This study assessed whether contingent incentives can be used to reinforce cocaine abstinence in dependent outpatients. Seventy cocaine-dependent outpatients were randomized into 2 conditions. All participants received 24 weeks of treatment and 1 year of follow-up. The treatment provided to all participants combined counseling based on the community reinforcement approach with incentives in the form of vouchers exchangeable for retail items. In 1 condition, incentives were delivered contingent on cocaine-free urinalysis results, whereas in the other condition incentives were delivered independent of urinalysis results. Abstinence-contingent incentives significantly increased cocaine abstinence during treatment and 1 year of follow-up compared with noncontingent incentives.

这项研究评估了是否可以使用或有激励措施来加强依赖门诊患者的可卡因戒断。70名可卡因依赖型门诊患者被随机分为2种情况。所有参与者均接受了24周的治疗和1年的随访。向所有参与者提供的治疗将基于社区强化方法的咨询与可兑换零售商品的优惠券形式的激励措施相结合。在1种情况下,激励措施取决于无可卡因的尿液分析结果,而在其他情况下,激励措施与尿液分析结果无关。与非偶然诱因相比,禁欲或有诱因可显着增加治疗期间和随访1年的可卡因禁欲。
