US Army Drill Sergeants: Stressors, Behavioral Health, and Mitigating Factors.

Introduction: The role of the drill sergeant is one of the most challenging within the US Army, involving unusually long hours and little time off, for a minimum of 2 years. The current study sought to examine the behavioral health of this population and identify risk factors that might be addressed by policy changes.

Materials And Methods: In total, 856 drill sergeants across all Army basic training sites completed surveys from September to November of 2018. Drill sergeants identified factors that had caused stress or worry during their assignment. Rates were measured for behavioral health outcomes including depression, insomnia, anxiety, burnout, functional impairment, alcohol misuse, aggression, and low morale. Potential risk and resilience factors included time as a drill sergeant, sleep, route of assignment, general leadership, health-promoting leadership, and drill sergeant camaraderie. The study was approved by the Walter Reed Army Institute of Research Institutional Review Board.

Results: The most commonly experienced stressors were finding time to exercise, lack of sleep, and long work hours. Percentages of drill sergeants meeting behavioral health screening criteria were 19% for depression, 27% for moderate-to-severe insomnia, 14% for generalized anxiety disorder, 48% for high burnout, 32% for functional impairment, 35% for moderate alcohol misuse, 32% for off-duty aggression, and 25% for low morale. Rates for most outcomes were associated with time spent as a drill sergeant, with behavioral health issues peaking during 13-18 months. Poorer outcomes were also associated with fewer hours of sleep and initial unhappiness regarding involuntary assignment to the role of drill sergeant, while better outcomes were associated with higher ratings of general leadership, health-promoting leadership, and drill sergeant camaraderie.

Conclusions: This study is the first to examine behavioral health and morale of drill sergeants and to identify risk and resilience factors. Suggestions for policy changes include increasing the number of drill sergeants to decrease workload and allow sufficient time for recovery and sleep.
