Mereish EH, et al. - Researchers undertook a daily dairy study of daily alcohol use among heavy drinking sexual minority men to determine the conditions under which daily stressful and positive events are associated with alcohol use among heavy drinking sexual minority men (SMM). The moderating effects of two indicators of alcohol addiction severity (i.e., alcohol dependence severity and negative drinking consequences) on the associations between daily stressful events and alcohol use and between daily positive events and alcohol use among heavy drinking SMM were specifically examined. Observations reveal that stressful and positive events were both associated with daily drinking. Addiction severity was observed moderating the associations between these events and drinking.
