Primary use / Purpose: 

The AQ is designed to measure the degree to which an individual possesses symptoms typical of the autistic spectrum. It is a 50 item measure, while the AQ-10 is a ten item condensed version.


The Autism Spectrum Quotient (AQ) was developed due to a need for brief self-administered instruments to determine an individual’s position on the autism-normality continuum.


Psychometrics are discussed in Baron-Cohen, Wheelwright, Skinner, Martin and Clubley (2001).
