Development of Korean Version of PTSD Checklist for DSM-5 (K-PCL-5) and the Short Form (K-PCL-5-S)

초록

Objective This study presents the reliability and validity of the Korean version of the post-traumatic stress disorder (PTSD) checklist for the Diagnostic and Statistical Manual for Mental Disorders-fifth edition (DSM-5) (K-PCL-5) and the short form (K-PCL-5-S). Methods Seventy-one subjects with PTSD, 74 subjects with mood or anxiety disorders, and 99 healthy controls were enrolled. The Ko-rean version of the Structured Clinical Interview for DSM-5-research version was used to confirm the presence of PTSD. The Beck De-pression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), Impact of Event Scale-Revised (IES-R), and Spielberger State Trait Anxi-ety Inventory (STAI) were used to evaluate the concurrent validity of the K-PCL-5 and K-PCL-5-S. Results It presented good internal consistency (Cronbach???s ??=0.93) and test-retest reliability (r=0.90). The K-PCL-5 and K-PCL-5-S were highly correlated with the BDI-II, BAI, IES-R, STAI-S, and STAI-T. The suggested cutoff score for PTSD was 33 for the K-PCL-5 with a sensitivity of 88.51 and specificity of 89.09, and 6 for the K-PCL-5-S with a sensitivity of 91.95 and specificity of 89.09. The data were best explained with a one-factor model. Conclusion These results demonstrated the good reliability and validity of the K-PCL-5 and K-PCL-5-S, and their suitability as simple tools for PTSD assessment.
