About

Test the Efficacy of a smartphone application designed to manage craving and individual predictors of substance use / addictive behavior among individuals with addictive disorders

Full description

This translational project is the clinical application of research results from the University of Bordeaux, Sanpsy Lab, CNRS USR3413 - on individual predictors of substance use. This project will test the efficacy of a smartphone application to help subjects concerned about reducing or stopping their substance use / behavioral addiction.

This new therapeutic tool, designed by University of Bordeaux, Sanpsy Lab, CNRS USR3413 - to manage craving and individual predictors of use, will offer the possibility of an easy to-use and personalized intervention accessible to the greatest number of subjects.

Based on our previous results that supports that, for all types of addiction, craving and individual cues are a significant drive for use in people with addiction, the application tested in this study was designed to be used among people presenting various types of addiction (substance and behavioral addictions). The application will also evaluate all concurrent substance uses and addictive behaviors to identify and prevent risk of addiction transfers.
