The aim of this project was to review the literature in relation to how moral injury is conceptualised, models of moral injury, linkages between moral injury and common mental health issues, and the effectiveness of moral injury interventions in veteran and military populations.

In order to answer these questions, a narrative literature review and a REA were conducted.

Military personnel are often confronted with situations whereby under extreme conditions, they make decisions, take action or exposed to events that challenge their ethical and moral beliefs. Transgressions of ethical and moral beliefs and inner conflict can arise from such circumstances and lead to potential mental health problems. The aim of this Rapid Evidence Assessment (REA) was to examine the evidence and efficacy of interventions targeting moral injury in military personnel and veterans. Psychological and interdisciplinary therapies that may be appropriate in targeting symptoms associated with moral injury were identified and assessed for their effectiveness in treating moral injury.
