Comparing the Psychometric Properties of the Self- and Parent-Report Versions of Autism-Spectrum Quotient-Adult in Hong Kong (AQ-Adult-HK)
The Autism-Spectrum Quotient-Adult (AQ-Adult) is a screening tool for adults with autism spectrum disorder (ASD). The present study examined the psychometric properties of the Chinese self- and parent-report versions of the AQ-Adult in Hong Kong (AQ-Adult-HK). Participants included adults with ASD (n = 27) and community controls (n = 345). Parents of a subset of adults with ASD (n = 21) and controls (n = 87) also participated as informants. The parent-report version showed significantly stronger psychometric properties, including a larger area under receiver operating characteristic curve (AUC) and higher sensitivity/specificity, than those of the self-report version. The stronger psychometric properties of the former were related to its significantly higher ratings of ASD symptoms in the ASD adults.
