I scored 26 even with being an introvert.
I think this test will give a false negative for having an ASD in some cases. I don't like it.
Extroverts will score artificially low as will people who are imaginative or have an intuitive/analytical thinking style. Not all aspes are introverts and not all aspies enjoy concrete factual information.
Personally I detest categories and rote memorization. I'm more of a theorist. I'm extremely lazy when it comes to remembering facts and quoting sources. I enjoy inferring things and looking for broader patterns and implications. I always want to understand the larger picture, how everything fits together. Most NT's are more black-and-white / concrete than I am. I go against the aspie stereotype of being literal minded, concrete, and full of facts/trivia. I'm the polar opposite. Pointless detail and trivia annoy me.
Yes, it's not going to be totally accurate for everyone, especially when you scored a 26 (which you still scored high compared to how the population does). However, quite a few studies have found that it's good as a casual screening process, not all the detailed diagnostic work.
If found this study really interesting:
S. Baron-Cohen, S. Wheelwright, R. Skinner, J. Martin and E. Clubley, (2001) The Autism Spectrum Quotient (AQ) : Evidence from Asperger Syndrome/High Functioning Autism, Males and Females, Scientists and Mathematicians Journal of Autism and Developmental Disorders 31:5-17
They gave it to a random selection group of diagnosed Asperger's/HFA, a random selection group of non-diagnosed subjects (control group), and a random selection group of students from university. 80% of all the diagnosed Asperger's/HFA scored 32+ and the mean for them was about 36. Only 2% of the control group scored above 32. So, to me it sounds like it can give false negatives, but not so much in false positives.
I looked at the studies charts and there were a couple of the diagnosed Asperger's/HFA who scored in the high teens or lower twenties, although more rare. Most of them scored 26 or above, then once it got to the 30's it shot up.
It made me think because they also gave the test to Math Olympiad subjects and math students at the university, and they only scored in the lower 20's, so it would seem like there's more to Autistic-like traits than just nerd-like. It seems like the test is not perfect, but from testing it would seem like a good rough estimate, especially in not giving a false positive if you score high.
So to test the AQ test for myself, I decided to see how people in this forum score. I also want to go to some other forms and ask people randomly to take it, just so I can see how they do. I was thinking of finding an OCD forum to see if it can differentiate them from Asperger's/HFA, since there is the repetitive nature. It may be that many diagnosed with OCD may also be Autistic Spectrum.
Here are some of the studies I found on this test:
