Posttraumatic stress disorder (PTSD) is highly prevalent among individuals who experience intimate partner violence (IPV) and is associated with aggression in intimate relationships. The present study examined whether alcohol dependence (AD) attenuates the relation between PTSD and IPV‐victimized women's use of physical, psychological, and sexual aggression. Participants were recruited from the community and included 147 women who engaged in substance use and experienced IPV (80.3% Black; M age = 38.24 years, SD = 10.62; M income = $14,323, SD = $12,832). Women with (vs. without) AD reported using significantly more physical and psychological aggression (η p 2 = .12 and .03, respectively). The probable PTSD × AD interaction emerged as a significant correlate of physical and sexual aggression (η p 2 = .03). Post hoc analyses revealed higher levels of physical aggression among women with probable PTSD and AD and no‐PTSD and AD compared to women with probable PTSD and no‐AD (Cohen's d s = 1.09 and 0.63, respectively) and women without PTSD and no‐AD (Cohen's d s = 0.92 and 0.60, respectively). Further, women with PTSD and AD reported higher levels of sexual aggression than women without PTSD and AD (Cohen's d = 0.80). Findings suggest the utility of identifying and treating PTSD‐AD among IPV‐victimized women.
