The Autism Spectrum Quotient (AQ) Test is a self-report questionnaire designed to measure the degree of autistic traits in adults. It was developed by Simon Baron-Cohen and his colleagues at the Autism Research Centre at the University of Cambridge. The test consists of fifty questions which measure five areas of autistic symptomatology (social skills, communication, imagination, attention to detail, and attention switching). The results of the AQ test are intended to provide an indication of the level of autistic traits in an individual and can help to identify those who may benefit from further assessment.
