The aim of this study was to evaluate the efficacy of a brief motivational enhancement therapy in reducing cannabis use and cannabis-related problems in a population of non-treatment-seeking adolescent cannabis users. In a randomized controlled trial, 40 young people (aged 14-19 years) were randomly assigned to either a two-session brief intervention or a 3-month delayed-treatment control condition. The intervention consisted of a detailed assessment and a session of motivational enhancement therapy. An additional optional discussion of skills for reducing or quitting cannabis use was offered if a participant was interested in discussing these issues. Primary outcome measures were changes in days of cannabis use, mean quantity of cannabis used weekly, and number of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition dependence symptoms reported. Significantly greater reductions on these measures were found in the Adolescent Cannabis Check-up group at 3-month follow-up. Between-group effect sizes were moderate. The approach is acceptable to participants and merits further evaluation with this difficult to reach population.
本研究的目的是评估一种简短的动机增强疗法在减少非寻求治疗的青少年大麻使用者群体中使用大麻及与大麻相关问题方面的疗效。在一项随机对照试验中，40名年轻人（年龄在14 - 19岁之间）被随机分配到两阶段简短干预组或3个月延迟治疗对照组。干预包括详细评估和一次动机增强治疗。如果参与者有兴趣讨论这些问题，还会提供关于减少或戒除大麻使用技能的额外可选讨论。主要结局指标包括大麻使用天数的变化、每周使用大麻的平均量以及报告的《精神障碍诊断与统计手册》第四版依赖症状数量。在3个月随访时，青少年大麻检查组在这些指标上的减少幅度显著更大。组间效应大小为中等。该方法为参与者所接受，值得对这个难以接触到的群体进行进一步评估。
