Peer Influences in Alcohol and Sexual Violence Among Marines Dyads

United States320 participantsStarted 2026-03-18

Plain-language 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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
