RAADS-R Test is a private, browser-based adult autism self-assessment designed for thoughtful reflection. It includes all 80 questionnaire items, calculates an overall result with four domain breakdowns, and provides clear research context without requiring an account. The free web application helps adults organize long-standing patterns in communication, sensory experience, routines, and focused interests before deciding whether to seek professional guidance. It clearly explains that screening is informational rather than a medical diagnosis and keeps the experience accessible and privacy-conscious.
