Does recent physical and sexual victimization affect further substance use for adult drug-involved offenders?

This study examined whether physical and sexual victimization experiences were related to further substance use for a sample of drug-involved adult offenders and whether this increase could be attributed to depression experienced after the victimization occurred. A total of 674 men and 284 women from the longitudinal Multisite Adult Drug Court Evaluation (MADCE) were included in analyses. The study included 23 drug court and 6 comparison sites. Study participants completed three interviews: at baseline enrollment and then at 6 and 18 months after baseline. Multilevel path modeling showed that physical and sexual victimization experiences during the year before the baseline interview were associated with further substance use at 18 months and that this relationship was mediated by depression. All relationships held for both men and women, and beyond the contribution of several control variables, including drug court program participation. Public health and criminal justice personnel working with substance-using offenders should screen individuals for victimization-related trauma and, if identified, provide assistance to evaluate and improve such individuals' mental health and, subsequently, decrease their likelihood of using substances.
