Early pubertal maturation is associated with earlier contact with the juvenile justice system. In two studies (Total N = 782), we examined whether youth presumed to have committed a crime and who appear physically older than their chronological age were held to different standards of legal responsibility while accounting for race and sex. Participants read a vignette detailing situations in which a crime was committed and decided whether to call the police (Study 1) or make sentencing recommendations (Study 2). Participants were more likely to call the police on youth who appeared more physically developed and on boys. Less visibly mature youth and girls were assigned behavioral explanations that deemphasized agency. White youth were sentenced to more hours of community service than Black youth. We discuss potential implications of these findings in real‐world contexts such as police decision‐making. [ABSTRACT FROM AUTHOR]

The present study investigates the underlying cognitive, social, and behavioral tendencies that may explain why some girls are more likely to perceive the adolescent transition as disrupting and difficult, otherwise characterized as role disruption. It was hypothesized that individual differences in rumination, rejection sensitivity, peer problems, and pubertal status would contribute to why some girls perceived more role disruption during the transition from childhood to adolescence, and that girls who reported more role disruption would be at increased risk for subsequent depression. N = 188 girls (Mage = 11.70 years) reported on their level of pubertal development, rumination, rejection sensitivity, peer problems, and depressive symptoms at three time points approximately 4 months apart. Structural equation modeling results suggested that baseline levels of rumination and angry rejection sensitivity explained perceptions of role disruption at Time 2 more than overall levels of pubertal development, and that greater role disruption predicted subsequent depressive symptoms at Time 3. These findings highlight the importance of individual tendencies in understanding who will find early adolescence challenging. [ABSTRACT FROM AUTHOR]

In the past half‐century, developmentalists have produced a rich, diverse, and substantial literature on the psychology of puberty, establishing the transition from childhood to adolescence as one of the most pivotal phases of life. In this article, we identify three domains of research on puberty that are prime for new scientific inquiry: (a) hormones, (b) cohort trends, and (c) alternative measures and methods. Although these areas differ from each other in concept, scientific implementation, and ramifications for research, they are alike in their potential to advance developmental science and to strengthen theories, concepts, and understanding of this period of psychological change.

Beginning at puberty, prevalence of depression in females rises dramatically. The physical changes of puberty coincide with a period of social flux, during which relationships become less stable and more prone to conflict. While this social upheaval is normatively distressing for girls, it may be especially so for girls with cognitive styles that leave them more susceptible to depression. The present study investigated depressive symptoms at two time points during early pubertal maturation. N = 110 girls (M age = 11.57, SD = 0.98) reported on depressive symptomology, pubertal maturation, ruminative coping style, frequency of peer conflict, and rejection sensitivity. Multivariate analyses suggest more advanced pubertal development and greater rejection sensitivity at Time 1 predicted higher levels of depressive symptoms at Time 2, after accounting for baseline levels of depressive symptoms and all other social and cognitive correlates of depression. This effect was also found in early maturing girls. Menarche status was not significant. Since menarche occurs toward the end of puberty, results suggest that risk for worsening depression is not associated with completing puberty, or with menstruation itself. Rather, increases in depressive symptoms seem to be associated with physical changes that emerge early in the pubertal transition, especially for early maturing girls, paired with anticipatory concerns about social rejection.

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 = 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.

ABSTRACT Objective Puberty is an important period of risk for the onset of eating pathology in adolescent females. This review focuses on changes in reproductive hormones during puberty as one specific psychopathogenic mechanism. Method Studies of puberty and eating disorder-related phenotypes were identified using search databases and the reference sections of previous literature. Results Correlational studies of adult women and experimental studies of animals provide evidence for the effects of reproductive hormones on eating disorder symptoms. Very few studies of puberty, however, have directly measured or tested the effects of hormonal change in samples of human adolescents. Commonly used measures of pubertal development, such as menarche or self-reported pubertal status, are relatively poor indicators of individual differences in hormones. The extent to which puberty-related hormonal change accounts for elevated risk for disordered eating remains unclear. Discussion Future research is necessary to elucidate the specific relations between hormonal change during puberty and risk for disordered eating. In particular, there is a need for longitudinal studies with multivariate measurement of pubertal development, including direct measures of change in reproductive hormones. © 2014 Wiley Periodicals, Inc.

• A new framework exploring sensitivity and reactivity to rejection together. • Rash reactions to distress of rejection perpetuate relational stress in adolescents. • Individual and contextual differences explain a continuum of responses to rejection. • Developmental considerations and implications for research and practice are discussed. This paper poses a novel theoretical framework for a developmentally-informed mechanism explaining how adolescents who are highly sensitive and reactive to rejection may respond to interpersonal stress in ways that ultimately perpetuate relational difficulties. Specifically, heightened distress from rejection is proposed to activate impulsive reactions that immediately modulate the negative emotions from rejection, but which are socially aversive and thus often come at the expense of long-term relational harmony. We start by exploring the overlap of two dispositions: a hyper-sensitivity to rejection and an escalated reactivity to negative affect. We then trace distal factors underlying the development of both dispositions, the mechanisms through which the convergent effects of these dispositions produce socially aversive responses, and the individual and contextual differences that influence this process and explain the continuum of rash responses to rejection. The developmental and clinical importance of considering sensitivity and reactivity to rejection concurrently is emphasized, with directions for future research. [ABSTRACT FROM AUTHOR]

Adolescent dating and sexual activity are consistently associated with risk for depression, yet the pathways underlying this association remain uncertain. Using data on 1,551 sibling pairs (ages 13-18) from the National Longitudinal Study of Adolescent Health, the current study utilized a sibling comparison design to assess whether adolescent dating, sexual intercourse with a romantic partner, and sexual intercourse with a nonromantic partner were associated with higher levels of depressive symptoms independent of familial factors. Results indicated that adolescent dating, in and of itself, was not associated with depressive symptoms. The association between depressive symptoms and sexual activity with a romantic partner was fully accounted for by between-family genetic and shared environmental confounds. In contrast, sexual activity with a nonromantic partner was significantly associated with both mean levels of depressive symptoms and clinically severe depression, even within sibling dyads. This relationship was greater for younger adolescents (<15 years). These results are consistent with a growing body of research demonstrating that relationship contexts may be critical moderators of the psychosocial aspects of adolescent sexual experiences.

The physical changes of puberty coincide with an increase in the salience of peer relationships and a growing risk for depression and other forms of psychopathology. Previously, we reported that pubertal tempo, defined as a child's rate of intraindividual change in pubertal status (measured using parent- reported Tanner stages; Marshall & Tanner, 1970), was associated with changes in boys-'-but not girls'--depressive symptoms over and above effects explained by pubertal timing (Mendle, Harden, Brooks-Gunn, & Graber, 2010). The present study extends this previous research by examining changes in the quality of peer relationships in the association between individual differences in pubertal development and change in boys' depressive symptoms. Boys (N = 128. M = 9.61 years, SD = 0.70, at Time 1) were recruited from public schools and assessed annually for 4 years. Results from latent growth curve models indicated that earlier pubertal timing and more rapid pubertal tempo were associated with greater decrements in the quality of boys' peer relationships. After accounting for the association between change in peer relationships and depressive symptoms, the direct effects of pubertal timing and tempo on depressive symptoms were no longer significant. These results highlight a multifaceted approach to studying puberty and emphasize how social mechanisms may intersect with biological risk to produce psychological distress. [ABSTRACT FROM AUTHOR]

Menarche is a discrete, transitional event that holds considerable personal, social, biological, and developmental significance. The present longitudinal study examined both the transition and timing of menarche on the trajectory of anxiety in girls with histories of childhood maltreatment ( N = 93; 63% European American, 14% multiracial, 10% Latino, 9% African American, and 4% Native American). We hypothesized that because menarche is a novel, unfamiliar experience, girls would show greater anxiety around the time of menarche. The anxiety-provoking nature of menarche may be accentuated among earlier-maturing girls and girls with histories of childhood sexual abuse. Results indicated that earlier-maturing girls were more anxious in the pre- and peri-menarche periods than their later-maturing peers; however, their anxiety declined after menarche. Childhood sexual abuse was associated with heightened anxiety throughout this transition. The developmental significance of the timing and transition of menarche in relation to childhood sexual abuse and anxiety is discussed. [ABSTRACT FROM AUTHOR]

Academic achievement and cognitive ability have been shown to predict later age at first sexual intercourse. Using a sample of 536 same-sex twin pairs who were followed longitudinally from adolescence to early adulthood, this study tested whether relations between intelligence, academic achievement, and age at first sex were due to unmeasured genetic and environmental differences between families. Twins who differed in their intelligence or their academic achievement did not differ in their age at first sex. Rather, the association between intelligence and age at first sex could be attributed entirely to unmeasured environmental differences between families, whereas the association between academic achievement and age at first sex could be attributed entirely to genetic factors.

The relation between timing of first sex and later delinquency was examined using a genetically informed sample of 534 same-sex twin pairs from the National Longitudinal Study of Adolescent Health, who were assessed at three time points over a 7-year interval. Genetic and environmental differences between families were found to account for the association between earlier age at first sex and increases in delinquency. After controlling for these genetic and environmental confounds using a quasi-experimental design, earlier age at first sex predicted lower levels of delinquency in early adulthood. The current study is contrasted with previous research with non-genetically informative samples, including Armour and Haynie (, Journal of Youth and Adolescence, 36, 141–152). Results suggest a more nuanced perspective on the meaning and consequences of adolescent sexuality than is commonly put forth in the literature. [ABSTRACT FROM AUTHOR]

Girls who grow up in households with an unrelated adult male reach menarche earlier than peers, a finding hypothesized to be an evolutionary strategy for families under stress. The authors tested the alternative hypothesis that nonrandom selection into stepfathering due to shared environmental and/or genetic predispositions Creates a spurious relation between stepfathering and early menarche. Using the unique controls for genetic and shared environmental experiences offered by the children-of-twins design, the authors found that cousins discordant for stepfathering did not differ in age of menarche. Moreover, controlling for mother's age of menarche eliminated differences in menarcheal age associated with stepfathering in unrelated girls. These findings strongly suggest selection, and not causation, accounts for the relationship between stepfathering and early menarche. [ABSTRACT FROM AUTHOR]

As cancer remains the leading disease-related cause of death in adolescence, designers must consider the influence of health facility design on social support and quality of life, while considering the changing psychosocial needs of adolescents and young adults (AYAs). Both the stress of treatment and the environment in which treatment occurs can influence AYAs during a time of significant social, biological, and cognitive developmental transitions. A questionnaire developed and provided to 104 AYA-aged survivors of AYA cancer revealed significant inadequacies across 22 features of the cancer treatment environment. Results of a regression analysis suggest a significant relationship between adequacy of the built environment, social support, AYA-specific resources, and health-related quality of life. Recommendations are provided for the design of an inpatient or outpatient cancer facility for young people, such that designers must create space to balance desired and achieved social interaction. • Cancer facilities for adolescents and young adults (AYAs) are significantly inadequate. • The built environment, social support, and AYA resources can help predict quality of life. • AYAs may benefit from environments providing choice, control, and privacy. • Designers should consider a spectrum of public to private spaces.

Though commonly discussed in regard to risky behavior and psychopathology, negative urgency should also play a role in common behaviors and problems. The present study explored negative urgency in relation to a common problem among adolescents: difficulty in interpersonal relationships. Since negative emotions precede action among individuals high in negative urgency, we investigated the role of depressive symptoms in this association. A sample of 272 youth (M = 11.75 years, SD = 0.93, 79.78% female) completed self-report measures of negative urgency, depressive symptoms, and interpersonal problems with peers, mothers, and fathers at two time points. Negative urgency cross-sectionally predicted interpersonal problems with peers and mothers, but not fathers. A heightened level of depressive symptoms among negatively urgent youth explained this effect and continued to show significant indirect associations with urgency and peer relationships four months later. Negative urgency appears to represent a global disposition, linked with interpersonal problems across multiple relationships. • Negative urgency is associated with interpersonal problems among youth. • Depressive symptoms partially explain this association. • These associations are present both cross-sectionally and longitudinally. • Negative urgency matters for not only psychopathology, but also daily problems.
