CM Treatment for Alcohol Dependence Using New Technology

Study Overview
=================
Brief Summary
-----------------
Contingency management (CM) is highly efficacious for reducing substance use, and recent data suggest that reinforcing attendance at treatment can significantly improve treatment outcomes. Importantly, CM interventions that reinforce attendance are more likely to be adopted clinically than those that reinforce abstinence. Having objective indicators of drinking outcomes, nevertheless, is critical for quantifying the benefits of attendance-based CM treatment in alcohol abusing populations. New technology is now available to gauge alcohol use in patients' natural environments. The Secure Continuous Remote Alcohol Monitor (SCRAMx®) continuously monitors alcohol consumption 24 hours a day. As such, it may be ideal for objective evaluation of alcohol consumption during treatment intervention studies, including those that involve CM. In this study, 114 patients participating in community based outpatient treatment programs for alcohol use disorders will wear SCRAMx for a 12-week period. They will be randomized to standard care or standard care plus CM, with reinforcement contingent upon attendance at treatment. The investigators will assess treatment attendance and alcohol use via SCRAMx and self reports. The investigators expect that patients randomized to the CM intervention will remain in treatment longer and show reductions in both SCRAMx assessed and self reported drinking days relative to those randomized to standard care.
