RESUMEN
Moral injury, an experience of betrayal or transgression of moral values, continues to receive attention because of its associations with psychiatric disorders, including posttraumatic stress disorder and suicidality. There is growing recognition that moral injury may require novel interventions that involve religious or spiritual paradigms. This pilot study presents feasibility data and exploratory outcomes for 40 veteran participants across seven cohorts who participated in a novel 12-week moral injury group (MIG) over 35 months. The MIG was cofacilitated by a Veterans Affairs chaplain and psychologist and designed to reduce distress and improve functioning in individuals with histories of morally injurious experiences from military service. The intervention included a ceremony in which participants shared testimonies of their moral injury with the general public. Recruitment feasibility and retention were high, with participants completing an average of 9.45 (SD = 2.82) sessions of the 12-week group, and 32 participants (80.0%) attending nine or more sessions and the community healing ceremony. Exploratory analyses revealed medium effect sizes, ω2 = 0.05-0.08, for reductions in depressive symptoms, improvements in psychological functioning, and self-compassion after the intervention, with small effect sizes, ω2 = 0.03, in anticipated directions for personal growth and spiritual struggles. The results were not impacted by participant engagement in concurrent psychological treatments. Taken together, these findings support the feasibility of the MIG, the potential merit of an interdisciplinary approach to addressing moral injury, and justification for further research into the efficacy of this approach.
