Moral Injury and Resilience in Military Personnel: An Integrative Review

Military service exposes personnel not only to life threat but also to events that violate deeply held moral beliefs, such as killing, failing to prevent harm, or being betrayed by trusted leaders. The psychological aftermath of such events has been termed moral injury, a construct that overlaps with, but is distinct from, posttraumatic stress disorder (PTSD). In parallel, military organizations have invested heavily in resilience programs intended to protect service members from adverse psychological outcomes. This integrative review synthesizes conceptual, epidemiological, and intervention research on moral injury and resilience in military populations. Evidence indicates that potentially morally injurious events are common among combat veterans, that exposure is associated with PTSD, depression, and suicidality independent of fear-based trauma, and that guilt, shame, and loss of trust are central mechanisms. Resilience, defined as a stable trajectory of healthy functioning after adversity, is the modal response to deployment, yet most resilience training targets fear and stress appraisals rather than moral meaning. We propose an integrative model in which individual, social, and organizational resources moderate the pathway from morally injurious events to moral injury, and outline implications for assessment, training, leadership, and treatment. We conclude that resilience programming should be expanded to include moral preparation and organizational accountability, and that rigorous longitudinal and intervention research is needed.
