What is the Autism Spectrum Quotient (AQ)? 

The Autism Spectrum Quotient (AQ) is a self-report questionnaire designed to measure the presence of autistic traits in adults with a normal IQ. The AQ consists of 50 questions related to social interaction, communication and social imagination along with attention to detail and attention switching. The AQ aims to provide an insight into the extent of autistic traits an individual has.














How are AQ scores interpreted?

  • A score of 26 or higher may indicate a presence of autism

  • A score of 25 or below may indicate an absence of autism

  • Almost 80% of autistic individuals score 32 or above

  • The majority of non-autistic individuals score between 15-17 on average

  • It is important to note that the AQ is only a screening instrument to help with the assessment process and an accurate diagnosis of autism can only be made by a qualified specialist
