Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R)
The Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R) is a tool used to assist the diagnosis of autism spectrum disorders in adults. It's designed to measure the presence and severity of autism-related symptoms. This self-test provides a preliminary measure and is not intended as a diagnostic tool.

| 90 | Enhanced signs of autism, though scores this high can also be found in non-autistic individuals. |
| 130 | Average score among individuals with autism, indicating a strong likelihood of autism. |
| 160 | Overwhelming evidence pointing towards autism. |
| 227 | Highest score recorded by individuals with autism in the foundational RAADS-R study by Ritvo. |
| 240 | The absolute maximum score attainable on the RAADS-R scale. |
Important Precaution
This test is a self-assessment tool and not a definitive diagnostic instrument. The results should be used as a reference and not as a final diagnosis. Autism spectrum disorders can only be diagnosed by qualified professionals. If your results indicate the possibility of an autism spectrum disorder, or if you have concerns about your mental well-being, please seek guidance from a medical professional or specialist.
