About RAADS-R

RAADS-R (Ritvo Autism Asperger Diagnostic Scale – Revised) is a self-report screening questionnaire designed to assist in the identification of autistic traits in adults, particularly in individuals whose autism may not have been recognized in childhood. In clinical contexts, it may be used as part of a broader assessment. This instrument alone does not establish a diagnosis.

What does my score mean?

Remember: RAADS-R is not a diagnosis but a screening tool.

Summary:
You have a low likelihood of clinically relevant autistic traits and likely no indication for a formal assessment. Your autism screening result is negative.

Summary:
You are above the formal cutoff of 65 points for autism screening. You likely have autistic traits, but possibly not enough for a formal diagnosis.

Summary:
You are above the 65-point cutoff for autism screening. Autism is more likely unless factors such as substance use (e.g., alcohol or cannabis) or medical conditions (e.g., anemia or hypothyroidism) better explain your score.

Summary:
Your score is comfortably within a range often seen in autistic adults with higher independence. Without significant substance use (e.g., alcohol or cannabis) or medical conditions (e.g., severe anemia or long-standing hypothyroidism), a formal diagnosis is likely.

Summary:
Your score is within an average range often reported by autistic adults. A diagnosis appears likely, even if other health or lifestyle factors are also present.

Summary:
Your score aligns with the average pattern of responses from autistic adults. Even with other health or lifestyle factors, autism is very likely.

Summary:
Your scores are high—above the average range of autistic responses. Even other health or lifestyle factors do not invalidate the likelihood of an autism diagnosis.
