The current study of 668 Israeli male and female students examines the prevalence of gendered risk factors for sexual assault (SA) on dates, posttraumatic stress disorder (PTSD) as a detrimental effect of SA, and self-efficacy as resiliency to refuse unwanted sex following SA. Two different sets of risk factors that increased the likelihood of SA on dates emerged from the hierarchical regression. Sexual experience, use of drugs, and private location increased the risk of being SA victims among males, whereas sexual experience, perceived provocative behavior, and alcohol use increased the risk among females. In addition, PTSD and self-efficacy to refuse unwanted sex following SA on dates were predicted by the extent of coercive sexual victimization. PTSD was also predicted by subjective perception of sexual behavior and rape myths, whereas efficacy was predicted by private location. The findings contribute to the literature by showing the contribution of various risk factors to experiencing SA, and by showing SA effect on PTSD and self-efficacy.
