The objective of the proposed study is to develop an innovative, friend-based motivational interview (FMI) that encourages and prepares friends to reduce sexual assault (SA) risk. Delivered to pairs of friends (dyads), the FMI will be designed to foster collaborative efforts to increase readiness for, and decrease barriers to helping behavior, and to teach and plan together for assault prevention skills. As the role of alcohol has been under-addressed in SA prevention efforts, the FMI also will explicitly attend to how intoxication may serve as a barrier to friend intervention, and strategies for overcoming this barrier. The completion of this project's aims will yield a novel intervention that capitalizes on the natural resource of women's friendships to decrease risk for sexual assault - a pervasive public health problem affecting a substantial portion of young adult women in the U.S.~Twenty-four friend dyads will participate in the friend-based motivational interview (FMI) along with 24 wait-list control dyads (total of 48 dyads). The study will compare groups on outcomes at post-intervention and at bi-weekly 3 month follow-ups, and also examine within participant change. The study will focus on whether effects are in the expected direction and whether the strength of effect sizes are of practical magnitude. It is expected that participants receiving the FMI will demonstrate significant increases in readiness, and engagement in friend assault prevention behavioral skills (FAPBs), and demonstrate decreases in perceived barriers, at post-intervention and over the 3-month follow-up. Follow-up data will be utilized to provide a rich description of the role of alcohol in implementing FAPBs, and whether the FMI reduces the impact of alcohol use. In exploratory analyses, it will be examined whether the intervention may be associated with decreased assault risk, as well as decreased drinking.
The current project will provide testing of a friend-based motivational interview (FMI) designed to reduce sexual assault risk. The study will address if the intervention minimizes the impact of alcohol on helping behavior, test whether drinking reduces intervention efficacy, and examine potential iatrogenic effects of the intervention.
