The purpose of this study was to explore the psychometric properties of the Chinese version of the autism spectrum rating scale(ASRS). We recruited 1,625community-based children and 211 autism spectrum disorder(ASD) cases from 4 sites, and the parents of all participants completed the Chinese version of the ASRS. A robust weighted least squares means and variance adjusted estimator was used for exploratory factor analysis. The3-factor structure included 59 items suitable for the current sample. The item reliability for the modi?ed Chinese version of the ASRS(MC-ASRS) was excellent. Moreover,with 60 as the cut-off point, receiver operating characteristic analysis showed that the MC-ASRS had excellent discriminate validity, comparable to that of the unmodi?ed Chinese version(UC-ASRS), with area under the curve values of 0.952(95% CI: 0.936–0.967) and 0.948(95% CI:0.930–0.965), respectively. Meanwhile, the con?rm factor analysis revealed that MC-ASRS had a better construct validity than UC-ASRS based on the above factor solution in another children sample. In conclusion, the MC-ASRS shows better ef?cacy in epidemiological screening for ASD in Chinese children.
