  • Title: Personality traits as moderators of the associations between deployment experiences and PTSD symptoms in OEF/OIF service members.
    Author: Caska CM, Renshaw KD.
    Journal: Anxiety Stress Coping; 2013; 26(1):36-51. PubMed ID: 22129461.
    Abstract:
    This investigation examined traits from the five-factor model of personality as moderators of the associations of combat and aftermath of battle experiences with symptoms of posttraumatic stress disorder (PTSD) in 214 National Guard/Reserve service members deployed to operations enduring and Iraqi freedom. Extraversion significantly moderated the associations of both combat experiences and aftermath of battle experiences with PTSD severity, with associations weakening as levels of extraversion increased. The relation between aftermath of battle experiences and PTSD was also moderated by the other four personality factors, with the relation being weaker at higher levels of agreeableness, conscientiousness, and openness, and lower levels of neuroticism. These results suggest that personality traits may impact individual responses to war trauma, particularly war-related experiences that are not directly threatening to one's safety (i.e., aftermath of battle events vs. actual combat events). Although this investigation was cross-sectional, these findings indicate that personality traits are an important risk/resiliency factor to consider in people's responses to traumatic events.
