An Autism-Spectrum Quotient Questionnarie


Located at Wired the article uses a Psychometric test published by Psychologist Simon Baron-Cohen and his colleagues back in 2001.

I figured it was going to be interesting to see what my result was after answering the 50 questions.

Quite honestly, it was a bit of a surprise that my Autism-Spectrum Quotient wasn’t higher, even just slightly — even more surprising was that I scored higher than my girlfriend (<3)!

During the initial trials of the questionnaire, the average score in the control group was 16.4. Men tended to score slightly higher (about 17) than women (about 15).

The authors caution that the questionnaire it is not intended to be diagnostic. Anyone who obtains a high score and is suffering some distress should seek professional medical advice before jumping to any conclusions; after all — 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.

Of the adults diagnosed with autism spectrum disorders who took the test, 80% of them scored 32 or more. In comparison, only 2% of the control group score as high, or higher.

If you’re wondering, further research indicated that the questionnaire could be used for screening in clinical practice. Scores less than 26 indicating that a diagnosis of Asperger syndrome can effectively be ruled out.

Woodbury-Smith MR, Robinson J, Wheelwright S, Baron-Cohen S (2005). Screening adults for Asperger Syndrome using the AQ: a preliminary study of its diagnostic validity in clinical practice (PDF).

How to score: “Definitely agree” or “Slightly agree” responses to questions 2, 4, 5, 6, 7, 9, 12, 13, 16, 18, 19, 20, 21, 22, 23, 26, 33, 35, 39, 41, 42, 43, 45, 46 score 1 point.
