    Abstract:
    A Simplified Chinese translation of the Autism Spectrum Quotient-Children's Version (AQ-C) is needed for research in mainland China. Autism Spectrum Disorder (ASD) is a condition that differs in presentation and prevalence by sex. Thus, evaluating the psychometric validity of the AQ-C in males and females is an important step in its validation. The present study aims to develop a Chinese translation of the parent-report AQ-C, and test its psychometric properties among Mandarin Chinese speaking boys and girls. A total of 1,020 non-clinical children and 134 children with ASD were assessed. Factor analyses were performed for the whole sample, as well as for girls and boys separately. A 30-item, 5-factor model (the Chinese AQ-C) showed adequate goodness of fit (root mean square error of approximation [RMSEA] = 0.037; comparative fit index [CFI] = 0.907; Tucker-Lewis index [TLI] = 0.901) for the whole sample. According to parents' reports, non-clinical boys had significantly higher scores than non-clinical girls on the Chinese AQ-C. Sex-specific factor structures were identified resulting in a 4-factor model with 32 items for girls (the Chinese AQ-Girls), and a 4-factor model with 34 items for boys (the Chinese AQ-Boys). The cut-off scores of the Chinese AQ-C, AQ-Girls, and AQ-Boys were 44.5, 42.5, and 46.5, respectively. These three Chinese versions of the AQ-C all showed satisfactory internal consistency (α = 0.786-0.840) and concurrent validity with the Social Responsiveness Scale (r = 0.789-0.814) for the total scale. Differences have been found in the sex-specific factor structures of the AQ-C which would be more reliable to use for future research when measuring autistic traits in the general population.

LAY SUMMARY: This study developed Chinese versions of the Autism Spectrum Quotient-Children's Version (AQ-C) in Chinese boys and girls together and separately. The AQ-C showed good psychometric properties in boys and girls together and separately. There were differences in sex-specific factor structures of the AQ-C. These results suggest that the sex-specific Chinese versions of the AQ-C provide reliable and valid measurement of autistic traits.
