Comprehensive Autism Self-Assessment
80 questions across four domains. Designed specifically for adults who were not diagnosed in childhood. Takes 20 to 30 minutes.
The RAADS-R (Ritvo Autism Asperger Diagnostic Scale-Revised) was developed by Ritvo et al. (2011) to identify autism in adults who "escaped diagnosis" as children. It is one of the most comprehensive self-report autism measures available.
Each question asks about a behavior or experience across two time periods: now and when you were young (before age 16). A total score of 65 or above indicates likely autism. The mean score for autistic adults in the validation study was 133; for non-autistic adults, 44.
Answer honestly based on your own experience, not what you think the "right" answer is. There are no right or wrong responses.

The RAADS-R was validated with 201 autistic adults and 578 non-autistic comparison subjects. It has a sensitivity of 97% and specificity of 100% at the threshold of 65. No non-autistic participant in the validation study scored above 65.
The four domains measure distinct aspects of the autistic experience. Elevated scores on Social Relatedness and Sensory-Motor domains are the most common pattern. Language scores tend to be lower on average. Circumscribed Interests captures intense, focused engagement with specific topics.
