Background Early autism screening is of great value,but there is lack of a screening tool of early age (2-5 years) in China.The Autism Spectrum Rating Scale (ASRS,2-5 years) is a newly developed autism screening tool in the USA.This study aimed to evaluate the reliability and validity of the translated Chinese version of ASRS (C_ASRS) in Chinese children population before its application in China for early autism screening.Methods Caregivers of general children aged 2-5 years from 17 kindergartens and autism spectrum disorder (ASD) cases from five special education schools in five cities were recruited to complete the C_ASRS.1910 valid questionnaires from kindergarteners and 192 from ASD cases were included for analyses.Results The item reliability (Cronbach's alpha) was more than 0.80 in the screening scale and DSM-5 scale,and 0.51-0.81 in the treatment scale.ASD cases scored higher on total score and most subscales compared to the kindergarteners (Cohen's d ranging from 1.34 to 3.37).C_ASRS showed good discriminatory validity with an area under the receiver operating characteristic curve of 0.850 (95% confidence interval:0.819-0.881).The cutoff ≥ 60 achieved sensitivity of 65.63% and specificity of 85.63% in discriminating autism children from the general population.Conclusion The results indicate that C_ASRS (2-5 years) could be used as an early level-2 screening tool for autism screening in China and should be further revised for level-1 screening.
