The journey to understanding oneself can sometimes lead down unexpected paths, especially when exploring neurodiversity. In recent years, there’s been a growing awareness and acceptance of Autism Spectrum Disorder (ASD) in adults. Many individuals are now seeking to understand if they might be on the spectrum, leading to an increased interest in resources like the Online Autism Test For Adults. Among these tools, the Ritvo Autism Asperger Diagnostic Scale–Revised (RAADS–R) stands out as a self-report questionnaire specifically designed for adults who suspect they might have autism but haven’t received a formal diagnosis.
This article delves into the RAADS-R, offering a comprehensive look at what it is, who it’s for, how it works, and what to consider when using it as part of your self-discovery journey. We’ll explore its strengths and limitations, helping you understand if an online autism test for adults like the RAADS-R could be a helpful first step for you.
What is the RAADS-R?
The Ritvo Autism Asperger Diagnostic Scale–Revised (RAADS–R) is an 80-item self-report questionnaire created to help identify autistic traits in adults. Developed by Riva Ariella Ritvo and her colleagues in 2011, it’s an updated version of the original RAADS, published in 2008. The RAADS-R is designed to be a screening tool for adults, aged 16 and over, with Level 1 ASD or those who believe they might have subclinical autism – individuals who may have “escaped diagnosis” in childhood. It is intended for adults with a normal IQ range (above 80).

Taking the RAADS-R Online: What to Expect
As a self-report instrument, the RAADS-R relies on your own assessment of your experiences. The test is structured around 80 statements that relate to symptoms associated with autism. These symptoms are categorized according to the DSM-5 diagnostic criteria, covering:
- Language: Relating to communication patterns and understanding.
- Social relatedness: Encompassing social interactions and understanding social cues.
- Sensory-motor: Addressing sensory sensitivities and motor skills.
- Circumscribed interests: Focusing on specific, intense interests.
For each of the 80 statements, you’ll be asked to choose from four options that best describe your experience:
- True now and when I was young
- True now only
- True only when I was younger than 16
- Never true
The test typically takes between 10 to 30 minutes to complete, depending on your reading speed and how much time you need to consider each statement.
RAADS-R Subscales Explained
To provide a more detailed picture, the RAADS-R is divided into four subscales, each focusing on specific aspects of autism traits:
Language Subscale
This subscale contains 7 statements focusing on aspects of communication, including:
- Movie talk: The tendency to adopt and frequently use new words or phrases picked up from media.
- Small talk: Difficulty engaging in or understanding the purpose of light, social conversation.
- Literal interpretation: Challenges in understanding nuances in language, sarcasm, or implied meanings.
Social Relatedness Subscale
The largest subscale with 39 statements, this section explores various facets of social interaction and understanding, such as:
- Mentalization: Difficulty understanding the thoughts and feelings of others.
- Mutual interests: Preference for social interactions based on shared, specific interests.
- Feeling like an outsider: A persistent sense of being different or not fitting in socially.
- Bluntness: Being perceived as rude or direct, asking unintentionally embarrassing questions, or pointing out others’ mistakes.
- Dialectical reciprocity: Challenges in turn-taking and knowing when to speak in conversations.
- Emotional reciprocity: Difficulty recognizing social cues like flirting or understanding implied emotions.
- Auditory processing issues: Challenges following conversations with multiple people.
- Object permanence (in social context): Not experiencing a sense of missing people when they are not present.
- Maintaining relationships: Difficulties in forming and keeping friendships.
- Nonverbal communication: Challenges in interpreting body language and facial expressions.
- Mimicry/imitation: Consciously or unconsciously imitating others to fit in socially.
- Camouflaging: Actively masking or hiding autistic traits to appear neurotypical.
Sensory-Motor Subscale
This subscale, with 20 statements, addresses sensory sensitivities and motor skills often associated with autism:
- Voice volume regulation: Difficulties controlling voice volume, speaking too loudly or softly, or fluctuating between volumes.
- Atypical vocal patterns: Speaking in a monotone, childlike, or unusual voice.
- Motor control issues: Clumsiness and lack of coordination.
- Sensory sensitivities: Experiencing sensory input as overwhelming or painful when it’s not bothersome to others, with potential fluctuations in sensitivity.
Circumscribed Interests Subscale
The final subscale with 14 statements, this section focuses on the intense and specific interests often seen in autism:
- Detail-oriented thinking: Focusing on details before grasping the bigger picture.
- Distress from routine changes: Dislike and upset when routines are disrupted by others.
- Special interests: Having and deeply engaging with specific, often narrow, areas of interest.
Scoring and Interpretation: Understanding Your Results
The RAADS-R scoring ranges from 0 to 240. A score of 65 or higher is generally considered indicative of autism, as research has shown that neurotypical individuals typically score below 65. A lower score suggests autism is less likely, but it’s crucial to remember that no online autism test for adults is definitive.
| Construct | Threshold score | Maximum score |
|---|---|---|
| Total score | 65 | 240 |
| Language | 4 | 21 |
| Social relatedness | 31 | 117 |
| Sensory–motor | 16 | 60 |
| Circumscribed interests | 15 | 42 |
It’s important to note that the scoring is reversed for 17 “normative” questions. For most questions, “True now and when I was young” scores 3 points, while for normative questions, “Never true” scores 3 points. These normative questions are designed to assess traits that are typically expected in neurotypical individuals.
Average and Mean Scores
While threshold scores provide a cutoff point, looking at average and mean scores can offer further context. Online RAADS-R data might show higher average scores for neurotypicals due to self-selection bias in online test-takers. Research literature provides more reliable mean scores from controlled studies.
| Total score | Language | Social relatedness | Sensory/ motor | Circumscr. 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 |
| Mean total | Range | Language | Social relatedness | Sensory/ motor | Circumscr. interests | |
|---|---|---|---|---|---|---|
| Autistic spectrum (n = 66) | 133.83 | 44–227 | 11.08 | 67.89 | 32.82 | 28.11 |
| Controls (n = 276) | 25.95 | 0–65 | 1.86 | 9.24 | 5.26 | 5.03 |
Validity and Reliability: How Accurate is the RAADS-R?
The RAADS-R is considered a reliable and valid tool for assisting in the diagnosis of autism in adults. Research indicates strong psychometric properties:
| Measure | Result | Meaning |
|---|---|---|
| Sensitivity | 97% | Test’s ability to correctly identify autistic individuals |
| Specificity | 100% | Test’s ability to correctly identify neurotypical individuals |
| Concurrent validity | 96% | High agreement with other autism assessments like ADOS Module 4 and SRS |
| Test–retest reliability | .987 | Consistent results when the test is taken multiple times by the same person |
A high sensitivity (97%) means the RAADS-R accurately identifies autism in 97% of autistic individuals who take it. A 100% specificity suggests it correctly identifies neurotypical individuals 100% of the time in the study samples. High concurrent validity and test-retest reliability further support its consistency and accuracy as a measure.
Important Considerations Regarding RAADS-R Scores
While a score of 65 or above supports a potential autism diagnosis, it’s crucial to remember that the RAADS-R is a screening tool, not a diagnostic replacement. Clinical judgment and comprehensive assessment are essential for accurate diagnosis. It is also noted that some individuals, particularly younger adults, may not fully recognize or report symptoms that are apparent to clinicians or family members.
Concerns and Considerations: A Balanced Perspective
Despite its validity, experts like Dr. Natalie Engelbrecht raise important points about the RAADS-R. Some concerns include:
- Potentially demeaning statements: Some questions may not accurately reflect autistic experiences and could be perceived negatively.
- Confusion with alexithymia: Certain questions might measure alexithymia (difficulty identifying and describing emotions) rather than autism itself, although alexithymia is often co-occurrent with autism.
- Outdated normative questions: Dr. Engelbrecht suggests that some “normative” questions (statements about expected neurotypical traits) might be based on outdated societal expectations and not reflect the diversity within autism.
Dr. Engelbrecht also points out specific normative statements within the RAADS-R that she finds potentially problematic in their portrayal of autistic individuals, such as suggesting a lack of compassion or dislike of close friendships as definitive autistic traits.
Kendall, another voice in the discussion, highlights that some questions can be difficult to answer accurately, with limited appropriate options, reflecting the nuances of lived experience versus standardized questionnaires.
Conclusion
The online autism test for adults, such as the RAADS-R, can be a valuable initial step for individuals exploring whether they might be on the autism spectrum. The RAADS-R is a well-validated screening tool that can provide insights into autistic traits. A score above the threshold suggests further investigation is warranted.
However, it is vital to recognize that the RAADS-R is not a substitute for a professional diagnosis. If you score high on this online autism test for adults or resonate with the experiences described, seeking a comprehensive evaluation from a qualified clinician is strongly recommended. A professional assessment can provide a nuanced understanding, consider individual context, and lead to appropriate support and resources. Using tools like the RAADS-R responsibly, as part of a broader journey of self-discovery and professional consultation, can be empowering and informative.
