The current investigation uses longitudinal data to begin to understand the correlates of gender integration and youth emotional adjustment. Participants were 207 adolescents (mean age = 11.11 years, 53% female). The results demonstrated that, when compared to only having gender-segregated peer affiliates, gender-integrated peer affiliates, as…

Previous research has shown that adolescent peer groups play a role in maintaining and exacerbating demographic differences in achievement. However, there is still limited knowledge about the malleable factors that contribute to these achievement disparities. This short-term longitudinal study examined one such malleable factor--namely, perceived…

As a test of the poor-get-poorer hypothesis, which shows that socially anxious teens are less likely to communicate online and in turn feel less closeness to friends, this study explored whether peer victimization is similarly related to social media involvement. High-school participants (n = 307, M[subscript age] = 15.91) reported about their…

This study investigated how two aspects of the classroom environment (teachers' emphasis on mastery goals and descriptive norms (i.e., the average student disruptive, prosocial, and achievement-related behavior in a classroom), moderated the relationship between student behaviors and coolness. The sample included 976 students nested in 54 fifth-…

Numerous studies consider competition and jealousy within an evolutionary framework, yet less is known about the relation between aggression vis-à-vis hypercompetitiveness (i.e., competing to win) and jealousy. We investigated the longitudinal relations between hypercompetitiveness, jealousy, and aggression and the moderating role of gender in a…

Popularity and likability--two measures of adolescent peer status--have been examined frequently within Western cultures but relatively rarely within Eastern cultures. This study offered a cross-cultural comparison of adolescent peer status to examine whether these constructs and their correlates vary between the United States and China. The study…

Despite ample research on the role of parental autonomy support in adolescents' adjustment, the affective processes underlying parental autonomy support remain relatively unclear. As an initial step to fill this gap, the current research examined whether the association between parental autonomy support and adolescents' school adjustment was in…

In this study, the effects of peer acceptance and rejection on global self-esteem and emotional school engagement in adolescents were investigated. Moreover, in line with the differential susceptibility hypothesis, we examined the potential moderating effect of a polymorphism in the serotonin receptor gene (i.e., 5-HTTLPR). The sample consisted of…

This study explored the extent to which loneliness of Indonesian and Chinese adolescents was predicted by their intimacy and conflict with friends and parents. The total sample included 1,833 thirteen- and fifteen-year-old adolescents recruited from urban schools. Boys reported more loneliness than girls, and Chinese boys reported more loneliness…

This study examined the association between ethnicity-related context variables and the prosocial behavior of early adolescents in ethnically/racially diverse schools. Specifically, youths' perceptions of greater representation of same-ethnic peers at school, school support for ethnic diversity, and engagement in and valuing cross-ethnic contact…

The present study investigated the longitudinal association between the development of bullying (traditional bullying and cyberbullying) and the development of moral deficiencies (moral disengagement, low moral responsibility, and weak feelings of remorse) during adolescence. A total of 960 Swiss adolescents completed an electronic questionnaire…

Dynamic features of peer network experiences (membership fluidity and network interconnectedness) were examined for their role in African American and White early adolescents' sense of belonging in mathematics classrooms. Because these dynamic features are naturally present in adolescents' peer group affiliations, attention to them provides a more…
