CAT-Q: measuring autistic camouflaging
Start the free assessment Free, about 10 to 15 minutes
Short answer
The CAT-Q (Camouflaging Autistic Traits Questionnaire) is a 25-statement self-report measure of social camouflaging, published in 2019 by Laura Hull and colleagues. Each statement is rated on a seven-point scale, giving totals from 25 to 175, with higher scores meaning more camouflaging. It measures masking and related strategies. It is not an autism screener and has no diagnostic cut-off.
Camouflaging is the umbrella term researchers use for the strategies some people use to fit in socially: hiding traits that might stand out, working hard behind the scenes to manage conversations, and pushing themselves into social situations to blend with others. Many autistic adults, especially those identified late, describe years of doing this without having a word for it. The CAT-Q was the first questionnaire built to measure it directly, and it was built from what autistic adults themselves described.

The three factors
- Compensation (9 statements): active strategies to make up for social difficulties, such as studying how others behave or preparing what to say.
- Masking (8 statements): monitoring and adjusting how you come across, so that others do not notice differences.
- Assimilation (8 statements): pushing yourself to blend in, often while feeling like you are performing or do not belong.
Looking at the three factors separately is often more revealing than the total. Two people with the same total might camouflage in very different ways: one through careful preparation, the other through constant self-monitoring.
How it was developed and tested
Why the CAT-Q is not an autism test
The CAT-Q measures behaviors, not autism itself. Non-autistic people camouflage too, for example someone with social anxiety who rehearses every conversation, or a person who hides who they are at work because of stigma. The 2019 paper reported no diagnostic cut-off, and a high score cannot tell you whether the reason you camouflage is autism.
Why camouflaging matters
Camouflaging can help people get through job interviews, keep friendships and avoid bullying. It can also be exhausting and can make difficulties invisible to doctors, teachers and employers. Research has linked heavier camouflaging with poorer mental health, including anxiety and depression, in autistic adults, though the direction of cause is still being studied. If you score high and feel worn out, that is worth taking seriously and talking about.
CAT-Q and RAADS-R together
People often take both, and they answer different questions. The RAADS-R asks how many autistic experiences you report now and in childhood. The CAT-Q asks how much effort you put into hiding or compensating for social differences. Someone who camouflages heavily may score lower on trait questionnaires than their experience warrants, which is one reason clinicians are interested in camouflaging. Even together, the two cannot diagnose autism.
A short form
Take the CAT-Q free
Because the CAT-Q was published under a Creative Commons Attribution license, SpectrumFox offers the official 25 statements and official scoring free at our CAT-Q tool, with full credit to the authors. Your result shows your total and three factor scores. We present it as a measure of camouflaging only, never as a sign of whether autism explains your experiences.
Frequently asked questions
Is the CAT-Q free?
Yes. The authors published it open access under a Creative Commons Attribution 4.0 license, which allows free use with credit. SpectrumFox hosts the official version free at /tools/cat-q, with the original wording and scoring.
Is the CAT-Q an autism test?
No. It measures social camouflaging, which both autistic and non-autistic people do. The 2019 paper reported no diagnostic cut-off. A high score describes effort spent fitting in, not a diagnosis. Only a qualified professional can diagnose autism.
How long does the CAT-Q take?
It has 25 statements on a seven-point scale, so it is quick compared with most trait questionnaires. The time depends mostly on how long you pause to think about real situations from your own life.
Who made the CAT-Q?
Laura Hull, William Mandy, Meng-Chuan Lai, Simon Baron-Cohen, Carrie Allison, Paula Smith and K. V. Petrides developed it, publishing the validation study in 2019.
