Autism-Spectrum Quotient (AQ)

Background

The Autism Spectrum Quotient (AQ-50) is a self-report screening questionnaire developed to measure autistic traits in adolescents and adults with average or above-average intelligence. The scale was created by Simon Baron-Cohen and colleagues at the Autism Research Centre, University of Cambridge.

The AQ-50 measures characteristics commonly associated with autism spectrum conditions across social interaction, communication, imagination, attention switching, and attention to detail. It is widely used in psychological research, educational settings, and mental health screening.

This assessment is intended for screening and educational purposes only and does not provide a clinical diagnosis.

Procedure

You will read a series of statements related to social behavior, communication, imagination, routines, and attention patterns. Select the response that best describes how strongly you agree or disagree with each statement based on your everyday experiences.

Participation

There are no right or wrong answers. Respond honestly and choose the option that best reflects your typical behavior, preferences, and experiences.

Scoring & Interpretation

The AQ-50 uses a trait-based scoring system designed to measure the degree of autism-related characteristics. Higher scores may indicate stronger autistic traits involving social interaction, communication style, attention patterns, routines, and imagination.

This assessment is a screening tool only and should not be used as a substitute for professional clinical evaluation.
