Impact de la prise de décision sur l’évolution des patients pris en charge pour trouble lié à l’usage de cannabis après 3 mois de traitement ambulatoire

Abstract : Background: studies have shown impaired performance on tests of decision -making capacities among patients with cannabis use disorder. This impaired decision-making might be a barrier to addiction treatment outcome response either through reduced compliance and/or reduced treatment efficacy. Objectives: the main goal of this study was to assess the impact of decision-making capacities on cannabis addiction treatment outcomes at 3 months and to explore possible mechanisms. Method: decision-making capacities were measured using the Iowa Gambling Task (IGT) before addiction treatment admission. Addiction was characterized with the Addiction Severity Index (ASI), DSM-5 diagnostic criteria and craving assessment. Treatment outcome was defined as change in the ASI Drug Composite Score (CS). Quantification of treatment service use was assessed by the Treatment Service Review (TSR) and ASI. A multivariate regression was used to control for potential confounders and explanatory variables. Results: 39 subjects were included. IGT net score at inclusion was significantly associated with improvement of ASI Drug CS at 3-month follow-up (ρ = -0.328; p = 0.045). This association was lost when adjusting for level of education. Conclusion: decision-making capacities as measured by the IGT might represent a prognostic factor among patients starting outpatient treatment for cannabis use disorder. Further studies are needed to determine how level of education influences this association.
