The current study tested the effectiveness of using National Alcohol Screening Day (NASD) to deliver personalized feedback via mail. At-risk NASD participants were assigned to either personalized or generic feedback conditions and attended a 4-week follow-up. Results failed to find any group differences on alcohol-related variables. However, participants in the personalized group reported a reduction in the maximum number of drinks consumed on one occasion. The personalized group also had a more accurate view of the amount of alcohol their peers consumed. NASD is a vehicle to efficiently deliver feedback to individuals about their alcohol use; however, more research is needed to determine the types of feedback that would be most effective.
