Abstract
Objective The aim of this study was to conduct a randomized test comparing 2 multicomponent, contingency management interventions, 1 with and 1 without a full parent training curriculum, and an individual treatment for adolescent cannabis use disorders. Method A total of 153 adolescents who met DSM-IV criteria for cannabis abuse or dependence were randomized to motivational enhancement therapy/cognitive-behavioral therapy (MET/CBT), MET/CBT+abstinence-based contingency management (CM), or MET/CBT+CM+Parent Training (PT). Results Overall, during treatment, abstinence was greater for youth receiving clinic- and home-based CM without PT compared to those who received individual MET/CBT. There was no additional benefit of the full PT curriculum on marijuana use, youth externalizing problems, or parenting. Conclusion These results suggest that clinic- plus home-based CM for cannabis use disorders can increase rates of abstinence during treatment over and above an evidence-based treatment (individual MET/CBT), but in this study the addition of a comprehensive parenting training curriculum did not further enhance efficacy.
