Is the RAADS R test accurate?
The Revised Asperger Autism Diagnostic Scale-Revised (RAADS-R) test is a fundamental instrument used in the diagnostic process of Autism Spectrum Disorder (ASD), particularly in adults. This scale is globally recognized and utilized by clinicians and ABA agencies due to its reliability and effectiveness.
For individuals who suspect they might be on the autism spectrum, especially adults, the RAADS-R self-report questionnaire often forms a crucial part of the assessment. Nonetheless, it’s pretty standard to wonder, “Is the RAADS-R test accurate?” In this blog post from the ABA Centers of Washington, we’ll delve into how the RAADS-R test stands apart from other autism assessments, its strengths, and the criticisms it faces, thereby offering you a more comprehensive understanding of the various tests available if you or a loved one are suspecting ASD.
Moreover, if you’re in search of autism diagnostic services, our team at the ABA Centers of Washington comprises professionals from diverse fields such as psychology, education, and behaviorism.

The RAADS-R Test: Tracing its Origins
The RAADS-R was developed by Dr. Riva Ariella Ritvo in 2011. Its primary aim was to highlight the most common characteristics of autism and bridge the gap between screening for the disorder and the needs of the neurodiverse adult population, a group whose requirements often remain unaddressed due to the absence of an official diagnosis. The steady increase in the autistic population both in the United States and globally emphasizes the pressing need for reliable resources to diagnose autism in adults. Therefore, when selecting a test, it’s essential to consider each aspect of the assessment in line with individual preferences and necessities.
The RAADS-R test is a revised version of the original RAADS test from 2008. It encompasses an 80-question assessment that delves thoroughly into the symptomology of autism, including aspects like social relationships, sensorimotor function, and language, which were present in the original test. However, it also integrates an evaluation of personal interests. Individuals over 16 years who possess an IQ within the normal range can self-administer the RAADS-R test.
What to Anticipate from the RAADS-R Test
This method of evaluating autism in adults can offer a more precise diagnosis of ASD. It covers several areas through its questions:
Language:
The language evaluative subscale in the RAADS-R addresses seven statements, focusing on:
• Echolalia: This refers to instances where the individual repeats predetermined language that they’ve heard previously in movies, television, or slogans.
• Literalism: This pertains to the difficulty in interpreting sarcasm, metaphors, or inferences.
• Small Talk: This assesses the ability to engage in conversations on non-preferred topics.
Social Interaction:
This evaluative subscale includes 39 statements, concentrating on aspects of socialization such as:
• Mentalization: This indicates difficulty in understanding what another person is feeling or thinking.
• Mutual Interests: This reflects a preference for interacting with people who have similar interests.
• Outsider: This represents feelings of being different from the majority.
• Openness: This refers to a tendency to ask inappropriate questions or directly point out others’ mistakes.
• Dialectical Reciprocity: This denotes difficulty in participating effectively in a conversation.
• Emotional Reciprocity: This signifies challenges in identifying emotional responses in social interactions.
• Object Permanence: This means an inability to miss others when they are absent.
• Relationship Maintenance: This relates to difficulty in forming and maintaining relationships.
• Nonverbal Communication: This implies difficulty in understanding gestures and social cues.
• Imitation: This suggests a tendency to mimic the behavior of others.
Sensory-motor:
This evaluative subscale consists of 20 statements addressing:
• Voice Volume: This involves significant fluctuations in volume when speaking.
• Voice Difference: This pertains to the use of voices that are not age-appropriate.
• Motor Control Problems: This refers to difficulties in coordination and general clumsiness.
• Sensory: This indicates seeking stimuli, even if they’re painful or overwhelming, and experiencing anxiety in the face of overstimulation.
Circumscribed Interests:
This subscale comprises 14 statements divided into:
• Preference for Details: This focuses on attention to details rather than the overall picture.
• Distress at the Unexpected: This signifies a dislike for changes in routine.
• Special Interests: This refers to having consistent and focused interests.
To respond to the questions, test takers have four options:
• “True now and when I was young”
• “True now only”
• “True only when I was under age 16”
• “Never true”
Interpreting the RAADS-R Test Results
The total scoring of the test depends on ranges from 0 to 240 points. A higher score means a greater likelihood of having ASD. The test employs two different scoring methods: paper-based and automated.
Here are some potential scores and their general interpretations:
• 25: No likelihood of ASD
• 50: Posses autistic traits but it is unlikely to have the disorder
• 65: Minimum score required to identify autism
• 90: Suggests the presence of autism spectrum, although neurotypical individuals may also achieve this score
• 130: Typical score indicating the presence of autism
• 160: Strong indicators for an autism diagnosis
• 227: Maximum score indicating autism
It’s crucial to understand that without a comprehensive evaluation, no test not administered by a professional certified to diagnose ASD can provide a definitive result. The RAADS-R test is a tool that forms part of a comprehensive assessment, so autism professionals can utilize its results to support or corroborate information leading to a diagnosis.
Advantages of Utilizing the RAADS-R for Autism Assessment
- Reliable Results: Based on research conducted by the Journal of Autism and Developmental Disorders, researchers found that the RAADS-R can be a useful addition to clinical diagnostic practices, as it exhibits a specificity of 100% and a sensitivity of 97%, leading to reliable results.
- Enables Self-Assessment: The capacity to administer this test independently allows individuals to recognize their symptoms and gain a deeper understanding of their behaviors.
- Enhances Communication in Clinical Settings: Undertaking the test and getting a high score may encourage some individuals to seek consultation in a clinical setting regarding their experiences and results. Communication in clinical settings can aid in facilitating discussions with healthcare professionals and promoting comprehension of their needs.
- Facilitates ASD Symptom Identification: The RAADS-R test is a reliable tool in detecting autism symptoms in individuals with diverse cognitive abilities, thereby aiding many healthcare professionals and experts in autism in the diagnostic process.
Drawbacks of the RAADS-R Test
- Necessitates Reflection on Past Experiences: This test requires reflection on past experiences and acknowledgment of behavioral patterns, which, while beneficial, can be challenging.
- Potential for Inappropriate Referrals or Comorbid Conditions: There is a possibility for inappropriate referrals or the presence of comorbid conditions that may affect the results.
- Lack of Assistance: Certain questions require assistance for proper understanding, which could result in confusion or misinterpretation.
