Find answers to common questions about the RAADS-R test, autism assessment, and related topics. This information is based on current research and expert consensus.
The RAADS-R (Ritvo Autism and Asperger Diagnostic Scale-Revised) is a validated self-report questionnaire designed to assess autism traits in adults. It consists of 80 questions that evaluate four key areas:
- Social relatedness
- Circumscribed interests
- Language
- Sensory-motor behaviors
The test was developed by Dr. Riva Ariella Ritvo and colleagues, building upon earlier versions of the scale. It's widely used in research and clinical settings as a screening tool for autism spectrum traits.
The RAADS-R has demonstrated good psychometric properties in research studies:
- High sensitivity (ability to correctly identify those with autism)
- Good specificity (ability to correctly identify those without autism)
- Strong internal consistency
- Good test-retest reliability
However, it's important to note that:
- The test should be used as a screening tool, not a diagnostic instrument
- Results should be interpreted by qualified professionals
- A comprehensive evaluation is necessary for formal diagnosis
The RAADS-R is designed for:
- Adults 18 years and older
- Individuals who suspect they may have autism spectrum traits
- Those seeking to better understand their neurodivergent characteristics
- People considering pursuing a formal diagnosis
The test is not suitable for:
- Children or adolescents
- Individuals with significant cognitive impairments
- Those unable to complete self-report questionnaires
RAADS-R results are interpreted based on total scores and subscale scores:
- Total scores above 65 suggest significant autism traits
- Subscale scores help identify specific areas of strength and challenge
- Results should be considered in context with other factors

The RAADS-R has been extensively researched and validated:
- Multiple peer-reviewed studies support its reliability and validity
- Research has demonstrated good discriminant validity between autistic and non-autistic individuals
- Studies have shown good concurrent validity with other autism assessment tools

After taking the RAADS-R test, consider these next steps:
- Review your results carefully and read the interpretation guide
- Consider discussing your results with a qualified healthcare professional
- Explore our Resources page for additional information and support
- Connect with autism support communities and organizations
Remember that the RAADS-R is just one tool in understanding autism traits. A comprehensive evaluation by qualified professionals is necessary for formal diagnosis.
