Efficiency of Prevention Program Dedicated to Addictive Behaviors (PREVENTURE) of Vulnerable Teenagers

Summary

At the age of 17, in Brittany, 94.9% of adolescents have experimented alcohol consumption 78.1% within a month and 25.5% report repeated episodes of Intensive Punctual Alcohol. Among the potential explanatory factors of this worrying epidemiology, social and cultural factors induce a social valuation of alcohol consumption and drunkenness. There are also individual vulnerability factors, particularly important in adolescence between experimentation and the transition to regular use or even to alcohol use disorders. Despite the extent of the damage, there is currently little reliable data on effective primary prevention strategies for dealing with addictive behavior. Many prevention programs target age range in school settings, to delay or reduce use of psychoactive substances.

A meta-analysis on the impact of this prevention programs in school settings, concluded that most interventions are associated with no or little impact with respect to the goal of reducing psychoactive substances with teenagers.

Among existing programs, "PREVENTURE" has been evaluated in 5 trials with high-risk teenagers identified in schools settings, in different countries (Canada, Europe). The results show a clear and robust effect on reducing alcohol consumption. This program has not been tested outside the school setting and a recent review mention the need to make this program more accessible by targeting vulnerable groups and studying the impact of this program on this population.

The PREVADO study is a prospective, controlled, randomised, open-label study. After inclusion, the adolescent completes the questionnaire SURPS (Substance Use Risk Profile Scale).

The SURPS is self-report questionnaire that assesses four well-validated personality risk factors for substance misuse (Impulsivity, Sensation Seeking, Anxiety Sensitivity, and Hopelessness). There is a 23-item to which adolescents are asked to respond using a 4-point Likert scale ranging from "strongly agree" to "strongly disagree" : Hopelessness (7 items), Anxiety Sensitivity (5 items), Impulsivity (5 items), and Sensation Seeking (6 items).

Adolescents will be randomized into 2 groups (stratification on the 4 predominant risk personality types from the SURPS (Substance Use Risk Profile Scale) and on the recruitment modality) :

* Intervention group : teenagers follow the "PREVENTURE" program and routine cares
* Control group : teenagers follow routine cares
