Expanding the uSafeUS Mobile App to Reduce Alcohol-Involved Sexual Assault on College Campuses

项目摘要 这个R34应用程序旨在开发和测试一个创新的移动的应用程序（应用程序），以减少大学生 真实的饮酒和性侵犯风险。超过75%的校园性侵犯涉及酒精，但存在 为普及服务而设计的校园酒精和SA预防工作往往是孤立的，在其 为学生提供即时帮助以降低风险的能力。智能手机应用程序是 大学生的生活，并越来越多地用于从事实时酒精预防学生;然而， 没有一个国家将预防酗酒和性侵犯纳入单一的跨领域工具。本研究 通过扩展一个有前途的校园性侵犯预防和应对应用程序来解决这一差距 （uSafeUS®）包括基于证据的酒精危害减少工具和实时消息传递，以支持 学生在最需要的时候使用保护性行为策略（PBS）。的 uSafeUS应用程序，目前在24个美国大学校园使用，利用性侵犯PBS（例如，共享电流 地点和预期返回家中的时间）作为主要的风险降低机制， 学生在酒精存在的社交环境中使用，但现有的功能都没有直接解决 酒精消费。该项目将利用现有的uSafeUS基础设施和经过验证的以用户为中心的 开发过程，以扩大应用程序的功能，包括互动饮料跟踪和个性化的反馈 信息传递，以减少酒精消费和增加PBS的使用。扩展的应用程序（uSafeUS+）将是测试版 在公开试用中进行测试，以收集最终用户（学生）和校园管理员对该应用程序的 在实地的实际效用以及拟议的执行和评价计划的可行性。这将是 随后进行了一项初步的3组随机对照试验（N = 90，30/组），以检查可接受性、可行性 和uSafeUS+的初始疗效，相对于活性（uSafeUS）和仅评估对照组。短期 从长远来看，目前的研究结果将优化计划的应用程序，并告知一个完全动力的多站点混合 有效性试验。从长远来看，研究结果有可能为移动健康的使用提供信息 整合预防工具的方法，以普遍提供个性化的真实的时间预防大学 酗酒和性侵犯经常同时发生的校园

PROJECT SUMMARY This R34 application aims to develop and test an innovative mobile application (app) to reduce college student drinking and sexual assault risk in real time. Over 75% of campus sexual assaults involve alcohol, yet existing campus alcohol and SA prevention efforts designed for universal delivery are often siloed and limited in their ability to provide students with in-the-moment assistance to reduce risk. Smartphone apps are an integral part of college student life and are increasingly used to engage students in real-time alcohol prevention; however, none have integrated alcohol and sexual assault prevention into a single cross-cutting tool. This study addresses this gap by expanding a promising campus sexual assault prevention and response app (uSafeUS®) to include evidence-based alcohol harm reduction tools and real-time messaging to support students’ use of protective behavioral strategies (PBS) in the moments when they most need them. The uSafeUS app, currently in use on 24 US college campuses, utilizes sexual assault PBS (e.g., sharing current locations and an expected return home time with trusted peers) as the primary risk reduction mechanism for students to use in social contexts where alcohol is present, yet none of the existing features directly address alcohol consumption. This project will leverage the existing uSafeUS infrastructure and a proven user-centered development process to expand app features to include an interactive drink tracker and personalized feedback messaging to reduce alcohol consumption and increase PBS use. The expanded app (uSafeUS+) will be beta tested in an open trial to gather end-user (student) and campus administrator feedback about the app’s practical utility in the field and feasibility of the proposed implementation and evaluation plans. This will be followed by a pilot 3-arm randomized controlled trial (N = 90, 30/arm) to examine the acceptability, feasibility, and initial efficacy of uSafeUS+, relative to active (uSafeUS) and assessment-only control groups. In the short term, results from the current study will optimize the planned app and inform a fully powered multi-site hybrid effectiveness-implementation trial. Longer term, findings have the potential to inform the use of mHealth approaches for integrating prevention tools to universally deliver personalized real time prevention on college campuses where heavy drinking and sexual assault often co-occur.
