Take the free RAADS-R test, a research-validated screening for Autistic traits in adults.
The RAADS-R (Ritvo Autism Asperger Diagnostic Scale-Revised) is a widely used screening tool designed to identify Autistic traits in adults. It was developed by researchers at the UCLA Semel Institute and has been validated in clinical studies.
The test covers four key areas: language, social relatedness, sensory-motor function, and circumscribed interests. It looks at both your current experiences and how you were as a child.
Important: This is a screening tool, not a diagnosis. A high score doesn't confirm you're Autistic, and a low score doesn't rule it out. Use it as a starting point: for your own reflection, or a conversation with a clinician if you decide you want one.
