A prospective investigation of protective factors for moral injury and psychiatric symptomatology among Israeli combatants: A Latent Class Analysis approach

Abstract: In this prospective study, we examined pre-enlistment characteristics and pre-deployment protective factors of exposure to potentially morally injurious events (PMIEs) among Israeli active-duty combatants, as well as psychiatric symptomatology outcomes of exposure. 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: 6 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 (T2-T3) between 2019 and 2021. Latent Class Analysis (LCA) was used to identify three classes characterized by unique patterns of exposure to PMIEs (T2): Minimal Exposure (56.6%), Betrayal-Only (25.5%), and High Exposure (17.8%). Higher levels of pre-deployment psychological flexibility (T1) were associated with higher odds for inclusion in the high exposure class (T2). As compared to the minimal exposure class, both high exposure and betrayal-only classes were associated with higher levels of mental health symptoms and MI-related psychological outcomes (T2). This is the first prospective study of antecedents and outcomes of exposure to PMIEs among active-duty combatants. Clinicians treating combatants should be aware of the different types of exposure to PMIEs and their possible psychiatric outcomes.
