What this trial studies
This project evaluates the effectiveness of a smartphone application designed to assist individuals struggling with substance use and behavioral addictions. Developed by the University of Bordeaux's Sanpsy Lab, the app aims to manage cravings and identify individual predictors of addictive behavior. Participants will be recruited from specialized addiction treatment centers and will use the app to help reduce or stop their substance use. The application also monitors concurrent substance use to prevent addiction transfers.
Why it matters
Potential benefit: If successful, this app could provide a convenient and personalized tool for individuals seeking to manage their cravings and reduce addictive behaviors.
How similar studies have gone: Previous studies have shown promise in using technology to support addiction treatment, but this specific approach is relatively novel.
