Abstract

Objective : The PTSD Checklist (PCL) is a self-report screen for posttraumatic stress disorder (PTSD) that can be scored for both diagnostic assessment and symptom severity measurement. The most recent revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) contains a number of changes to the definition of PTSD, and the aim of this study was to assess the psychometric properties of the Korean version of the PCL for the DSM-5 (PCL-5-K). Methods : The participants were 204 Korean veterans of the Vietnam War who completed the PCL-5-K, the Mini Mental Status Examination (MMSE), PTSD module of Structured Clinical Interview for DSM-5, Research Version (SCID5-RV PTSD module), Korean version of Impact of Event Scale-Revised (IES-R-K) and Combat Exposure Scale (CES-K). Results : The PCL-5-K demonstrated good internal consistency (${\alpha}=0.972$) and test-retest reliability (r=0.96); the suggested cut-off score for PTSD diagnosis was ${\geq}37$ with 0.88 sensitivity and 0.96 specificity. The PCL-5-K scale correlated highly with the IES-R-K and CES-K. Factor analysis identified only one factor. Conclusion : Among elderly Korean veterans of the Vietnam War, the PCL-5-K demonstrated similar psychometric qualities to those of both the original PCL and subsequent versions. It is expected that the PCL-5-K will be a useful PTSD screening tool.
