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.

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).

A self-report measure of pubertal status: Reliability,validity, and initial norms

Puberty is a central process in the complex set of changes that constitutes the transition from childhood to adolescence. Research on the role of pubertal change in this transition has been impeded by the difficulty of assessing puberty in ways acceptable to young adolescents and others involved. Addressing this problem, this paper describes and presents norms for a selfreport measure of pubertal status. The measure was used twice annually over a period of three years in a longitudinal study of 335 young adolescent boys and girls. Data on a longitudinal subsample of 253 subjects are reported. The scale shows good reliability, as indicated by coefficient alpha. In addition, several sources of data suggest that these reports are valid. The availability of such a measure is important for studies, such as those based in schools, in which more direct measures of puberty may not be possible.This research was supported by a grant to A.C.P. from the National Institutes of Mental Health (MH 38052/38142).She earned the Ph.D. in Measurement, Evaluation, and Statistical Analysis at the University of Chicago.

Gender differences in identity formation as a function of self-other relationships

Effects of differential male-female relational definitions of self on resolutions to the first six of Erikson's identity crises were examined in a sample of 388 adolescent males and females. Subject categorization of relational self-definitions was based on the Relational Self-Definition Scale. Resolutions to identity crises were measured by the Erikson Psychosocial Stage Inventory (EPSI). Predictions were drawn from theoretical notions related to Gilligan's view of distinctive male-female trends in self-other development and indicated that males with self-definitions separate from others and females with self-definitions connected with others would report higher degrees of positive resolutions on EPSI subscales compared to males with connected self-definitions and females with separate self-definitions. Results revealed that specific predictions were supported for resolutions to Trust, Initiative, and Intimacy crises independent of individual differences in age, educational level, vocabulary, and socioeconomic status of subjects. This suggests that gender differences in identity development may be linked to distinctive malefemale trends in the use of relational self-definitions consistent with Gilligan's views.Received Ph.D. from Wayne State University in applied/personality psychology.

Sex role and dating orientation

The assumption that males approach dating from a pronounced psychobiological orientation while females approach it from a psychoaffectional orientation was questioned. The sex role adopted by the individual was considered to be as important a variable as biological sex. Male and female subjects from three age groups, 16–17 years, 19–20 years, and 24–25 years, completed questionnaires designed to measure their sex roles and dating orientations. All groups of males were found to approach the dating relationship from both a psychoaffectional and psychobiological orientation, while all groups of females approached it from a psychoaffectional orientation and showed an increase in psychobiological orientation with increasing age and increasing depth of relationship. Significant differences were also found in dating attitudes between male and female subjects adopting different sex roles. It was concluded that neither masculinity and femininity, nor psychobiological and psychoaffectional attitudes to dating, lie on single continua. Masculine and feminine sex roles as independent dimensions influence psychobiological and psychoaffectional orientations to dating which are in themselves independent dimensions and not ends of a single continuum.Received her B.A. (Hons. 1) at Macquarie University and Dip.

Race and Perceived Pubertal Transition Effects on Girls’ Depressive Symptoms and Delinquent Behaviors

Most past research on the effects of early pubertal timing on girls’ depressive symptoms and delinquent behavior has focused on either age of menarche or has combined multiple indicators of development into a single index of puberty. Past research has rarely examined both the onset of puberty such as age of menarche, as well more psychologically mediated impressions of puberty (i.e., perceived pubertal timing) within the same study. This study extends past research on racial differences and pubertal related effects on girls’ depressive symptoms and delinquent behavior by examining the independent influence of different indicators of puberty (age of menarche, development of breasts, and perceived pubertal timing). Two waves of data (100 % females) were used from African Americans (N = 481) and European Americans (N = 1259) who were enrolled in seventh- and eighth-grade during the first wave of data collection in the National Longitudinal Study of Adolescent Health. Early age of menarche was associated with high levels of depressive symptoms at Wave 1. Additionally, both early and late perceived pubertal timing were associated with high levels of depressive symptoms and high delinquent behaviors at Wave 1. The structural relationships among these variables were similar for African Americans and European Americans. Age of menarche and perceived pubertal timing influenced depressive symptoms and delinquent behavior at Wave 2 through depressive symptoms and delinquent behavior reported at Wave 1. The implications of these findings are discussed with an emphasis on how the specific indicator used to assess puberty is important in efforts to understand pubertal timing effects.     

Sex differences in identity and intimacy development in college youth

This study examined sex differences in the processes of identity and intimacy development among college youth. Fifty males, and 50 females were given measures of identity status, intimacy status, and self-esteem. Males were found to focus on intrapersonal aspects of identity status, intimacy status, and self-esteem. Males were found to focus on intrapersonal aspects of identity, females on interpersonal aspects. The pursuit of various identity development pathways affected self-esteem differentially for the two sexes. More females than males were found to be intimate and the achievement of intimacy seemed more closely related to identity in males than in females. The findins were interpreted in the context of Eriksonian theory, which seemed more adequate in explaining male than female development.This article is based in part on the doctoral dissertation by James W.

Pubertal Development Moderates the Importance of Environmental Influences on Depressive Symptoms in Adolescent Girls and Boys

Prevalence differences in depressive symptoms between the sexes typically emerge in adolescence, with symptoms more prevalent among girls. Some evidence suggests that variation in onset and progression of puberty might contribute to these differences. This study used a genetically informative, longitudinal (assessed at ages 12, 14, and 17) sample of Finnish adolescent twins (N = 1214, 51.6% female) to test whether etiological influences on depressive symptoms differ as a function of pubertal status. These tests were conducted separately by sex, and explored longitudinal relationships. Results indicated that pubertal development moderates environmental influences on depressive symptoms. These factors are more important on age 14 depressive symptoms among more developed girls relative to their less developed peers, but decrease in influence on age 17 depressive symptoms. The same effects are observed in boys, but are delayed, paralleling the delay in pubertal development in boys compared to girls. Thus, the importance of environmental influences on depressive symptoms during adolescence changes as a function of pubertal development, and the timing of this effect differs across the sexes.     

Identity formation,nAchievement, and fear of success in college men and women

This study examined the performance of male and female identity statuses on achievement-related variables to clarify whether the four identity positions have different consequences for men and women. Previous research had suggested that an identity crisis period (achievement and moratorium) was more adaptive for males, while identity commitment, with or without a crisis period (achievement and foreclosure), was more adaptive for females. Identity status was determined for 111 college men and women who were tested for nAchievement, fear of success, fear of failure, and self-esteem. As predicted, identity achievement and moratorium men and women scored higher in achievement motivation and self-esteem than foreclosure and diffusion subjects. However, while diffusions and foreclosures were highest in fear of success of the male statuses, moratoriums and achievements were highest in fear of success of the female statuses. Contrary to previous research, the results indicate that moratorium women resemble identity achievements more than foreclosure women do, at least on achievement-related and self-concept variables, and suggest reasons why moratorium has appeared in past research to be a less adaptive status and foreclosure a more adaptive status for women.This research was supported by University of Missouri Summer Research Fellowship 3694-1100.Received his Ph.D. in clinical psychology at the State University of New York at Buffalo in 1974.

The Family Antecedents and the Subsequent Outcomes of Early Puberty

The purpose of this study was to examine both the family antecedents and the outcomes of early puberty, with a particular focus on factors related to family socioeconomic status (SES). The study employed a comprehensive measurement of pubertal development and longitudinal data from the Canadian National Longitudinal Survey of Children and Youth. The sample (N = 8,440; 49% girls) included four cohorts of children who were followed biennially for 10 years, starting from age 4–11 to 14–21 years. Data were drawn at different years of age from these cohorts of children. Girls whose fathers were unemployed were more likely to experience early puberty than those whose fathers were employed. For boys, those living with fathers who had not finished secondary school were more likely to experience early puberty. Early maturing girls tended to engage in smoking and drinking at an earlier age compared with their peers. These findings provide support for psychosocial acceleration theory and suggest that different aspects of low family SES may act as a psychosocial stress for early pubertal maturation in boys versus girls, which may lead to engagement in drinking and smoking at a younger age, at least for girls.     

Adolescent Depressed Mood in a Multiethnic Sample

This research assessed whether there is an impact of race-ethnicity on depressed mood among adolescents, independent of socioeconomic status, whether gender differences in depressed mood are apparent within all race-ethnicity subgroups, and whether pubertal development influences depressed mood in a similar manner within gender and race-ethnicity subgroups. A three-stage, area probability sampling frame was utilized to select adolescents, ages 12–17 years, for an in-person interview. Depressed mood was assessed by the Children's Depression Inventory. Compared to Whites, African Americans, or Asian Americans, Latinos reported more symptoms of depressed mood, a finding that was independent of socioeconomic status. Advancing puberty was associated with depressed mood only among females, but the timing of pubertal changes, relative to ones peers, was related to depressed mood among both males and females, and among Latinos.     

Moral judgment and sex role orientation as a function of self and other presentation mode

Gilligan's concern for a negative bias in assessing moral reasoning based on feminine interpersonal orientations and corresponding positive bias in favor of masculine orientations of justice and equity was explored. Bem's Sex Role Inventory provided a psychological index of orientation rather than only biological sex. College men and women completed Rest's moral dilemmas (DIT) in the usual manner-other condition-or assumed the role of the central character-self condition. The latter procedure augmented affective dimensions assumed to underlie orientation differences. Males in the other condition scored higher on the DIT than those in the self condition; females revealed the opposite pattern. Using the sex role categories, it appeared that androgynous males had higher DIT scores in the self condition than in the other condition, in direct contrast to the overall results for males. For females who were androgynous or masculine in orientation, the self condition resulted in higher DIT scores than the other condition. Generally, the greater affective demands in the self condition produced a higher frequency of Stage 3 use for men and women regardless of sex role orientation. The other condition showed a higher percentage of Stage 4 use among males and females independent of sex role orientation. Sex role orientation and affective arousal were discussed in terms of Gilligan's view of moral judgment development.Portions of this paper were presented at the biennial meetings of the Society for Research in Child Development, Baltimore, MA, April 1987.Received Ph.D. from the University of Wisconsin, Madison Current research interests are logical concept development and moral and political development.Received Ph.D. from Purdue University.

The adolescent self-concept: A functional determinant of consultant preference

The consultant preferences of adolescents were examined in relation to self-worth and locus of control. A total of 247 subjects, 122 males and 125 females, ranging in age from 13 to 18 years, completed questionnaires indicating self-worth and locus of control orientation. These subjects also rated their preference for four generic consultant categories (a familiar adult, an adult expert, a familiar peer, or peer expert) in three hypothetical problem situations—an impersonal problem, an interpersonal problem with a peer, and an interpersonal problem with a parent. Analyses were conducted on the dependent measure of preference scores. A six-way analysis of variance was conducted with the independent variables of age, sex, self-worth, locus of control, and the repeated measures of situation (across three levels) and consultant choice (across four levels). The results reveal a significant three-way interaction between age, sex, and consultant choice. The results also indicate a significant four-way interaction between self-worth, locus of control, situation, and consultant choice. This interaction between personality variables, problem domain, and consultant characteristics contains practical implications for prevention and intervention.Has a Ph.D. in developmental psychology.

Suicidal ideation in adolescence: Depression,substance use,and other risk factors

The interrelationships of depression and suicide with adolescent drug use, delinquency, eating disorders, and the risk factors for these different problems were investigated among 597 9th and 11th graders in an urban high school. There is a strong association of drug use with suicidal ideation among girls, and a stronger relationship with attempts among girls and boys. Suicidal youths are ill-adjusted and display a lack of attachment and commitment to family and school. Causal models indicate that poor interpersonal interactions with parents, absence of peer interactions, and life events lead to depression, which in turn leads to suicidal ideation. Depressive symptoms are the strongest predictors of suicidal ideation. Among females, depression predicts drug involvement, and in turn, drug use increases suicidal ideation. Drug use is only one class of problem behaviors that constitutes a risk factor for suicidal behavior in adolescence. Delinquency and eating disorders also have direct effects on suicidal ideation beyond those of depressive affect. As for drug involvement, these problem behaviors are more predictive of suicidal behavior among girls than boys. Similarity and specificity of the predictors for problem behaviors within and between the sexes are discussed. Although young women use drugs to handle feelings of depression, drug use appears ineffective in the long run in relieving these depressive feelings. Understanding the dynamics of suicidal ideation in adolescence has important public health implications, since ideation is a strong predictor of attempts, especially among females.Revised version of a presentation at the Workshop on Adolescent Depression, Princeton, NJ, June 3, 1987.Work on this research has been partially supported by Research Grants DA00064, DA01097, DA03196, and DA02867, and by Research Scientist Award DA00081 from the National Institute on Drug Abuse; and awards from the John D. and Catherine MacArthur Foundation and the Research Foundation for Mental Hygiene, New York State Psychiatric Institute.

Ego development and moral development in relation to age and grade level during adolescence

The relation between Loevinger's measure of ego development and moral development as indexed by Rest's Defining Issues Test was examined in a sample of 517 adolescents between 12 and 21 years of age. Major increases in moral capacity were found at the Conformist and Conscientious levels of ego development. Low positive correlations between ego level and moral capacity were reported for young adolescents but not for older ones. The development indices of age and grade were compared. Both ego and moral development seemed more closely related to grade level than to age. Socioeconomic status predicted acceleration in ego development at the rate of one half an ego level over middle to late adolescence. This effect persisted at university. Students of higher socioeconomic background attained developmental levels one to two years before their contemporaries of low socioeconomic status. Sex differences in ego development were in favor of females.This study was part of the author's Ph.D. thesis at the University of Manitoba, Winnipeg, Canada.

Dating,Parent–Adolescent Conflict,and Behavioral Autonomy

Although dating is thought to contribute to adolescent development, little is known about how it affects autonomy development and relationships with parents. The contributions of dating status, grade, gender, and family structure to the frequency and intensity of normative conflict and to behavioral autonomy were studied. Tenth- and twelfth-grade public high school students (N = 859) completed measures of dating history, frequency, and intensity of parent–adolescent conflict, and of behavioral autonomy. Current daters (n = 325) had more frequent conflict and reported higher levels of behavioral autonomy than nondaters (n = 170). Additionally, males and twelfth graders reported more autonomy than females and tenth graders, respectively. Sophomores who were dating reported the most frequent conflict with parents, females who were dating reported the most intense conflict with parents, and seniors who were dating reported the highest levels of autonomy. Short-term daters had more frequent and more intense conflicts with parents relative to long-term daters and nondaters. These data highlight the utility of focusing on developmental tasks in addition to age when assessing conflict patterns and processes.     

Adolescents' perceptions of their attachment relationships with their mothers,fathers, and friends

This study explored changes in New Zealand adolescents' perceptions of their attachment relationships with their mothers, fathers, and friends. The main findings revealed that from early to late adolescence: Males and females remained stable in their quality of affect toward their mothers. With increasing age, females utilized their mothers for support and proximity more, whereas males utilized their mothers for support and proximity less. With increasing age, males and females rated their quality of affect toward their fathers as lower and utilized their fathers for support and proximity less. Females had a higher quality of affect toward friends than males regardless of age, but both males and females increased their utilization of friends for support and proximity over age. Further analyses revealed that Pacific Island adolescents utilized their mothers less for support and proximity than European/Pakeha adolescents. Adolescents from one-parent families utilized their fathers less for support and proximity and had a lower quality of affect toward him than adolescents from two-parent families. These findings suggested that substantial changes take place in attachment relationships from early to late adolescence and highlighted the need for research to differentiate between the sex of adolescent and sex of parent dyads in order to examine adolescents' affective relationships effectively.This research is based on the first author's doctoral dissertation at the University of Auckland.Received Ph.D. from the University of Auckland.

Divergent thinking and self-esteem in preadolescents and adolescents

The purpose of this study was to explore the relationship between divergent thinking and self-esteem in preadolescents and adolescents. A second focus pertained to sex differences in the dependent variables. A total of 115 White middle class subjects ranging in age from 10–17 years responded to a personal data inventory, a self-esteem measure, and a taped auditory free-response exercise in divergent thinking. Subjects were categorized for data analysis into two age groups, preadolescents and adolescents. Scores were obtained for fluency, flexibility, and originality of thought, and for self-esteem. Adolescents were significantly more fluent and flexible than preadolescents. The two age groups did not differ significantly in orginality or self-esteem. Self-esteem correlated significantly with divergent thinking in preadolescents only. Female adolescents scored significantly higher on all dependent measures than adolescent males; there were no sex differences in preadolescents. Results are discussed from both an intra- and interstage developmental perspective on adolescence.Research assistant and doctoral canditate in human developmental and family studies at Cornell University.

Youthful smoking and drinking in a longitudinal perspective

The incidence and continuity of smoking and drinking, precursory social-behavioral characteristics of smokers and drinkers, and life conditions related to smoking and drinking are described. The study was part of an extensive Finnish longitudinal study of social development, the original sample of which consisted of 8-year-old subjects (196 boys, 173 girls) studied in 1968 by employing peer nomination and teacher ratings. The follow-up studies were made at ages 14 and 20. 154 Ss at age 14 and 135 Ss at age 20 were interviewed about their smoking and drinking habits, among others. The results showed that about 20% of the subjects smoked at age 14 and about 30% at age 20. The proportion of abstainers was about 25% at age 14 and 10% at age 20. The differences between the sexes were negligible. Smoking at age 20 was predictable on the basis of early initiation, but drinking was not. Aggressiveness at age 8, and orientation towards peers and negativism at age 14 predicted male and female smoking and male drinking and alcohol offences at age 20. Social characteristics did not predict female drinking. At age 20, male and female smoking and heavy drinking belonged to the way of life of Reveller, and smoking also to that of Loser. Smoking and drinking were related to parental models at age 20, but in puberty the influence of peers' smoking and drinking was stronger than that of the parental models. Lack of parental encouragement and affectional interaction with the parents was related to female smoking and male drinking. Youthful smoking and drinking were not connected with family socioeconomic status.
