Using a mobile app to reduce risky alcohol use and HIV risk

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to enhance an existing intervention called TRAC by integrating ecological momentary interventions (EMI) delivered through a mobile app. The app uses GPS tracking to identify when participants visit locations associated with risky drinking behaviors and sends real-time messages to encourage safer choices. Participants will be randomized into three groups to evaluate the effectiveness of the TRAC-ER intervention, which combines EMI messaging with traditional TRAC strategies. Data will be collected through surveys and breathalyzer readings after participants leave these locations to assess their behaviors.
