--- - |2 In this study, we aimed to characterize developmental patterns of poly‐victimization in a normative sample of adolescents by applying longitudinal latent class analysis. Using the four most recent waves of data from the Zurich Project on the Social Development of Children and Youths (z‐proso), we identified three classes, or separate groups, of youths with distinct patterns of victimization from age 11 to 17. The largest class represented young people who were least likely to be victimized in any way and at any time. The two smaller groups represented different types of poly‐victimization—a non‐parental and a long‐term parental victimization group. Adolescents in the two groups differed both in the number as well as type of victimization that they experienced at different times. Moreover, class membership also had implications for different mental health outcomes. - Journal of Research on Adolescence, EarlyView.
