The authors studied 492 children aged 6-18 years who had been diagnosed with ASD at the New York University Child Study Centre. They then used the Child Behaviour Checklist (CBCL) to assess gender related issues and looked at the relationship between the two. They found that subjects with ASD were 7.76 times more likely to report gender variance than the rest of the sample. They conclude that ‘The present study is a large-scale retrospective prevalence study that confirms a heightened level of co-occurrence of ASD and GV. It joins a growing body of literature that consistently supports such co-occurrence’.
