AuDHD Test

AuDHD Test is a free web-based screening tool that combines two clinically validated instruments — the AQ-10 for autism traits and the ASRS-5 for ADHD traits — into a single 16-question assessment. The result is a simultaneous screen for both conditions, returning separate scored breakdowns for each within about three minutes. No account is needed, and results are delivered immediately on completion.

Who It Is For

The tool is aimed primarily at adults who suspect they may have undiagnosed ADHD, autism, or both. It is particularly relevant for people who have noticed traits that don't fit neatly into one diagnosis — restlessness alongside sensory sensitivities, or executive function difficulties alongside a strong preference for routine. Late-identified neurodivergent adults, women and non-binary individuals whose traits are often masked or overlooked in clinical settings, and people facing long diagnostic waitlists are among the most common users.

Clinicians and coaches sometimes share the link as a low-friction pre-screening step before a formal appointment.

Why AuDHD Specifically

Research suggests that 50–70% of autistic people also meet criteria for ADHD, yet the two conditions are frequently assessed in isolation. When both are present, traits can mask or amplify each other, making a single-condition screen less informative. AuDHD Test addresses this by running both screens in parallel and presenting the scores side by side, giving users a clearer starting picture before they pursue professional evaluation.

The term AuDHD itself is increasingly used in neurodivergent communities to describe this overlap, and the site reflects that framing throughout.

What the Screening Covers

The main AuDHD Quick Screening draws on the AQ-10 (sensitivity 0.88, specificity 0.91) and the ASRS-5 (AUC 0.94), both of which are among the more accurate brief instruments in their respective categories. The 16 questions cover sensory sensitivity, attention regulation, social communication, and impulsivity, among other domains.

Beyond the combined screen, the site offers five additional assessments at different depths:

• ADHD Test — standalone ASRS-5, six questions, around one minute
• Autism Test — standalone AQ-10, ten questions, around two minutes
• RAADS-R — an 80-question autism screen across four dimensions, suited to users who want more granular results
• Masking Test (CAT-Q) — 25 questions measuring how much a person camouflages autistic traits, a dimension most screeners omit entirely
• Full Assessment — combines RAADS-R, ASRS-5, and CAT-Q into a 111-question evaluation taking roughly 25 minutes

This range lets users start with a quick check and escalate to a more detailed screen if the initial results warrant it.

Workflow and Access

The flow is straightforward: answer the questions, receive scored results, and optionally save them via email. There are no paywalls, no upsells mid-flow, and no registration requirement. Results include a breakdown by condition rather than a single combined score, which makes them more useful as a conversation starter with a GP or psychiatrist.

The interface is available in 12 languages, which extends accessibility beyond English-speaking users — a meaningful consideration given how underdiagnosed both conditions remain in many regions.

Limitations Worth Knowing

The tool is a screening instrument, not a diagnostic one. A positive screen indicates that traits are present at a level that may warrant further evaluation; it does not confirm a diagnosis. Self-report formats also carry inherent limitations — people with low self-awareness of their own traits, or those who have heavily masked them over time, may score differently than their clinical profile would suggest.

There is no version designed for children or for parent-report use, so the tool is not appropriate for evaluating younger populations. The next-step recommendations provided after results are general rather than region-specific, so users looking for local referral pathways will need to seek that information elsewhere.

Pricing

AuDHD Test is entirely free. All six assessments, full results, and the multi-language interface are available without payment or subscription. The optional email feature for saving results is the only point where personal information is requested, and it is not required to access results.
