Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

This study is a randomized controlled trial comparing two parallel groups. This is a comparative study of superiority that evaluates the efficacy of using an interventional smartphone application,in reducing main problematic substance use/addictive behavior after 4 weeks, and after 4 months among participants requesting treatment for substance or behavioral addiction.

Primary Study Purpose

OTHER

Blinding Strategy

TRIPLE

Participants Caregivers Investigators

After randomization, the application will be installed on participant's smartphone (or smartphone loaned for the study).

Randomization code will unlock one of the 2 versions of the application:

* Restricted version (only EMA) for control group
* Full interventional (active) version (EMA + EMI) for experimental group

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental group

participants will receive and use during 4 weeks the full interventional version of the smartphone application (combining EMA + EMI) targeting craving and personal situations at risk for use

Group Type EXPERIMENTAL

Smartphone application

Intervention Type OTHER

Ecological Momentary Assessment (EMA)

: ambulatory assessment of behaviors/symptoms in real-time on smartphones

control group

: participants will receive and use a restricted version of the smartphone application (only EMA: 4 electronic questionnaires per day to assess main problematic substance use / addictive behavior) during 4 weeks
