Voucher-based reinforcement for alcohol abstinence using the ethyl-glucuronide alcohol biomarker

J Appl Behav Anal. Spring 2012;45(1):161-5. doi: 10.1901/jaba.2012.45-161.


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.
