The current study examined peer victimization trajectories for 1528 children from third to fifth grade and the association of those trajectories to children’s positive and negative affect. On average, victimization was low to moderate and remained stable (self-report) or increased (peer-reports). In addition, five distinct trajectories were identified based on self-report: Low, Moderate, Increasing, Decreasing, and Chronic. Peer-reported victimization did not reveal distinct trajectories. Although the level of victimization was related to concurrent negative affect (self- and peer-reported victimization) and to positive affect (self-report victimization only), relations between change in victimization and change in affect were less consistent. Also, a chronic victimization trajectory was associated with greatest affective distress and a decreasing trajectory was associated with partial, but not full, recovery in terms of affect. Results largely support a chronic model of victimization’s effects in which victimization has compounding and enduring effects on adjustment. Intervention implications include the importance of including selective interventions for highly victimized youth with universal anti-bullying programs, assessing both past and current victimization, and including indicators of adjustment when evaluating anti-bullying interventions.

Research indicates social anxiety is associated with lower friendship quality, but little is known about the underlying mechanisms. This 2-month longitudinal study examined social withdrawal as a mediator of the social anxiety-friendship quality link in a sample of 214 adolescents (M age = 13.1 years, SD = .73) that included an oversampling of adolescents recently relocated to the community (n = 155). Findings provided preliminary support for the hypothesized models, in which social anxiety is associated with social withdrawal, which in turn is related to lower companionship and intimacy in adolescents' friendships. Analyses testing whether relocation to a new community intensifies these associations indicated additive, but not multiplicative, effects of social anxiety and relocation on friendship companionship and intimacy. Implications include the importance of increasing socially anxious youths' social engagement and skills with friends as well as with less familiar peers.

This study evaluated the Gentle Warrior Program, a traditional martial arts-based intervention to reduce aggression in children, as it was implemented in three elementary schools. The sample consisted of 254 children in grades 3, 4, and 5 who participated in the Gentle Warrior Program as part of a larger school violence intervention. Results indicated that boys who participated in more Gentle Warrior sessions reported a lower frequency of aggression and greater frequency of helpful bystanding (i.e., helpful behavior toward victims of bullying) over time, relative to boys with less frequent participation. The effect of participation on aggression was partially mediated by empathy. The effect of participation on helpful bystanding was fully mediated by changes in student empathy. No significant results were found for girls. Results of the study provide preliminary support for the use of martial arts-based interventions to address bullying in schools for boys, by teaching empathy, self-control, and peaceful strategies to resolve conflicts.
