The 20-year course of posttraumatic stress disorder symptoms among veterans.

ABSTRACT: Although numerous longitudinal studies have examined heterogeneity in posttraumatic stress disorder (PTSD) symptom course, the long-term course of the disorder remains poorly understood. This study sought to understand and predict long-term PTSD symptom course among a nationwide sample of Operations Enduring Freedom and Iraqi Freedom veterans enrolled in Veterans Health Administration services.

Participants (N = 1,353) with and without probable PTSD were sampled at a 3:1 ratio, and male and female veterans were sampled at a 1:1 ratio to fully explore the heterogeneity of PTSD symptom course and the effect of sex on symptom course. By coding time as years since index trauma, we estimated t
