PROJECT SUMMARY/ABSTRACT Homeless adults are 8 times as likely to be alcohol dependent compared with adults in the general population, yet few studies have examined the precipitants of alcohol use in this vulnerable population. This lack of information is a barrier to developing effective alcohol treatments for homeless adults, a population that is often excluded from clinical trials. R34 AA024584-01A1 is developing and testing a “just-in-time” adaptive smartphone intervention to reduce alcohol use in homeless men and women. We have completed Phase 1 (identification of “in-the-moment” risk factors that predict imminent drinking) and are nearly finished with Phase 2 (development of the prediction algorithm, treatment messages, and an app to deliver messages based on the risk of “imminent drinking” within four hours). In Phase 3, we will test the feasibility, acceptability, and preliminary efficacy of the app in a new sample of homeless adults. Following public health recommendations around COVID-19, we began to curtail our human subjects activities in late February, 2020. To comply with university directives, we ceased human subjects activities on 3/17/20. We expect to resume human subjects research in July, 2020. Disruptions from COVID-19 have resulted in an estimated 4 months of delay from a human subjects perspective; the current supplement request is necessary to complete Phase 3 (Aim 3) of the project.

项目摘要/摘要 无家可归的成年人的饮酒可能是一般人口中的成年人的8倍， 然而，很少有研究检查了这种脆弱人群中酒精使用的沉淀物 信息是为无家可归成年人开发有效的酒精治疗的障碍，这通常是 R34 AA024584-01A1不包括临床试验。 智能手机干预以减少无家可归者的酒精使用。 （识别预测即将饮酒的“时刻”风险因素），并且整齐地完成了阶段 2（开发预测算法，处理消息和应用程序，以根据该消息传递消息 在第3阶段的“即将饮酒”的风险。 该应用程序在新的无家可归成年人中的初步疗效。 1920年2月下旬，我们开始限制我们的人类臣民。 大学指令，我们在3/17/20停止了人类活动。 2020年7月的研究。与19 Covid-19的中断导致估计有4个月的延迟 人类的观点； 项目。
