Desarrollo de una versión breve de la PTSD Checklist (PCL) basada en la definición de trastorno de estrés postraumático de la CIE-11

Introduction and objectives: The main objective of the present study was to develop, from the PTSD Checklist (PCL), a self-report measure of posttraumatic stress symptoms based on the ICD-11 symptomatic criteria for posttraumatic stress disorder (PTSD). Material and methods: Seven PCL items were selected to develop the PCL-ICD-11, and its psychometric properties were analyzed in a sample of 634 victims of terrorism who completed the specific version of the PCL (PCL-S) along with a structured diagnostic interview and measures of depression and anxiety. Results: The results indicate that the PCL-ICD-11 shows a unifactorial structure with good fit indices that is replicated in two subsamples of victims created randomly from the global sample. The PCL-ICD-11 shows excellent indices of internal consistency (α > .85) and very good indices of diagnostic validity to identify PTSD (AUC > .90 and kappa ≥ .75), discriminates significantly and with large effect sizes (d = 0.88
