Ritvo Autism Asperger Diagnostic Scale – Revised (RAADS-R)

The Ritvo Autism Asperger Diagnostic Scale – Revised (RAADS-R) is a self-report psychological assessment designed to measure autism spectrum-related traits in adults. The scale evaluates areas such as social interaction, communication style, emotional understanding, sensory sensitivity, routines, repetitive behaviors, and thinking patterns that are commonly associated with autism spectrum conditions.

The RAADS-R was developed to help identify autistic traits in adults who may not have been recognized or diagnosed during childhood. Many individuals with autism spectrum characteristics learn to hide or adapt their difficulties over time, which can make identification more challenging in adulthood. The assessment focuses on lifelong patterns of behavior and experiences rather than temporary emotional states.

The scale examines several important areas including social communication difficulties, sensory processing differences, restricted interests, repetitive behaviors, emotional interpretation, conversational style, and preference for routines or sameness. Higher scores may indicate stronger autism-related characteristics affecting social functioning, communication, adaptability, sensory experiences, and daily interactions.

The assessment consists of 80 statements and typically takes 15–25 minutes to complete. Participants respond to statements describing lifelong social experiences, communication styles, sensory sensitivities, behavioral patterns, interests, routines, and developmental characteristics commonly associated with autism spectrum conditions.

This assessment is intended for adults and older adolescents interested in understanding autism spectrum-related characteristics. Participation in this online RAADS-R test is completely anonymous. No personally identifying information is collected or stored.

The RAADS-R consists of 80 items scored using a four-point developmental response format designed to distinguish between current and lifelong autism spectrum-related characteristics.

Response options are weighted according to the original RAADS-R scoring system:

• True now and when I was young = 3 points
• True only now = 2 points
• True only when I was younger than 16 = 1 point
• Never true = 0 points

Certain items are reverse-scored according to the original RAADS-R scoring guidelines.

Total RAADS-R Score ranging from 0 to 240.

Results include a Total RAADS-R Score and scores for four domains:

• Social Relatedness
• Circumscribed Interests
• Language
• Sensory-Motor

For reporting purposes, domain scores are converted to a standardized 0–100 scale to facilitate comparison across domains.

Traditionally, a total score of 65 or higher has been considered a threshold associated with clinically significant autism spectrum-related traits in research settings.
