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.
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.
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.
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.
饮酒与性侵犯（SA）受害情况在大学校园中常常同时出现，预防项目理想情况下应通过综合的循证干预措施来解决这两个公共卫生问题。“积极改变”（Positive Change©）是一种基于网络的干预措施，它结合了关于酒精和性侵犯的内容，并根据参与者的性别认同和性取向提供个性化的规范反馈。基于之前的项目评估，本研究考察饮酒作为“积极改变”（Positive Change©）干预效果的中介因素，对与酒精相关的后果、性侵犯受害可能性以及性侵犯受害严重程度的影响。
年龄在18 - 25岁、过去一个月有大量饮酒行为的大学生（n = 165）参与了“积极改变”（Positive Change©）的一项试点随机对照试验。参与者完成了一项基线调查，被随机分配接受“积极改变”（Positive Change©）干预（n = 83）或仅接受评估的对照组（n = 82），并完成了一项为期3个月的随访调查。
进行了两项独立的路径分析。每周饮酒量介导了“积极改变”（Positive Change©）在减少与酒精相关后果和降低性侵犯可能性方面的效果，但并未介导性侵犯严重程度的降低。
研究结果表明，利用个性化规范反馈来干预饮酒和性侵犯的简短综合项目，可能是减少大学生饮酒的理想方式，而这反过来可能降低大学生遭受性侵犯的风险。
