Influence of the developmental schedule of puberty on learning and ego functioning

Developmental schedules refer to temporal factors of pubertal processes as they might bear on ego development. The longitudinal research reviewed here from the 30-year archives of the Guidance Study of the Institute of Human Development pertains to the effects of varying lengths of the prepubertal and pubertal period on the short-term and enduring integration of drive states initiated at puberty. The personality correlates of varying lengths of these periods serve as vehicle for establishing properties of these stages as well as of the transition between them. The different ways the sexes respond to the early onset of puberty, as reported here, may provide an important microcosm for understanding normative sex differences in the general regulation of drive states.This research was supported by Grant MH 06238-02 from the U.S. Public Health Service, grants from the Ford Foundation, and a grant to the author from the Foundations' Fund for Research in Psychiatry.Presented at the Seventh Annual Adolescent Medicine Seminar, George Washington University Medical Center, March 15, 1971.Received Ph.D. in psychology from the University of California.

Aggression and delinquency: Family and environmental factors

Juvenile delinquency has become an increasing concern to society; aggressive behaviors are particularly harmful. This study examined parent and youth behaviors and personality types that may influence delinquent and aggressive behaviors. Youths were referred by the court to an intervention program; ratings of delinquency and aggression were derived from parent reports, self-reports, and court referral data. Results showed that high parent ratings of youth aggressiveness were related to high turmoil in the home and to youths' positive opinions of delinquent peers, while high aggressiveness of the youths' referring offenses was related to lax punishment. Developmentally, this suggests that in adolescence both the peer group and home influences are important in shaping different aspects of the youths' aggressive and delinquent behaviors.This study was partially conducted under University of Virginia Research Policy Council Grant No. 199505. The study was funded in part by a NICHD Training Grant (HD07289) to Dr. D. W. Fulker.

The state of research on ego identity: A review and appraisal

In the first part of this review (see Volume 7, Number 3 of this journal), a comprehensive survey of empirical research on ego identity was presented. Special emphasis was given to the large number of studies employing James Marcia's identity status paradigm. Research within this paradigm is recapitulated here by presenting empirical results which typify each of the four identity statuses (i.e., achievement, moratorium, foreclosure, and diffusion). A detailed evaluation of the identity status paradigm itself follows. Among the topics considered are (1) the construct and external validity of the approach as a whole, (2) the rationale and discriminant validity of the identity statuses, and (3) the reliability of the Identity Status Interview. Part II concludes by considering a number of problems for future research. Several persisting methodological and substantive issues within the identity status paradigm are noted. Finally, it is suggested that investigators turn their attention to the processes mediating identity formation. Contemporary psychoanalytic conceptions of adolescent development are viewed as providing one possible theoretical framework for investigating such processes.Support for this study comes from Research Training Grant No. 5T32MH14668-02 awarded to Dr. D.

Parental contexts of adolescent self-esteem: A developmental perspective

Relationships between parental behaviors and adolescent self-esteem were analyzed in a group of 95 early adolescents from multiple settings. The study was designed to investigate hypotheses regarding associations between observed parental interactions (e.g., accepting and devaluing) and adolescent self-esteem. Parents' verbal interactions with their adolescents were assessed through application of the constraining and enabling coding system to transcribed family discussions, generated through a revealed differences procedure. Adolescent self-esteem was measured with the Coopersmith Self-Esteem Inventory. Parent interaction-self-esteem associations were examined in the pooled sample, as well as in specific sub-groups based on gender, health, and ego development (measured by the Washington University Sentence Completion Test). Boys had more numerous associations between their self-esteem and parental interactions than girls, and psychiatrically ill boys had particularly high associations. Parental interactions were found to be most strongly related to adolescent self-esteem for adolescents at the lowest levels of ego development. Our findings are consistent with the view that increasing individuation in self-esteem regulation occurs during adolescent development, such that adolescents at higher levels of ego development evaluate themselves more independently of parental feedback than do their less mature peers.This study was supported through a Research Training Grant No. MH16259 (Dr. Isberg) from the NIMH, a grant from the National Institute of Child and Human Development (NICHD Grant No. 5 R01 HD18684-02), and a Research Scientis Development Award No. 5 K-02-MH-70178 (Dr. Hauser) from the NIMH.Received M.D. from Harvard University.

Clinical observations of ghetto four-year-olds: Organization,involvement, interpersonal responsiveness,and psychosexual content of play

This study attempted to refine the assessment of the effectance of four-year-old children through observation of their play. Two scales were developed; the first scale defined organization, involvement, and interpersonal responsiveness in play, and the second operationally defined psychosexual content of play. The validity and reliability of both scales and the inter correlations among the four major variables were explored. The results confirmed the validity and reliability of the instruments as measures of the children's effectance and important indicators of a child's capacity as a learner at age four.This research was carried out at the Dr. Martin Luther King Family Center and was supported by the Kenneth F.

Timing of menarche,preparation, and initial menstrual experience: Replication and further analyses in a prospective study

The goals of this study were to assess the significance of two timing variables (objective timing of menarche and subjective timing, i.e., the belief—not necessarily true—about one's status as early, average, or late maturing) and two cognitive variables (preparation for menstruation and ego functioning) as predictors of the experience of menarche. Subjects were 92 girls who changed from pre- to postmenarcheal between two test occasions, six months apart. Findings were that subjective timing of menarche and preparation were significant predictors of menarcheal experience, while objective timing and ego functioning were not. The results replicated earlier findings based on cross-sectional analyses. Interpretation of the results suggested some directions for further exploration of determinants of initial menstrual experience.This research was supported by National Institute of Child Health and Human Development Grant 16034 to the first two authors.Received Ph.D. from Clark University.

Sex differences within the family: Studies of adolescent and parent family interactions

Sex differences in verbal family interactions were investigated in a group of 79 adolescents and parents from normal and psychiatric settings. The analyses were designed to study these differences in both generations, parent and adolescent. Parent and adolescent interactions with one another were observed in a semistructured, revealed-differences family discussion. All of the individual speeches were then scored with our Constraining and Enabling Coding System (CECS). Initial predictions involved both adolescent and parent differences. These hypotheses were only partially confirmed. The strongest findings pertained to parent sex differences, as we found strikingly higher levels of cognitive enabling speeches expressed by fathers and significantly more speeches addressed to fathers. We discuss several alternative interpretations of these findings. Perspectives included in our considerations are direction of effect and influences of task/context upon the expression of family sex differences.This study was supported through a grant from the National Institute of Child and Human Development (NICHD Grant No. R01 HD18684-02) and a Research Scientist Development Award No. 5 K-02-MH-70178 (Dr. Hauser) from the NIMH.Received M.D. from Yale University and Ph.D. from Harvard University (psychology).

The state of research on ego identity: A review and appraisal

Considerable research on ego identity has appeared over the past 15 years, indicating the need for an overall review. Part I commences by considering the complexity of Erikson's concept and suggesting several different theoretical contexts in which it has been used. The validity of investigators' attempts to operationalize the concept ego identity is assumed to depend in part upon their interpretations of its meaning. The subsequent review of empirical literature is organized according to different procedures which have been used to measure ego identity. A first section summarizes and evaluates research utilizing Q-sort and self-report questionnaire measures, while a second considers the large number of investigations that have employed James Marcia's Identity Status Interview. The latter group of studies are ordered according to the type of dependent variable (e.g., cognitive, behavioral, personality, developmental) examined in relation to ego identity status (i.e., achievement, moratorium, foreclosure, diffusion). Part II of the review, to appear in the next issue of this journal, will recapitulate the identity status literature, present an overall evaluation of the identity status paradigm, and suggest a number of issues for future research.Support for this study comes from research training grant No. 5-T32MH14668-02 awarded to Dr. D.

Development of an objective measure to assess ego identity in adolescence: Validation and replication

Three studies that evaluate the reliability and validity of the Extended Version of the Objective Measure of Ego Identity Status (Adams and Grotevant, 1983) are reported. In Studies 1 and 2, college students in Texas and Utah, respectively, completed the identity measure, the Extended Range Vocabulary Test, and the Crowne-Marlowe Social Desirability Scale and released achievement results from their college records. The identity measure was found to have acceptable reliability (both internal consistency and test-retest) and validity (content, factorial, discriminant, and concurrent). In Study 3, scale scores from the objective identity measure correlated in the predicted pattern with ratings of identity exploration and commitment made from the Ego Identity Interview. Although the objective measure is not intended to replace the interview, it would appear to be useful in a number of situations where administration of the interview is impractical.We gratefully acknowledge the assistance of Dan Tousley in the data collection and data analysis phases of this research.

New views on cognitive development

Recent empirical findings viewed from a cognitive developmental perspective suggest new interpretive stances toward three familiar themes —the fears of infancy, the discontinuous quality of stages in cognitive functioning, and the capacity for resilience in cognitive development. (1) Time of onset and decline of separation anxiety in infants are primarily a function of the infant's level of cognitive development rather than variation in interactive experiences with the caretaker. (2) Cognitive competences seem to be severely limited to specific problem contexts, and we should not talk of competences in the abstract. Hence stages should be viewed as continuous and gradual. (3) Young mammals seem to retain a capacity for recovery from early experiences that retard normal development if they are fortunate enough to be moved to a more benign context.The research summarized in this article was supported over the past 18 years by grants from the National Institute of Child Health and Human Development, the National Institute of Mental Health, the National Science Foundation, the Carnegie Corporation of New York, the Spencer Foundation, the Office of Child Development, the Foundation for Child Development, and the Grant Foundation.Delivered at the Tenth Anniversary of Pritzker Children's Psychiatric Unit of Michael Reese Hospital and Medical Center, Dr. P.

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.

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.

The impact of the identity crisis on the adjustment of late adolescent males

The relationship between ego identity status and MMPI scores was investigated using 73 college males. Identity status was assessed using a semistructured interview. The results obtained indicated that subjects in the identity achievement status obtained MMPI scores which fell within the normal range of functioning. Subjects currently involved in working on identity issues (moratorium status) obtained a pattern of scores indicating the presence of psychological conflict, as did foreclosure subjects—that is, subjects who are characterized by rigid adherence to parental norms and values. Subjects who had not successfully resolved their identity crisis (identity diffusion status) had MMPI scores within the normal range. The findings partly support Erikson's theorizing on ego identity and indicate that further analysis and refinement of Marcia's typology is required. Results from the present study also indicate that future research with male subjects on ego identity status should include some assessment of sexual attitudes.This research was partly supported by research grants from the National Science Foundation (NSF-USDP No. GU 1598) and a grant from the National Institute of Mental Health (MH 16899).

Depressive symptomatology among very early maturing girls

This study investigated whether menarche is associated with depression when its onset is at the very early extreme of the normal age range. Girls who were postmenarcheal at the beginning of the sixth grade, comprising less than 10% of a sample of girls in that grade, were classified as very early maturers; their scores on the Beck Depression Inventory, short form (BDIs), were compared with those of their premenarcheal peers. Additionally, postmenarcheal seventh graders, who comprised 30% of a sample of girls in that grade, were compared to their premenarcheal peers on the BDIs. Results were that postmenarcheal sixth graders were significantly more depressed than their premenarcheal peers, but that postmenarcheal and premenarcheal seventh graders did not differ significantly. The results suggest that very early menarche is associated with higher levels of depression than more normative menarcheal timing.This research was supported by Grant 16034 from the National Institute of Child Health and Human Development.

Gender issues in the interface of family experience and adolescents' friendship and dating identity

This study focuses on the role of family experience in adolescents' conception of the self in the context of friendship and dating relationships. Three issues are addressed: the extent of sex differences in adolescents' friendship and dating identity, how links between family experience and friendship and dating identity might differ for males and females, and whether mothers and fathers play distinctive roles in such development. A sample of Caucasian two-parent families, each including an adolescent who was a high school senior, was observed in a family interaction task designed to elicit the expression and coordination of a variety of points of view. Each adolescent was also given an interview assessing exploration and commitment in friendship and dating identity. Only one sex difference was found in identity, with females more committed in their conceptions of dating relationships than males. The key finding of the study concerns the distinctive patterns of family interaction associated with friendship and dating identity. For females, separateness in family interaction was related to their friendship identity exploration, whereas for males, the links between family interaction and exploration all involved connectedness. The different contingencies may reflect the interplay between different societal patterns of support and restriction of males' and females' exploration.This work was supported by grants from the National Institute of Child Health and Human Development (HD-92819 and HD-17983) and the Hogg Foundation for Mental Health and from the University Research Institute and the Institute of Human Development and Family Studies of the University of Texas at Austin.Received her Ph.D. in child psychology from the University of Minnesota.

Contraceptive embarrassment and contraceptive behavior among young single women

The objective of this paper was to determine factors predictive of contraceptive embarrassment and to determine the relationship of contraceptive embarrassment to contraceptive use among young unmarried females. Contraceptive embarrassment was measured by an eight-item scale (a=0.88]. Data were obtained from 265 nonvirgin high school and university females who were currently dating. Using simple multiple regression, 30% of the variance of the embarrassment scale was explained, with the most important predictors being parental attitude to premarital intercourse and sexual guilt. Other significant predictors were attitude to planning ahead to use contraception, perveived difficulty in obtaining contraceptive devices, and peer attitudes toward premarital intercourse. The embarrassment scale had significant correlations with contraceptive use.Sponsorship from Health and Welfare Canada through Family Planning Grant No. 4470-5-10 provided for the data collection, and sponsorship from the National Institute of Child Health and Human Development, DH&W, Contract No. N01-HD-92809 provided for the data analysis.Received his Ph.D. from Department of Sociology, Iowa State University and is interested in the sociology of adolescence, particularly dating, sexual relations, and use of contraception.     

Approach and avoidant coping: Implications for adolescent mental health

We conducted a short-term longitudinal study examining the structure of coping behavior and the relationship between coping style and depression during adolescence. The sample consisted of 603 adolescents in Grades 6–11 who were surveyed in the fall of 1989 and again in the fall of 1990. A two-dimensional model of coping was found using confirmatory factor analysis with the factors being approach and avoidant coping. Four cross-sectional and seven longitudinal coping groups were formed to explore group differences in depression. Approach copers reported the fewest symptoms of depression, while avoidant copers reported the most. Subjects who changed over time from approach to avoidant coping evidenced a significant increase in depressive symptoms, whereas subjects who switched from avoidant to approach coping displayed a significant decrease in depression over a one-year period. These findings imply that adolescents who are able to elicit social support, engage in problem solving, and cognitively restructure events within a positive light are more likely to successfully negotiate the challenges of adolescence.This research was supported by a grant from the William T.

Adolescent personality antecedents of completed family size: A longitudinal study

Comprehensive personality assessments, made independently for early and late adolescence, were employed to predict the subsequent family sizes of 52 women and 54 men with single continuous marriages throughout their parenting careers. (These participants have been studied longitudinally over a 40-year span in either the Oakland Growth Study or the Berkeley Guidance Study.) Final family size relates negligibly to earlier personality for men, but is substantially predictable highly significantpositive correlations demonstrated withintellectual competence of girls at both adolescent age levels and independently within the two cohorts studied. Alternative hypotheses to account for this unexpected result are presented, and further research is proposed to determine whether the relationship is cohort-specific (to women born in the 1920s) or, instead, likely to hold for current and future generations of women.This research was supported by Grant HD 09191-01 from the U.S. Public Health Service.The data employed are drawn from the longitudinal archives of the Oakland Growth Study and the Berkeley Guidance Study, both at the Institute of Human Development, University of California, Berkeley.Main research interest is the longitudinal study of personality development.     

Self-image complexity and identity formation in adolescence: Longitudinal studies

Using a specially designed Q-sort technique, multiple self-images which were held by each of 60 adolescents were studied. Sixty normal and psychiatrically hospitalized adolescents were tested initially and then every 6 months for 12–18 months. Each subject's self-images were analyzed in terms of their complexity. Results showed that, as predicted, the patients and normals differed significantly. The patients had consistently lower complexity scores on each trial. The patients' and normals' patterns of complexity scores are discussed in terms of their reflecting the ego identity configurations described clinically by Erikson and operationally defined herein.This study was supported in part by a Research Scientist Development Award (Kl-70-178) from the National Institute of Mental Health.Received his medical training at Yale University School of Medicine and his psychiatric training at Massachusetts Mental Health Center.
