Negative cognition in the context of suicidality after exposure to military-related potentially morally injurious events

LAY SUMMARY Moral injury (MI) refers to the psycho-spiritual consequences of events that deeply transgress a person’s core moral beliefs and values. Such events are reportedly common in the military context, and strong associations have been demonstrated between exposure to potentially morally injurious events (PMIEs) and suicidality. This study explored differences in negative cognitions between treatment-seeking Canadian Armed Forces members and Veterans with and without current suicidal thoughts and behaviours (STBs), all of whom reported current distress in response to a PMIE. Those exhibiting STBs reported stronger negative beliefs about the self. Scores for event-related guilt cognitions and self-blame were similar across individuals with and without STBs. Individuals reporting STBs also displayed higher depression and symptoms of posttraumatic stress disorder. The results suggest that severity of mental health symptoms and negative self-evaluations may be most pertinent in their association with suicidality in the MI context. Results remain preliminary, however, and additional research is needed to properly examine how event and self-related evaluations affect suicidality after PMIEs.
