Frequently Asked Questions

What is the RAADS-R?

The Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R) is an 80-item self-report questionnaire designed to assist in assessing autism spectrum conditions in adults with average or higher intelligence. It covers social interaction, language, sensory-motor, and circumscribed interests.

What RAADS-R score is significant?

In the original validation, adults with autism spectrum conditions averaged around 134, while non-spectrum adults typically scored below 65. The authors suggest a total of 65 as a threshold warranting further clinical assessment.

Can the RAADS-R diagnose autism?

No. It was designed as an adjunct to clinical evaluation, not a replacement. Autism diagnosis requires a qualified clinician considering developmental history and current functioning.

How long does the RAADS-R take?

With 80 statements it usually takes 15-25 minutes. Answer for your adult experiences; items ask how statements applied to you when younger and now.
