The Initiation of Dating in Adolescence: The Effect of Parental Divorce. The TRAILS Study

This study examined the effect of parental divorce on the time it took adolescents to initiate their first romantic relationships. Individual differences in temperament and pubertal development and the age of the adolescent at the time of divorce were also taken into account. Hypotheses were tested using event history analysis with a sample of 1,487 Dutch adolescents. Results indicated that divorce sped up the transition to first relationship only when experienced in early adolescence. Findings are discussed in light of research on the heightened sensitivity to stress during transition periods such as the entry into adolescence.     

Pubertal Timing,Depression, and Externalizing Problems: A Framework,Review, and Examination of Gender Differences

The purpose of this report is to synthesize the existing literature on pubertal timing and (a) depression and (b) externalizing behavior within a theoretical framework of risks, transitions, and psychological development during adolescence. This review first proposes a framework for considering pubertal timing and maladaptive behavior. Next, the literature on pubertal timing and depression is discussed, followed by the literature on pubertal timing and externalizing behavior with fine distinctions being made for males and females. Additionally, mediating and moderating variables are reviewed in an effort to understand mechanisms by which timing of puberty and maladjustment may operate or risk factors that may amplify the detrimental consequences of the pubertal transition. Finally, conclusions and future directions are proposed.     

Accentuation of Individual Differences in Social Competence During the Transition to Adolescence

Using a sample of individuals (277 males, 315 females) studied since birth in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, the present study investigated how early pubertal maturation and school transition alter youth trajectories of social competence during the transition to adolescence. Social competence showed strong continuity, with the most socially competent children remaining so in adolescence. Early pubertal maturation and school transitions accentuate individual differences, increasing social competence among more competent youth, but further diminishing social competence among less competent individuals. In essence, facing challenges that require social competence may further separate competent individuals from less competent peers. Thus, the psychosocially rich become richer, while the psychosocially poor become poorer.     

The Relation between Puberty and Psychological Distress in Adolescent Boys

This longitudinal study examined the relation between puberty, as measured by both pubertal status and timing, and adjustment problems, as measured by externalized hostile feelings and internalized distress symptoms, among adolescent males in grades 7 through 10. The results showed that boys who were physically more developed in grade 7, compared with their less physically developed peers, manifested more externalized hostile feelings and internalized distress symptoms in grades 8 through 10. Pubertal timing was significantly related to both internalized distress and externalized hostile feelings. This relation remained statistically significant, even after controlling for grade 7 maladjustment symptoms and concurrent stressful life events. Several significant interaction effects emerged between pubertal timing and concurrent stressful life events. The significant long‐term effect of the pubertal transition, independent of stressful life experiences and symptom continuity, suggests that the past undifferentiated view of the favorable influence of early maturation on males needs to be modified.     

Puberty and Transdiagnostic Risks for Mental Health

Puberty in girls represents a notable period of vulnerability for different psychological disorders. The research literature has primarily considered external and contextual factors that might explain these rises in symptomatology. In the present study, we investigate relations of pubertal status and timing with individual cognitive, emotional, and behavioral tendencies, commonly identified as transdiagnostic processes, in a sample of N = 228 girls (M_age = 11.75 years). We also test whether these transdiagnostic processes mediate associations of pubertal status and pubertal timing with depressive symptoms. Results support greater endorsement of rumination, co‐rumination, negative urgency, and both anxious and angry rejection sensitivity in girls with more advanced pubertal status, as well as in girls with early pubertal timing. Higher levels of transdiagnostic processes fully mediated associations of pubertal status and timing with depressive symptoms at significant and marginally significant levels, respectively. Although the data are cross‐sectional, these findings offer promising preliminary evidence that transdiagnostic processes represent an important mental health risk in early adolescent girls.     

The Role of Pubertal Timing in What Adolescent Boys Do Online

The aim of this study was to investigate associations between pubertal timing and boys' Internet use, particularly their viewing of pornography. We used a sample comprising of 97 boys in grade 8 (M age, 14.22 years) from two schools in a medium‐sized Swedish town. This age should be optimal for differentiating early, on‐time, and later‐maturing boys. Boys responded to self‐report questionnaires on their Internet use and pubertal timing. Early, on‐time, and late‐maturing boys did not differ in terms of most Internet activities. However, early maturers reported downloading and viewing pornography more often than the other boys did (p<.001). The findings build on previous research on the link between pubertal timing and sexual behavior in adolescence. Moreover, they help further understanding of the behavioral implications of boys' pubertal timing.     

Pubertal Timing and Tempo: Associations With Childhood Maltreatment

This study examined pubertal timing and tempo in a sample of 445 adolescents (53% male), using both variable‐centered (latent growth curve) and person‐centered (latent class) approaches, to discern the pubertal development trajectories associated with the experience of maltreatment. Results from the variable‐centered analyses indicated a slower initial tempo that increased later for boys who had experienced neglect. The person‐centered results indicated three classes for boys that mainly differentiated tempo effects and two classes for girls primarily distinguishing timing differences. For girls, sexual abuse predicted membership in an earlier pubertal timing class. These findings enhance our knowledge of the variability in pubertal development as well as gender differences in maltreatment types that may alter pubertal timing and tempo.     

Peripubertal Girls' Romantic and Platonic Involvement With Boys: Associations With Body Image and Depression Symptoms

This study explored the relationship of both romantic and platonic involvement with boys, as well as pubertal status, to body image and depression symptoms among an ethnically diverse sample of sixth‐grade girls. Participants were 157 early adolescent girls (ages 10–13) who completed self‐report measures designed to assess girls' level of involvement with boys, pubertal status, and psychological adjustment. Girls' degree of romantic involvement was positively associated with higher depression scores. More advanced pubertal status was associated with both lower body image satisfaction and higher depression scores. A significant interaction between platonic involvement and pubertal status emerged. Girls who were less sexually mature but who also reported more platonic involvement with boys reported greater body image satisfaction. These findings suggest that the type of involvement with boys (romantic vs. platonic) and a girl's pubertal status influence psychological adjustment.     

Genetic and Environmental Influences on Pubertal Timing: Results From Two National Sibling Studies

This study examined genetic and environmental effects on individual variation in pubertal timing using two national samples of siblings from the Nonshared Environment of Adolescent Development (NEAD) and the National Longitudinal Study of Adolescent Health (Add Health). In each sample, female and male siblings with different degrees of genetic relatedness, i.e., monozygotic twins, dizygotic twins, full siblings, half siblings, and unrelated siblings in blended families, were assessed. Timing of pubertal development was measured by age-adjusted self-report measures of the Pubertal Development Scale in NEAD and a four-item scale of pubertal development in the Add Health. The results indicated that both genetic and environmental influences play an important role in determining the relative timing of pubertal development for both boys and girls.     

The Impact of Pubertal Timing on Adolescents’ Alcohol Use

The relation between pubertal timing and alcohol use was investigated in a nationally representative sample (N= 4,686) of junior high school students who were followed up 2 years later (N= 3,862). Information regarding pubertal timing and status, sex‐role identification, number of alcohol intoxications, substance use, sexual behavior, friends’ alcohol use, and involvement in other types of problem behaviors was obtained. The results showed that early timing of pubertal development correlated with number of alcohol intoxications and number of units consumed on each occasion, and, to a lesser degree, with the frequency of alcohol use. Moreover, correlations were stronger among males than among females. Substantial parts of the association between pubertal timing and alcohol intoxications were mediated through friends’ problem behavior. Pubertal timing predicted alcohol use at follow‐up, but the effect was mostly due to increased alcohol intoxications at initial testing.     

Trajectories of Depressed Mood From Early Adolescence to Young Adulthood: The Effects of Pubertal Timing and Adolescent Dating

The effects of pubertal timing and adolescent dating on trajectories of depressed mood from early adolescence to young adulthood were examined among youths who participated in the National Longitudinal Study of Adolescent Health. Results showed that for both boys and girls, the trajectories of depressed mood between the ages of 12 and 23 took an inverse U‐shape with its peak in mid‐adolescence. Furthermore, pubertal timing was a significant predictor of depressed mood at age 12. The pubertal timing effect was nonlinear, suggesting that at age 12, early and late maturing youths were at risk of experiencing elevated levels of depressed mood. The adverse effect of off‐time maturation gradually dissipated over time. Moreover, in early adolescence, teenagers, particularly girls, were adversely affected by dating, and off‐time physical maturation exacerbated the negative effects of dating. However, the interactive effect of dating and pubertal timing gradually decreased with age. Our findings underscore the importance of examining junctures of biological and social challenges in adolescence to gain better understandings of young people's emotional experiences over time.     

Risk Factors of Sexual Harassment by Peers: A Longitudinal Investigation of African American and European American Adolescents

The present research explores risk factors for, and longitudinal associations of, sexual harassment by peers during adolescence. Eight‐hundred and seventy‐two African American and European American adolescents (65.4% African American, 51.1% females) were assessed during the summer after the eighth grade (mean age=14.2 years) and then again in the 11th grade (mean age=17.1 years). At the first assessment, adolescents were asked about their experiences with sexual harassment, their psychological reactions to sexual harassment, and also about their peer relationships, perceived pubertal timing, problem behavior, and mental health. At the second assessment, adolescents reported on their problem behavior and mental health. In general, youth who associated with peers who were involved in problem behavior were at risk for victimization. Among females, those who perceived themselves to be experiencing early pubertal development were also at risk. Additionally, for some adolescents, sexual harassment predicted later adjustment difficulties.     

Conceptualizing Puberty as a Window of Opportunity for Impacting Health and Well‐Being Across the Life Span

We promote the perspective that puberty, a separate biological process embedded in adolescence, is a “window of opportunity” for understanding and impacting health and development. First, we include a brief overview of pubertal change. Second, we propose a critical role for puberty in shaping life span health due to its connections with early life precursors, health issues and risks emerging during puberty, and health in young adulthood and beyond. Next, we discuss the importance of puberty measures in developmental research and suggest ways to make the science of puberty an important standalone research entity, as well as an essential component of studies conducted during adolescence. Finally, we discuss measurement issues, novel theoretical models of puberty, and the necessity of adopting an interdisciplinary perspective in research on puberty and in adolescence more broadly.     

Brief Report: The Role of Ego Development in Psychosocial Adjustment Among Boys With Delayed Puberty

This study examined the role of ego development, as measured with the Washington University sentence completion test, in the relationship between pubertal maturation and psychosocial adjustment (self-image and depression) in adolescent boys. The data consisted of 73 boys between 14 and 16 years of age. The results indicated that late maturing boys were also psychologically more immature, and that they experienced negative feelings about sexuality. Additionally, higher ego development was associated with elevated levels of anxiety and depression among late maturing boys. In boys with average pubertal maturation, higher ego development was associated with lower levels of anxiety and depression.     

Linking Childhood Maltreatment With Girls' Internalizing Symptoms: Early Puberty as a Tipping Point

Earlier physical maturation may often be preceded by a range of adversities and life stressors. This study investigates childhood maltreatment, internalizing symptoms, and pubertal timing in girls residing in foster care (N = 100, M = 11.54 years old at Time 1). Girls were assessed at two time points 2 years apart. There were no direct effects of maltreatment on internalizing symptoms; rather, childhood sexual abuse predicted earlier pubertal development which, in turn, was associated with higher levels of internalizing symptoms concurrently and longitudinally. This distinctive role for early pubertal timing suggests that the heightened sexual circumstances of puberty may be especially disturbing for girls whose lives have already been disrupted by inappropriate and unwanted sexual experiences.     

Network social capital as an outcome of social movement mobilization: Using the position generator as an indicator of social network diversity

In the social mobility literature, the position generator (PG) has been used to examine the relationship between the structural location of individuals, and outcomes such as obtaining a high status job. Diversity of occupational ties (as measured by the PG) is also a significant predictor of an individual's cultural capital. A great deal of work has also been done in the field of social movements examining the relationship between networks and mobilization. However, only limited attention has been given to the position generator in this literature. Also, while past research has demonstrated that prior network ties to activists is one of the most important predictors of current activism, relatively little research has been devoted to examining network structure as an outcome of activism. The present paper builds upon these insights by utilizing data collected with the position generator on a sample of environmental movement members, and examining the relationship between individual activism (as an independent variable) and diversity of occupational ties (as a dependent variable). The result of key theoretical significance is that those who are more active in the environmental movement develop a greater diversity of occupational ties to other environmentalists. Results suggest that this process occurs over time. These findings provide evidence that social capital (as indicated by network diversity) is one outcome of social movement mobilization.     

Sexually Explicit Websites and Sexual Initiation: Reciprocal Relationships and the Moderating Role of Pubertal Status

A two‐wave panel study was conducted among adolescents (Mean age = 14.78; N = 639) to examine the relationship between using sexually explicit websites and sexual initiation with particular attention to adolescents' pubertal status. Structural equation modeling and logistic regression analysis indicated that frequent users of sexually explicit websites were five times more likely to initiate sexual intercourse than nonusers. Pubertal status moderated this relationship: an increased likelihood to initiate sex was found among adolescents in an early pubertal stage who frequently viewed sexually explicit websites. However, a lower likelihood to initiate sex was found among adolescents in an advanced pubertal stage. The possibility of a reciprocal relationship was also examined but was not supported.     

Maternal Regulation of Daughters' Emotion During Conflicts From Early to Mid‐Adolescence

Primary caregivers play an important role in emotion socialization. Real‐time mother–daughter emotion socialization was examined in 45 mother–daughter dyads with early‐adolescent daughters (age M = 11.80, SD = .27) at the first observation point. Maternal supportive emotion regulation and daughters' emotions were coded during two conflict discussions, 2 years apart. With multilevel survival analysis, the likelihood of maternal supportiveness was predicted both over time, between early and mid‐adolescence, and by daughters' pubertal status. Mothers were more likely to respond to daughters' negative and positive emotions with supportiveness for daughters whose pubertal maturation occurred relatively early. Results suggest that mothers adjust their socialization of daughters' emotions according to their daughters' pubertal development.     

The influence of parents’ social capital on their children’s transition to vocational training in Germany

This study investigates the up-to-now strongly underexplored role of parents’ social capital in the school-to-work transition of adolescents. We base our empirical analyses on unique longitudinal largescale data from the German National Educational Panel Study. Parents’ social capital is measured with a position generator. Results show that adolescents with lower secondary education have better chances of finding an apprenticeship in a company if their parents know many persons with lower-status occupations for which vocational training is sufficient. This is especially the case for parents’ social contacts that have occupations in which many adolescents with lower secondary education are being trained in a company. The contrary is true for adolescents whose parents know many persons with higher-status occupations. Parents’ social networks do not show any effects on the quality of these apprenticeships or on the probability of entering school-based vocational training. Overall, our results indicate that parents’ social networks are important for a smooth school-to-work transition of their children. Moreover, our analyses confirm the idea that social capital is goal and labour market segment specific.     

Polygenic Influences on Pubertal Timing and Tempo and Depressive Symptoms in Boys and Girls

This study used polygenic scoring (PGS) to test whether puberty‐related genes were correlated with depressive symptoms, and whether there were indirect effects through pubertal maturation. The sample included 8,795 adolescents from the Avon Longitudinal Study of Parents and Children (measures of puberty drawn ages 8–17 years; of depressive symptoms at age 16.5 years). The PGS (derived from a genome‐wide meta‐analysis of later age at menarche) predicted boys’ and girls’ later pubertal timing, boys’ slower gonadal development, and girls’ faster breast development. Earlier perceived breast development timing predicted more depressive symptoms in girls. Findings support shared genetic underpinnings for boys’ and girls' puberty, contributing to multiple pubertal phenotypes with differences in how these genetic variants affect boys' and girls' development.
