To understand the predictors of continuity and discontinuity of overt and relational victimization over an extended period of time, this study examined the independent and unique contributions of predictors that are associated with individual characteristics (social behavior) and a contextual factor (peer adversity), from 2nd to 8th grade, spanning the transition to middle school. In Chapter 1, the overall trajectories of victimization were found to decline for both types of victimization for both girls and boys. In Chapter 2, the independent contribution of each predictor to the intercepts and trajectories of victimization was examined. The analyses demonstrated that both individual and peer context factors contribute to 2nd grade victimization and the trajectories of victimization. Interestingly, some of these effects were stronger in boys during elementary school and in girls after the transition to middle school. In Chapter 3, unique contributions of predictors were investigated by examining the effects of predictors simultaneously. Overall, the results suggested that peer adversity did not predict 2nd grade victimization or the trajectories of victimization above and beyond individual characteristics. Results are discussed in regards to prevention of prolonged victimization, with attention to sex differences and youth who have multiple risk factors.","abstract_html":"Peer victimization can be a chronic stressor for some youth but not all youth.
