This investigation tested a program to reduce women's risk for sexual revictimization. Participants were 66 women with histories of sexual victimization as adolescents or adults who were randomly assigned to a preventive intervention group or a no-treatment control group. They completed initial measures assessing history of sexual assault, self-efficacy, and psychological functioning, returning approximately 2 months later for follow-up assessment using the same measures. Results suggest that the prevention program may be effective in reducing the incidence of sexual assault revictimization in this population. In addition, participants in the intervention group displayed significant improvement in psychological adjustment and self-reported self-efficacy.
