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.     

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.     

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.

A Longitudinal Investigation of Associations Between Boys’ Pubertal Timing and Adult Behavioral Health and Well-Being

To extend research linking pubertal timing and adolescent health outcomes, this study examines boys’ pubertal timing and subsequent interpersonal success and health behaviors in mid adulthood. Past research has shown that boys’ pubertal timing is associated with both positive and negative developmental outcomes in the short term, and so it is unclear how pubertal timing is consequential for adjustment across the long term. Data from 460 boys from the Terman Life-Cycle Study were examined over a 39-year period to relate age of pubertal onset to later marital success, career success, and adult health behaviors. Boys who reached puberty earlier than their peers achieved greater success in their careers and experienced more satisfaction in their marriages. Early-developing boys were not found to be more likely than their peers to smoke cigarettes or drink alcohol as adults. Findings are discussed in terms of the importance of pubertal timing for life-span development.Keiko Taga is a doctoral student at the Department of Psychology at University of California, Riverside.

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.

Pubertal Timing and Depressive Symptoms in Early Adolescents: The Roles of Romantic Competence and Romantic Experiences

In spite of the large literature supporting the link between early pubertal timing and depression in adolescent girls, there are some exceptions. This suggests that there may be factors that interact with pubertal timing, increasing risk for depression in some girls, but not others. This study examined two such factors, romantic competence and romantic experiences, and their role in the cross-sectional and longitudinal associations between pubertal timing and depressive symptoms among 83 early adolescent females (89% Caucasian). For on-time maturing girls (but not for early- or late-), lower levels of competence were associated with higher levels of depressive symptoms concurrently, but not longitudinally. In addition, for on-time maturing girls, more romantic experiences were associated with higher levels of depressive symptoms both concurrently and longitudinally. The discussion focused on the need for greater conceptual and empirical clarity regarding the pubertal timing-depression association and its potential moderators.

The Influence of Pubertal Timing on Alcohol Use and Heavy Drinking Trajectories

Early pubertal timing has been associated with increased alcohol use, drunkenness, and alcohol use disorders in both boys and girls during adolescence. It is not clear, however, whether the effect of early pubertal timing persists into late adolescence and young adulthood, whether its effect differs by gender, and if contextual factors (e.g., peer alcohol use) amplify such effect. This study attempts to address these questions by examining the trajectories of alcohol use and heavy drinking from early adolescence to young adulthood in males and females using data from the National Longitudinal Study of Adolescent Health (Add Health). Results show that for both males and females, early pubertal timing was associated with higher alcohol use and heavy drinking trajectories. These effects persisted into young adulthood and were found to be stronger for males than for females. Moreover, there was a significant interaction effect between friends’ drinking and pubertal timing on alcohol use and heavy drinking trajectories; but the interaction effect also differed for males and females. These findings suggest that early pubertal timing is a risk factor for alcohol use and has long-term implication for individuals’ health.

He is particularly interested in developmental pathways leading to substance use and affective disorders and how different contexts influence these developmental pathways.

Distinctiveness of Adolescent and Emerging Adult Romantic Relationship Features in Predicting Externalizing Behavior Problems

Romantic relationship involvement has repeatedly been associated with the incidence of externalizing behavior problems, but little is known about the nature and developmental significance of this relation. The current study extends previous research by investigating whether and through what processes romantic relationships distinctively predict externalizing behavior problems during adolescence compared to emerging adulthood. Data came from the Minnesota Longitudinal Study of Parents and Children. As predicted, higher levels of romantic relationship security at 16 years were associated with lower levels of externalizing behavior problems during both adolescence and emerging adulthood, but this inverse relation was stronger for emerging adults than for adolescents. This relation was not attributable either to earlier quality of family and peer relationships or emerging adulthood competence. Thus, security of romantic relationships may become increasingly predictive of individual differences in externalizing behavior problems as individuals move from adolescence to emerging adulthood.

Effects of Pubertal Timing on Communication Behaviors and Stress Reactivity in Young Women During Conflict Discussions with their Mothers

Individuation, a process whereby adolescents gain autonomy from their parents while maintaining emotional relatedness, is displayed by characteristic styles of verbal exchanges. Negotiating this developmental transition is often stressful for adolescents and their parents. This study deals with the association between pubertal timing, communication behaviors, and stress reactivity assessed during young females’ conflict discussions with their mothers. A sample of N = 32 girls (age 9–13, T1) was grouped by pubertal timing. Years later (age 17–22, T2) they were followed up and videotapes of daughter–mother conflict discussions were evaluated. Salivary alpha-amylase was used to assess the stress reactivity. Results revealed that young women who had entered puberty early were higher in striving for control and separation in interactions with their mothers, and displayed higher stress levels. These results pointed to less successful individuation in late adolescence/young adulthood compared to on-time and late maturing age mates.

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.

Examining Temporal Associations Between School Connectedness and Early Adolescent Adjustment

This study examined (a) the associations between school connectedness and early adolescent adjustment problems over a 1 year period and (b) the equivalence of these associations across gender. Five hundred middle school students (53.4% female), initially in the 6th and 7th grades, participated in the two-wave study. Results from two-group cross-lagged panel analyses were consistent across boys’ and girls’ data. After controlling for baseline levels of adjustment problems, school connectedness predicted lower levels of early adolescent conduct problems 1 year later. Regarding the opposite direction of associations, and even after baseline levels of school connectedness were taken into account, conduct problems predicted lower levels of subsequent school connectedness. There were no cross-lagged associations between depressive symptoms and school connectedness, although elevated levels of baseline depressive symptoms predicted higher levels of subsequent conduct problems. Findings elaborate previous research by demonstrating that early adolescents actively shape the middle school environment.

Adolescent Women's Sports Involvement and Sexual Behavior/Health: A Process-Level Investigation

This multimethod study explored the promising link between organized sports involvement during the high school years and sexual behavior/health among 176 adolescent women. Using more sensitive and appropriate measures than those in existing studies and directed, in part, by cultural resource theory, this study helped to fill a gap in the literature by exploring potential mediators (i.e., functional body orientation and self-empowerment/efficacy) of that link. Results from the quantitative data indicated that adolescent women's involvement in organized team sports was favorably associated with each of the following: (a) sexual-risk-taking behavior, (b) sexual/reproductive health-seeking behavior, and (c) sexual/reproductive health. In addition, both functional body orientation and self-empowerment/efficacy emerged as mediators in the associations between sports involvement and sexual behavior/health among adolescent women. Content analysis of participant responses to open-ended items provided further confirmation of those mediating effects. Implications for the development of sports and community programs focused on the prevention of teenage pregnancy and STDs are discussed.     

Adolescent Problem Behavior and Depressed Mood: Risk and Protection Within and Across Social Contexts

This study examined risk and protection for adolescent problem behavior and depressive symptomatology in an average-risk sample of 11th graders. Using a socioecological perspective, we aggregated risk factors for adolescent problem behavior and depressed mood by 3 social contexts: i.e., family and peer contexts, and a context comprising the most important nonparental adult (VIP) in respondents' lives. Protective factors associated with these 3 contexts were also included in the analyses. We tested separate models (including outcome-specific risk and protective factors) for predicting problem behaviors and depressive symptoms; the models demonstrated divergent validity. Risk and protective factors accounted for 49% of the variance in problem behavior and 49% in depressive symptoms. Tests of interactions between risk-aggregates and protective factors yielded several significant cross-context buffering effects in the problem behavior model, but none in the depressive symptoms model. Parents' and VIP's perceived sanctions buffered adolescents against high risk for problem behavior emanating from the peer context. Additionally, perceived peers' sanctions buffered youths against risk emanating from each of the 3 contexts.     

The Contribution of Organized Youth Sport to Antisocial and Prosocial Behavior in Adolescent Athletes

In this study, we investigated the contribution of organized youth sport to antisocial and prosocial behavior in adolescent athletes. The sample consisted of N=260 male and female soccer players and competitive swimmers, 12 to 18 years of age. Multilevel regression analysis revealed that 8% of the variance in antisocial behavior and 7% of the variance in prosocial behavior could be attributed to characteristics of the sporting environment. Results suggested that coaches who maintain good relationships with their athletes reduce antisocial behavior, and that exposure to relatively high levels of sociomoral reasoning within the immediate context of sporting activities promotes prosocial behavior. These results point to specific aspects of adolescents’ participation in sport that can be used to realize the educational potential of organized youth sport.

Adolescent-Mother Agreement about Adolescent Problem Behaviors: Direction and Predictors of Disagreement

Correlations between adolescent and parent reports of adolescent problems are low in magnitude. In community samples adolescents tend to report more problems than parents and in clinical samples adolescents tend to report fewer problems than parents. Indices of agreement may be biased if some adolescents in a given sample report more problems and others report fewer problems than parents. In the current study, order and mean agreement between adolescent and maternal reports of adolescent internalizing and externalizing problems, taking into account the direction of disagreement, was examined in a community sample of 133 young adolescents and their mothers. Two-thirds to three-quarters of adolescents reported more problems than mothers. Accounting for the direction of discrepancies resulted in improved agreement between adolescents and mothers and differing patterns of predictors of discrepancies. Additionally, the results demonstrate the need to control for relations between adolescent-reported problems and discrepancies when exploring predictors of discrepancies. Erin T.

Perceived Peer Behavior and the Timing of Sexual Debut in Rwanda: A Survival Analysis of Youth Data

This paper uses survival methods to assess the relationship between perceived peer behavior and the timing of first sex among Rwandan youth. The data derive from a 2001 survey among youth aged 15–24 years in four provinces: Kigali Ville, Butare, Kibuye, and Umutara. A total of 1327 male and female youth were interviewed through a structured questionnaire that includes questions on sexual attitudes and behaviors. The findings showed that the perception that peers are sexually active is associated with increased likelihood of experiencing early sexual debut. For both sexes, the relationship between perceived peer behavior and the timing of first sex is stronger in young adulthood than in late adolescence. Among female youth, the presence of the father appears to weaken the role of perceived peer behavior. A similar tendency is not found for male youth.     

Understanding the Association Between Maltreatment History and Adolescent Risk Behavior by Examining Popularity Motivations and Peer Group Control

The purpose of the present study was to examine how peer group processes of pressure and control and individual motivations for popularity would add to, and moderate the relationship between, childhood maltreatment and risky behavior in adolescence. A total of 1558 youth (804 girls) from three high schools in Ontario, Canada (M age = 15.02 years, SD = .86) reported on their alcohol use, delinquent behavior, childhood experiences of physical and emotional maltreatment and neglect, peer group processes involving control and individual popularity motivations. Regression analyses showed that, beyond the significant contributions of childhood maltreatment, peer group control predicted risky alcohol use and delinquent behavior. Peer group control and popularity motivations exacerbated the negative effect of physical maltreatment on delinquent behavior. Boys’ experiences of peer group control were more strongly linked to alcohol use and delinquent behavior than girls’. These results suggest that there is a significant window of opportunity during adolescence where the peer group context can exacerbate or buffer childhood experiences.

Participation in Extracurricular Activities and Adolescent Adjustment: Cross-Sectional and Longitudinal Findings

This study extends previous understanding of the association between adolescent extracurricular activity participation and adjustment by asking whether participation in school-based extracurricular activities is associated with lower substance use and depression, higher grades and academic aspirations, and more positive attitude toward school. In addition, it examines the role of life events stress and time spent in activities as potential moderators of the association. Data come from an ethnically diverse sample of adolescents from 6 California highschools (N = 3,761). Cross-sectional results suggest participation is associated with more positive adolescent outcomes for all variables except alcohol use and depression, controlling for gender, ethnicity, and grade. Longitudinal analyses are consistent with these findings. Cumulative participation over a 3-year period predicts adolescent outcomes controlling for both Time 1 outcomes and demographic characteristics. In addition, within-person analyses reveal year-to-year covariation of participation and positive outcomes.
