= .878), and similar associations with improvements in measures of depression and psychosocial functioning. However, the two measures did not produce identical estimates of symptom change. Estimates of symptom improvement were somewhat less concordant at posttreatment follow-up assessments; by the 12-month posttreatment assessment, changes in CAPS-5 scores from baseline indicated somewhat greater symptom improvement than changes in PCL-5 scores (CAPS-5 ESsg = -0.67, PCL-5 ESsg = -0.53). Collectively, results indicate that CAPS-5 and PCL-5 scores produce similar but not identical estimates of PTSD symptom change. Thus, although PCL-5 scores closely approximate symptom change estimated by CAPS-5 scores, the two measures are not interchangeable. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
