RAADS-R — Ritvo Autism Asperger Diagnostic Scale–Revised
80-item adult autism screening questionnaire. Provided free by Capstone Mental Health.
Before you start: This is a self-report screening questionnaire, not a diagnostic test.
It cannot diagnose autism on its own. Please answer honestly, based on how you actually are — not how
you think you “should” be. Your answers and results stay on this page in your browser; nothing
is sent anywhere unless you choose to print, save, or email your results yourself.

In the original validation study (Ritvo et al., 2011), a total score of 65 or higher was associated with the range typically seen in autistic adults, while scores below 65 were more typical of non-autistic adults. These informal bands add context but are not separately validated:
| Range | General pattern |
|---|---|
| 0–64 | Below the screening threshold |
| 65–105 | Meets the screening threshold |
| 106–139 | Elevated trait pattern |
| 140+ | Pronounced trait pattern |

This screener is not a diagnosis. Please bring these results to your appointment, or send them to your
clinician, to discuss what they mean for you.
