ABSTRACT
PURPOSE: Combatants and veterans are at risk of developing post traumatic stress symptoms (PTSS). The long-term responses to traumatic events are variable and can be classified into distinct PTSS trajectories. In this prospective study, we evaluated PTSS trajectories among combat veterans during the initial year after discharge from military service. Subsequently, we analyzed how combat exposure and PMIEs contributed to these trajectories.
METHODS: Our study encompassed 374 combat veterans who participated in a five-year prospective study, with four waves of measurements, T1 – one year before enlistment, T2 – one month prior to discharge from military service (July 2021), and then again at six months (T3 – February 2022) and twelve months after discharge (T4, July-August 2022) .
RESULTS: The utilization of Latent Profile Analysis (LPA) revealed a diverse array of PTSS trajectories. Predominantly, a resilient trajectory emerged as the most frequently observed (69.3%), with ‘delayed onset'(13.6%), ‘improving'(9.9%) and ‘chronic'(6.1%) trajectories following in order. Importantly, multinominal regression analysis indicated that combat exposure and PMIE-betrayal contributed to alignment with symptomatic trajectories.
CONCLUSIONS: This study represents the first of its kind to establish longitudinal, time-dependent associations between PMIEs and PTSS trajectories. These results emphasize the critical importance of ongoing screening and the development of tailored interventions for combat veterans.
