Shorey RC, et al. - In this present study, adolescents (N = 1,042) were enrolled from high schools in Southeast Texas in 2010 and followed annually for six years in order to ascertain whether dating violence victimization (psychological, physical, and sexual) and substance use (alcohol and marijuana) prognosticated sexual behaviors that raise the risk for poor outcomes from ages 15–19. Multilevel modeling exhibited that, when investigating predictors concurrently, for males, marijuana use and psychological victimization prognosticated sexual behaviors over time. For females, marijuana use, and physical and psychological victimization all prognosticated sexual behaviors over time, with marijuana with the most robust impact, especially among females who also used alcohol. Thus, prevention forces for adolescent sexual behaviors that raise the risk for poor outcomes should include a focus on decreasing substance use, especially marijuana, and the impacts of dating violence victimization.
