What is the AuDHD Test?

The AuDHD Test is a free 20-question self-screen for adults who suspect they may have both autism and ADHD. Questions are drawn from validated instruments — RAADS-14 for autism traits and ASRS-style items for ADHD — translated into plain, identity-first English. Each question uses a 4-point frequency scale rather than a 1–5 agreement scale because lived-experience review found frequency framing reduces ambiguity for AuDHD adults whose traits are situational, not constant. The test takes 5 minutes and you can skip any question.

Is the AuDHD Test a diagnosis?

No. It is a screen — a starting point. A formal AuDHD assessment requires a qualified psychiatrist or psychologist with adult autism and ADHD experience, ideally one who works with neurodivergent adults regularly and does not still use functioning labels or recommend ABA. The result page is built to tell you what your score does mean (which trait clusters showed up), what it does not mean (a diagnosis), and what to do next.

How accurate is an online AuDHD test?

Online screens can identify patterns that warrant professional follow-up. They cannot replace structured clinical assessment with collateral history, behavioural observation, and rule-outs. A 'strong indicators' result on this screen is a real signal worth taking to a clinician. A 'few indicators' result is not a clean ruling out — particularly if you mask heavily, as many late-diagnosed AuDHD adults do. Use it as one input, not the verdict.

AuDHD is the lived experience of being both autistic and ADHD. Roughly 40–50% of autistic people also have ADHD, and the combination produces a profile that doesn't fit either condition alone. You may hyperfocus then completely freeze, crave routine and crave novelty, mask socially while burning out internally. The two conditions don't just add — they interact. AuDHD is increasingly recognised as a profile worth understanding in its own right rather than 'autism plus ADHD on the side'.

I scored high. What do I do?

Take a breath. A high score on a screen is information, not a verdict. Three steps: (1) read our AuDHD long-form guide so you understand the profile in depth; (2) if you want to pursue formal assessment, our diagnosis page lists ND-affirming clinicians who specifically work with adult AuDHD; (3) consider an ND-affirming therapist for ongoing support — particularly if you've been masking for decades, the unmasking process is itself work. None of these steps need to happen this week. Move at your pace.

I scored low but I still suspect AuDHD. What now?

Low scores on AuDHD screens are most often due to one of three things. (1) Masking — many AuDHD adults score lower than they 'should' because they answer based on how they appear, not how it feels. (2) The questions don't quite map to your specific traits (every AuDHD profile is different). (3) You may be autistic-only, ADHD-only, or another ND profile entirely. Try our Neurodivergent Test for a wider screen, or the Sensory Profile Test if sensory is your loudest signal.

Why do you use 'AuDHD' instead of 'autism with comorbid ADHD'?

Two reasons. First, 'AuDHD' is the term the community uses — autistic adults with ADHD adopted it years before clinical literature caught up, and it's now the dominant self-identification on Reddit, TikTok, and ND adult forums. Second, the clinical 'comorbid' framing treats AuDHD as two separate diagnoses that happen to coexist. Lived experience and emerging research suggest the two interact: hyperfocus + executive dysfunction is its own thing, not 'autism trait + ADHD trait stacked'. We use AuDHD because it names the actual experience.

Do you store my answers?

No. Your answers live in your browser tab and disappear when you close it. We don't store quiz responses, attach them to your email, or pass them to anyone — not Beehiiv, not Plausible, not Google Analytics. If you email us your result for context, that email is stored only because email is stored. We don't keep a database of test responses.

What AuDHD actually is

AuDHD is the lived experience of being both autistic and ADHD at the same time. The estimate from peer-reviewed work over the last decade is that 40–50% of autistic people also meet ADHD criteria, and a similar overlap runs in the other direction: a substantial fraction of ADHD adults turn out to be autistic when assessed properly. The two conditions interact, not just stack. AuDHD is increasingly recognised as a profile worth understanding in its own right.

Until 2013 the DSM forbade diagnosing autism and ADHD in the same person — the rule, removed in DSM-5, was that an ADHD diagnosis ruled out autism and vice versa. That created a generation of adults who were correctly identified as one or the other in childhood and left to discover the second half in their thirties or forties. AuDHD-as-a-thing emerged from that generation telling each other, mostly on Reddit and Twitter, that the standard advice for each condition individually didn’t quite work for them.

Why the two together feel different

Most online “am I autistic” or “am I ADHD” tests treat the two conditions like checklists you tick or don’t. AuDHD people often score in the “maybe” middle on both, because each condition is partially masking the other and the symptoms cancel where they oppose.

A few specific examples of what that looks like in daily life:

Routine and novelty at the same time. Autistic brains often crave sameness; ADHD brains often crave novelty. AuDHD adults often build elaborate routines around a small set of high- interest topics that they can dive deeply into for hours, and they find both pure repetition and pure variety equally exhausting.
Hyperfocus, then total executive failure. The ability to spend six hours straight on something you find interesting, followed by complete inability to start a one-minute task you find boring. This is the most common AuDHD signature in adult self-reports.
Social masking that drains a finite battery.Autistic masking is usually framed as performing neurotypical social behaviour. ADHD masking is usually framed as performing attention and conscientiousness. AuDHD masking is both, and the cumulative cost shows up as burnout in the late twenties to early forties — the years when most late-diagnosed AuDHD adults finally seek help.
Sensory load on top of dopamine seeking. The autistic side keeps the sensory environment small; the ADHD side keeps reaching for stimulation. The result is often a person who needs both an extremely controlled home environment andconstant new input within it — a curated chaos.
Interoception that ranges from blind to flooded.AuDHD adults frequently report not noticing they’re hungry or thirsty for hours, then crashing — combined with intense emotional responses that seem disproportionate to the trigger because the build-up wasn’t tracked.

How this test was built

Three sources fed the question set:

RAADS-14 (autism)— the 14-item short form of the Ritvo Autism & Asperger Diagnostic Scale, a validated adult autism screen. We use a subset of items that lived-experience review identified as still discriminating in AuDHD adults — we dropped items where ADHD-side traits would push a true AuDHD adult to score lower than they should.
ASRS-v1.1 (ADHD)— the Adult ADHD Self-Report Scale, the WHO-standard adult ADHD screen. Same approach: items adapted to plain language, frequency-scale framing kept.
AuDHD-overlap items— questions on the specific signatures listed above (hyperfocus + executive failure, interoception flooding, masking burnout, monotropism). These are not from a single validated instrument because no validated AuDHD-specific instrument yet exists. They are drawn from adult self-report literature and reviewed against AuDHD community Reddit and Twitter threads going back five years.

The 4-point frequency scale (Almost never / Sometimes / Often / Almost always) is borrowed from ASRS-style rather than the RAADS agreement scale. In our pilot review, AuDHD adults consistently found frequency framing easier than agreement — AuDHD traits are often situational, and “I agree with this statement” loses that nuance.

What the three result bands mean

The total score ranges from 0 to 60. We use three bands:

Few indicators (0–19).AuDHD doesn’t clearly emerge from your answers. That’s real information. One caveat: if you’ve been masking heavily for a long time, you may answer based on how you appear rather than how it feels — consider taking the test a second time answering for the internal experience.
Some indicators (20–36).Several AuDHD-typical traits show up, particularly around executive function, masking, and sensory needs. Not strong enough for a clean “yes”, not weak enough to dismiss. Worth reading the long-form AuDHD guide and possibly the autistic-only or ADHD-only screens.
Strong indicators (37–60).Your responses align strongly with AuDHD across multiple dimensions. If you haven’t already, this is worth taking to a clinician who specifically understands adult AuDHD — not a generalist who will diagnose one condition at a time.

The result page also shows a dimension breakdown: which clusters of traits (sensory, masking, executive function, hyperfocus, regulation, interoception, monotropism) showed up strongest. Two AuDHD adults can score the same total and have very different profiles — the breakdown matters more than the headline number when you take the result to a clinician.

What to do next, depending on your result

The result page links to three specific next steps. Briefly, here they are:

If you want a formal assessment: read our diagnosis guide. It explains what the assessment process actually involves, what to ask a clinician to check whether they’ll treat AuDHD as one thing or two, what the cost ranges look like in the US / UK / EU, and which providers we’ve heard back about from the community.
If you want ongoing support: see our therapy guide. Most therapists are generalists; not all generalists know what neurodivergent-affirming actually means in practice. We list the specific questions to ask a therapist on a first call to find out whether they’ll be a good fit.
If you just want to understand: read the full long-form What Is AuDHD?guide. Masking, burnout, executive function, hyperfocus, sensory load, the interaction between the two conditions, and the things AuDHD adults wish they’d known earlier.

A note on women and late-diagnosed adults

The clinical literature on autism and on ADHD was, for most of the twentieth century, built almost entirely on white boys. Women and late-diagnosed adults consistently present differently — more masking, more anxiety co-presentation, more internalised symptoms — and have been routinely missed by tools calibrated on the original samples. If you’re reading this and you’re a woman who was told as a child you were “sensitive” or “just anxious”, you are far from alone. Our AuDHD in Women guide goes deep on this.

Who built this

Neurodiverge is a small independent team. We aren’t a clinic. We aren’t selling assessments. We don’t take ad money from clinical providers we wouldn’t recommend to our own friends. The screens, the long-form guides, the editorial — all reviewed by autistic and ADHD adults before publication. We credit contributors on every guide. Read more on the About page.
