Negative affect and hormone levels in young adolescents: Concurrent and predictive perspectives

The purpose of this study was to test hypotheses regarding (1) relations among negative affect and hormones of gonadal and adrenal origin in young adolescents, at three times of measurement, over a one-year period; and (2) stability of negative affect. The sample consisted of 10- to 14-year-old boys (N=56) and 9- to 14-year-old girls (N=52). The adolescents were assessed three times at 6-month intervals over one year. Serum levels of gonadotropins, gonadal steroids, adrenal androgens, and cortisol were assessed, as well as stage of pubertal development (Tanner criteria). The negative affect assessments consisted of self-report questionnaire and interview measures of anxiety and depressive affect, as well as mother reports of internalizing behavior problems. In the concurrent (cross-sectional) analyses, boys reporting higher levels of negative affect tended to be those at higher genital stage or older age, with lower testosterone and cortisol levels and lower dehydroepian-drosterone sulphate levels. In the longitudinal analyses, negative affect, and to a lesser extent hormone levels at the first time of measurement predicted negative affect 12 months later. The findings suggest that puberty-related hormone levels should be considered along with psychological characteristics in examining the processes involved in the development of negative affect during the pubertal years.Received Ph.D. from The Pennsylvania State University.

Pubertal Effects on Adjustment in Girls: Moving from Demonstrating Effects to Identifying Pathways

The present investigation examines mediated pathways from pubertal development to changes in depressive affect and aggression. Participants were 100 white girls who were between the ages of 10 and 14 (M=12.13, SD=.80); girls were from well-educated, middle- to upper-middle class families, and attended private schools in a major northeastern urban area. Three aspects of pubertal development were examined: (a) estradiol categories tapping gonadal maturation; (b) dehydroepiandrosterone sulfate (DHEAS) levels indicating adrenal maturation; and (c) pubertal timing (early vs. other). Three potential mediators were also examined: emotional arousal, attention difficulties, and negative life events. Tests of mediated models indicated that early pubertal timing predicted higher emotional arousal which subsequently predicted increased depressive affect. Negative life events, and possibly attention difficulties, mediated the associations of both estradiol category and DHEAS with aggression. These findings highlight the potential for more intensive investigation of gonadal and adrenal processes in explaining affective changes at puberty.

The Associations Among Perceived Pubertal Timing, Parental Relations and Self-Perception in Turkish Adolescents

This study is primarily aimed at investigating how pubertal timing is perceived in urban Turkish adolescents in terms of their feelings about maturation, their relationships with their parents, and their self-perception. A total of 697 high-school students (360 girls, 337 boys) between the ages of 14 and 18 (M=16.15, SD=1.08) were included in this study. The findings indicated that most of the adolescents perceived themselves as on-time developers in comparison with their peers. Consistent with widely available research data in the literature regarding the impact of early versus late maturation, girls who mature early and boys who mature late reported more negative feelings about pubertal maturation. In addition, those who matured early reported greater conflict and disagreement with their parents and more negative communication with their fathers than the adolescents who matured on- time. Adolescents who were less satisfied with their physical appearance were more likely to have negative feelings about pubertal maturation. Sex was found to act as a moderator of relationships between global self-worth and feelings about pubertal maturation. In conclusion, this study, conducted with Turkish urban adolescents, suggests that the impact of early versus late maturation differs between girls and boys, which is consistent with widely available data in the literature.     

Pubertal Maturation and Changes in Self-Image in Early Adolescent Finnish Boys

Onset of puberty is known to be a stressful period of life. The young adolescent must face several simultaneous developmental challenges, which are reflected as a gap in self-image. In this study, relationships between biological pubertal events and self-image were analyzed in a sample of 59 healthy adolescent boys from the Helsinki area. Detailed information on pubertal development was collected by a pediatrician at three-month intervals. The subjects filled in the Offer Self-Image Questionnaire at 13 and at 14 years and were interviewed by a child psychiatrist. During the year, self-image increased in four domains: Impulse Control, Emotional Tone, Sexual Attitudes, and Psychopathology. The changes in the first two domains were related to pubertal events. In contrast, changes in emotional health and in sexual attitudes did not correlate with bodily changes or testosterone. As regards body image, differences were not found in relation to age, but in relation to genital stages. These findings indicate that some aspects of self-image develop as a function of psychological and cognitive maturation, while other aspects are related to biological events.     

Pubertal Timing and Substance Use in Middle Adolescence: A 2-Year Follow-up Study

Earlier research has associated early puberty with emotional and behavioral symptoms particularly among girls, while among boys, findings have been contradictory as to whether risks are associated with early or late pubertal timing. We studied the association between pubertal timing and substance use behaviors in middle adolescence in a 2-year follow up study of 2,070 (mean age 15.5 years, SD 0.36; 56.4% females) Finnish adolescents. Pubertal timing was measured by age at menarche/oigarche. Eleven years or less was classified as early, 12–13 years as normative and 14 years or later as late pubertal timing. Substance use behaviors were elicited by a number of questions related to alcohol use patterns, smoking and cannabis use. As factors that could explain the association between pubertal timing and substance use, we studied depressive symptoms, delinquency and aggression, and parental monitoring. In boys, all these substance use behaviors were the more common the earlier the puberty and the associations persisted at age 17. Among girls, early pubertal timing was similarly associated with substance use behaviors at age 15, but no longer at age 17. The associations between pubertal timing and substance use behaviors persisted when symptom dimensions and parental monitoring were added into the models. Early puberty is a risk factor for substance use particularly among boys. Among girls, the impact of pubertal timing already tempers off during adolescence.     

Pubertal Timing and Adolescent Adjustment and Behavior: Conclusions Vary by Rater

The effects of pubertal timing on adolescent development have been studied since the late 1930s, yet the research has yielded inconsistent findings. One reason for such inconsistency may be the source of the rating. The purpose of this report was to examine whether pubertal timing by self-report (SR), parent report (PR), or physical exam (PE) predicted the same aspects of adjustment and behavior problems. Fifty-two girls, age 9–14 years (M = 12.0 ± 1.6) and 56 boys, age 10–15 years (M = 12.7 ± 1.3) and their parents were enrolled in the longitudinal study. Parents completed the Child Behavior Checklist and adolescents completed the Offer Self-Image Questionnaire. Using regression, later maturing boys and girls had more adjustment and behavior problems than on-time or earlier maturers in cross-sectional analyses. Longitudinally, there were few significant relationships between pubertal timing at the first occasion of measurement and adjustment and behavior problems 1 year later. Overlap in correlates of adjustment and behavior problems across raters was not always found. More significant findings were evident between pubertal timing and adjustment and behavior problems for boys than for girls and more for ratings by PE than by SR or PR. Caution appears in order when drawing conclusions about pubertal timing and adolescent behavior when rater of pubertal development or timing of rating varies across studies. The selection of who rates pubertal development and the timing of the ratings should be based on the underlying theoretical framework guiding the hypotheses.     

Pubertal timing and grade effects on adjustment

Effects on adjustment of biological maturation and social timing were compared using data from a longitudinal sample of 335 young adolescents, who were followed from the sixth through eighth grades. Biological maturation was estimated from the relative timing of the adolescent growth spurt. Social timing was assessed by grade in school. Five adjustment constructs were examined: school achievement (course grades in five subjects), family relations (a 17-item scale), peer relations (a 10-item scale), body image (an 11-item scale), impulse control (an 8-item scale), and psychopathology (an 11-item emotional tone scale and an 11-item general psychopathology scale). All but one adjustment construct showed grade effects, but only three of the six constructs showed pubertal timing effects. There were no grade by pubertal timing effects. Although there were gender differences for some of the adjustment constructs, there were no gender by pubertal timing effects. The results are discussed in terms of the life-span developmental perspective.Received Ph.D. from the University of Chicago in 1973.

Gender Differential Influences of Early Adolescent Risk Factors for the Development of Depressive Affect

Based on a model by Cyranowski, J., et al. (2000), Arch. Gen. Psychiatry 57: 21–27, adolescents at-risk for the development of depressive symptoms were identified. Adolescents were considered at-risk if they had 2 or more of the following early adolescent risk factors: (1) insecure parental attachment, (2) anxious/inhibited temperament, (3) low instrumental coping skills, and (4) early pubertal maturation. Nonrisk adolescents had zero or just one risk factor. Using data from a 10-year longitudinal study on the development of adolescents’ health, with 5 points of data assessment (i.e., 6th, 7th, 8th, 12th, and 12 + 4 follow-up), the impact of the four early adolescent risk factors on the development of emotional tone was investigated. Emotional tone was measured by the Emotional Tone Scale of the SIQYA (Petersen, A. C., et al. (1984), J. Youth Adolesc. 13: 93–111), an indicator for positive emotional tone and low depressed affect. Growth curve modeling was applied to reveal significant gender differences in level and slope for the development of emotional tone over the adolescent years. Latent Growth Curve Models can be seen as a combination consisting of repeated measures analysis of variance and autoregressive analyses to evaluate the latent change of the variables under investigation (Rovine, M. J., and Molenaar, P. C. M. (2000), Multivar. Behav. Res. 35(1): 51–88). At-risk girls revealed poorer levels of emotional tone which stayed almost at the same low level up to young adulthood (i.e., 12 + 4), indicating a long lasting impact of the specified risk factors. In contrast, at-risk boys showed poorer emotional tone in early adolescence, but at the end of adolescence boys at-risk had the same level of emotional tone as nonrisk boys. At-risk girls showed significantly higher levels of depressive symptoms at grade 12 and at 12 + 4.Assistant Professor at the Department of Psychology, University of Erlangen-Nuremberg.

The Role of Peer Stress and Pubertal Timing on Symptoms of Psychopathology During Early Adolescence

Stress is known to amplify the link between pubertal timing and psychopathology. However, few studies have examined the role of peer stress as a context for this link. The present study examined the interaction between perceived pubertal timing and peer stress on symptoms of psychopathology in early adolescence. The sample consisted of 264 students (63% female; M _age = 12.40, SD = 1.00; 55% Caucasian, 23% African American, 7% Latino, 11% biracial and 4% other). Higher peer stress was associated with symptoms of anxiety/depression; this effect did not vary by timing or gender. However, early-maturing girls with high peer stress demonstrated higher rates of relational and overt aggression compared to other girls. Findings also suggested that late-maturing boys with high stress are at risk for aggression problems; however, due to the small number of boys, analyses were exploratory. Overall, results suggest that developmentally salient contexts as indicated by stressful peer experiences may pose unique threats to early maturing girls and possibly late-maturing boys.     

Genetic and Environmental Influences on the Association Between Pubertal Maturation and Internalizing Symptoms

The literature consistently shows an association between pubertal maturation and internalizing problems in girls. The association for boys is less clear. The present study examines genetic and environmental influences on the association between pubertal maturation and internalizing problems for boys and girls in two primarily Caucasian adolescent twin/sibling studies: The Swedish Twin study of CHild and Adolescent Development (706 same-sex twin pairs aged 13-14, M = 13.7 years, 50 % female), and the Nonshared Environment in Adolescent Development sample (US-based, 687 same-sex twin/sibling pairs aged 10-18, M = 13.6 years, 47 % female). For girls, more advanced pubertal maturation was associated modestly with more internalizing problems, and that association was entirely explained by shared environmental influences. For boys, the association between pubertal maturation and internalizing problems was weak and inconsistent. Results for girls were remarkably consistent across samples. Findings suggest that nongenetic mechanisms mediate the association between pubertal maturation and internalizing problems. Findings have implications for intervention such that environmental influences shared by twins/siblings may provide the best targets for intervention strategies designed to minimize the potential negative effects of pubertal maturation on internalizing symptoms in girls.     

The Impact of Pubertal Timing and Parental Control on Adolescent Problem Behaviors

This study examined the relationship among pubertal timing, parental control, and problem behaviors. There were 267 participants, whose ages ranged from 9 to 16 years. Both maternal and paternal psychological control predicted problem behaviors over and above the effects of behavioral control. For boys, early maturation and high levels of paternal psychological control, whereas for girls, on-time maturation and low levels of paternal psychological control were associated with low levels of internalizing problem behaviors. Early maturation and high levels of maternal psychological control predicted high levels of externalizing problem behaviors. The implications of these findings were discussed in terms of the detrimental effects of psychological control on adolescent wellbeing, the role that pubertal timing may or may not play during this period, and finally the need to separately examine fathers’ parenting and mothers’ parenting while investigating the impact of parental control on adolescent problem behaviors.

The Role of Early Maturation, Perceived Popularity, and Rumors in the Emergence of Internalizing Symptoms Among Adolescent Girls

Despite the widely reported link between early pubertal timing and internalizing symptoms among girls, less is known about the peer reputation of earlier maturing girls. The current study assesses whether early maturation is associated with perceived popularity and/or rumors, and whether these reputational factors help account for earlier maturing girls' vulnerability to emotional distress. Drawing on three waves of data collected from an ethnically diverse sample of middle school girls (n?=?912), hierarchical multiple regression analyses revealed that more advanced development at the start of middle school predicted peer- and teacher-reported popularity as well as increased risk of being targeted for rumors. Mediation analyses suggested that popularity among boys can put earlier developing girls at risk for rumors. Finally, rumors acted as a partial mechanism through which early maturation was associated with subsequent internalizing symptoms. Knowledge of the peer mechanisms putting earlier developing girls at risk for psychosocial maladjustment can inform intervention and prevention efforts aimed at improving adolescent well-being.     

Pubertal Development,Spare Time Activities,and Adolescent Delinquency: Testing the Contextual Amplification Hypothesis

Extensive evidence supports associations between early pubertal timing and adolescent externalizing behavior, but how and under which conditions they are linked is not fully understood. In addition, pubertal development is also characterized by variations in the relative speed at which individuals mature, but studies linking pubertal ‘tempo’ and outcomes are scarce. This study examined the mediating and moderating roles of spare time activities in associations between pubertal development and later delinquency, using data from a large (4,327 girls, 4,250 boys) longitudinal UK cohort (Avon Longitudinal Study of Parents and Children). Self-reports of Tanner stage were available from ages 9 to 14, spare time activities at age 12 and delinquency at age 15. Pubertal development was examined using latent growth models. Spare time activities were categorized using factor analyses, yielding four types (hanging out at home, hanging out outside, consumerist behavior, and sports/games), which were examined as mediators and moderators. Earlier and faster maturation predicted delinquency in boys and girls. Spare time activities partially mediated these links such that early maturing girls more often engaged in hanging out outside, which placed them at greater risk for delinquency. In addition, compared to their later and slower maturing counterparts, boys who matured earlier and faster were less likely to engage in sports/games, a spare time activity type that is linked to lower delinquency risk. No moderation effects were found. The findings extend previous research on outcomes of early maturation and show how spare time activities act as proxies between pubertal development and delinquency.     

Ethnicity,Perceived Pubertal Timing,Externalizing Behaviors,and Depressive Symptoms Among Black Adolescent Girls

An accumulation of research evidence suggests that early pubertal timing plays a significant role in girls’ behavioral and emotional problems. If early pubertal timing is a problematic event, then early developing Black girls should manifest evidence of this crisis because they tend to be the earliest to develop compared to other girls from different racial and ethnic groups. Given the inconsistent findings among studies using samples of Black girls, the present study examined the independent influence of perceived pubertal timing and age of menarche on externalizing behaviors and depressive symptoms in a nationally representative sample of Black girls (412 African American and 195 Caribbean Black; M = 15 years). Path analysis results indicated that perceived pubertal timing effects on externalizing behaviors were moderated by ethnic subgroup. Caribbean Black girls’ who perceived their development to be early engaged in more externalizing behaviors than Caribbean Black girls’ who perceived their development to be either on-time or late. Age of menarche did not significantly predict Black girls’ externalizing behaviors and depressive symptoms. The onset of menarche does not appear to be an important predictor of Black girls’ symptoms of externalizing behavior and depression. These findings suggest ethnic subgroup and perceived pubertal timing are promising factors for better understanding the adverse effects of early perceived pubertal timing among Black girls.     

The effects of pubertal timing on body image,school behavior,and deviance

Variation in the timing of pubertal maturation may result in behavioral differences among early, mid-, and late maturers. Using data from the National Health Examination Survey, a national probability sample of children and youth aged 12–17, we investigated the relationships between maturational timing and body image, school behavior, and deviance. In terms of body image, the early maturing boys were the group most satisfied with height and weight. The early maturing girls were most dissatisfied with weight, with 69% wishing to be thinner. This great dissatisfaction with weight reported by early maturing girls is probably not an affect of early maturation, but a concomitant of maturation in general. The majority of girls became dissatisfied with their weight as they matured, and females from the higher social groups were more likely to want to be thinner than females from lower groups. Thus, a normal developmental process is being viewed negatively by females and positively by males. Male early maturers more often had deviant behavior, but there were no consistent findings for girls. There was no effect of maturational timing on teacher reports of school absence, adjustment, popularity, need for discipline, or grade repetition.This research was supported by the Stanford Center for the Study of Youth Development and by the Robert Wood Johnson Foundation.Received M.D. from The Medical College of Pennsylvania.Received Ph.D. in anthropology from Stanford University.Received Ph.D. in sociology from the University of Chicago.Received M.D. from Columbia College of Physicians and Surgeons.Received Ph.D. in psychology from Harvard University.     

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.     

Early Pubertal Timing and Girls’ Problem Behavior: Integrating Two Hypotheses

Girls’ early pubertal timing has been linked in many studies to behavioral problems such as delinquency and substance use. The theoretical explanations for these links have often involved the girls’ peer relationships, but contexts have also been considered important in some explanations. By integrating two theoretical models, the peer-socialization and the contextual-amplification hypotheses, we propose a contextual framework for explaining the link between early pubertal timing and external problem behavior in girls. We hypothesize that early developing girls engage in unhealthy, dangerous, and risky behavior under contextual conditions that promote access to older friends and opposite-sex relationships. Under other conditions it is less likely. We tested this integrated hypothesis in two studies conducted in Sweden. The first was a cross-sectional study with information about school and free-time friends in a community sample (N = 284). Early pubertal timing was linked to having older, more normbreaking friends outside of school, but not in school, thus suggesting that the school context interferes early-developing girls’ selection of older peers. The second study involved both a longitudinal (N = 434) and a cross-sectional sample of girls (N = 634), where we examined a leisure setting that is known to attract delinquent youth. Results showed that early pubertal timing was most strongly linked to delinquency for girls who spent time in this context and were heavily involved with boys and peers. In sum, results from both studies supported our predictions that certain contexts would amplify the peer-socialization effect. Overall, we conclude that the integrated peer-socialization/contextual-amplification model satisfactorily explains the link between pubertal timing and external problem behavior.     

A Short-Term Longitudinal Study of Pubertal Change,Gender, and Psychological Well-Being of Mexican Early Adolescents

This study examined the role of pubertal development on depression, externalizing behavior problems, self-esteem, and body-image of 951 Mexican early adolescents. The 5th through 7th grade students were assessed at the beginning and end of the school year. The main finding of this study is that the acute experience of menarche adversely affected Mexican adolescent girls psychological well-being, most specifically in terms of depressive symptomatology. On the other hand, pubertal change in Mexican boys, as measured by voice-change, did not appear to adversely affect psychological well-being above and beyond a nonsignificant minimal and temporal readjustment and in fact had a positive effect on body-image. Results suggest that perceived maternal control, prior social–emotional adjustment, and menstrual attitudes may moderate the effects of pubertal change.     

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.     

Pubertal Maturation and African American Children’s Internalizing and Externalizing Symptoms

The association of pubertal maturation with internalizing and externalizing symptoms was examined with a sample of 867 African-American 10 – 12-year-old children. Children reported their pubertal development status and timing using a self-report questionnaire, and symptoms were assessed through diagnostic interviews with the children and their primary caregivers. Pubertal status and timing were significantly associated with children's reports of the internalizing symptoms of social anxiety disorder, generalized anxiety disorder, and major depression and with the externalizing symptoms of oppositional defiant disorder, attention deficit disorder, and conduct disorder. Pubertal development also was associated with caregivers’ reports of children's externalizing symptoms. The pubertal transition was associated with internalizing and externalizing symptoms in both boys and girls.Xiaojia Ge is Professor at the University of California, Davis.
