Smartphone App to Reduce Drinking for Adults Experiencing Homelessness
This study is testing a smartphone app called Smart-T Alcohol to see if it can help adults experiencing homelessness reduce their alcohol consumption. The app provides on-demand content and personalized messages to help you cut down on drinking. You might be able to join if you are at least 18 years old, are receiving services at a shelter, and drink alcohol regularly. The study will compare the Smart-T Alcohol app to standard shelter-based treatment (Usual Care). Researchers will measure success by looking at how many drinks you have per week, how many days you have heavy drinking, and your total number of drinking days after 13 weeks.
- Study design
- This is a randomized controlled trial with 600 participants. You would be randomly assigned to either receive standard shelter-based treatment or the Smart-T Alcohol intervention in addition to standard care.
- What's involved
- You would complete a screening visit and use a smartphone app to answer four short daily surveys for one week. If eligible, you would then receive an 8-week intervention, followed by additional surveys and assessments at weeks 9, 13, and 26.
- Compensation
- Not stated in the trial record.
- Follow-up
- Participants will be followed for 26 weeks after enrollment, with assessments at weeks 9, 13, and 26.

What this trial measures
- Number of drinks per week13 weeks
The number of drinks per week reported during daily EMAs.
- Number of heavy drinking days13 weeks
Number of heavy drinking days reported in daily EMAs (defined in alignment with NIAAA guidelines as ≥ 5 drinks/day for men and ≥ 4 drinks/day for women).
- Total number of drinking days13 weeks
The total number of drinking days will be calculated using EMA data.
- Slopes of key drinking factors over time(e.g., urge, mood, alcohol availability, motivation)13 weeks
Analyses will determine the effects of tailored intervention messages (Smart-T app group) versus no intervention messages (Usual Care) on key drinking risk factors over time.
