The Kusa manga, a secondary prevention program for cannabis use in adolescence based on emotional regulation: Preliminary data

Abstract

Introduction

France is one of the European countries with the highest prevalence of cannabis use, particularly in adolescence. Emotional regulation (ER) is one of the major risk factor in the etiology and the maintenance of cannabis use disorder and therefore is a key target for prevention programs.

Objectives

This study aimed to evaluate the feasibility and the impact of a prevention program focusing on ER (especially on various emotional skills like awareness, emotional clarity and reactivity, ER strategies, and the level of emotional awareness) and on cannabis use among adolescents from various institutions.

Method

In total, 87 adolescents from various institutions were included. ER was assessed by the Emotion Regulation Questionnaire, the Difficulties in Emotion Regulation Scale, the Emotion Reactivity Scale and the Adolescent Levels of Emotional Awareness Scale; cannabis use was assess by the Cannabis Abuse Screening Test (CAST). All participants were assess before preventive intervention (T0) and four months after the end of the program (T1).

Results

Between T0 and T1, for all participants, there was an increase of emotional awareness, a decrease of emotional sensitivity, intensity and persistence, and an increase of the level of emotional awareness (total, self and others). There was no significant difference between T0 and T1 in CAST scores.

Conclusions

The prevention program showed encouraging results with a vulnerable group of adolescents in institutional care, particularly those from the Child Social Care (Aide sociale à l’enfance) and Child Forensic Institution (Protection judiciaire de la jeunesse) by showing an effect on different components of ER but not directly on cannabis use.
