Abstract

The Symptom Checklist - Post-Traumatic Stress Disorder Scale (SCL-PTSD), also known as Crime-Related PTSD Scale has been validated in survivors of interpersonal trauma in the general population. However, the psychometric properties have not been investigated in a clinical setting for patients with PTSD from diverse traumatic events. This study investigates the reliability and validity of the Korean version of the SCL-PTSD among 104 psychiatric outpatients with PTSD, caused by interpersonal (n = 50) or non-interpersonal trauma (n = 54). Self-report data of the SCL-PTSD, Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and Impact of Events Scale-Revised (IES-R) were gathered. The Korean version of the SCL-PTSD showed excellent internal consistency and moderate-togood four-week temporal stability in both the interpersonal and non-interpersonal trauma groups. In comparison with other diagnostic groups, the scores of the SCL-PTSD were significantly higher compared to those of adjustment disorder, depression, other anxiety disorders, and schizophrenia, demonstrating its criteria-related validity. Convergent validity was confirmed because the scores of the SCL-PTSD were significantly correlated with BDI, SAI and TAI scores. Concurrent validity was demonstrated by significant correlation with the IES-R score. This study demonstrated the favorable psychometric prosperities of the Korean version of the SCL-PTSD, supporting its use in clinical research and practice.
