Examined the relations among overt and relational victimization, social anxiety, loneliness, and prosocial behaviors from peers in ninth- and tenth-graders. Found that boys reported higher overt victimization rates and fewer peer prosocial behaviors compared to girls. Found support for the hypothesis that overt and relational victimization were positively associated with fear of negative evaluation, physiological symptoms, social avoidance, and loneliness. Peer prosocial behaviors moderated effects of victimization on loneliness. (Author/KB)
