When American psychiatrists updated their diagnostic manual in 2013, they acknowledged a difficulty with IQ tests and autism. The adult repetitive behaviours questionnaire-2 (RBQ-2A): A self-report measure of restricted and repetitive behaviours. The autism-spectrum quotient (AQ): Evidence from Asperger syndrome/high-functioning autism, males and females, scientists and mathematicians. (The lower the scores, the better.) Score Distributions.
