Frequently Asked Questions
What is the RAADS-R?
The RAADS-R is a comprehensive 80-question screening tool designed to identify autistic traits in adults. Developed by Dr. Riva Ariella Ritvo and colleagues, it evaluates 4 key areas — Social Relatedness, Circumscribed Interests, Sensory Motor, and Language.
How accurate is this test?
The RAADS-R has been validated in research studies and shows high sensitivity (97%) and specificity (100%). However, it's a screening tool — not a diagnostic test. A score of 65+ suggests you may benefit from a comprehensive evaluation by a specialist.
What does my score mean?
Scores range from 0 to 240. Below 65 suggests minimal traits. 65-129 indicates moderate traits and warrants further evaluation. 130+ suggests significant traits and strongly indicates the need for a comprehensive evaluation. You'll also get subscale scores for the 4 key areas.
Can this test diagnose autism?
No — this is a screening tool only. An official diagnosis requires a comprehensive evaluation by a qualified healthcare professional, such as a psychologist or psychiatrist who specializes in autism. The RAADS-R can help identify traits that warrant further assessment.
How is RAADS-R different from AQ-10 or AQ-50?
RAADS-R is more comprehensive — 80 questions vs. 10 or 50. It uses a unique 4-point scale that captures how traits change over time (childhood vs. adulthood). Plus, it gives detailed scores across 4 key areas, making it ideal for adults seeking a thorough self-assessment.
Is my data private?
Yes. All your responses are stored locally in your browser only. No data is sent to any server or third party. You can clear your results anytime by clearing your browser data.
Can I retake the test?
Yes, you can retake it anytime. However, for the most accurate results, try to answer honestly based on your typical experiences throughout your life — not how you wish to be or think you should answer.
How long does the test take?
The RAADS-R typically takes about 20 minutes. Take your time to read each question carefully and answer honestly. You can pause and resume anytime — your progress is saved in your browser.
Can I share my results with my doctor?
Absolutely! You can print or screenshot your results to share with your healthcare provider. Your subscale scores can be particularly helpful for specialists conducting a comprehensive evaluation.
