[Reliability and Validity of the Abridged Chinese Version of Autism Spectrum Quotient-Child form in China].

OBJECTIVE: To determine the reliability and validity of the abridged Chinese version of the autism spectrum quotient (AQ) -child form. METHODS: A total of 86 children with autism spectrum disorder (ASD) were recruited from the West China Hospital from July 2014 to December 2016, along with 6 896 children recruited from three schools in Chengdu. The participants completed the AQ scale under instructions from a trained interviewer. Then 170 school children were selected and repeated the AQ scale within one month. RESULTS: All subscale scores were correlated with the scale score, but with weak inter-subscale correlations. The total AQ score of the control group was continuously distributed in the population, which was similar to the normal distribution. The skewness was -0.127 and the kurtosis was -0.124, indicating that the total AQ score was negatively skewed and slightly flat in the population.There were differences in AQ scores between different genders in community children (P 0.05) . The sensitivity and specificity of AQ for screening ASD was both 0. 71. CONCLUSION: The abridged Chinese version of the AQ-child scale has good psychometrics properties and may be a valid and reliable instrument for ASD screening with a cut-off score of 48.
