Purpose:We examined how heterogeneity in the patterns of adolescent experiences of different types and severity of peer victimization is associated with concurrent and longitudinal mental health, substance use, and physical health.Method: Data come from a randomly recruited communitybased sample of youth (T1 ages 12-18; N = 662; 52% female) followed biennially across 10 years (T6 ages 22-29; n = 478; 55% female).
Results: Using latent class analysis, we identified four classes of adolescent peer victimization: Low victimization (63%), Physical victimization only (15%), Relational victimization only (17%), and Poly-victimization (6%). Youth in the Poly-victimization class reported the most detrimental health consequences in adolescence (e.g., internalizing and externalizing symptoms, illicit drug use, physical symptoms, poor physical self-concept, physical activity) and in young adulthood (e.g., depressive symptoms, sleep problems). Youth in the Relational and Physical victimization classes also reported health problems, some of which persisted into young adulthood. Youth in the Low victimization class reported the fewest health concerns.Conclusions: Findings add to our understanding of how different types of adolescent victimization are related to the hypothalamic-pituitary-adrenal axis (HPA; i.e., the body's stress response system), as well as blunted cortisol release also found in children and adolescents who experience other forms of stress or trauma (see Vaillancourt et al., 2013 for reviews). However, it is not known whether or how adolescent victimization experiences set the stage for continued health problems in young adulthood. The health effects (concurrent and across time) of different experiences of victimization (i.e., based on type and severity) are also not known. In this study, we add to the understanding of how different patterns of peer victimization affect mental health, substance use, and physical health in adolescence (ages 12-18) and 10 years later in young adulthood (ages 22-29).
