RAADS-R Test
The RAADS-R is one of the most thorough autism questionnaires for adults: 80 questions that distinguish between "true now", "true only as a child", and "true only now". It was designed for adults whose autism may have been missed earlier in life, including those who have learned to compensate.

Please read each statement and choose the answer that best fits your experiences during social interactions, now and/or when you were younger than 16.
What does the RAADS-R measure?
The Ritvo Autism Asperger Diagnostic Scale-Revised covers four areas: social relatedness, circumscribed interests, language, and sensory-motor experiences. Its distinctive feature is the life-span answer format. Because autism is developmental, symptoms present since childhood carry different weight than ones that appeared later, and the scale scores each answer accordingly, from 0 to 3. Seventeen questions describe non-autistic experiences and are scored in reverse. The total runs from 0 to 240; in the international validation study, a cutoff of 65 separated autistic from non-autistic adults with high accuracy.
What does the result mean?
A score of 65 or above is consistent with autism and worth bringing to a professional assessment, along with the subscale profile. Keep in mind that the RAADS-R was validated in a clinical setting, completed with a clinician present, so an online result carries more uncertainty in both directions. Anxiety, trauma history, and ADHD can push scores up; heavy masking can hold them down. Treat the number as structured evidence for a conversation, not as an answer on its own.
