About AuDHD Test
Free, evidence-based screening for combined autism and ADHD traits
Our Mission
audhdtest.org exists to make neurodivergent screening accessible to everyone, regardless of location, language, or financial means. We believe that understanding your neurocognitive profile is the first step toward getting appropriate support. Too many people go undiagnosed simply because they lack access to screening tools — we aim to change that.
Scientific Methodology
Our screening combines two internationally validated instruments to assess both autism and ADHD traits in a single session:
AQ-10 (Autism Spectrum Quotient — 10 items): Developed by the Autism Research Centre at Cambridge University. It has a sensitivity of 0.88 and specificity of 0.91, making it one of the most reliable brief autism screening tools available. Clinical cutoff: 6/10.
ASRS v1.1 Screener (Adult ADHD Self-Report Scale v1.1, 6-question Screener): Developed with the World Health Organization (WHO) and the Workgroup on Adult ADHD (Kessler et al., 2005). Each answer scores 0–4; a total of 14 or more out of 24 is a positive screen.
Open & Free
The screening itself is completely free — no account required, no payment, no data selling — and we use privacy-friendly analytics (Plausible) that do not track individual users. An optional AI-written report is available for purchase; it is never required to see your scores or read what they mean. The screening is available in 12 languages to serve a global audience.
