This study assessed the effects of a contingency management (CM) intervention for alcohol consumption in 10 alcohol-dependent participants. An ABCA design was used. Vouchers were provided contingent on results of ethyl glucuronide (EtG) urine tests (an alcohol biomarker with a 2-day detection period) and alcohol breath tests during the C phase. The percentage of negative urines was 35% during the first baseline phase, 69% during the C phase, and 20% during the return-to-baseline phase. Results suggest that EtG urine tests may be a feasible method to deliver CM to promote alcohol abstinence.
本研究评估了一项针对 10 名酒精依赖参与者的基于条件的管理（CM）干预对饮酒行为的影响。采用 ABCA 设计。在 C 阶段，根据乙基葡萄糖醛酸（EtG）尿液检测（具有 2 天检测期的酒精生物标志物）和酒精呼气测试的结果提供代金券。在第一个基线阶段，阴性尿液的百分比为 35%，在 C 阶段为 69%，在返回基线阶段为 20%。结果表明，EtG 尿液检测可能是一种可行的方法，可通过提供 CM 来促进酒精戒除。
