The autism quotient has been developed by using the commonly known diagnosis criteria of autism. These criteria have a male autism bias because of the way that Aspergers/HFA was initially studied. To offer a clearer indication for women you can use the chameleon quotient. This has been developed to specifically calculate female traits, which have been researched by Tania Marshall. Tania Marshall has defined 10 areas that women with autism display their traits and this is the research that has been used to create this self-diagnostic tool.
The Chameleon Quotient has 50 questions, all with multiple-choice answers (definitely agree, slightly agree, slightly disagree and strongly agree), there are 5 questions for each area that Tania Marshall suggests that females differ in autism.
A score of 35 or above gives an indication of female autism.
