description: <b>Background:</b> Combatants who are exposed to events that transgress deeply held moral beliefs might face lasting psychopathological outcomes, referred to as Moral Injury (MI). However, knowledge about pre-deployment factors that might moderate the negative consequences of MI is sparse. In this prospective study, we examined pre-enlistment characteristics and pre-deployment personality factors as possible moderators in the link between exposure to potentially morally injurious events (PMIEs) and psychiatric symptomatology among Israeli active-duty combatants. <b>Methods:</b> A sample of 335 active-duty Israeli combatants participated in a 2.5-year prospective study with three waves of measurements (T1: 12 months before enlistment, T2: Six months following enlistment – pre-deployment, and T3: 18 months following enlistment – post-deployment). Participants’ characteristics were assessed via semi-structured interviews (T1) and validated self-report measures of personality factors: emotional regulation, impulsivity, and aggression (T2) and combat exposure, PMIEs, psychiatric symptomology and posttraumatic symptoms (T3) between 2019 and 2021. <b>Results:</b> Pre-enlistment psychiatric difficulties and negative life events contributed to higher exposure to PMIEs post-deployment. Higher levels of pre-deployment aggression and lower levels of emotional regulation and impulsivity moderated the association between betrayal, PMIEs and psychiatric symptomology post-deployment, above and beyond pre-enlistment psychiatric difficulties and life events. <b>Conclusions:</b> Our results highlight that pre-deployment emotional regulation, impulsivity and aggressiveness levels should be assessed, screened, and identified among combatants, as they all facilitate psychiatric symptomology (and PTSS) after combatants are exposed to PMIEs of betrayal. Such pre-assessment will enable the identification of at-risk combatants and might provide them with tailor-made preparation regarding moral and ethical situations that should be investigated in future research. Pre-enlistment psychiatric difficulties contributed to higher exposure to PMIEs post-deployment.Pre-deployment personality moderated the associations between PMIEs and psychiatric symptomatology among combatants.Higher levels of pre-deployment emotional regulation moderated the association between betrayal PMIEs and post-deployment PTSS symptoms. Pre-enlistment psychiatric difficulties contributed to higher exposure to PMIEs post-deployment. Pre-deployment personality moderated the associations between PMIEs and psychiatric symptomatology among combatants. Higher levels of pre-deployment emotional regulation moderated the association between betrayal PMIEs and post-deployment PTSS symptoms.
