This study compares the efficacy of the Community Reinforcement Approach (CRA) with and without an incentive program for cocaine-dependent patients in Spain. A total of 58 patients were randomly assigned to the CRA or CRA plus vouchers condition. In the CRA plus vouchers group, mean percentage of cocaine-negative samples was 97.07%, versus 79.76% in the no-voucher group. Those treated in the CRA plus vouchers condition also achieved greater improvements in psychosocial functioning than those treated in the CRA condition. The present results show that treatment outcome is better if incentives are delivered contingent upon the submission of cocaine-free urine specimens.
本研究比较了社区强化治疗（CRA）联合和不联合奖励方案对西班牙可卡因依赖患者的疗效。共有 58 名患者被随机分配到 CRA 或 CRA 加优惠券组。在 CRA 加优惠券组中，可卡因阴性样本的平均百分比为 97.07%，而无优惠券组为 79.76%。在 CRA 加优惠券组中，治疗的患者在心理社会功能方面的改善也优于在 CRA 组中治疗的患者。目前的结果表明，如果根据提交的可卡因尿液样本给予奖励，治疗效果会更好。
