The association of resilience on psychiatric, substance use, and physical health outcomes in combat trauma-exposed military service members and veterans

Abstract

ABSTRACT Objective: Although Combat exposure is associated with a range of psychiatric outcomes, many veterans do not develop psychopathology. Resilience is a multifaceted construct associated with reduced risk of distress and psychopathology; however, few studies have examined the relationship of resilience with a broader spectrum of health outcomes following combat exposure. It also remains important to determine the association of resilience above and beyond other documented risk and protective factors. Method: In a sample of combat-exposed veterans (N = 1,046) deployed to Iraq and Afghanistan, we examined a quantitative method for exploring relative psychological resilience (discrepancy-based psychiatric resilience; DBPR) and tested the hypothesis that resilience would be associated with reduced risk for psychiatric diagnosis count, substance use, and physical health outcomes, above and beyond other known correlates (e.g. combat exposure, social support). Results: In the final model, results suggested an inverse association of discrepancy-based psychiatric resilience with current psychiatric diagnosis count (β = −0.57, p < .001), alcohol use (β = −0.16, p < .001), drug use (β = −0.13, p < .001), and physical health concerns (β = −0.42, p < .001) after accounting for other relevant risk and protective factors. Conclusions: Results extend the nomological net of this quantitative resilience construct to include other relevant health outcomes, and demonstrate that resilience may have more of a buffering relationship with psychiatric and physical health concerns compared to substance use outcomes.
