RAADS-R Score Distribution Analysis
This graph shows the distribution of RAADS-R test scores based on the original validation study (Ritvo et al., 2011) involving 477 participants. The data demonstrates clear differentiation between autistic and non-autistic score patterns.
Note: This distribution is based on research data from the original validation study published in the Journal of Autism and Developmental Disorders (Ritvo et al., 2011, DOI: 10.1007/s10803-010-1133-5). Individual results may vary, and scores should always be interpreted by qualified healthcare professionals. The threshold score of 65 was established based on this distribution pattern, where no non-autistic participants scored above this value in the study of 477 participants (201 ASD and 276 comparisons).

- True only now (1 point)
- True only when I was younger than 16 (2 points)
- Never true (3 points)
Important Note About RAADS-R Scores
Remember that the RAADS-R test is just one tool in understanding autism traits. A high score suggests you might benefit from a professional evaluation, while a low score doesn't necessarily rule out autism. Always consult with qualified healthcare professionals for a proper diagnosis.
Frequently Asked Questions About RAADS-R Test
The RAADS-R (Ritvo Autism Asperger Diagnostic Scale-Revised) is a professionally validated screening tool designed to assist in identifying autism spectrum traits in adults. It consists of 80 questions across four domains: social relatedness, language, sensory-motor, and circumscribed interests. The test was developed by Dr. Ritvo and colleagues and published in the Journal of Autism and Developmental Disorders in 2011.
For more detailed information, please consult with healthcare professionals.
RAADS-R Test Subscales Explained
Language (7 Questions)
The language subscale evaluates how you use and understand language in social situations:
- Movie Talk: Friends notice you've heard something new because you start using the word or phrase regularly
- Small Talk: Light conversations about everyday topics that people make during social interactions
- Being Literal: Understanding when spoken words don't match their intended meaning
Social Relatedness (39 Questions)
This largest subscale examines how you interact with and understand others:
Sensory-Motor (20 Questions)
This subscale looks at how you experience physical sensations and movement:
- Speaking volume control in different situations
- Speaking patterns (monotone, childlike, or using silly voices)
- Physical coordination and movement skills
- Reactions to sounds, textures, lights, and other sensations that might not bother others
Circumscribed Interests (14 Questions)
This subscale explores your patterns of interests and routines:
- Focusing on details while still seeing the bigger picture
- Reacting to unexpected changes in your routines
- Having and discussing specific intense interests
RAADS-R Test Average Scores Explained
The table below shows typical RAADS-R scores across different groups, helping you understand how your results compare to others:
| Group | Total Score | Language | Social Relatedness | Sensory/Motor | Circumscribed Interests |
|---|---|---|---|---|---|
| Autism Threshold Values | 65.0 | 4.0 | 31.0 | 16.0 | 15.0 |
| Autistic Males | 148.6 | 11.9 | 71.3 | 36.7 | 28.7 |
| Autistic Females | 160.4 | 12.8 | 73.5 | 43.1 | 31.0 |
| Suspected Autistic Males | 141.6 | 11.2 | 70.0 | 33.3 | 27.2 |
| Suspected Autistic Females | 145.2 | 11.3 | 67.2 | 38.7 | 28.0 |
| Neurotypical Males | 84.2 | 6.6 | 43.0 | 19.0 | 15.7 |
| Neurotypical Females | 91.6 | 6.8 | 42.8 | 24.8 | 17.2 |
Understanding the Scores
You might notice that some neurotypical scores are above the autism threshold (65). This is because the online test data includes people who thought they were neurotypical but scored in the autistic range. Research with confirmed neurotypical participants shows much lower average scores.
Research-Based Mean Scores
For more accurate comparison, here are the mean scores from clinical research studies:
| Group | Mean Total | Range | Language | Social Relatedness | Sensory/Motor | Circumscribed Interests |
|---|---|---|---|---|---|---|
| Autistic Spectrum (n=66) | 133.83 | 44-227 | 11.08 | 67.89 | 32.82 | 28.11 |
| Asperger (n=135) | — | — | 10.06 | 65.07 | 28.96 | 27.44 |
| Controls (n=276) | 25.95 | 0-65 | 1.86 | 9.24 | 5.26 | 5.03 |
RAADS-R Test Validity and Reliability
The RAADS-R is a scientifically validated instrument for assisting in the diagnosis of autism in adults. Here's what research tells us about its accuracy:
- No neurotypical who took the test scored above the autism threshold
- Only 3% of the autistic group did not score over 65
- Test-retest reliability was particularly high for the autistic group
| Measure | Result | What This Means |
|---|---|---|
| Sensitivity | 97% | Test's ability to identify positive results |
| Specificity | 100% | Test's ability to identify negative results |
| Concurrent Validity | 96% | Test's validity compared with ADOS Module 4, SRS |
| Test-retest Reliability | .987 | Test's agreement between results of successive measurements |
Understanding Sensitivity
A sensitivity of 97% means that 97% of autistic people who took the test met the cutoff score and were accurately classified as autistic. This represents the proportion of autistic individuals who were correctly identified by the test.
Understanding Specificity
The 100% specificity score means that all neurotypical people who took the test were correctly classified as non-autistic. This perfect specificity indicates the test's strong ability to avoid false positive results.
Important Clinical Considerations
A RAADS-R score of 65 or higher supports an autism diagnosis, but a clinician's diagnosis should take precedence if there are differences. Some symptoms may only become apparent during a professional interview.
Research shows that some autistic individuals, especially those in their late teens and early twenties, may not recognize symptoms that are apparent to their families and clinicians.
Latest Research Findings (2024)
Recent studies show that age, gender, and self-perception of autism don't affect how people understand and respond to the RAADS-R test. The only factor that significantly influences responses is the person's actual neurotype. Diagnosed and self-identified autistic individuals tend to respond similarly, while those uncertain about their status show different response patterns.
