Abstract

Purpose

Alcohol use and sexual assault (SA) victimization often co-occur on college campuses, and prevention programs should ideally address both of these public health issues with integrated evidence-based interventions. Positive Change© is a web-based intervention with integrated content on alcohol and SA using personalized normative feedback tailored by participant gender identity and sexual orientation. Building from previous program evaluations, the current study examines alcohol use as a mediator for the intervention effects of Positive Change© on alcohol-related consequences, SA victimization likelihood, and SA victimization severity.

Methods

College students (n = 165) aged 18–25 who engaged in heavy episodic drinking in the past month were enrolled in a pilot randomized controlled trial of Positive Change©. Participants completed a baseline survey, were randomly assigned to receive Positive Change© (n = 83) or an assessment only control (n = 82) and completed a 3-month follow-up survey.

Results

Two separate path analyses were conducted. Drinks per week mediated the effect of Positive Change© to reduce alcohol-related consequences and reduce SA likelihood, but did not mediate reduced SA severity.

Conclusions

Findings suggest that brief well-integrated programs utilizing personalized normative feedback for alcohol use and SA may be ideal for reducing alcohol use, which in turn may reduce risk of SA victimization among college students.

减少饮酒作为积极变化对酒精和暴力相关干预效果的机制©

目的：在大学校园中，酒精使用和性侵犯（SA）受害者经常同时发生，预防项目应该通过综合循证干预措施来解决这两个公共卫生问题。积极改变©是一项基于网络的干预措施，其中整合了酒精和SA的内容，使用根据参与者性别认同和性取向量身定制的个性化规范反馈。基于先前的项目评估，本研究考察了酒精使用作为积极改变©对酒精相关后果、SA受害可能性和SA受害严重程度的干预效果的中介。方法采用Positive Change©随机对照试验方法，选取165名18-25岁的大学生为研究对象。参与者完成基线调查，随机分配接受积极改变©（n = 83）或仅评估对照组（n = 82），并完成3个月的随访调查。结果分别进行了两次路径分析。每周饮酒介导Positive Change©减少酒精相关后果和降低SA可能性的效果，但不介导SA严重程度的降低。结论：研究结果表明，利用个性化规范的酒精使用和SA反馈的简短整合方案可能是减少酒精使用的理想方案，这反过来可能降低大学生SA受害的风险。
