The goal of this study was to examine how individual differences in physiological arousal and reactivity moderated the relation between peer victimization and reactive and proactive aggression. Participants were 58 adolescents (61.2% boys; 54.9% African American) in the age range of 12--15. Participants self-reported peer victimization, reactive…

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…

The purpose of the current investigation was to examine if autonomic nervous system reactivity moderated the association between relational victimization and two established outcomes of peer maltreatment, anxious/depressive symptoms and anxious rejection sensitivity. A total of 119 female (M[subscript age] = 12.47, SD[subscript age] = 1.96)…

Peer victimization is associated with increased risk for mental health problems. These adverse psychological outcomes are linked with altered cognitive and emotional processes and their related neural functioning. In the present study, by using functional magnetic resonance imaging (fMRI), we examined whether peer victimization was associated with…

A growing body of literature indicates that childhood emotion regulation predicts later success with peers, yet little is known about the processes through which this association occurs. The current study examined mechanisms through which emotion regulation was associated with later peer acceptance and peer rejection, controlling for earlier…

Gene-environment studies on adolescents' peer contexts are important for understanding the interplay between biological and social antecedents of adolescent psychopathology. To this end, this study examined the roles of serotonin transporter (5-HTTLPR) and preadolescent and early adolescent peer rejection and acceptance, as well as the interaction…

This study examined the relations between multiple types of peer victimization, affective reactivity to victimization, and academic achievement. Participants (179 fifth-grade boys and girls) completed repeated daily measures of peer victimization and negative affect; a standardized measure of achievement was collected concurrently. The daily…

Perceived popularity is associated with both positive and negative characteristics, and adolescents' stereotypes associated with popularity reflect this paradox. The current study investigated adolescents' stereotypes associated with popularity and gender, as well as their liking for popular peers who engage in prosocial, antisocial, and…

Two kinds of parental behaviors--psychological control and emotional warmth--have been linked with children's shy behaviors. The questions we addressed are whether this applies to adolescent shyness, and whether shyness in itself might also affect perceptions of parental behaviors. The participants were 916 seventh to ninth graders in a…

We examined whether the bystanders' behaviors in bullying situations influence vulnerable students' risk for victimization. The sample consisted of 6,980 primary school children from Grades 3-5, who were nested within 378 classrooms in 77 schools. These students filled out Internet-based questionnaires in their schools' computer labs. The results…

The goal of the current study was to investigate whether peer rejection and peer victimization mediated the relation between children's aggressive behaviors and depressive symptoms. Participants were 533 fourth- and fifth-grade children (289 girls and 244 boys). Data on aggression and peer victimization were collected through teacher and peer…

We evaluated the extent to which aggressive victims show unique developmental pathways that are different from those of passive victims, bullies, and uninvolved children. A total of 1,722 children were followed from 4th grade to 6th grade, and the prevalence and stability of each group were assessed. Aggressive victims became less prevalent and…

This study examined associations between sociometric status and friendship quality using observational and questionnaire data from 139 fourth-grade girls and their friends. Multivariate analyses of covariance (controlling for ethnicity and socioeconomic status) showed that rejected girls and their friends did not differ in their reported…
