Sexual violence is associated with posttraumatic stress disorder (PTSD), but relatively less research has explored whether it is associated with hazardous drinking. PTSD symptoms may indirectly influence the association between sexual violence and hazardous alcohol use. This association may be moderated by gender. The aim of the current study was to cross-sectionally test whether sexual violence is indirectly associated with hazardous drinking through PTSD symptoms and explore whether gender moderates this association. Hypotheses were tested among 631 adults (Mage = 38, 56% men, 78.6% White) with probable PTSD and hazardous drinking who completed online self-report surveys. Results indicated sexual violence, compared with other trauma types, was associated with more severe hazardous drinking. There was a significant indirect effect of PTSD symptoms in this association. There was no evidence of a moderating effect of gender. PTSD symptoms may drive hazardous drinking among sexual violence survivors. Results also underscore associations between sexual violence and alcohol use, regardless of gender. Future work should continue to investigate these associations prospectively.
