Mediators of the Relationship Between Sexual Assault and Sexual Behaviors in College Women.

Some research shows that sexual assault victimization is associated with increased engagement in risky sexual behavior (e.g., intercourse without use of a condom or contraceptives), whereas other research indicates sexual assault victimization is related to sexual aversion. The purpose of the current study was to examine whether posttraumatic stress symptoms, alcohol use, and sexual assertiveness mediated the relationship between adolescent/emerging adulthood sexual assault (ASA) and risky sexual behavior, and whether posttraumatic stress symptoms mediated the relationship between ASA and sexual aversion, among college women. A sample of 462 women from a Midwestern university completed online questionnaires assessing ASA, child sexual abuse (CSA), posttraumatic stress symptoms (i.e., intrusion, avoidance, hyperarousal, and dissociation), alcohol use, sexual assertiveness, risky sexual behavior, and sexual aversion. CSA was considered as a covariate in the mediation models. Results of mediation analyses showed that the relationship between ASA and risky sexual behavior with a new partner was partially mediated by greater alcohol use and lower sexual assertiveness and that the relationship between ASA and risky sexual behavior with a regular partner was partially mediated by greater alcohol use. Results of a model examining mediators of ASA and sexual aversion detected no significant mediators. Results suggest that college women with a history of ASA would benefit from psychoeducation on the effect of alcohol on sexual decision-making, as well as from sexual assertiveness skills training, to reduce potential risks associated with risky sexual behaviors, particularly with lesser known partners, including sexually transmitted infections and sexual revictimization.
