This study holds the promise of establishing an efficacious intervention approach for Type 2 diabetic patients who are at-risk drinkers and are likely to maintain poor diabetes treatment adherence and outcomes in the absence of a change in their drinking behavior, resulting in increased diabetes-related morbidity and mortality. The intervention proposed in this study represents a novel approach to reducing at-risk drinking among diabetic patients that, if efficacious, can be readily integrated into the treatment of diabetes in a variety of treatment settings. In addition, this study will provide valuable information regarding the relationship between alcohol use and diabetes treatment adherence and outcomes and about the mechanisms of change in alcohol use among Type 2 diabetic patients who are at-risk drinkers.
