Findings highlight the deleterious effects of peer victimization, especially relational victimization, and suggest avenues for clinical intervention for adolescents experiencing such victimization. This study confirmed the concurrent association between social anxiety and peer victimization and revealed that social anxiety both predicts and is predicted by peer victimization over time. Relational victimization has a stronger association with social anxiety than reputational victimization, and may more adversely affect girls than boys. Social anxiety predicted increases in relational victimization over time for both boys and girls, thus supporting a bi-directional relationship between peer victimization and social anxiety. Data were collected from 228 adolescents in grades 10-12 from a large public high school in southern Florida. Participants completed the Social Anxiety Scale for Adolescents and the Revised Peer Experiences Questionnaire, at time 1 and 2 months later, at time 2. The self-reporting measures were completed in school during group testing sessions. Tables and references
