Alcohol Consumption, Intention Implementation and Mindfulness Meditation (ADUC-Volet 3 " Prevention ")

Context. The emergence of new problematic alcohol consumption practices among young people requires new dynamics in prevention strategies. In this context, the ADUC project (Alcohol and Drugs at the University of Caen) aims to develop a better understanding of alcohol consumption, and in particular the practice of binge drinking (BD), in order to develop relevant and adapted prevention tools. The first step, logistically supported by the University of Caen, consisted in identifying the levels of alcohol consumption of students, the prevalence of binge drinking, and their determinants. Based on more than 7000 participants interviewed, it essentially demonstrated 1) an alarming 22% prevalence of BD among students and 2) four main psychological determinants, namely impulsivity (i.e., the tendency of individuals to act prematurely without fully weighing the consequences of their action), subjective norm (i.e., perception of what is done and/or approved by peers), drinker identity (i.e., how the individual defines him/herself as a drinker), and motivations to drink (social, compliance, enhancement, or coping motivations).

Objective. The ALCOMEDIIT study (IRESP funding; Agreement 20II31-00 - ADUC part 3) is a randomized controlled trial that focuses on the specific determinant of impulsivity. The main objective of this experiment in social psychology is to validate a program for the prevention of BD practices based on motivational interviewing (MI) associated with intention implementation (II) and mindfulness meditation (MBM) in a student environment.

Materials and Methods. This study will include 120 healthy subjects who will be students at the University of Caen Normandy. They will be people who consume alcohol, having a BD score > 1 in the month preceding the inclusion but not presenting any specific disorder. The trial will be proposed to them by e-mail and the people who meet the inclusion criteria will join either a control group which will benefit from a MI, or an experimental group which will also benefit from a MI but which will be associated with an initiation to MBM with II (initial visit T0). In order to measure the effectiveness of the prevention device in terms of reducing the use of BD, a follow-up at 1 month (T1) as well as a follow-up at 6 months (T6; exploratory) will be proposed to all participants. The total duration of this research protocol is one year.

Hypothesis tested. The aim of this work is to evaluate the interest of associating mindfulness meditation practices, practices implemented to optimize their use, with a motivational interview in a prevention program aiming at reducing alcohol use and the practice of BD in the student population.
