The purpose of this paper is to provide a preliminary evaluation of treatment outcomes, retention and client satisfaction following a 12-week combined cognitive behavioural therapy (CBT) and motivational enhancement therapy (MET) group treatment for cannabis use disorder (CUD) delivered in an outpatient setting. Implementation of the program is also described.
A retrospective observational cohort study was conducted using data collected from medical records and self-report assessments. Participants were treatment-seeking cannabis users at the Centre for Addiction and Mental Health, Toronto. Cannabis use, cannabis-related problems, craving, withdrawal symptoms, self-efficacy for remaining abstinent, depression and anxiety were assessed pre- and post-treatment. Treatment retention was calculated by inspecting clinic attendance records, and client satisfaction was evaluated using an anonymous feedback survey. Potential predictors of treatment outcomes and retention were investigated in exploratory analyses.
Cannabis use was lower and days of abstinence higher post-treatment (vs pre-treatment). Post-treatment improvements in cannabis-related problems, craving, withdrawal symptoms, self-efficacy and mood were also observed. Completion of group treatment (⩾75% of sessions attended) was 57% and moderate levels of treatment satisfaction were reported.
This study provides preliminary evidence that a 12-week combined CBT and MET treatment for cannabis use disorder delivered in a novel group setting improves cannabis use outcomes. Potential predictors of reduced cannabis use and retention were identified. Future controlled studies are warranted, and strategies for increasing retention should be explored.
本文旨在对在门诊环境中为大麻使用障碍（CUD）患者提供的为期12周的认知行为疗法（CBT）与动机强化疗法（MET）联合小组治疗后的治疗效果、留存率及患者满意度进行初步评估。本文还介绍了该项目的实施情况。
采用回顾性观察队列研究，数据收集自病历和自我报告评估。参与者为多伦多成瘾与心理健康中心寻求治疗的大麻使用者。在治疗前和治疗后评估大麻使用情况、与大麻相关的问题、渴望程度、戒断症状、保持戒断的自我效能感、抑郁和焦虑情况。通过检查门诊出勤记录计算治疗留存率，并使用匿名反馈调查评估患者满意度。在探索性分析中研究治疗效果和留存率的潜在预测因素。
治疗后大麻使用量降低，戒断天数增加（与治疗前相比）。治疗后在与大麻相关的问题、渴望程度、戒断症状、自我效能感和情绪方面也有改善。小组治疗的完成率（参加 sessions 的⩾75%）为57%，报告的治疗满意度处于中等水平。
本研究提供了初步证据，表明在一种新型小组环境中为大麻使用障碍患者提供的为期12周的CBT与MET联合治疗可改善大麻使用结果。确定了大麻使用减少和留存率的潜在预测因素。未来有必要进行对照研究，并应探索提高留存率的策略。
