PROJECT SUMMARY Brief motivational interventions (BMIs) to reduce risky drinking in college students are well established, but the needs of emerging adult (EA) risky drinkers who live in disadvantaged communities and are not fulltime college students have been neglected. They tend to have more constrained access to rewarding opportunities, adult roles, and activities that present pro-social alternatives to heavy drinking. When coupled with the foreshortened time horizons typical of many EAs, this suggests the need for interventions that not only enhance motivation to reduce drinking, but guide EAs to engage in alternatives to heavy drinking and orient their behavior toward longer-term positive goals. Guided by behavioral economics (BE), the proposed study will disseminate and evaluate a brief motivational BE intervention that combines BMI elements with the Substance Free Activity Session shown to reduce drinking by increasing future orientation and engagement in pro-social alternatives. The intervention will be delivered using a digital platform appropriate for EAs whose social networks operate through such communications. Because peers influence substance use, a peer-driven sampling method (Respondent Driven Sampling [RDS]) will be used to recruit 500 community-dwelling EAs ages 18-28 for a cluster randomized controlled trial that compares the intervention with an educational/assessment control condition. Drinking practices and problems, BE outcome predictors, and social networks will be assessed at baseline and at 1, 6, and 12-month follow-ups. Intervention efficacy and behavior change mechanisms will be examined. Reduced alcohol demand and delay discounting and favorable post-intervention shifts in future orientation, substance-free vs. substance-involved activities, and use of protective behavioral strategies to reduce drinking-related harms are predicted to mediate intervention effects. Social network analysis will assess whether the intervention attenuates network promotion of individual drinking. The study will be the first to test a web-based alcohol reduction intervention focused on BE principles and to use digital RDS to reach community- dwelling EAs for intervention. The study will translate and test BE mediators and moderators of change, and the digital intervention has high potential for reach and scalability with under-served community risk groups.

项目摘要 减少大学生危险饮酒的简短动机干预（BMI）已经建立，但 生活在弱势社区且不是全日制大学的新兴成年（EA）危险饮酒者的需求 学生被忽视了。他们往往有更多的限制获得奖励的机会，成年人 角色和活动，提出了亲社会的替代酗酒。当与被缩短的 这表明，需要采取干预措施，不仅要增强动机， 减少饮酒，但引导EA从事替代大量饮酒，并将其行为导向 长期的积极目标。在行为经济学（BE）的指导下，拟议的研究将传播和 评估结合BMI元素和无物质活动的简短动机性BE干预 会议表明，通过增加未来的方向和参与亲社会的替代品，以减少饮酒。 干预将使用适合于其社交网络运行的EA的数字平台进行 通过这样的沟通。由于同伴影响物质使用，同伴驱动的抽样方法 （受访者驱动抽样[RDS]）将用于招募500名18-28岁的社区居住的EA， 比较干预与教育/评估对照的随机对照试验 条件饮酒习惯和问题、BE结果预测因素和社交网络将在 基线和1、6和12个月随访时。干预效果和行为改变机制将是 考察减少酒精需求和延迟折扣以及未来有利的干预后转变 定向，无物质活动与涉及物质活动，以及使用保护性行为策略， 减少与饮酒有关的危害预计会介导干预效果。社交网络分析将评估 干预是否削弱了个人饮酒的网络推广。这项研究将是第一个测试一个 基于网络的酒精减少干预，重点是BE原则，并使用数字RDS到达社区- 居住的环境影响评估进行干预。这项研究将翻译和测试BE调解人和调解人的变化， 数字干预措施在服务不足的社区风险群体中具有很大的普及潜力和可扩展性。
