Background: Validation of post-traumatic stress disorder (PTSD) screening tools across various populations to ensure accurate PTSD estimates is important. Because of the high symptom overlap between PTSD and pain, it is particularly important to validate PTSD screening tools in trauma-exposed chronic pain patients. Objective: The present study is the first seeking to validate the PTSD Checklist for DSM-5 (PCL-5) in a sample of trauma-exposed, treatment-seeking chronic pain patients. Method: The validation and optimal scoring of the PCL-5 were investigated using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) in chronic pain patients exposed to traffic or work-related traumas ( n  = 84). Construct validity was investigated using confirmatory factor analyses testing six competing DSM-5 models in a sample of mixed trauma-exposed chronic pain patients ( n  = 566), and a subsample of chronic pain patients exposed to traffic or work-related trauma only ( n  = 202). Furthermore, concurrent validity and discriminant validity were investigated using correlation analysis. Results: The results showed moderate ( κ  = .46) diagnostic consistency between the PCL-5 and the CAPS-5 using the DSM-5 symptom cluster criteria, and the overall accuracy of the scale (area under the curve = .79) was highly acceptable. Furthermore, the Danish PCL-5 showed excellent construct validity both in the full sample and in the subsample of traffic and work-related accidents, with superior fit of the seven-factor hybrid model. Excellent concurrent validity and discriminant validity were also established in the full sample. Conclusion: The PCL-5 appears to have satisfactory psychometric properties in trauma-exposed, treatment-seeking chronic pain patients.
