Peer Group Similarity in Perceptions of Pubertal Timing

Self-report measures of perceived pubertal timing correspond only weakly with clinical measures of “objective” physical development. Peer and school contexts shape adolescents’ self-perceptions of pubertal timing. The current study examined associations between perceived pubertal timing and the pubertal timing reported by nominated friends and schoolmates. Participants included 2817 adolescents (M_age = 16.6; 49 % female; 16 % Black; 20 % Hispanic) from the National Longitudinal Study of Adolescent Health. Three measures of pubertal timing were included: age-standardized ratings of body changes, comparisons of development relative to peers (relative timing), and, in females, age at menarche. It was hypothesized that relative timing, which explicitly asks adolescents to compare themselves to their peers, would be related to the age-standardized pubertal timing of nominated friends and schoolmates. Surprisingly, there were no associations between relative timing and age-standardized pubertal timing reported by peers, suggesting that pubertal self-perceptions do not fluctuate in response to the average level of development in a friend group. Instead, males were similar to nominated friends and schoolmates in age-standardized ratings of body changes, and females were similar to nominated friends in relative timing, controlling for race, ethnicity, and age. Different self-report measures of pubertal timing index different underlying constructs, and the social processes that influence adolescents’ perceptions of pubertal maturation may differ between genders.     

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.     

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.     

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.     

Developmental Markers in Adolescence: Implications for Studies of Pubertal Processes

There is inconsistency in the outcome measures of biological and psychosocial studies using measures of puberty as a predictor. For example, some studies show that maturational timing may have differential influences (positive, negative, or no effect) depending on the specific disorder, dimension of measure, and gender. Other studies have suggested that some effects may be more directly linked to pubertal stage or hormone concentrations rather than timing per se. This study outlines several conceptual and methodological issues that may be relevant to addressing these inconsistencies, in the context of examining data from a study of maturational hormones obtained from a unique longitudinal cohort of 24 girls (age 10.0 ± 1.6 years) and 36 boys (age 10.4 ± 1.6 years) in the early part of puberty, where the developmental trajectory of these hormones were tracked annually in 65% of the sample. We explored the contributions of measures of pubertal growth and sociodemographic factors on hormone concentrations. In brief, it appears that no single measure best captures the maturational processes during puberty and suggests that multiple processes are occurring in parallel. Several conceptual and methodological implications are discussed that may guide investigators in interpreting existing studies of pubertal timing and behavior as well as in conducting future studies.     

Biological and ecological factors in the expression of adolescent self-esteem

The relationship between self-esteem and pubertal maturation is examined based on results of the first two years of a six-year naturalistic longitudinal study of the ecology of self-esteem during adolescence. A random sample of 40 seventh-grade adolescents of both sexes from all socioeconomic classes was selected from a local junior high school. Four measures of pubertal maturation level were obtained for participants during each year of the study. Self-esteem was assessed by means of a repeated measures self-report technique. Each adolescent carried a beeper paging device and responded in writing to beeps that occurred on a random schedule eight times daily. Males were significantly higher in self-esteem than females. The developmental pattern for the relationship between self-esteem and pubertal maturation differed between boys and girls. Three ecological contextual variables were explored: setting, activity, and participants. Physical setting was significantly associated with level of self-esteem. Activities and participants present were not significantly predictive of self-esteem. Results are discussed in terms of the onset and timing of pubertal maturation and its influence on self-esteem.This paper is a revised version of a paper presented at the annual meeting of the American Psychological Association, Montreal, September 1–5, 1980.

Measuring physical status and timing in early adolescence: A developmental perspective

Recently, the timing-of-events model typically used for exploring adult development has been proposed for studying early adolescence and the pubertal processes occurring then. As a consequence, new interest has been generated about the psychological effects of being early, on time, or late in sexual maturation during early adolescence. A major issue has to do with the choice of maturational events to study, since puberty is a process involving numerous events, all of which have a different developmental course. This paper reviews some of the maturational events that are applicable in studying psychological effects of pubertal status and timing. Nine changes are reviewed (bone, height, weight, body fat, breast, body hair, penile, testicular, and menarcheal changes) in terms of measurement techniques, psychometric properties, and intercorrelations with other pubertal events. In addition, the usefulness of each measure for psychological research on maturational timing and status is discussed. Finally, how pubertal measures may be incorporated into a developmental perspective is considered, especially with regard to rate, duration, and asynchrony of pubertal changes.Research Interests: Girl's psychological adaptation to pubertal change, biosocial aspects of female reproductive events, development of biological and socially at risk children and adolescents.Research Interests: Reproductive endocrinology, anorexia nervosa, neuroendocrinology, adolescence.     

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.

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.     

Self-Rated Pubertal Development,Depressive Symptoms and Delinquency: Measurement Issues and Moderation by Gender and Maltreatment

This cross-sectional study examined relationships between pubertal development, depressive symptoms and delinquency in a sample of 241 males and 213 females aged 9–13 years. Four objectives were set forth for this study: (1) to examine relationships between pubertal stage or timing and depressive symptoms and delinquency; (2) to compare continuous and categorical measures of pubertal timing; (3) to examine gender as a moderator of these relationships, and (4) to examine maltreatment as a moderator of these relationships. Results indicated that mature pubertal stage and early (continuous) pubertal timing were both related to higher delinquency whereas only early pubertal timing was related to depressive symptoms. Categorical timing was not related to depressive symptoms or delinquency. Neither gender nor maltreatment were found to be moderators. These findings provide evidence against equating pubertal stage, continuous timing, and categorical timing, and highlight the need to identify possible moderators in research on pubertal development.

Measuring Puberty and Understanding Its Impact: A Longitudinal Study of Adolescent Twins

Pubertal development is an important focus of current biopsychosocial research. The Pubertal Development Scale or PDS (Petersen, Crockett, Richards, and Boxer, J. Youth Adolesc. (1988) 17: 117–133) has become a widely used measure in school-based and longitudinal research, because it incorporates several indices of pubertal development. This study reports normative data on the PDS for two population-based birth cohorts of Finnish twin boys and girls, assessed at ages 11–12 and 14. Additionally, we report longitudinal analyses of the associations between pubertal development and substance use, suggesting that the impact of pubertal timing is more complex than previously reported; associations commonly assumed between pubertal development and substance use held only for those whose developmental level, relative to peers, remained stable across follow-up. Finally, we report twin correlations for the PDS which suggest that sibling similarity for pubertal development arises from both shared genes and shared environments and that the patterns of these influences vary between sexes and across time.     

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.

Negotiating the Early Developing Body: Pubertal Timing,Body Weight,and Adolescent Girls’ Substance Use

Despite knowledge that early pubertal timing predicts adolescent girls’ substance use, it is still unclear whether this relationship persists beyond early adolescence and whether it is conditional on girls’ body weight. This study examined the moderating role of body weight in the association between early pubertal timing and adolescent girls’ substance use using three waves of data from the National Longitudinal Study of Adolescent Health. The analytic sample included 5,591 adolescent girls attending middle-schools and high-schools in the United States (ages 10–15, 71% White, 14% Black). Results indicated that early pubertal timing was associated with substance use risk but effects were attenuated after controlling for prior use. Body weight moderated the association between early pubertal timing and girls’ reported number of substances tried in middle adolescence. Body weight magnified the risk of having tried one substance, but buffered the risk of having tried three substances. Among those girls who did use substances, body weight did not moderate the relationship between early pubertal timing and heavy substance use. It is concluded that the substance use risk associated with early pubertal timing is most salient during the developmental period in adolescence when sensitivity to bodily changes may be heightened.     

Relationships Between Family Connectedness and Body Satisfaction: A Longitudinal Study of Adolescent Girls and Boys

The present study examined the longitudinal links between perceptions of family connectedness and body satisfaction in 1,774 (52% female) adolescents. Participants (10–15 years of age at Time 1) completed self-report measures at three measurement occasions separated by 1 year each. Mean group difference results showed that both body satisfaction levels and perceived levels of family connectedness decreased over 2 years for the whole sample. As expected, girls were generally less satisfied with their bodies than boys, particularly in the older cohort. Structural equation modelling was used to assess stability coefficients and cross-lagged effects, and longitudinal bidirectional effects between perceptions of family connectedness and body satisfaction were found for girls, but not for boys. This result suggests that adolescent girls’ body satisfaction is both affected by and a predictor of perceived family connectedness.     

The Developmental Pathway from Pubertal Timing to Delinquency and Sexual Activity from Early to Late Adolescence

There is strong evidence that early pubertal timing is associated with adolescent problem behaviors. However, there has been limited investigation of the mechanisms or developmental relationships. The present study examined longitudinal models incorporating pubertal timing, delinquency, and sexual activity in a sample of 454 adolescents (9–13 years old at enrollment; 47% females). Participants were seen for three assessments approximately 1 year apart. Characteristics of friendship networks (older friends, male friends, older male friends) were examined as mediators. Structural equation modeling was used to test these associations as well as temporal relationships between sexual activity and delinquency. Results showed that early pubertal timing at Time 1 was related to more sexual activity at Time 2, which was related to higher delinquency at Time 3, a trend mediation effect. None of the friendship variables mediated these associations. Gender or maltreatment status did not moderate the meditational pathways. The results also supported the temporal sequence of sexual activity preceding increases in delinquency. These findings reveal that early maturing adolescents may actively seek out opportunities to engage in sexual activity which appears to be risk for subsequent delinquency.     

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.     

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.     

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.     

Early Menarcheal Age and Risk for Later Depressive Symptomatology: The Role of Childhood Depressive Symptoms

Previous research has investigated the relationship between pubertal timing and depression in girls, with most results suggesting that earlier menarche predicts more depression in adolescence. However, few studies have controlled for the potentially confounding effects of childhood depressive symptoms. The current study uses a prospective, longitudinal sample of 1,185 girls (47.8 % Caucasian) to examine the relationships between pubertal timing, childhood depressive symptoms, and adolescent depressive symptomatology. Using multiple linear regression analyses, our results suggest that higher levels of childhood depressive symptoms and earlier menarche have independent effects on adolescent depressive symptoms. Surprisingly, childhood depressive symptomatology predicted later age of menarche, although the magnitude of this effect was small. Taken together, the results suggest that early childhood depressive symptoms and early menarche represent independent pathways to later depressive symptoms.     

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.
