IntroductionResearchers and practitioners are invested in understanding how deployment experiences impact the nearly 193,000 U.S. service members who deploy in a given year. Yet, there remains a need to adequately identify salient deployment experiences through survey measurement tools and understand how differential experiences are uniquely related to mental health outcomes. Therefore, this study examined the factor structure of an established combat experiences measure from the Army Study to Assess Risk and Resilience in Service members (Army STARRS) dataset to identify underlying survey constructs that reflect nuanced deployment experiences. Then, we examined the association between diverse combat experiences and current mental health symptoms (i.e., anxiety and depressive symptoms) and the mediating role of coping.Materials And MethodsData were drawn from the Army STARRS data (N = 14,860 soldiers), specifically the All Army Study component. A principal component analysis (PCA) was conducted to examine the dimensionality of the combat experiences scale, and then a path model was conducted to examine the relationships between combat experiences, coping with stress following a deployment, and mental health symptoms while controlling for relevant individual and interpersonal factors.ResultsResults from the principal component analysis suggested that the Army STARRS combat experiences scale encompasses two components, specifically: "Expected combat experiences" and "Responsible for non-enemy deaths." Both "Expected combat experiences" and "Responsible for non-enemy deaths" were associated with higher levels of anxiety and depressive symptoms, respectively, and "Responsible for non-enemy deaths" was also indirectly linked to these mental health outcomes through coping with stress after deployment.ConclusionsThese findings provide insight into the dimensionality of combat experiences and offer practitioners a more nuanced understanding of how to process unique combat experiences that differentially relate to mental health symptoms.© The Association of Military Surgeons of the United States 2021.
