Many Risk Factors for Post-Traumatic Stress Symptomatology among OEF/OIF Veterans have Pre-Deployment Origins


BACKGROUND:
The mental health condition most commonly associated with trauma exposure is PTSD, and there is a large body of literature aimed at exploring the psychosocial risk factors for PTSD. Prior research on risk factors for post-traumatic stress symptomatology (PTSS) in war-exposed Veterans has revealed both direct and indirect mechanisms of risk that span pre-deployment, deployment, and post-deployment timeframes. This study sought to identify the mechanisms through which previously documented risk factors (among Vietnam Veterans) contribute to PTSS in a national sample of female (n = 333) and male (n = 246) OEF/OIF Veterans exposed to combat operations who had returned from deployment in the 12 months preceding the study. Using mailed, self-reported survey data, investigators assessed several factors, including: warfare exposure (e.g., firing a weapon, being fired upon, witnessing injury or death); aftermath of battle (e.g., exposure to human remains); relationship disruptions, childhood family functioning (e.g., family cohesion), and post-deployment support (e.g., emotional support from family and friends). Gender differences were examined for all variables.

FINDINGS:

  • Post-traumatic stress symptomatology (PTSS) appears to be accounted for by multiple chains of risk, many of which originate in pre-deployment experiences (e.g., history of trauma, troubled family backgrounds) that put both female and male OEF/OIF Veterans at risk for additional stress exposure. Moreover, earlier experiences of stress may lead to the depletion of resources over time, as well as greater risk of subsequent stress exposure.
  • The majority of previously documented risk pathways in Vietnam Veterans held for both women (88%) and men (75%) in this sample of OEF/OIF Veterans, providing support for the generalizability of mechanisms of risk for PTSS across Veteran populations.
  • Relationship concerns during deployment increased risk for PTSS, especially among female Veterans. Female Veterans who reported more concerns about relationship disruptions during deployment also reported less post-deployment social support.
  • Warfare exposure had a direct effect on PTSS, suggesting that those who experience high levels of objective events of combat, even those who don’t report experiencing high levels of threat or fear, appear to be at risk for PTSS.
  • Female OEF/OIF Veterans reported lower levels of warfare exposure and relationship concerns than male OEF/OIF Veterans. No significant differences were found between men and women for childhood family functioning, prior stressors, perceived threat, post-deployment stressors, post-deployment social support, or PTSS.

LIMITATIONS:

  • Direct comparisons between men and women in this study were not possible.
  • This study relied on retrospective self-reported data.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
