Psychologist Simon Baron-Cohen and his colleagues at Cambridge’s Autism Research Centre have created the Autism-Spectrum Quotient, or AQ, as a measure of the extent of autistic traits in adults. In the first major trial using the test, the average score in the control group was 16.4. Eighty percent of those diagnosed with autism or a related disorder scored 32 or higher.
The test is not a means for making a diagnosis, however, and many who score above 32 and even meet the diagnostic criteria for mild autism or Asperger’s report no difficulty functioning in their everyday lives.
UPDATE: Due to the age of the code powering the calculation required for the test it no longer works. We are coding a more modern version that will be available shortly. Manual calculation of the score is available by following the instructions at the bottom of the test.
