Study Summary
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. Ecological momentary assessments (EMAs) that involve repeated assessment of thoughts/mood/behaviors (e.g., via smart phone) is currently the most accurate way to assess individuals in real-time in their natural environments. Advances in smartphone technology also allow for the collection of continuous geolocation and other passive sensing data. Thus, researchers can now link environmental risks and protective factors to outcomes, without reliance on subjective reporting alone. Building on prior work, this study will use a three-phase study to develop and test a "just in time" adaptive intervention to reduce alcohol use in homeless men and women. Phase I will use smartphones and passive sensing technologies to monitor geolocation, psychosocial variables (e.g., stress, affect, urge to drink), and alcohol use in a group of 80 homeless adults with an AUD who are receiving shelter-based treatment. Phase I will identify environmental (i.e., geolocation), cognitive, and behavioral antecedents of alcohol use over 4 weeks. Phase II will use this information to create a risk algorithm and tailored treatment messages that anticipate and intervene to prevent drinking. The resulting app will assess imminent risk of alcohol use after each EMA and will deliver relevant treatment messages that match a person's current risk factors. Phase III will test the feasibility, acceptability and preliminary efficacy of the app in a sample of 40 homeless adults with an AUD who receive the EMA plus treatment messages over 4 weeks. Drinking will be determined via self-report, supplemented by a transdermal alcohol sensor (i.e., SCRAM) worn by participants. This project will be the first to combine geolocation and psychosocial variables to identify real-time antecedents of drinking. If effective,
