Can a phone app keep you sober? new study tests Anti-Alcohol training
NCT ID NCT03952429
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a smartphone app designed to help people recovering from alcohol dependence avoid relapse. The app uses a training game to change unconscious habits that make people reach for alcohol. 600 participants used either the active training or a placebo version. The goal was to see if the app reduces craving and lowers relapse rates after leaving inpatient care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- smartphone app with cognitive bias modification training
- What this could lead to
- If it works, this could provide an easy, at-home tool to help people recovering from alcohol dependence stay sober and reduce relapse rates.
- What could go wrong
- This is a completed study, but the app only targets unconscious biases and may not work for everyone. Relapse rates remain high, and the benefit seen so far is modest (4-8% reduction).
