Objectives: Alcohol use in the U.S. military is prevalent and associated with alcohol-related incidents (ARIs), an official U.S. Air Force sanction. Military ARIs incur substantial personal and financial costs. We evaluated the impact of the Alcohol Misconduct Prevention Program (AMPP) consisting of a group-based brief alcohol intervention (BAI) conducted jointly with random alcohol breathalyzer testing on ARIs in the U.S. Air Force. Methods: A 1-hour, group-based, interactive BAI was conducted, and random alcohol breathalyzer testing was performed among 10,087 Air Force Technical Trainees at Lackland Air Force Base in San Antonio, Texas, in fiscal years 2010 and 2011. Results: The AMPP was associated with a significant reduction in the odds of an ARI over the year of the intervention compared to the previous year (odds ratio 0.555; 95% confidence interval 0.380-0.811; p = 0.0023). Significant reductions in the number of ARIs were observed within all quarters except for the third. The average rate of ARIs per 1,000 trainees per quarter was 7.30 before implementation of the interventions and 4.06 after implementation. Conclusion: An AMPP consisting of an interactive BAI and random alcohol breathalyzer testing may decrease ARIs among military trainees.
