and (c) destruction of all identifying information after such is no longer necessary. It is hoped that the study will be of benefit to the subject, the profession, and society in general. Through the administration of the PNIM, the subject may develop insights into the processes and dynamics operating in his/her social network and perhaps discover the extent of available social support. Gains within the professional 212 realm include the following: (a) determination of the validity and usefulness of self-report scales in social network analysis, clarify- ing the value of previous contributions to the field who based their work on self-report; (b) greater insight in the psycho-social func- tioning of the schizophrenic relative to the normal subject; and (c) recommendations regarding the psycho-social management and treatment of schizophrenia. Society, in general, may be profited by the knowledge as used by the profession. Consent Procedures Two sets of consent procedures have been developed to accommodate to the intrinsically different characteristics of the two samples, the normal and the schizophrenic, and the environments in which they will be identified. The term schizophrenia is a psychiatric diagnosis that denotes a certain type of mental illness; as such, it is subject to regulation and strict definition. Those facilities responsible for the housing and/or treatment of the schizophrenic are ethically and legally charged to protect the identity of the schizophrenic and to maintain the confidentiality of the schizophrenics' records. Excep- tions are defined legally, must be justifiable, and are subject to stringent safeguards. Accordingly, the identification of the schizo- phrenic sample and the acquisition of informed consent for the study are difficult and complex procedurally and involve ethical and legal considerations, the focus explicitly being the protection of the wel- fare of the schizophrenic. The term normal, used to describe the other sample, is neither a psychiatric diagnosis nor is subject to 213 regulation; therefore, the consent procedures are relatively simple and straightforward, although the focus remains protection of the subjects' welfare. The consent procedures for the normal sample will be described first. The sample of normal subjects will be chosen from groups assumed to contain "normal" members; those selected for participation in the study must meet the requirements for inclusion. The purpose and nature of the study will be described to the potential subject (see Explanation of the Research Study [1]), and if the potential subject meets the requirements and agrees to participate in the study, then an informed consent to participate in the study will be obtained in writing (see Statement of Informed Consent [1]). If the subject is involved in stage one of the study where corroboration of the data is required, then a release to notify others in the subject's network will also be obtained (see bottom of Statement of Informed Consent [1]). Those identified by the subject will be contacted by phone, informed of the reason for the phone call and nature of the study, and asked for their consent to participate in the study. A letter describ- ing the study (see Corroborating Member Letter Form) and an informed consent form (see Statement of Informed Consent [2]) will be sent by mail with a self-addressed stamped envelope enclosed. When the con- sent form is returned, the person-~identified by the subject--will be questioned as to the relationship with the subject either in person or over the phone. The examination of the schizophrenic sample may take place in a day treatment/hospital program or an inpatient unit of a ”mental health 214 facility" or "licensed private hospital" (terms in quotation marks are defined by Illinois statute). To secure permission for the run- ning of the study, a research request will be submitted for approval to the research director and/or committee of the facility. If the request is approved, the procedure to identify the sample and gain the consent forms would proceed as follows: First, a designee of the research director and/or committee will identify those schizophrenics within the facility who meet the requirements for inclusion in the study. Second, a group will be selected randomly from the original identified number. After they have been informed of the nature and purpose of the study (to be determined by the facility), a release of information (see Release of Information) which conforms to Illinois statute will be obtained from those schizophrenics potentially willing to participate in the study, allowing their identity, age, diagnosis, and residential status to be released to the researcher. In a meeting with the researcher, the potential subjects will be informed as to the reasons for their initial selection, and the nature and purpose of the study (see Explanation of the Research Study [2]). If the poten- tial subject agrees to participate in the study, then a consent form to participate in the study will be obtained in writing (see Statement of Informed Consent [1]). If the subject is involved in stage one of the study where corroboration of the data is required, then a release to notify others in the subject's network will also be obtained (see bottom of Statement. of Infbrmed Consent [1]). Those identified by the subject will be contacted by phone, informed of the reason for the phone call and nature of the study, and asked for their consent 215 to participate in the study. A letter describing the study (see Corroborating Member Letter Form) and an informed consent form (see Statement of Informed Consent [2]) will be sent by mail with a self- addressed stamped envelope enclosed. When the consent form is returned, the person-~identified by the subject--will be questioned as to his/her relationship with the subject either in person or over the phone. 216 Explanation of the Research Study (1) The purpose of the research study in which you are being asked to participate is to examine one's social network, that is to say, the social relationships one has with family, relatives, friends, co-workers, and others.

(Date) (Witness) 222 Testing Procedure The Pattison Psychosocial Network Inventory, Modified (PNIM) for interviewing, will be pilot tested and refined as necessary before being used in this study. For the study, the PNIM will be adminis- tered to all subjects within a period of two months. Administration will take place in a setting familiar to the subject. At the administration, the examiner will make an introductory statement explaining the purpose of the interview and obtain an informed consent in writing. The subject will be presented with the General Information Sheet; the examiner will answer questions and guide as needed to insure accuracy and completeness. A three-step process now begins. Step one entails the listing of all “important" persons in the subject's social network. The examiner will record the responses. An interview guide for the examiner, designating types of possible relationships, will be used to insure the development of a complete network. Step one ends when all names of those in the subject's network have been obtained. Step two involves the assessing of persons named along the items of the PNIM. The PNIM item guide will, at this point, be placed in front of the subject. The examiner will interview using the PNIM as a visual device to key the subject and otherwise structure the interview. For step three, the subject will be asked to determine which persons in the social network know each other, i.e., have some type of relationship with each other, outside their relationship with the subject. After the administration of the PNIM is completed, the subject and the examiner will identify a minimum of four key network members 223 (when corroborating information is required): two in the family; one, a friend; and another, a co-worker. Permission will be obtained to contact these four network members by phone, inform them of the nature of the study, and enlist their participation. The interview may be conducted by phone or in person, after a consent form has been signed and received. Three steps ensue during the corroborating interview. First, demographic data will be gathered. Second, the corroborator will be asked to list persons by first name and initial, known to be important to the subject, and briefly explain why. Last, the relationship between the corroborator and the subject will be assessed along the items of the PNIM. Corroborating data will be gathered until an adequate sample is obtained to test for concordance of results. 10. 224 PSYCHOSOCIAL NETWORK INVENTORY, MODIFIED GENERAL INFORMATION Age . 2. Sex: Male .
