Adolescents' negative expectations of their peers were examined as predictors of their future selection of hostile partners, in a community sample of 184 adolescents followed from ages 13 to 24. Utilizing observational data, close friend- and self-reports, adolescents with more negative expectations at age 13 were found to be more likely to form relationships with observably hostile romantic partners and friends with hostile attitudes by age 18 even after accounting for baseline levels of friend hostile attitudes at age 13 and adolescents' own hostile behavior and attitudes. Furthermore, the presence of friends with hostile attitudes at age 18 in turn predicted higher levels of adult friend hostile attitudes at age 24. Results suggest the presence of a considerable degree of continuity from negative expectations to hostile partnerships from adolescence well into adulthood.

The potential importance of depending on others during adolescence to establish independence in young adulthood was examined across adolescence to emerging adulthood. Participants included 184 teens (46% male; 42% non-White), their mothers, best friends, and romantic partners, assessed at ages 13-14, 18, 21-22, and 25. Path analyses showed that associations were both partner and age specific: markers of independence were predicted by participants' efforts to seek support from mothers at age 13, best friends at 18, and romantic partners at 21. More important, analyses controlled for support seeking from these partners at other ages, as well as for other potentially confounding variables including attachment security, scholastic/job competence, and physical attractiveness over time. Moreover, analyses suggested the transfer of support seeking behavior from mothers to best friends to romantic partners over time based on support given by the previous partner at an earlier age.

Adolescents' negative social expectations of their peers were examined as long-term predictors of problematic self-reported social functioning. Early adolescent negative expectations were hypothesized to predict risk-averse functioning in late adolescence that would ultimately contribute to confirmation of those expectations. Utilizing observational data and friend- and self-reports from a community sample of 184 adolescents followed from ages 13 to 25, adolescents with more negative expectations were found to have become increasingly submissive with friends over time and were rated as less romantically appealing by late adolescence (after controlling for baseline levels of these variables, baseline friend-rated social competence and self-reported depressive symptoms). In turn, submissiveness and romantic appeal predicted problematic self-reported social functioning well into adulthood and mediated the relationship between adolescent negative expectations and problematic self-reported adult social functioning. These findings support the possibility of a self-fulfilling social process unfolding from early adolescence to adulthood.

Maternal and paternal psychological control, peer attitudes, and the interaction of psychological control and peer attitudes at age 13 were examined as predictors of risky sexual behavior before age 16 in a community sample of 181 youth followed from age 13 to 16. Maternal psychological control moderated the link between peer attitudes and sexual behavior. Peer acceptance of early sex predicted greater risky sexual behaviors, but only for teens whose mothers engaged in high levels of psychological control. Paternal psychological control demonstrated the same moderating effect for girls; for boys, however, high levels of paternal control predicted risky sex regardless of peer attitudes. Results are consistent with the theory that peer influences do not replace parental influences with regard to adolescent sexual behavior; rather, parental practices continue to serve an important role either directly forecasting sexual behavior or moderating the link between peer attitudes and sexual behavior.

Peer victimization has been implicated as a traumatic stressor that compromises children's long-term mental health, yet a dearth of prospective research documents lasting effects of early victimization. This study examined whether early (2nd grade) and increasing (2nd-5th grade) victimization predicted 5th grade depressive symptoms and aggressive behavior. Children (238 girls, 195 boys) reported on victimization and depressive symptoms; teachers reported on victimization and aggressive behavior. Latent growth curve analysis revealed that early and increasing victimization made unique contributions to depressive symptoms and aggressive behavior. Relational aggression was particularly likely to follow victimization in girls. This study reveals that victimization contributes to mental health over an extended period and elucidates the role of early versus increasing victimization, supporting the need for programs to prevent the pernicious mental health consequences of victimization.

Although research on the reasons for engaging in nonsuicidal sell-injury (NSSI) has increased dramatically in the last few years, there are still many aspects of this pernicious behavior that are not well understood. The purpose of this study was to address these gaps in the literature, with a particular focus on investigating whether NSSI (a) regulates affective valence in addition to affective arousal and (b) serves a cognitive regulation function in addition to an affect regulation function. To elucidate these issues, the present study utilized a sample of 112 participants (33 controls, 39 no pain controls, 16 NSSI individuals, and 24 controls matching the affect dysregulation levels of the NSSI group), employed psychophysiological measures of affective valence (startle-alone reactivity) and quality of information processing (prepulse inhibition), and used experimental methods involving an NSSI-proxy to model the NSSI process. Results largely were consistent with predictions, supporting the hypotheses that NSSI serves to regulate cognitive processing and affective valence. On this latter point, however, the control groups also showed a decrease in negative affective valence after the NSSI-proxy. This unexpected finding is consistent with the hypothesis that opponent processes may contribute to the development of self-injurious behaviors (Joiner, 2005). Overall, the present study represents an important extension of previous laboratory NSSI studies and provides a fertile foundation for future studies aimed at understanding why people engage in NSSI.

This study examined adolescents' ability to utilize emotional repair-to actively change negative moods to more positive moods-as a predictor of the quality of their developing peer and romantic relationships over time. Utilizing observational data and partners' reports, adolescents ( N = 184), their close peers, and their romantic partners were followed from ages 15-19. Adolescents with initially stronger emotional repair abilities were rated as increasingly socially competent over time, and both displayed and experienced increasingly positive interactive behaviors with close peers over time. These adolescents' romantic partners also reported more positive relationships, with enhanced communication, and fewer critical, blaming, or hostile interactions. Implications for the role of emotional repair abilities in the development of successful relationships during adolescence are discussed. [ABSTRACT FROM AUTHOR]
