Personality traits as predictors of post-traumatic symptoms in conflict zones: the differential roles of neuroticism and extraversion

This study examined how Big Five personality traits influence PTSD symptom development in civilian populations exposed to prolonged, multi-front conflict. Regression analyses of 100 participants revealed substantial increases, yielding three findings challenging conventional trauma models. First, personality traits demonstrated validity: neuroticism amplified PTSD severity while extraversion conferred protection, explaining 21% of variance. Second, contrary to proximity-based frameworks, geographic distance, gender, and military experience showed no effects, suggesting vulnerability transcends conventional demographics. Third, pre-conflict symptoms emerged as the strongest predictor, accounting for 62.5% of variance (R² = 68%). Findings necessitate personality-informed intervention and early identification of vulnerable individuals in conflict-affected populations.
