简要总结
This Phase 2 trial will to examine the efficacy of a brief dyad-based motivational interview (PAIRS MI) delivered to friend dyads with an active treatment-as-usual condition, and a 1-year follow-up.
详细描述
In this project the investigators will conduct a Phase 2 trial to test the efficacy of a friend-based motivational interview (FMI) compared to a treatment-as-usual (TAU) control, following participants over 1-year post-intervention (Aim 1.). With this trial the investigators also will address some key questions about FMI effects on target attitudes and behaviors (Aim 2.a.) that may be mechanisms of intervention outcome (Aim 2.b.). This includes Instrumental mechanisms (readiness, barriers, and assault protective behavior skills), and the dyadic relationship (closeness, collaboration between the friends in the dyad).
Aim 1. In a Phase 2 trial, the investigators will examine the efficacy of a friend-based motivational intervention (FMI) to reduce AISA risk relative to an active control condition over 1-year post-intervention.
The investigators will compare the FMI to a standard sexual assault prevention intervention widely used on U.S. college campuses. The investigators will use a three-level HLM, with repeated measures over one year (3, 6, 9, 12-month follow-up) nested within person (Level 2), and person nested within dyad (Level 3) to examine AISA outcomes. The investigators expect those in the FMI to report fewer incidences of AISA at follow-up assessments. Both AISA and assaults not involving alcohol will be examined.
Aim 2. Examine mechanisms (instrumental, relationship) of intervention effects. In this dyad-based FMI, an interdependent process may unfold that influences outcomes whereby the FMI influences AISA risk through a person's own change, as well as through their friend's change. It is important to distinguish these two processes as each may be an important part of intervention effects. Accordingly, with longitudinal Actor-Partner Interdependence Models (APIM, Cook & Kenny, 2005; Kenny & Ledermann, 2017) the investigators will test whether the intervention impacts mechanisms of change through actor (a person's own change), partner (friend's change) effects, or both (Aims 2a-2c).
Aim 2.a. Examine intervention effects on instrumental and relationships putative mediators, whether the putative predictors predict AISA.

结局指标
主要结局
Alcohol-Involved Sexual Assault
时间窗: This will be completed during Baseline, 1 month follow-up, 3 month follow-up, 6 month follow-up, 9 month follow-up, and 12 month follow-up
Revised Sexual Experiences Survey (R-SES) will be used to assess each social occasion with the target friend in the prior 2 weeks. Each item will be coded 1 (yes) or 0 (no), based on whether it happened to the woman/friend on each occasion that the pair socialized together.
Change in Drinking
时间窗: This will be completed during Baseline, 1 month follow-up, 3 month follow-up, 6 month follow-up, 9 month follow-up, and 12 month follow-up
Using a grid-based average assessment measure based in the Daily Drinking Questionnaire, participants will report on alcohol consumption. Higher scores indicate greater alcohol consumption.
次要结局
- Change in Readiness to Intervene(This will be completed during Baseline, 1 month follow-up, 3 month follow-up, 6 month follow-up, 9 month follow-up, and 12 month follow-up)
