If you have wondered if you have autism, or autistic traits, this brief test may be a useful screening tool to provide you with some basic insight to help you in discussions with medical professionals about getting an official diagnosis.   This questionnaire was first published in 2001 by Simon Baron-Cohen and his colleagues at the Cambridge Autism Research Centre as part of a study entitled The Autism Spectrum Quotient (AQ): Evidence from Asperger syndrome/high-functioning autism, males and females, scientists and mathematicians.
