Autism-Spectrum Quotient (AQ)

What is autism spectrum disorder (ASD)?

Autism spectrum disorder (ASD) is a neurodevelopmental condition that affects how people communicate, process sensory information, and interact socially. It’s associated with differences in social communication and with restricted or repetitive patterns of behavior and interests.

Many autistic people have difficulty navigating social situations—for example, reading nonverbal cues, keeping a back-and-forth conversation going, or understanding unspoken social rules. The level of support a person needs can vary widely.

Many autistic people also have areas of strong focus or deep interest. In some cases, these strengths can translate into high achievement in specific domains.

In the United States, ASD is estimated to affect about 1% of people.

Autism-Spectrum Quotient (AQ)

In 2001, Simon Baron-Cohen and colleagues at the Autism Research Centre, University of Cambridge developed the Autism-Spectrum Quotient (AQ) to assess autistic traits. The AQ measures how strongly traits associated with ASD are expressed. Research suggests the full 50-item questionnaire is generally more valid and reliable than the brief 10-item version, so we offer the full AQ-50 here.

FAQ

Does a high score on the test indicate autism?

No, a high score only indicates the presence of significant autistic traits. Autism is a complex condition that requires a comprehensive evaluation by a specialist for an official diagnosis.

How does the AQ differ from other autism tests (e.g., RAADS-R)?

The AQ test focuses on five areas: social skills, attention switching, attention to detail, communication, and imagination. The RAADS-R is often considered a more in-depth tool for identifying "hidden" autism in adults, but the AQ remains the "gold standard" for initial screening.

Can test results change over time?

Autistic traits are generally stable throughout life. However, results may fluctuate slightly depending on your current emotional state, stress levels, or growing self-awareness.
