Are autistic traits measured equivalently in individuals with and without an autism spectrum disorder? An invariance analysis of the Autism Spectrum Quotient Short Form.
Self-perception in high-functioning children and adolescents with Autism Spectrum Disorder (ASD) was examined by comparing parent- and self-reports on the Autism Spectrum, Empathy, and Systemizing Quotients (AQ, EQ and SQ). Participants were 20 youths with ASD and 22 typically developing controls. Both parents and participants in the ASD group reported more autistic traits (higher AQ) and less empathy (lower EQ) than the control group. SQ ratings did not differ between groups. Comparisons of self- and parent-reports indicated that youths with ASD reported significantly fewer autistic traits and more empathic features than their parents attributed to them. There were no discrepancies between parent- and self-reports in the control group. Implications regarding the use of self-report in ASD are discussed.
