Developmental trajectories of adolescent victimization: Predictors and outcomes

Chronic victimization negatively affects mental health, making it crucial to understand the key predictive social health (e.g., loneliness, isolation) factors. Evidence suggests that the effects of victimization are worse over the transition from primary to secondary school. Longitudinal data from 1810 students transitioning were used to identify victimization trajectory groups, classified as low increasing, low stable, medium stable, and not bullied. Adolescents with poorer social health were more likely to be in the increasing and stable victimized group than in the not bullied group. Students in the low increasing victimized group had poorer mental health outcomes than those in the stable and not bullied groups. The results of this study have important implications for the type and timing of school-based interventions aimed at reducing victimization and the harms caused by long-term exposure.
