Abstract
OBJECTIVE: Exposure to violent victimization is associated with higher rates of mental health and substance use disorders (SUD). Some youth who experience multiple victimizations and associated characteristics (i.e. poly-victims) are at heightened risk for long term problems. Thus, we conducted the first study to examine how heterogeneity in experiences of victimization vary in terms of latency to illicit drug use following treatment completion. We also examined if victimization profiles vary across gender and if comorbid conditions (e.g., posttraumatic stress disorder and major depressive disorder) differentially predict latentcy to illicit drug use across groups. METHODS: Adolescents and young adults (N = 5956; Mage = 17.5 years; 64.0% male) with SUDs in treatment for illicit drug use completed a battery of measures at baseline. At 3-, 6- and 12-month follow-ups, they reported on the number of days before they used any illicit drug following their last assessment. RESULTS: Continuous time survival mixture modeling revealed that, as hypothesized, females who experienced high rates of all victimization and related characteristics had a higher hazard for latency to first illicit drug use as compared to females in the low victimization group. This was not the case for males; rather, those who experienced high rates of sexual abuse were quickest to return to illicit drug use. Finally, comorbid conditions led to a higher hazard rate, but only for certain profiles across females. DISCUSSION: Findings emphasize the necessity for professionals to more fully integrate poly-victimization research and theory into their clinical practices and research.
