What this research studies

You would use an Android version of the A-CHESS support app that collects personal sensing data from your phone. A machine-learning model will use those sensing signals to predict when you might be at higher risk of lapsing and generate tailored messages. The team will test different message components (for example timing, wording, and how the risk is presented) to see which ones keep people using the app and help them stay sober. The study will track app engagement and drinking outcomes over time to compare approaches.

Who could benefit from this research

Good fit: Adults (21+) with alcohol use disorder who are willing to use an Android smartphone app and share phone-sensing data are ideal candidates.

Not a fit: People without an Android phone, unwilling to use an app or share phone data, or who need in-person treatment only may not benefit from this approach.

Why it matters

Potential benefit: If successful, the app could give timely, personalized support on your phone to reduce risky drinking and prevent relapse.

How similar studies have performed: Clinician-delivered relapse prevention and some digital apps have helped people, and early machine-learning lapse prediction work is promising though personalized message delivery is relatively new.
