Hanging Out With the Right Crowd: Peer Influence on Risk‐Taking Behavior in Adolescence

Peer influence plays a key role in the increase of risk‐taking behavior during adolescence. However, its underlying processes are not fully understood. This study examined the effects of social norms, conveyed through peer advice, on risk‐taking behavior in 15‐ to 17‐year‐old adolescents (N = 76). Participants played a card‐guessing task alone and with online peer advice. Results showed that risk‐taking increased in the presence of peers. The results further showed that adolescents took into account the uncertainty associated with gambles, as well as the social norms conveyed by peers. Our findings suggest that peers are most influential in uncertain situations and demonstrate the value of a social norms approach in examining the processes underlying peer effects.     

Socioeconomic Risk for Adolescent Cognitive Control and Emerging Risk‐Taking Behaviors

This study examined whether cognitive control mediated the association between socioeconomic status (SES; composite of income‐to‐needs ratio and parent education) and changes in risk‐taking behaviors. The sample included 167 dyads of adolescents (53% male; M_age = 14.07 years at Time 1) and their parents, assessed annually across 4 years. Parents reported socioeconomic variables at Time 1. Adolescents reported risk‐taking behaviors at Times 1 and 4, and completed a functional magnetic resonance imaging cognitive control task at Times 2 and 3. Lower SES was associated with lower behavioral (but not neural) cognitive control, which was associated with increases in risk‐taking behaviors. The findings suggest that elevated socioeconomic risk may compromise cognitive control which can cascade into maladaptive behaviors in adolescence.     

Off‐Time Pubertal Timing Predicts Physiological Reactivity to Postpuberty Interpersonal Stress

We investigated associations between retrospectively assessed timing of pubertal development, interpersonal interactions, and hypothalamic–pituitary–adrenal axis reactivity to an interpersonal stress task in 110 young adult women. Participants provided salivary cortisol samples at points prior and subsequent to a video‐taped conflict discussion with their romantic partner. Participants also provided subjective global ratings of their discussion on dimensions of conflict and support. For earlier developing girls, higher levels of interpersonal conflict were associated with greater physiological stress in anticipation of the discussion task and less physiological recovery following the discussion. In contrast, for later developing girls, low levels of conflict were associated with greater anticipatory stress and less physiological recovery. These findings have implications for understanding the influence of off‐time pubertal development on the lifetime development of young women.     

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.     

Sexual Risk‐Taking Among Recently Emancipated Female Foster Youth: Sexual Trauma and Failed Family Reunification Experiences

Foster youth evidence shows elevated rates of risk behaviors, including sexual risk‐taking (e.g., unprotected sex). Some studies have identified child maltreatment, particularly sexual abuse, as a risk for later sexual risk‐taking, but none have examined how child welfare placement experiences relate to youth's sexual risk‐taking. This study investigated relations among child maltreatment, child welfare placements, and sexual risk‐taking among 114 recently emancipated female foster youth. Sexual abuse and failed reunifications with parents were associated with greater sexual risk‐taking. Moreover, dissociative symptoms exacerbated the relation between sexual abuse and sexual risk‐taking. These findings highlight the need for greater consideration of risks associated with emancipated youth's sexual risk‐taking and for more research to understand how youth experience unsuccessful family reunifications.     

Susceptibility to Peer Influence,Self‐Control,and Delinquency

The significance of peers during adolescence is well established in the social science literature. However, relatively few studies have devoted attention to susceptibility to peer influence with regard to both its causes and consequences. The current study aims to add to this literature in two ways. First, it investigates the role of self‐control in the etiology of susceptibility to peer influence. Second, it examines the independent and interactive effects of these two constructs on self‐reported delinquency. Results indicate that individuals who are higher in self‐control are less likely to be susceptible to peer influence, that susceptibility is a stronger predictor of delinquency than self‐control, and that the influence of susceptibility on delinquency is moderated by one's level of self‐control. In particular, the effect of susceptibility to peer influence on delinquency is stronger for individuals with higher levels of self‐control. The implications of the findings for theory and future research are discussed.     

Pubertal Timing as a Potential Mediator of Adoption Effects on Problem Behaviors

Adopted children show more problem behaviors than nonadopted children. Given that internationally adopted individuals show earlier puberty than nonadopted individuals, and early puberty is associated with problem behaviors in nonadopted youth, we analyzed data from adopted domestic adoptees to determine whether problem behaviors could be explained by differences in pubertal timing. Relative to nonadopted controls (n = 153), domestically adopted girls (n = 121) had earlier menarche, earlier sexual initiation, and more conduct disorder symptoms. Age at menarche partially mediated the relation of adoptive status to sexual initiation, but not to conduct disorder symptoms. Extending findings from international adoptees, results show that domestic adoption is also linked to earlier puberty, and suggest early puberty as one mechanism linking adoption to problematic outcomes.     

Family,Peer, and Pubertal Determinants of Dating Involvement Among Adolescents

This study examines the influence of family, peer, and biological contributors to dating involvement among early adolescents (11–14 years of age; n = 244). Further, we assess how parental monitoring may be modified by pubertal maturation and older sibling risky behavior. Data on delinquent peer affiliation, pubertal maturation, parental monitoring, older sibling risky behavior, and dating involvement were gathered through observations and surveys from adolescents, mothers, older siblings, and teachers. Results indicate that lower levels of parental monitoring and higher levels of older sibling risky behavior were related to adolescents' dating involvement through delinquent peer affiliation. Pubertal maturation was directly related to dating involvement for early daters. Findings emphasize the value of examining social and biological factors, in concert, over time.     

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.     

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 Consequences of Objective and Subjective Status Inconsistency*

The phenomenon of status inconsisitency, while having rich potential as an explanatory variable, has been beset with methodological problems and conflicting findings. Nelson has argued that the use of objective and subjective components of status inconsistency will allow for a more accurate test of its usefulness (1973). The present study, using a sample of 1971 male college graduates interviewed in 1974, analyzed the attitudinal and behavioral consequences of one type of status inconsistency (under-rewarded) incorporating objective and subjective techniques. The tentative conclusions were: (1) the use of subjective measures of inconsistency validates this phenomenon as an explanatory variable; (2) the use of subjective measures minimizes the methodological criticisms of the objective approach; and (3) both objective and subjective measures of status inconsistency should be incorporated in future research.

The Moderating Effects of Pubertal Timing on the Longitudinal Associations Between Parent–Child Relationship Quality and Adolescent Substance Use

This prospective, longitudinal study investigated the moderating role of pubertal timing on reciprocal links between adolescent appraisals of parent–child relationship quality and girls' (N=1,335) and boys' (N=1,203) cigarette and alcohol use across a 12‐month period. Reciprocal effects were found between parent–child relations and on‐time maturing boys and girls' cigarette and alcohol use, after estimating stability in these constructs across time. Parent–child relationship quality was associated with increased alcohol use 12 months later for early maturing girls. Cigarette and alcohol use were associated with increased problems in the parent–child relationship for late maturing girls. No effects were observed for early and late maturing boys in the pathways between parent–child relationship quality and substance use. Pubertal timing moderated the pathway linking parent–child relationship quality with cigarette use 1 year later such that the association was stronger for late maturing girls compared with early and on‐time maturing girls. The findings indicate interplay between the psychosocial aspects of maturation, family relationships, and adolescent substance use and highlight possible gender‐specific influences.     

Peer Crowd Affiliation and Internalizing Distress in Childhood and Adolescence: A Longitudinal Follow‐Back Study

Concurrent and longitudinal associations between peer crowd affiliation and internalized distress were examined in a sample of 246 youth (148 girls, 98 boys). Children completed measures of depression, social anxiety, loneliness, and self‐esteem when they were in grades 4 to 6 (Time 1), and again 6 years later during adolescence (grades 10 – 12; Time 2). At Time 2, adolescents also reported their self‐concept and their identification with reputation‐based peer crowds, including Populars, Jocks, Brains, Burnouts, Non‐Conformists, and None/Average crowds. Results indicated that adolescents' report of peer crowd affiliation was concurrently associated with self‐concept and levels of internalizing distress. Follow‐back analyses of internalizing trajectories revealed that Populars/Jocks had experienced significant declines in internalizing distress across development, whereas Brains exhibited some increases in internalizing distress between childhood and adolescence.     

Development and Lability in the Parent–Child Relationship During Adolescence: Associations With Pubertal Timing and Tempo

Adolescents' and parents' reactions to pubertal development are hypothesized to contribute to changes in family dynamics. Using 7‐year longitudinal data from the NICHD‐SECCYD (488 boys, 475 girls), we examined relations between pubertal development (timing, tempo) and trajectories (developmental change and year‐to‐year lability) of parent–child conflict and closeness from age 8.5 to 15.5 years. Changes were mostly characterized by year‐to‐year fluctuations—lability. Parent–child conflict increased and closeness decreased some with age. Pubertal timing and tempo were more consistently associated with lability in parent–child relationships than with long‐term trends, although faster tempo was associated with steeper decreases in parent–child closeness. Findings provide a platform for examining how puberty contributes to both long‐term and transient changes in adolescents' relationships and adjustment.     

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.     

Aversive Peer Experiences on Social Networking Sites: Development of the Social Networking‐Peer Experiences Questionnaire (SN‐PEQ)

Cyber victimization is an important research area, yet little is known about aversive peer experiences on social networking sites (SNSs), which are used extensively by youth and host complex social exchanges. Across samples of adolescents (n = 216) and young adults (n = 214), we developed the Social Networking‐Peer Experiences Questionnaire (SN‐PEQ) and examined its psychometric properties, distinctiveness from traditional peer victimization measures, and associations with internalized distress. The SN‐PEQ demonstrated strong factorial invariance and a single‐factor structure that was distinct from other forms of peer victimization. Negative SNS experiences were associated with youths' symptoms of social anxiety and depression, even when controlling for traditional peer victimization. Findings highlight the importance of examining the effects of aversive peer experiences that occur via social media.     

Mexican‐Origin Mothers' and Fathers' Involvement in Adolescents' Peer Relationships: A Pattern‐Analytic Approach

Using latent profile analysis, the authors examined patterns of mother – father involvement in adolescents' peer relationships along three dimensions—support, guidance, and restrictions—in 240 Mexican‐origin families. Three profiles were identified: (a) High Mother Involvement (mothers higher than fathers on all three dimensions), (b) High Support/Congruent (mothers and fathers reported the highest levels of peer support and similar levels of guidance and restrictions), and (c) Differentiated (more guidance and restrictions by fathers than by mothers, similar levels of parent support). These profiles were linked to mothers' and fathers' familism values, traditional patriarchal gender role attitudes, and socioeconomic status and to adolescents' friendship intimacy and risky behaviors measured longitudinally from early to late adolescence. Adolescent gender moderated the linkages between parents' involvement in adolescents' peer relationships and youth adjustment.
