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. We assessed PTSD symptoms at 4 time points over approximately 4.5 years (M = 55.11 months, SD = 6.89). 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 the course of PTSD symptoms over 20 years. Results indicate symptom course is most appropriately characterized by substantial heterogeneity. On average, veterans experienced initial PTSD symptom severity above the diagnostic threshold following trauma exposure, which was initially stable over time and later began to gradually improve. Although results indicate symptoms eventually began to decline, this effect was gradual; most participants continued to meet or exceed the PTSD provisional diagnostic threshold long after trauma exposure. We identified several predictors and correlates of symptom course, including Hispanic ethnicity, postdeployment social support, and co-occurring psychopathology. Results highlight the heterogeneous nature of PTSD symptom course following trauma exposure and the urgency of the need to ensure access to evidence-based care and to improve available treatments.
