title: Adding voucher-based incentives to community reinforcement approach improves outcomes during treatment for cocaine dependence.
abstract: 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.
