  Abstract: Self-reports of traumatic events are   often used in clinical and epidemiologic studies. Nevertheless,   research suggests combat exposure reports may be biased by   posttraumatic stress disorder (PTSD) symptom severity, leading to   an inflated dose-response relation between combat exposure and   PTSD. The authors examined the consistency in combat exposure   reports and their relation to PTSD symptoms in Vietnam Veteran   American Legionnaires who responded to two mailed surveys (1984,   1998; N = 1,462). Combat exposure reports were highly reliable   (test-retest correlation = 0.87). However, changes in exposure   reporting were related to changes in PTSD symptoms, specifically   reexperiencing symptoms. The effect size of the dose-response   relation attributable to changes in reporting was smaller for   continuous than categorical measures. Findings are discussed in   relation to recent controversies over veterans' combat exposure   reports.
