The purpose of the present study was to develop and evaluate a scale to measure adaptive behavior skills in Chinese children with autism spectrum disorder (ASD). Participants were 121 young children (M = 55.18 months, SD = 0.18 months) with a formal diagnosis of ASD (73% male). Psychometric evaluation indicated that the reliability and validity of this scale were good. Furthermore, independent t-tests revealed that boys demonstrated better adaptive behavior skills than girls. The present findings suggest that the scale is a valid measure of adaptive behavior skills in Chinese children with ASD.
