Testing a Smartphone App to Help Adults Experiencing Homelessness Reduce Drinking Randomized Study Comparing Usual Shelter Care With Smart-T Alcohol Intervention

What this Trial Is About

Researchers are evaluating a smartphone-based intervention called Smart-T Alcohol designed to reduce alcohol use among adults experiencing homelessness who report hazardous drinking. This randomized controlled trial will compare the effects of the Smart-T Alcohol intervention plus usual shelter-based care versus usual care alone. The study aims to assess alcohol consumption, drinking risk factors, and the interventions effectiveness in specific subgroups such as women and younger adults. Participants will be recruited from five shelters in Dallas, TX and Oklahoma City, OK, and will complete screening and training visits. They will use a smartphone app to complete daily surveys for one week before randomization. The intervention period lasts eight weeks, during which participants receive either usual care or usual care plus the Smart-T Alcohol app that delivers on-demand tips and tailored messages based on daily survey responses to support drinking reduction goals. Follow-up assessments occur at 9, 13, and 26 weeks post-enrollment. Throughout the 13-week study period, all participants complete brief daily smartphone surveys to track alcohol use and related factors like mood and motivation. Researchers will monitor drinking patterns, alcohol-related problems, and changes in risk indicators. Data collection includes app-based assessments and follow-up visits at shelters or via phone. The study also documents engagement with existing treatment services, and participants reporting heavy or high-intensity drinking receive additional referrals for support.
