Abstract

OBJECTIVES
We examined the agreement between the Autism Diagnostic Observation Schedule (ADOS) and the Childhood Autism Rating Scale (CARS) in the diagnosis of autism spectrum disorder.
METHODS
The ADOS and CARS scores of 78 children were retrospectively collected from a chart review. A correlation analysis was performed to examine the concurrent validity between the two measures. Using the receiver operating characteristic (ROC) curve, we determined the optimal cut-off score of the CARS for identifying autism spectrum disorder.
RESULTS
The CARS score was significantly correlated with the ADOS score (r=0.808, p < 0.001). Taking ADOS as the ideal standard, the optimal cut-off scores of CARS for identifying autism and autism spectrum were 30 and 24.5, respectively.
CONCLUSION
We determined the optimal cut-off scores of CARS for screening and diagnosing autism spectrum disorder.
