The Prevalence of Post-Traumatic Stress Disorder Symptoms in Chronic Pain Patients in a Tertiary Care Setting: A Cross-Sectional Study.

Controlled studies have only examined specific patient populations, such as those with motor vehicle accidents, war veterans, work-related injuries, back pain, and headache.

Objective: The purpose of this study was to estimate the prevalence of PTSD symptoms in patients with chronic pain at a large multidisciplinary pain clinic.
