ENGLISH:
The Moti-4 intervention, in which motivational interviewing, self-monitoring, and strengthening behavioral control are used, was developed in the Netherlands in response to several rapid assessments of problematic use of cannabis among vulnerable adolescents. The main goal of the study reported in this article was to determine whether the Moti-4 intervention was able to reduce two outcome measures pertaining to the level of cannabis use; the amount of Euros spent a week on cannabis and the mean number of cannabis joints (cigarettes) smoked in a week. In a randomized controlled trial (RCT) with a 6-month follow-up, 27 trained Dutch prevention workers recruited 71 Moti-4 participants and 60 controls assigned to usual care. Participants were Dutch youth aged 14-24 years who had used cannabis during the preceding month. At baseline (T0), post-test (T1) and 6-month follow-up (T2), participants completed a questionnaire with 51 items. The 27 prevention workers also completed a checklist to assess the fidelity of delivering each item to each participant in the Moti-4 protocol. Multilevel and binary logistic regression was used to assess the impact of the prevention worker and 14 participant variables on the likelihood of drop-out. Mean scores for cannabis use outcome measures by Moti-4 participants and controls at baseline, T1 and T2 were compared using paired sample t-tests. Top-down multiple regression was used to assess relationships between Moti-4 and 13 other variables on the one hand and changes in weekly cannabis use at T1 and T2 on the other. The Moti-4 experimental condition had a significant and positive influence in reducing the level of expenditure on cannabis (p Highlights: Moti-4 is a tailored, individual brief intervention for youth problematic cannabis use. Moti-4 had a significant positive influence on cannabis use (almost 50% reduction). This effect was still present at the 6 month follow-up. Moti-4 is an effective preventive intervention to address adolescent cannabis use.

L'étude a été réalisée aux Pays-Bas auprès d'un échantillon de 71 participants entre 14 et 24 ans, ayant rapporté une consommation de cannabis le mois précédant l'inclusion et 60 individus contrôle. L'étude met en évidence une association entre l'intervention basée sur l'entretien motivationnel, un renforcement du contrôle comportemental et l'auto-évaluation, et une réduction des consommations avec également des dépenses significativement moins importantes en termes d'achat de cannabis comparées à la population contrôle, à 6 mois (p |
