Basic Questions About RAADS-R

What is the RAADS-R test?

The RAADS-R is a self-report questionnaire designed to help identify autism spectrum traits in adults. It consists of 80 questions that evaluate four key areas: social relatedness, language, sensory-motor function, and circumscribed interests. This test was developed by Dr. Ritvo and colleagues and has been validated through extensive research [^1].

Who should take the RAADS-R test?

The test is specifically designed for:

  • Adults aged 16 and above

  • People with average or above-average intelligence (IQ ≥80)

  • Individuals who suspect they might have autism traits but haven't received a formal diagnosis

  • Those referred by healthcare providers for autism evaluation

How long does the test take?

Most people complete the RAADS-R in 20-30 minutes, though there's no strict time limit. It's more important to answer thoughtfully than quickly.

Scoring and Results

What do RAADS-R scores mean?

The total scores range from 0 to 240. Here's a general interpretation:

  • 0-25: Few or no autistic traits detected

  • 26-64: Some autistic traits present

  • 65-130: Significant autistic traits present

  • 131-160: Strong indication of autism

  • 161-190: Very strong indication of autism

  • 191-240: Extremely strong indication of autism

What's considered a "significant" score?

A score of 65 or higher is considered significant and may indicate the presence of autism traits. In research studies, no non-autistic participants scored above 64 [^2].

Technical Aspects

How is the test structured?

The RAADS-R evaluates four main areas:

  1. Social Relatedness (39 questions)

  2. Language (7 questions)

  3. Sensory-Motor (20 questions)

  4. Circumscribed Interests (14 questions)

How accurate is the RAADS-R?

Research shows the RAADS-R has:

  • 97% sensitivity (ability to identify autism)

  • 100% specificity (ability to identify non-autism)

  • High test-retest reliability (.987)

Important Considerations

Can the RAADS-R diagnose autism?

No, the RAADS-R is a screening tool, not a diagnostic instrument. While it can indicate the presence of autism traits, only qualified healthcare professionals can provide an official diagnosis through comprehensive evaluation.

Should I take the test multiple times?

While you can take the test multiple times, it's designed to have high test-retest reliability. If you choose to retake it, wait a significant period and answer based on your genuine experiences rather than trying to achieve a specific score.

What should I do after taking the test?

If you score 65 or higher:

  1. Consider consulting with a healthcare professional

  2. Document your experiences and challenges

  3. Consider taking other validated autism assessments

  4. Discuss the results with your healthcare provider
