Key methodological aspects and major findings of reviewed studies on Moral Injury and Post-Traumatic Stress Disorder in Military Population

Steps to reproduce

Specifically, we explored and summarized the published literature to examine the co-occurrence of MI and PTSD in military personnel and evaluated the published studies to better understand the association between MI and PTSD, together with other emotional distress. For this purpose, the study applied parallel literature searches in Scopus, PsycINFO, ResearchGate and Web of Science using the key terms “moral” and “injury”, “PTSD”, “traumatic stress”, “stress disorder”, “acute stress”, combined with terms relating to “military”, “combatants”, “veterans”, “active on duty”. These databases were selected based on their significant coverage of psychological and philosophical literature as well as accessibility for the researchers. The study extracted only articles, and books chapters. Additional inclusion criteria included that the studies assessed the association between MI and PTSD, were empirical research studies with reliable and valid results, and recruited participants from military personnel. After searching in these database, we compared the identified list of articles with the results of another literature search in Research4Life, an initiative which provides institutions in lower income countries with online access to academic and professional peer-reviewed content as a way to improve teaching, research and policymaking in health and other life, physical and social sciences. An initial review and selection protocol assessed the biases of each study and identified the appropriateness and quality of the available evidence.
