초록

This study examined the factor structure and clinical utility of the Korean Childhood Autism Rating Scale, Second Edition-Standard Version (K-CARS2-ST) in young children with neurodevelopmental disorders. Data from 491 children aged 2-6 years, including 211 with autism spectrum disorders (ASD), 143 with communication disorders (CD), and 137 with intellectual developmental disorders (IDD) were analyzed using principal component analysis, covariance analysis, and independent t-tests. The results thus obtained supported a two-factor structure: “Social Communication and Interaction Impairments” and “Restricted, Repetitive Behaviors and Sensory Abnormalities” with internal reliabilities of .82 and .76. The ASD group scored significantly higher than other groups on both total and factor scores. Boys scored higher than girls, and children aged 36 months or older scored higher than younger children only on the “Restricted, Repetitive Behaviors and Sensory Abnormalities” factor. These findings confirm the consistency of the K-CARS2-ST with DSM-5 criteria, supporting its use for early differential diagnosis and intervention planning.
