Widening the scope: defining and treating moral injury in diverse populations

Moral injury is an emerging concept that captures the psychosocial consequences of involvement in and exposure to morally transgressive events. In the past decade, research on moral injury has grown exponentially. In this special collection we review papers on moral injury published in the European Journal of Psychotraumatology from its inception until December 2022, that have a primary focus on moral injury as evidenced by the words ‘moral injury’ in the title or abstract. We included 19 papers on quantitative (n = 9) and qualitative (n = 5) studies of different populations including (former) military personnel (n = 9), healthcare workers (n = 4) and refugees (n = 2). Most papers (n = 15) focused on the occurrence of potentially morally injurious experiences (PMIEs), moral injury and associated factors, while four papers primarily concerned treatment. Together, the papers offer a fascinating overview of aspects of moral injury in different populations. Research is clearly widening from military personnel to other populations such as healthcare workers and refugees. Focal points included the impact of PMIEs involving children, the association of PMIEs and personal childhood victimisation, the prevalence of betrayal trauma, and the relationship between moral injury and empathy. As for treatment, points of interest included new treatment initiatives as well as findings that PMIE exposure does not impede help-seeking behaviour and response to PTSD treatment. We further discuss the wide range of phenomena that fall under moral injury definitions, the limited diversity of the moral injury literature, and the clinical utility of the moral injury construct. From conceptualisation to clinical utility and treatment, the concept of moral injury matures. Whether or not moral injury becomes a formal diagnosis, the need to examine tailored interventions to alleviate moral injury is clear.
