The Relationship Between Self-Disclosure and Symptoms of Posttraumatic Stress Disorder in Peacekeepers Deployed to Somalia

The challenges of peacekeeping place individuals at risk for the development of significant psychological distress (e.g., B. T. Litz, S. Orsillo, M. Freidman, P. Ehlich, & A. Batres, 1997). Self-disclosure has been shown to ameliorate psychological distress following exposure to potentially traumatic events (J. W. Pennebaker & K. D. Harber, 1993). Sharing, or self-disclosure of deployment-related experiences, was the focus of this study and was hypothesized to be associated with adaptation. As part of a larger investigation, 426 U.S. military personnel who served as peacekeepers in Somalia were administered a comprehensive psychosocial questionnaire that included measures of exposure to negative and potentially traumatic experiences, reception at homecoming, self-disclosure, and PTSD symptom severity. The results indicate that adjustment to peacekeeping is significantly related to self-disclosure, especially to supportive significant others.
