Brief Summary
The goal of this clinical trial is to test if a modified peer-based motivational intervention (the Military PAIRS; MPAIRS) is reasonable and practical for military contexts. The main questions it aims to answer are:
- Does it works to reduce SV?
- Does it works to reduce risky drinking? To test this, participants will answer questions about their SV history and risky drinking. Then they will be given MPAIRS. After 1 month, they will be asked about their SV history and risky drinking again.

Outcome Measures
Primary Outcomes (4)
Readiness to intervene
10 item scale scored on a 5 point likert type scale with higher value indicating they are more ready to intervene on behalf of the other member of the dyad in areas of concern for abuse. Modeled after: Center for Evidence-Based Practices at Case Western Reserve University (2010). Readiness Ruler. Center for Evidence-Based Practices, Case Western Reserve University.
In Phase 1, at baseline and 4 week follow up. In Phase 2, at baseline, 1 month follow up, 2 month follow up, and 3 month follow up.
Peer -Directed Bystander Behaviors Scale for Friends
44 item scale. The answers provided are yes/no/"I did not perceive an opportunity to do this" for each item in 3 different contexts (Friend, Stranger, Someone in Military). Each item is a situation that the participant may have been in to help someone in the past month. The participant reports if they did that helped, didn't help, or didn't have that situation for each context. Banyard, V. L., Moynihan, M. M., Cares, A. C., \& Warner, R. A. (2014). How do we know if it works? Defining measurable outcomes in bystander-focused violence prevention. Psychology of Violence, 4(1), 101-115.
In Phase 1, at baseline and 4 week follow up. In Phase 2, at baseline, 1 month follow up, 2 month follow up, and 3 month follow up.
Assault Protective Strategies
20 item scale. It is scored on a 4 point likert type scale with an option for "I prefer to not answer" and an option for "I did not perceive an opportunity to do this". The scale is made up of items of strategies that people do either before going out, or while they are out to reduce risk for sexual assault. The participant reports to what extent they use each strategy with a higher number meaning they use the strategy to a greater extent.
In Phase 1, at baseline and 4 week follow up. In Phase 2, at baseline, 1 month follow up, 2 month follow up, and 3 month follow up.
PBSS-20 Alcohol Protective Strategy
20 item scale. It is scored on a 6 point likert type scale. The scale is made up of items of different strategies people often use to protect against negative consequences of alcohol use. The participant reports to what extent they use each strategy with a higher number meaning they use the strategy to a greater extent. Treloar H, Martens MP, McCarthy DM. The Protective Behavioral Strategies Scale-20: improved content validity of the Serious Harm Reduction subscale. Psychol Assess. 2015 Mar;27(1):340-6. doi: 10.1037/pas0000071.
In Phase 1, at baseline and 4 week follow up. In Phase 2, at baseline, 1 month follow up, 2 month follow up, and 3 month follow up.
Secondary Outcomes (2)
Sexual Assault Experiences
In Phase 1, at baseline and 4 week follow up. In Phase 2, at baseline, 1 month follow up, 2 month follow up, and 3 month follow up.
Change in Drinking
In Phase 1, at baseline and 4 week follow up. In Phase 2, at baseline, 1 month follow up, 2 month follow up, and 3 month follow up.

Interventions
The intervention will use Motivational Interviewing's (MI) collaborative conversation style for strengthening commitment to change, to motivate and prepare service members to work together to reduce Sexual Violence (SV) risk. This intervention will target ways that the peer dyad may support, encourage, and share responsibility with one another in protecting against SV. The Peer-based MI (PMI) will then use the responsibility and relationship of peers as a framework to foster collaborative efforts to increase readiness and decrease barriers to helping behavior. As part of this, the PMI will focus on the identification and implementation of skills peers can use to help one another prevent SV. PMI will include a focused discussion of the ways drinking may impede helping efforts. Moreover, the PMI will encourage service members to identify personal, specific strategies for reducing the effects of alcohol on helping.
This single-session intervention, is designed to be delivered to peers in a group or dyad-based format, examines social determinants of health and wellness across a variety of domains. The intervention outlines a 6-step process for improving overall wellness. The CDC offers a number of handouts and other materials (e.g., peer dialogue exercises, data cards) that accompany the didactic material. In this study, the HWBA intervention will be delivered by a project interventionist. The session will be designed to be time equivalent (90 minutes) to the MPAIRs intervention. (Pember, 2018)
