Abstract
To determine if diagnostic severity of Autistic Spectrum Disorder (ASD) affected sex differences in the detailed ASD-related behavioural profiles of young males and female, two samples of males and females with a diagnosis of ASD, aged between 6 and 17 years, were compared across the 65 items of the Social Responsiveness Scale (2nd ed.). Results are reported for a sample of males and females matched on age and IQ (n = 51 pairs) and a smaller sample matched on age, IQ and ADOS-2 severity (n = 32 pairs). ASD-related behaviours from the SRS-2 that were significantly and meaningfully different across sexes were identified for both samples. ADOS-2 diagnostic severity was associated with different sets of sex-based differences in SRS-2 item scores.
