Ninety cannabis-dependent adults seeking treatment were randomly assigned to receive cognitive-behavioral therapy, abstinence-based voucher incentives, or their combination. Treatment duration was 14 weeks, and outcomes were assessed for 12 months posttreatment. Findings suggest that (a) abstinence-based vouchers were effective for engendering extended periods of continuous marijuana abstinence during treatment, (b) cognitive-behavioral therapy did not add to this during-treatment effect, and (c) cognitive-behavioral therapy enhanced the posttreatment maintenance of the initial positive effect of vouchers on abstinence. This study extends the literature on cannabis dependence, indicating that a program of abstinence-based vouchers is a potent treatment option. Discussion focuses on the strengths of each intervention, the clinical significance of the findings, and the need to continue efforts toward development of effective interventions.
90名寻求治疗的大麻依赖成年人被随机分配接受认知行为疗法、基于禁欲的代金券激励措施或两者结合。治疗持续时间为14周，并在治疗后12个月评估结果。研究结果表明：（a）基于禁欲的代金券在治疗期间能有效地促使长时间持续戒除大麻；（b）认知行为疗法并未增强这种治疗期间的效果；（c）认知行为疗法增强了代金券对禁欲的初始积极效果在治疗后的维持。这项研究扩展了关于大麻依赖的文献，表明基于禁欲的代金券计划是一种有效的治疗选择。讨论聚焦于每种干预措施的优势、研究结果的临床意义以及继续努力开发有效干预措施的必要性。
