Moral injury symptoms and related problems among service members and Veterans: A network analysis

LAY SUMMARY Both moral injury (MI) and posttraumatic stress disorder (PTSD) can result from adverse experiences (potentially morally injurious events [PMIEs] for the former and Criterion A events for the latter) and may lead to similar symptoms. Thus, debate is ongoing as to whether MI and PTSD are distinct. Depressive symptoms can also follow these events and may also overlap with symptoms of MI and PTSD. This study investigated how distinct MI is from PTSD and depression by examining networks composed of MI-related outcomes (trust violation, shame, functioning), PTSD symptom clusters, and depression for participants who reported experiencing a PMIE and those who did not. This study is the first of its kind to use MI outcomes with PTSD and depression in a network analysis. The results suggest that MI, PTSD, and depression are distinct but related phenomena, with more connections between these phenomena present particularly among those who experienced a PMIE. Moreover, the negative alterations in cognition and mood cluster of PTSD and MI-related functioning appears to explain some of the co-occurrence among constructs.
