Schizophrenia in adolescence

The emergence of schizophrenic psychoses during middle and late adolescence poses the question of how adolescence as a developmental stage is related to the emergence of severe psychopathology. This paper examines several possible explanations for adolescence as the beginning of the high-risk age, particularly for the schizophrenias. After discussing the nature of adolescence as distinguished from puberty, and then considering the nature of schizophrenia, we report some data from a long-range study of young adult psychiatric patients, both schizophrenic and nonschizophrenic. Our data support the idea that serious psychopathology—not only schizophrenia—occurs in a setting of poor competence in a variety of crucial skills which include the social, intellectual, and physical realms. The demands made on adolescents by societal expectations for independence and role establishment summon a variety of competencies. Where these competencies are dysfunctional, societal demands strain an already vulnerable youth, and potentiate disorganization.This work is supported in part by Public Health Service grants MH-05519, MH-18991, and MH-19477.This research is part of a program investigating schizophrenia which is being conducted jointly by the Psychosomatic and Psychiatric Institute of Michael Reese Hospital, the Department of Psychiatry, Pritzker School of Medicine, University of Chicago, and the Illinois State Psychiatric Institute.Received his Ph.D. in psychology from the University of Kansas.

The incongruous achiever in adolescence

The authors wished to study some of the internal psychological dynamics of achievement in a nonpatient identified high school population. Questionnaires were administered to the Grade 13 students and their parents in a large high school. A number of students whose achievement and educational plans were not congruous with their general background were selected for interview. The findings suggest that a wide variety of ages and developmental stages can be discerned as critical points in the development of a student's attitude toward higher education. These students have many values in common, and their values appear related to a positive or negative identification with parental values. The students themselves show a wide range of personality integration. They relate in a special way to a wide variety of teachers' personalities.Received M.D. from University of Alberta, Edmonton, in 1969 and completed specialty training in psychiatry at University of Toronto in 1974.

Social support and self-esteem in adolescence

This study assessed contingencies in the effect of social support from parents and friends on adolescent self-esteem. Questionnaires were administered to 76 Israeli adolescents regarding self-esteem, stressful life events, and perceived level of support from mother, father, and friends. Maternal support had a strong effect on self-esteem. Aid from friends was influential primarily when that of mothers was absent. Paternal support had little effect, once other support sources were controlled. Despite the negative influence of stress on self-esteem, support and stress had no interactive effects. These findings, consistent with attachment theory and social provision theories, were contrary to cross-pressure or separate world models of peer/parent influence.He received his doctorate in Educational Psychology from University of California at Los Angeles.

Deviant behavior and self-enhancement in adolescence

The hypothesis that “among initially high self-derogation subjects deviant response patterns (alcohol and drug abuse, delinquent patterns, etc.) are related to subsequent decreases in self-derogation” was tested with data from a longitudinal survey study of adolescents. Among higher and lower socioeconomic status (SES) males initially high self-derogation subjects who adopted (relative to those who did not adopt) any of several deviant patterns manifested significantly greater subsequent base-free decreases in self-derogation. For higher SES females only narcotics use (and among lower SES females no deviant pattern) was significantly related to subsequent decrease in self-derogation. Together with collateral data, these results indicated that where the deviant patterns were compatible with valued social roles and the subjects were able to defend against negative responses by others (but not under mutually exclusive conditions), deviant patterns functioned to reduce self-rejecting feelings among initially highly self-derogating subjects.     

Ego identity formation in middle adolescence

Assumed determinants of ego identity were investigated in this study using sophomore, junior, and senior high school males and females. Subjects were administered the Marcia Ego Identity Status Scale and measures of sex-role identification, personality development, psychological functioning, self-concept, and parental socialization practices. Data analyses, using a median split on identity score, showed that high-identity adolescents obtained more positive scores on sex-role identification, personality development, psychological adjustment, and self-concept than low-identity adolescents. Socialization practices also differed for the two groups. The sex differences which emerged were congruent with the identity literature. Overall, the data supported Erikson's theory of ego identity development.This study was funded by Grant No. 791-01-010-502 from the Senate Research Committee, University of Nebraska at Omaha.Received his Ph.D. in developmental psychology from the University of Wisconsin-Madison.

Birth order and self-concept in adolescence

The effect of birth order on self-concept was examined in a sample of adolescent boys and girls. Based upon self-theory, which suggests that the two main processes of self-concept formation (e.g., reflected appraisals and social comparisons) are affected by the power and role relationships associated with ordinal position in the family, several hypotheses were tested: (1) The self-evaluations of only and oldest children are more positive than those of younger siblings; (2) middle-borns have the lowest self-evaluations; (3) these relationships are affected by the sex and spacing of nearest sibling; and (4) the self-conceptions of oldest and only children are more similar to those of their parents than the self-conceptions of younger siblings and their parents. Using analysis of variance and several different measures of self-evaluation, very little support was found for any of these hypotheses. The strongest support was found for the hypothesis on middle-borns, but even these relationships were not large. Several explanations are offered for these weak and inconsistent findings.     

Health habits and depression in adolescence

In a study of the relationship between health habits and depression, 80 high school students, selected on an availability basis, were administered a Health Behaviors Questionnaire (HBQ) and the Beck Depression Inventory (BDI). The HBQ and the BDI significantly correlated (r=0.43p<0.01). Those who smoked were more frequently depressed than those who did not (X ²=10.5p<0.05), and those who used drugs other than marijuana were depressed more frequently than those who did not (X ²=9.2p<0.01). Mildly overweight boys (overweight by more than 5% of their ideal weight) and mildly under-weight boys (underweight by more than 5% of their ideal weight) were moreThis research was supported in part by a grant from the American Diabetes Association and by National institute of Health Grant MH 15529.Received his M.D. at George Washington School of Medicine.

The more pounds underweight the girls were, the more depressed they were (r=0.482, p<0.05). The closer the weight of a girl who perceived herself as overweight was to her ideal weight, the more depressed she was (r=–0.428,p<0.05).     

Manifestations of depressive affect in adolescence

This paper discusses the manifestations and correlates of depressive affect disorders in adolescents. It begins with some definitions and a discussion of the concept (from adult psychiatry) of depression and depressive disorders. The clinical picture of depressive disorders in adults is described, and the interrelationship is considered between them and the depressive disorders of adolescents and prepubertal children. Data are discussed regarding the external validity of adolescent depressive disorders (including their familial and biological correlates, their course and treatment outcome). Finally, the relevance of these data is summarized with regard to the process of establishing a diagnosis of a depressive disorder in adolescents.Received M.D. from Washington University.

Pregnancy in early and late adolescence

The degree to which adolescent pregnancy is viewed as a social problem varies with the age of the adolescent: the younger the adolescent, the greater the perceived risks and costs. The young adolescent has been found to be at greater risk medically; both the young adolescent and her infant are subject more frequently to prenatal and postpartum complications. A sample of 130 pregnant adolescents and adolescent mothers was surveyed to determine the factors that discriminate between girls who become pregnant in early years versus late adolescence. The younger group had begun dating and particularly steady dating at a significantly earlier age than the older group. The age discrepancy between the groups is even greater for the average age at which subjects began steady dating, that is, dating 1 boyfriend exclusively. While ages at which the adolescent began dating and particularly steady dating were found to be significantly related to early pregnancy, this vulnerability was increased by the subjects' lack of knowledge and use of birth control. Subjects in both groups reported that prior to pregnancy they desired quite frequently to leave their parents' home and be on their own. Early pregnancy appeared instead to have increased the adolescents' dependence upon her parents, especially the mother. The findings point to a need for instruction in reproduction and birth control to begin at an earlier age. Opportunity is needed for guided discussion among peers about their feelings regarding the costs and benefits of relationships and how one might deal with potential problems.     

Adjustment and sex-role orientation in adolescence

The purpose of the present study was to reexamine the relationship between sex-role orientation and self-esteem in adolescence. One hundred and six senior high school students completed the Rosenberg self-esteem measure (Rosenberg, 1965) and two measures of sex-role orientation, the Bem Sex Role Inventory, Short Form (BSRI; Bem, 1981), and the Personal Attributes Questionnaire Short Form (PAQ; Spence et al., 1975). The relationship between sex-role orientation and self-esteem was found to vary depending on the sex-role measure employed. Results of the BSRI revealed that androgynous individuals had higher levels of self-esteem than masculine, feminine, and undifferentiated adolescents. PAQ results indicated that androgynous individuals had higher levels of self-esteem than feminine and undifferentiated individuals. When the independent contributions of masculinity and femininity were assessed, both BSRI and PAQ masculinity and femininity significantly predicted self-esteem. Analyses also revealed that the effects of sex-role orientation on self-esteem varied by sex across both the BSRI and PAQ. Implications of the present findings for previous work on sex-role development in adolescence are discussed.Received Ph.D. in human development and family studies from Texas Tech University. Present research interests are sex-role orientation and its relationship to self-esteem, adjustment, and shyness in adolescents and young adults.     

Gender-role identity and psychological adjustment in adolescence

The relationship between gender-role identity (traditional, androgynous, cross-gender, and undifferentiated) and psychological adjustment among adolescents was examined. Hypotheses were derived from theories of gender-role identity development. One hundred and three high school students completed a measure of gender-role identity (the Bem Sex-Role Inventory) and four measures of adjustment (three Offer Self-Image scales and the Rosenberg Self-Esteem Scale). Findings indicate that traditional, androgynous, and cross-gender identities are each associated with some aspect of superior adjustment. Undifferentiated adolescents are poorly adjusted. When the independent contribution of masculinity, femininity, and gender-role identity to adjustment was assessed, masculinity and femininity had greater predictive power than gender-role identity. The relationship of findings to gender-role identity development is discussed.This paper was written while the author was a Postdoctoral Fellow in the Mental Health Research Program in Sociology and Psychiatry at Duke University Medical School.

The development of ego defenses in adolescence

This study tested a model for developmental transitions in defense use in adolescence based on an integration of psychoanalytic views of adolescence and Loevinger's theory of ego development. Loevinger's test for ego development and the Defense Mechanism Inventory were administered to 31 male and 35 female adolescents. Results supported several hypothesized developmental transitions: decrease in aggression outward defenses (e.g., displacement), increase in turning against the self, and an unpredicted increase in defenses entailing reversal (repression, denial, and reaction formation). Results failed to support a hypothesized increase in intellectualization and a decrease in projection. Results supported ego development over chronological age as a more valid index of maturity to apply to the investigation of the development of defenses. Implications of these findings are discussed and directions for future research are suggested.This research was partially funded by the Psychology Department at Boston UniversityAffiliations at the time when this study was conducted were Department of Psychology, Boston University, and Departments of Psychiatry at Beth Israel and McLean Hospitals/Harvard Medical School.

Ego development in adolescence: Longitudinal studies

Adolescents from four schools (one inner-city, two suburban, and one private) were tested two or three times using the Washington University Sentence Completion Test of Ego Development. Testing intervals ranged from 1.5 to 6 years. About half (N=193) the original pool was retested at twelfth grade. Every sample showed a mean rise in ego level; for six of eight samples that rise was statistically significant. Every pair of testings showed a postive correlation between scores; 10 of 14 correlations were significantly different from zero. Thus both test-retest correlations (about 0.5) and change scores support the hypothesized sequence of ego development. Significant correlation between ego level and intelligence occurred in two schools (0.6 at elementary and junior high grades and 0.4 at twelfth grade), but correlation was about zero in the private school.These studies were supported by Grant MH-05115 and Research Scientist Award MH-00657, both from the National Institute of Mental Health, Public Health Service.Received her Ph.D. from Washington University.

Cognitive mediators of ego functioning in adolescence

It has often been assumed that a relationship exists between higher levels of cognitive functioning, particularly formal operations, and mature ego functioning in adolescence. This research examined the relationships between ego functioning and two domains of operational thinking: social interpersonal reasoning and physical-mathematical reasoning in 139 high school seniors. Subjects were given two measures of physical-mathematical reasoning, two measures of interpersonal reasoning, and the Sentence Completion Test of ego functioning, as well as a measure of verbal intelligence. Results indicated significant differences between males and females in patterns of correlations as well as in patterns of relationships in a causal analysis. Ego functioning was predicted by interpersonal reasoning for females and by physical-mathematical reasoning and verbal intelligence for males.This research represents a portion of the doctoral dissertation completed by the senior author in 1981.

Gender-specific pathways to intimacy in early adolescence

As part of a larger longitudinal study of psychosocial development, 148 girls and 130 boys were administered a series of questions regarding a close friend during their eighth-grade school year. Scales corresponding to shared experience, self-disclosure, and intimacy (defined as emotional closeness) were developed from these items. Path-analytic models tested the relative strength of the self-disclosure and shared experience paths to emotional closeness for boys and girls separately. The results indicated that the self-disclosure path to emotional closeness is significant for both boys and girls. No relationship was found between shared experience and emotional closeness in girls when controlling for self-disclosure. The relationship between shared experience and feelings of closeness was, however, significant for boys even while controlling for the effects of self-disclosure. Covariance structure analysis (LISREL) indicated that the covariance matrices for the three scales were significantly different for boys and girls. The results are considered in relation to the gender socialization and friendship literature. The potential importance of defining intimacy as emotional closeness is also discussed.The research reported here was supported by National Institute of Mental Health Grant MH30252/38142 to Anne C.

Self-doubt in late childhood and early adolescence

This study examined the development of self-doubt in late childhood and early adolescence. Self-doubt was operationalized as the self-reported degree of uncertainty about the self's attributes. According to social-cognitive theory, self-doubt should decrease as social norms for self-evaluation are acquired through role-taking development. Seventy-five children at three ages-10, 13, and 16—were administered Selman's role-taking interview, a measure of social desirability, and a multidomain measure of self-doubt. Consistent with the social-cognitive model, self-doubt decreased with age during early adolescence. Role-taking ability increased with age. However, advances in role taking were not necessary for the resolution of self-doubt, nor could the decline in self-doubt be attributed to the tendency of older adolescents to conceal socially undesirable feelings. The findings support the view that adolescence is a period of consolidation for self-evaluations.Portions of this paper were presented at the meetings of the Society for Research on Child Development, Toronto, Canada, April 1985.Current interests include cognitive development and child psychotherapy, self-evaluation, and child psychopathology.     

The multidimensionality of peer pressure in adolescence

A sample of 689 adolescents (grades 7–12) from two Midwestern communities who had been identified by peers as members of one of three major peer groups responded to a self-report survey measuring perceptions of peer pressure in five areas of behavior: involvement with peers, school involvement, family involvement, conformity to peer norms, and misconduct. Perceived pressures toward peer involvement were particularly strong, whereas peer pressures concerning misconduct were relatively ambivalent. Perceived pressures toward misconduct increased across grade levels and pressures to conform to peer norms diminished; grade differences in perceived peer pressures concerning family involvement were community specific. Compared to druggie-toughs, jock-populars perceived stronger peer pressures toward school and family involvement, and less pressure toward (stronger pressure against) misconduct; patterns of perceived pressure among loners were more variable across communities. Results elaborated the process of peer influence in adolescent socialization and identity development.A version of this paper was presented at the biennial meetings of the Society for Research in Child Development, Toronto, April 1985.

Paired-associate learning and formal thinking in adolescence

The development of paired-associate (PA) learning and formal thinking during adolescence was investigated with 78 sixth and tenth grade students. Group-administered tests of formal and divergent thinking were given in the tracked, classroom setting. The augmented PA treatment provided, and the minimal PA treatment did not provide, verbal and pictorial prompts. The percentages of children showing formal thinking increased and converged to the 40% mark for both high and average achievers. While the augmented treatment scores were significantly better than the minimal treatment ones, the evidence was ambiguous concerning whether there was a developmental improvement in spontaneous elaboration skills for high achievers. The hypothesis predicting PA learning to be positively related to divergent thinking, and negatively related to formal thinking, was not supported.Received his Ph.D. in educational psychology from Mississippi State University.
