Abstract

Objective The purpose of this study was to examine the validity and reliability of the Korean Comprehensive Scale for the Assessment of Challenging Behavior in Developmental Disorders (K-CSCB). Methods In total, the parents of 189 patients with autism spectrum disorder (ASD) and 168 controls completed the K-CSCB, the Behavior Problems Inventory (BPI) and Child Behavior Checklist (CBCL). The reliability and validity of the K-CSCB was investigated. Results The K-CSCB was found to be a reliable instrument (Cronbach’s α=0.97). There was a significant difference between the ASD and control groups in all subscale scores. Scores on the K-CSCB subscales were significantly correlated with those on the BPI and CBCL. The diagnostic validity was 97.7%, and the cut-off score with the highest sensitivity and specificity was 12.5 points. Conclusion The K-CSCB is the first tool in Korean to assess problematic behavior in individuals with ASD, and this study shows that it is a valid and reliable instrument. We expect the K-CSCB to be widely used in clinical and research settings.
