The Autism-Spectrum Quotient (AQ) children's version has confirmed reliability and validity in the UK. In the current study, the children's AQ was administered in Japan to investigate whether the UK results are found in a very different culture. Two groups of children from primary and secondary schools were assessed: Group 1 (n=81) children with Autism Spectrum Disorders (ASD, including Asperger Syndrome and high-functioning autism); Group 2 (n=372) randomly selected controls, age-matched with Group 1. The children with ASD had a mean AQ score of 31.9 (SD=6.69), which was significantly higher than controls (mean AQ=11.7, SD=5.94). Males scored significantly higher than females in the control group, but not in the ASD group. The pattern of difference between the Japanese clinical group and the control group was remarkably similar to the findings in the UK.
