Longitudinal associations between transgressions of moral beliefs and suicidal ideation among recently discharged veterans

We evaluated longitudinal associations between subjective appraisals of transgressions of moral beliefs, values, and expectations (potential morally injurious events; PMIEs) and suicidal ideation (SI) among recently discharged combat veterans. Participants were 374 active-duty Israeli combatants who participated in a five-year longitudinal study with four measurement points: T1- one year before enlistment, T2- one month before discharge from army service, and then again six months and twelve months following discharge (T3 and T4, respectively). A history of lifetime suicidal ideation and behavior was associated with higher levels of subjective appraisals of PMIEs, as compared to no history of suicidal ideation and behavior. Above and beyond pre-enlistment personal characteristics, cross-lagged pathway analyses indicated significant bi-directional pathways between subjective appraisals of PMIEs and SI. For all PMIEs dimensions, SI was associated with greater subjective appraisals of PMIEs, on subsequent measurement. However, cross-lagged effects of PMIEs-‘other’ (T2) predicting SI (T3) and PMIEs-‘betrayal’ (T3) predicting SI (T4) were also found. Our findings are the first to provide evidence of longitudinal, temporal associations between subjective appraisals of PMIEs and SI, which might serve as potential intervention targets among recently discharged traumatized veterans.
