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.

项目概要 减少大学生危险饮酒的简短动机干预措施 (BMI) 已十分成熟，但 居住在弱势社区且非全日制大学的新兴成人 (EA) 有风险饮酒者的需求 学生被忽视了。他们往往获得奖励机会的机会更加有限，成人 提供亲社会替代酗酒的角色和活动。当与透视结合时 许多环境评估的典型时间范围，这表明需要采取干预措施，不仅增强 减少饮酒，但引导 EA 采用酗酒的替代方案，并将其行为导向 更长期的积极目标。在行为经济学（BE）的指导下，拟议的研究将传播和 评估将 BMI 元素与无物质活动相结合的简短激励性 BE 干预措施 会议表明，可以通过增加未来导向和参与亲社会替代方案来减少饮酒。 干预措施将使用适合社交网络运营的 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，因此采用同伴驱动的抽样方法 （受访者驱动抽样 [RDS]）将用于招募 500 名年龄在 18-28 岁的社区居住的 EA 进行调查 将干预措施与教育/评估对照进行比较的整群随机对照试验 健康）状况。饮酒习惯和问题、BE 结果预测因素和社交网络将在 基线以及 1、6 和 12 个月的随访。干预效果和行为改变机制将 检查了。酒精需求减少，延迟折扣以及未来干预后有利的转变 定向、无物质活动与涉及物质的活动以及使用保护性行为策略 减少与饮酒相关的危害预计可以调节干预效果。社交网络分析将评估 干预措施是否会削弱个人饮酒的网络推广。该研究将是第一个测试 基于网络的戒酒干预措施，重点关注 BE 原则，并使用数字 RDS 覆盖社区 用于干预的住宅 EA。该研究将翻译和测试BE变革的调解者和调节者，以及 数字干预对于服务不足的社区风险群体具有很大的影响力和可扩展性。
