Testing a Smartphone App to Help Manage Craving and Reduce Substance or Behavioral Addictions in Adults

What this Trial Is About

Researchers are evaluating the effectiveness of a smartphone application designed to help people with substance use and behavioral addictions manage cravings and individual triggers for addictive behavior. This project builds on research from the University of Bordeaux, focusing on personalized intervention to reduce or stop substance use and addictive behaviors. The app is intended for people with various types of addictions and also assesses the risk of addiction transfers by monitoring concurrent substance use and behaviors. Participants are randomly assigned to one of two groups. One group uses the full version of the smartphone app for four weeks, which combines Ecological Momentary Assessment EMA with Ecological Momentary Intervention EMI to target cravings and risky personal situations. The other group uses a restricted version of the app for four weeks, which only includes EMA through four daily electronic questionnaires evaluating their main problematic substance use or addictive behavior. During the study, participants will be monitored for changes in their main addictive behavior over four weeks. Researchers will also assess addiction severity, craving levels, and usage patterns using questionnaires and daily app responses. Follow-up evaluations will happen at one and four months to measure the apps impact, feasibility, and acceptability. The total participation includes the four-week app usage period plus follow-up assessments, with safety monitored throughout the study.
