| 摘 要： | The reported prevalence of autism spectrum disorder(ASD) has been increasing rapidly in many parts of the world. However, data on its prevalence in China are largely missing. Here, we assessed the suitability of the modi?ed Chinese version of a newly-developed ASD screening tool, the Modi?ed Chinese Autism Spectrum Rating Scales(MC-ASRS) in screening for ASD in Chi nese children aged 6–12 years, through comparison with the Social Responsiveness Scale(SRS) that has been widely used for ASD screening. We recruited the par ents/caregivers of 1588 typically-developing children and190 children with ASD aged 6–12 years to complete the MC-ASRS and SRS, and evaluated the validity of both scales in discriminating children with ASD from those developing typically. The results showed that MC-ASRSperformed as well as SRS in sensitivity, speci?city, and area-under-the-curve(both [0.95) in receiver operating characteristic analysis, with a fair false-negative rate.These results suggest that MC-ASRS is a promising tool for screening for children with ASD in the general Chinese population.
