title: Psychological predictors of retention in a low-threshold methadone maintenance treatment for opioid addicts: a 1-year follow-up study.
abstract: This study investigated the role of psychological variables and judicial problems in treatment retention for a low-threshold methadone program in Montreal, Canada. Logistic regression analyses were computed to examine associations between psychological variables (psychological distress, self-esteem, stages of change), criminal justice involvement, and treatment retention for 106 highly-disorganized opioid users. Higher methadone dosage was associated with increased odds of treatment retention, whereas criminal charges and lower self-esteem decreased these odds. Psychological variables could be identified early in treatment and targeted to increase potential treatment retention. Financial support for this study was provided by the Fonds de Recherche en Santé du Québec.
