Alcohol use plays a central role in increased morbidity and mortality in this population, with some studies suggesting it plays a direct role in as many as 17% of deaths. Alcohol is also a leading cause of homelessness and contributes to its chronicity by inhibiting progress toward obtaining employment and a stable living environment. Shelter-based treatments are common, but compliance is often poor. There are many documented challenges to effectively implementing traditional evidence-based interventions in shelter settings. In the current project, we will conduct a randomized controlled trial. Adults currently experiencing homelessness who report hazardous alcohol use (N = 600) will be recruited from five shelters across the Dallas, TX and Oklahoma City, OK metropolitan areas. Individuals will attend screening and training visits, then complete one week of self-monitoring (via smartphone app) before being randomized to receive either standard shelter-based treatment (Usual Care; UC), or the Smart-T Alcohol intervention + UC. The Smart-T Alcohol intervention offers on-demand content and automated contextually tailored messages to reduce alcohol consumption. The intervention period will span eight-weeks (i.e., weeks 2-9), with follow-up assessments occurring at weeks 9, 13, and 26. All participants will complete brief daily smartphone-based surveys for 13 weeks. Aims of the project will be to assess the effects of the Smart-T Alcohol intervention on alcohol use and alcohol-related problems (Aim 1), intervention effects on key drinking risk indicators and their mediation of use outcomes (Aim 2), and identify specific subpopulations (e.g., women, racial\u002Fethnic minorities, younger adults; Exploratory Aim 3) for which the intervention is most effective. Findings will provide a rigorous evaluation of the efficacy of the Smart-T Alcohol intervention and guide future smartphone-based interventions for this population.",[29,30],"Alcohol Misuse","Homeless",[32,33,34,35],"Just In Time Adaptive Intervention","Mobile Health","homeless","ecological momentary assessment","RECRUITING","2026-04-27",{"date":39,"type":40},"2026-05-01","ACTUAL",{"date":42,"type":40},"2025-03-05",{"date":44,"type":22},"2029-04-30",{"name":46,"class":47},"University of Oklahoma","OTHER"]
