Summary

The goal of this experimental study is to examine the complex and multifaceted influence of peers on alcohol-involved sexual violence perpetration (ASVP) in U.S. Marine Corps (USMC) men. The specific aims are:

Aim 1: Use ecological momentary assessment (EMA) to examine event-level effects of one's own alcohol use, peer alcohol use, and injunctive norms on ASVP intentions among dyads of Marine men who drink together (n=160 dyads; 320 total participants).

Aim 2: Examine the individual and peer effects on ASVP behavior in an experimental paradigm with a gender x confederate (potential victim) intoxication status design. In-the-moment dyad-peer verbalized encouragement for ASVP ("go cues") will be assessed by qualitatively coding verbalizations during the interaction.

Aim 3: Examine modifiable risk factors on ASVP intentions in vivo (Aim 1; EMA) and ASVP behavior in vitro (Aim 2; experiment) settings.

Participants will complete: 1) an individual orientation session with informed consent, baseline assessment, and EMA demo; 2) 14 days of EMA completed individually; and 3) a dyadic session to complete an experimental paradigm via videoconferencing. All study procedures will be completed in off-duty time as to not interfere with military duties.
