Brief report: the autism spectrum quotient has convergent validity with the social responsiveness scale in a high-functioning sample

Abstract

The Autism Spectrum Quotient (AQ) is widely used to measure autism spectrum disorder (ASD) symptoms and screen for ASD. It is readily available free of charge online and is easily accessible to practitioners, researchers and individuals who suspect that they may have an ASD. Thus, the AQ is a potentially useful, widely accessible tool for ASD screening. The objective of this study was to examine the convergent validity of the AQ using a well-established, published screening measure of autism: the Social Responsiveness Scale (SRS). Twenty-three high-functioning participants (aged 8-19) with ASD were administered both measures. Results indicated a significant correlation between the SRS and AQ ratings, providing evidence for convergent validity of the AQ with the SRS.
