Abstract
This study aimed to examine the psychometric properties of the Chinese version of the Social Communication Questionnaire SCQ. We assessed 736 participants male, 80.1% aged 2-18, who were clinically diagnosed with autism spectrum disorders ASD including autistic disorder, Aspergers disorder, or pervasive developmental disorders, not otherwise specified according to the DSM-IV diagnostic criteria. All the parents completed the Chinese versions of the SCQ. Among them, parents of 317 participants were interviewed by using the Chinese version of the Autism Diagnostic Interview-Revised ADI-R. The exploratory factor analysis revealed a three- factor structure social interaction, repetitive behaviors, and communication, which was further validated by the confirmatory factor analyses with an adequate fit Goodness-of-Fit Index = 0.923; Comparative Fit Index = 0.983; root mean square error of approximation = 0.034. The test-retest reliability intra- class correlations = 0.77-0.78, internal consistency alpha = 0.73-0.91, and concurrent validity Pearson correlation up to 0.65 were satisfactory. Children with autistic disorder had the highest scores, followed by children with Aspergers disorder who had intermediate scores and then non-ASD participants who had the lowest scores. Our findings suggest that the Chinese SCQ is a reliable and valid instrument for rating autistic symptoms in Chinese-speaking population ClinicalTrials.gov number: NCT00494754. C 2010 Elsevier Ltd.
