Took some time to find an English one (had a dutch one here, same questions)
Here goes:
Wired 9.12: Take The AQ Test
This is actually a pretty serious test.
It's used as an intake-test for people of whom they expect some autism disorder.
If you score anything above 24, it's suspicious
.
If you score anything above 32, you have a 80% rate of indeed having an autistic disorder.
This, of course, is based on people taking this test and then lots of tests after that.
Pretty much everyone who's tested for autism gets this test in the Netherlands.
It's actually developed by the cousin of Sacha Baron-Cohen (Yes, Ali G.). ;D.
Another interesting thing: There's a lot of autists on my own forum.
And I discovered this very strange thing: Everyone who scored 33 on the test, is actually a close friend of mine. There's also people who scored lower who are close friends of mine, but seven people scored 33 and all seven of them were friends. About 100 people did that test. I scored 33 myself, too, by the way.
