Polyvictimization, Related Symptoms, and Familial and Neighborhood Contexts as Longitudinal Mediators of Racial/Ethnic Disparities in Violence Exposure Across Adolescence.

African American and Hispanic adolescent experience more violence exposure relative to White youth. The present study examined the mediating role of posttraumatic stress symptoms (PTSS), delinquency, earlier victimization, and familial and neighborhood factors in disparities in future victimization. The study utilized data from the National Survey of Adolescents-Replication (N = 3,312), which consists of three waves of data collected approximately 1 year apart. A series of path models, tested polyvictimization, PTSS, delinquency, familial socioeconomic factors, and neighborhood safety as mediators of disparities in new polyvictimization. All cross-lagged and autoregressive paths positively predicted past-year polyvictimization and mediated longitudinal disparities. Familial socioeconomic variables and neighborhood safety mediated initial violence exposure disparities. Overall, results indicate that prior violence exposure, related mental health symptoms, and familial and neighborhood factors account for significant portions of disparities in new violence exposure across adolescence.
