Background: This study examined whether a brief video intervention (Prevention of Post-Rape Stress [PPRS]) delivered in the emergency department to recent sexual assault (SA) victims reduced alcohol and marijuana use at 3 points over the course of a 6-month follow-up compared to treatment as usual (TAU) and an active control condition (Pleasant Imagery and Relaxation Instruction [PIRI]). Prior assault history, minority status, and pre-SA substance use also were examined as moderators of intervention efficacy. Methods: Women aged 15 and older (N = 154) who participated in a post-SA medical forensic examination were randomly assigned to watch the PPRS video (n = 54) or the PIRI video (n = 48) or receive TAU (n = 52) and completed at least 1 follow-up assessment targeted at 1.5 (T1), 3 (T2), or 6 (T3) months following the examination. Results: Regression analyses revealed that, relative to TAU, PPRS was associated with less frequent alcohol use at 6 months post-SA among women reporting pre-SA binge drinking and minority women. Relative to TAU, PPRS also was associated with fewer days of marijuana use at T1 among those who did not report pre-SA marijuana use and prior SA. Findings for pre-SA marijuana use were maintained at T3; however, findings for prior SA shifted such that PPRS was associated with fewer days of marijuana use at T3 for women with a prior SA. Conclusions: PPRS may be effective at reducing substance use for some recent SA victims, including those with a prior SA history, a prior substance use history, and minority women.
