What the RAADS-R measures (Ritvo Autism Asperger Diagnostic Scale–Revised)
The Ritvo Autism Asperger Diagnostic Scale-Revised is a widely recognised self-assessment tool designed to help adults explore whether they may be on the autism spectrum. Unlike brief online quizzes, the test is a structured and clinically informed screening test that examines lifelong neurodivergent traits, particularly those that may have gone unnoticed in childhood.
It was developed in 2008 by Dr. Riva Ariella Ritvo, Dr. Edward Ritvo, and colleagues at the Autism Research Group, Albert Einstein College of Medicine. It was designed as a self-report tool specifically for adults who may have gone undiagnosed with autism spectrum disorder (ASD) during childhood.
Unlike many earlier autism assessments, which were mainly focused on children, the screening test was created to capture the unique presentation of autism traits in adults, including difficulties with social interactions, communication, sensory sensitivities, and restricted interests.
The test assesses four key domains of autistic traits:
1. Language and Communication
This section evaluates difficulties with verbal and non-verbal communication, including challenges with conversational flow, interpreting tone, or understanding implied meanings, all common experiences among autistic individuals.
2. Sensory and Motor Responses
Many autistic adults experience sensory processing differences. This category explores sensitivities to sound, light, touch, or repetitive movements, which can influence daily comfort and interactions. Learn more about sensory & motor sensitivities in autism.
3. Social Relatedness
This domain looks at how you connect with others, from forming relationships to reading social cues and managing social anxiety. Persistent struggles in these areas are a core feature of autism spectrum conditions.
4. Circumscribed Interests and Routines
Also known as restricted or repetitive behaviours, this section examines a preference for routines, intense focus on specific topics, or resistance to change, all traits commonly associated with autism. Read more about autism demonstrating circumscribed interests.
This autism self-assessment is designed to provide a deeper understanding of how these patterns manifest in adult life. Whether you’re seeking personal insight or preparing for a conversation with a specialist, this tool can offer a strong foundation.

Score Ranges and Interpretation
Scores on the test range from 0 to 240. A score of 65 or higher is considered indicative of autistic traits, though interpretation should always take context into account.
Here’s a general guide to what different score bands may suggest:
| Score | Interpretation |
| Below 44 | Typically not autistic: Many neurotypical individuals fall within this range, though some autistic people may also score this low depending on how they interpret the questions. |
| 45–64 | Some autistic traits, but below clinical threshold: Traits may be present, but not to a degree that strongly suggests autism. Still, further assessment may be warranted, especially if lived experience aligns with autistic traits. |
| 65–89 | Mild to moderate likelihood of autism: This is the range where autism starts to be considered. Traits are likely persistent and noticeable, though not always formally diagnosed. |
| 90–129 | Moderate to strong likelihood of autism: A score in this range reflects significant traits, aligning with many common experiences of autistic adults. A diagnostic evaluation may be especially worthwhile. |
| 130–160 | Very strong likelihood of autism: This band often overlaps with average scores reported by clinically diagnosed autistic individuals in research studies. |
| Above 160 | Extremely high levels of autistic traits: This suggests an intense presence of neurodivergent characteristics, typically consistent with autism spectrum conditions. |
Remember, no self-assessment is definitive. Scores are best viewed as an indication, not a diagnosis, and professional evaluation is always recommended if you’re exploring neurodivergence more seriously. You may also be interested to see what happens during an adult autism assessment here.
Reliability & Critisisms
How Reliable is the RAADS-R?
The the Ritvo scale has been widely used in both clinical practice and academic research since it was first introduced in 2008. Reliability studies suggest that the test is effective at distinguishing autistic adults from non-autistic adults, particularly when combined with other assessments. To improve practicality, shorter tools have been explored, including the development of the RAADS-14 short version in 2023.
That said, no screening tool is perfect. False positives and false negatives are possible, especially for individuals with co-occurring conditions such as ADHD, anxiety, or depression. This diagnostic questionnaire should therefore be viewed as a helpful screening step, not a definitive diagnosis.
👉 The test has been validated in multiple populations, including a 2024 German validation study of the Ritvo scale which confirmed its high sensitivity and specificity.
Criticisms of This Screening Instrument
Although this autism screening test is well established, it has faced some criticism within the autism research community:
- Self-report limitations – answers depend on the individual’s own interpretation of the questions.
- Cut-off scores – thresholds may not reflect the full diversity of autism presentations.
- Overlap with other conditions – traits of anxiety, OCD, or ADHD may influence scores.
These criticisms highlight why this should be seen as a useful guide rather than a final word. Professionals often recommend using it alongside other tools and clinical evaluation.
👉 While this specific adult autism self-test remains widely used, a recent systematic review of autism screening tools highlighted variability in accuracy across self-report instruments.
How This Autism Screening Test Helps Adults
For many adults, especially those who may not have been identified as autistic in childhood, this test can provide clarity, validation, and a starting point for further exploration. Some of the key benefits include:
- Encouraging self-reflection on lifelong social, sensory, or communication challenges.
- Supporting conversations with healthcare providers when seeking a referral or diagnosis.
- Helping adults better understand their personal experiences and relationships.

The Ritvo Autism Asperger Diagnostic Scale vs Other Autism Tests
This screening instrument is just one of several recognised tools for assessing autistic traits. Each has its own strengths, and many people choose to take more than one:
- Autism Quotient (AQ) Test – a widely used 50-question self-assessment for adults.
- CAT-Q (Camouflaging Autistic Traits Questionnaire) – focuses on masking and compensation strategies.
- ADOS-2 (Autism Diagnostic Observation Schedule) – considered the gold-standard diagnostic assessment, administered by clinicians.
This autism screening tool stands out for its comprehensive coverage across multiple domains, but using it alongside other questionnaires can give a more complete picture of autistic traits.

Why Should You Take the RAADS-R Test?
If you’ve ever felt that your lifelong behaviours, sensitivities, or social interactions might align with autism traits, but weren’t recognised as a child, this test can offer meaningful clarity. This particularly suited for adults exploring undiagnosed autism, helping uncover patterns that standard childhood-focused assessments often miss.
- Comprehensive Assessment: This isn’t a surface-level checklist. The RAADS–R explores a broad range of traits across emotional regulation, communication, and sensory experiences, building a more complete picture of how autism may present in adulthood.
- Specifically for Adults: Many adults seek answers later in life, especially when childhood traits were overlooked or misunderstood. This test is tailored to evaluate behaviours that may have gone unrecognised during developmental years.
- Empowering Insights: Understanding your neurotype can be transformative. The RAADS–R helps individuals identify their strengths and challenges, fostering greater self-awareness and providing direction on whether to seek a formal autism diagnosis or further support.
Taking the RAADS–R through NeuroDirect not only provides a structured self-assessment, it also connects you with follow-up resources. From other online autism and ADHD tests to our directory of neurodivergent specialists, we’re here to support your next steps.
