CAT-Q: Camouflaging Autistic Traits Questionnaire

The CAT-Q is a 25-question self-report questionnaire that measures how much you camouflage — or “mask” — autistic traits in social situations. Take it free, in your browser — your answers stay on your device.

25 questions About 10 minutes Private — runs in your browser For adults
This is a screening questionnaire, not a diagnostic test. It measures camouflaging, not autism itself, and cannot confirm or rule out a diagnosis. Use your results as a starting point for a conversation with a qualified clinician.

What the CAT-Q measures

The CAT-Q was developed by Laura Hull, William Mandy, Meng-Chuan Lai, Simon Baron-Cohen, and colleagues to measure social camouflaging — the conscious and unconscious strategies people use to hide autistic traits or compensate for social difficulties. It looks at three kinds of camouflaging:

CompensationActively working around social challenges — for example, scripting conversations in advance or copying other people's body language.
MaskingHiding autistic traits or presenting a non-autistic-seeming persona to others.
AssimilationPushing yourself to fit in and feel part of a group, often at a real personal cost.

Unlike trait questionnaires such as the RAADS-R, the CAT-Q doesn't measure autistic traits themselves. It measures the effort you put into hiding or managing them — which is why the two are often used together.

Who should take the CAT-Q

It's designed for adults. It may be especially useful if:

  • You suspect you might be autistic but “pass” as non-autistic in most settings.
  • Socialising leaves you exhausted, even when it seems to go well.
  • You rehearse or script conversations, or copy other people's expressions and mannerisms.
  • You often feel like you're “performing” a version of yourself around others.
  • You scored lower than expected on other autism screeners, but the questions still described you.
  • You already know you're autistic and want to understand your masking and the toll it takes.

Because heavy camouflaging can lower your scores on trait-based tests, the CAT-Q is often taken alongside the RAADS-R rather than instead of it.

How to read your score

When you finish, the tool totals your answers into a score from 25 to 175, plus a separate score for each of the three subscales.

In the validation research (Hull et al., 2019), total scores above about 100 were linked to higher levels of camouflaging. For reference, autistic adults averaged roughly 110–124 and non-autistic adults roughly 91–109, varying by gender. This is context, not a strict cutoff.

Your three subscale scores show which camouflaging strategies you rely on most:

SubscaleWhat it reflectsMax
CompensationStrategies that work around social difficulty63
MaskingHiding traits or performing a persona56
AssimilationEffort to fit in and feel you belong56

One important point: because masking hides autistic traits, a high CAT-Q score alongside a lower score on a trait test like the RAADS-R can itself be meaningful — it may suggest you're autistic and camouflaging effectively. Bringing both sets of results to a clinician gives the fullest picture.

Frequently asked questions

What is camouflaging or “masking”?

Camouflaging is the set of strategies people use — often without realising it — to hide autistic traits or compensate for social difficulty, so they appear more “typical.” It's common among adults diagnosed later in life, and is reported especially often by women and gender-diverse people. It can be effective on the surface while being genuinely exhausting underneath.

Does a high score mean I'm autistic?

No. The CAT-Q measures how much you camouflage, not whether you're autistic. A high score means you use a lot of camouflaging strategies — which is worth exploring with a clinician, ideally alongside a trait screener and your history.

How long does it take?

Most people finish the 25 questions in about 10 minutes. There's no time limit.

My CAT-Q was high but other autism tests were lower. What does that mean?

This pattern is exactly what the CAT-Q is built to surface. Effective masking can suppress your scores on trait-based tests like the RAADS-R, so a high CAT-Q with a lower trait score can point toward autism that's being camouflaged. It's a useful thing to raise with a provider.

Is my information private?

Yes. The questionnaire runs entirely in your browser. Your answers and results stay on this page on your device — nothing is sent to us or stored anywhere unless you choose to print, save, or email your results yourself.

Should I take the CAT-Q or the RAADS-R?

Ideally both. They measure different things — the RAADS-R looks at autistic traits, while the CAT-Q looks at how much you hide or manage them. Taken together, they give a clinician a much fuller starting picture than either one alone.

What do the three subscales mean?

Compensation is using strategies to work around social difficulty. Masking is hiding autistic traits or presenting a non-autistic-seeming persona. Assimilation is the effort to fit in and feel you belong. Your scores show which you lean on most.

What should I do with my results?

Print, save, or email them to yourself and bring them to an appointment — along with your RAADS-R results, if you've taken it. They're most useful as a starting point for a conversation with a provider.
