The Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) is a structured interview that assesses the frequency and severity of each symptom of posttraumatic stress disorder (PTSD) in relation to a single traumatic stressor over a 1-month period, allowing the trained interviewer to infer a current or lifetime diagnosis congruent with the 5th Edition of the Diagnostic and Statistical Manual of the American Psychiatric Association. This study evaluated the psychometric properties of the original English language CAPS-5 translated to French. Participants (N = 168) were recruited in clinical settings of France, Lebanon, and Canada. The psychometric properties of the measure were found to be excellent, as good-to-strong interitem consistency was found (α = .90; ITC = .52; ICC = .30), while also finding strong convergent validity between the CAPS-5 total score and the severity score of a self-report PTSD measure (r = .82): the PCL-5. The test-retest reliability was excellent, with Cohen's κ = 1.00 and the intraclass coefficient (ICC) = .95. However, no latent factor structure model was deemed a strong fit to the data. Overall, the reliability and validity of the French CAPS-5 and are consistent with those of the original CAPS-5. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
