Prevention of Alcohol Related Incidents in the US Air Force

Alcohol misuse poses significant public health concerns in the U.S. military. A Brief Alcohol Intervention (BAI) have been shown to reduce alcohol related incidents among Airmen undergoing training. The current study sought to examine whether a booster BAI administered at the end of an Airmen's training reduced alcohol related incidents out to a one-year follow-up. Participants were 26,231 US Air Force Technical Trainees recruited between March 2016 and July 2018. Participants were cluster randomized by cohort to two conditions: BAI + BAI Booster or BAI + Bystander Intervention. The primary analysis was a comparison of the interventions' efficacies in preventing Article 15 alcohol related incidents at a one-year follow-up, conducted using a generalized estimating equations logistic regression model controlling for covariates.
