Reliable and clinically significant change in the clinician-administered PTSD Scale for DSM-5 and PTSD Checklist for DSM-5 among male veterans.

ABSTRACT: We calculated the reliable change index (RCI) and clinically significant change (CSC) values for two widely used measures of posttraumatic stress disorder (PTSD): The Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) and the PTSD Checklist for DSM-5 (PCL-5) and examined how symptom changes at these thresholds related to improvements in psychosocial functioning.

For Sample 1, within-person change in CAPS-5 and PCL-5 scores of ≥ 13 and 15, respectively, was indicative of reliable change. For Sample 2, within-person change i
