Summary

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.

Interventions

Type	Name	Description
BEHAVIORAL	Group Brief Alcohol Intervention	The BAI contained components of effective interventions developed for young adult drinkers both in health care and educational settings and was specifically tailored to the unique needs and risk factors of Airmen. The 1-hour group intervention was administered using the principles of motivational interviewing (MI) in an interactive Socratic style to generate feedback and discussion. Open-ended questions, reflections, as well as the decisional balance scale were used to increase Airmen's motivation to remain alcohol free.
BEHAVIORAL	Group Brief Alcohol Intervention Booster	The 1-hour booster intervention was delivered using MI to extend the effective elements found in the original BAI intervention with elements from behavioral economic theory. A behavioral economic approach to alcohol use suggests that decisions to drink are more likely when 1) there is a lack of access to or engagement in alternative alcohol-free reinforcing activities, and 2) there is a greater relative focus on immediate, relative to delayed, rewards (i.e., steep delayed reward discounting). The intent of the intervention is to bring important long-term goals into the present so that the immediate awareness of this goal might diminish the relative benefit of drinking. Another goal was to have the Airmen identify enjoyable and goal-consistent alcohol-free activities they could engage in during their free time. The booster also included a reminder of the U.S. Air Forces rules and policies on alcohol use and harm reduction drinking strategies.
BEHAVIORAL	Bystander Intervention	The 1-hour Bystander intervention was a non-alcohol related briefing that served as the control condition. The intervention focused on increasing Airmen's awareness of the qualities of being a good "wingman" (e.g., watching for their peers) and how those are tied to the Air Force Core Values. It aimed to increase participants' perceived responsibility to act in certain situations. The intervention draws on the philosophy that members in a community have a role in shifting social norms to prevent violence (Coker et al., 2011). While the intervention did not directly discuss alcohol use, the focus on military values and taking responsibility for one's self and others could contribute to healthier drinking-related choices.
