CAT-Q test explained for adults

Short answer

The Camouflaging Autistic Traits Questionnaire, or CAT-Q, is a 25-item self-report measure developed and validated by Laura Hull and colleagues, building on earlier qualitative work. Its proposed factors are compensation, masking, and assimilation. The original study included autistic and non-autistic adults and describes research and possible clinical uses, but the CAT-Q cannot establish an autism diagnosis and has no validated diagnostic cut-off. A high score does not confirm autism, and a low score does not rule it out. NeuroType offers the questionnaire free for adult self reflection, with answers kept in the browser.

What the CAT-Q is and is not

The CAT-Q asks adults to rate 25 statements on a seven-point scale. The original study administered it online to autistic and non-autistic adults and found a three-factor structure with nine compensation items, eight masking items, and eight assimilation items. It reported strong internal consistency for the total scale and preliminary three-month test-retest results from a small autistic subsample.

Those psychometric findings do not make the CAT-Q an autism test. It measures self-reported camouflaging, not whether a person meets autism diagnostic criteria or how 'autistic' they are. Self-report can also be affected by interpretation, awareness, recall, and context. A score should not be used to confirm or exclude autism or to judge effort, virtue, or authenticity.

The three subscales explained

The original factor analysis proposed three related subscales. Compensation refers to reported strategies intended to manage social or communication difficulty. Masking refers to reported strategies intended to hide autistic characteristics or present a less autistic persona. Assimilation refers to reported strategies used to fit in during social situations.

These are questionnaire constructs, not three biological systems or three diagnostic categories. The validation paper supports calculating the proposed total and subscale scores, but it does not establish clinical thresholds or prove that one subscale pattern is more meaningful for an individual than the total.

What CAT-Q scores describe and what they do not

The possible total score is 25 to 175, with higher totals representing more frequent self-reported camouflaging on this questionnaire. In one exploratory subsample in the original paper, the mean item score was 4.79 among autistic participants and 3.48 among non-autistic participants; the groups still overlapped. These sample averages are not diagnostic cut-offs and should not be converted into a personal verdict.

Later group studies reported differences by gender and associations between camouflaging scores and mental-health measures. These are group-level associations. They do not show that camouflaging causes a particular outcome, that every autistic person camouflages, or that a given score predicts an individual's health. Distressing or suicidal thoughts require appropriate professional or urgent support regardless of a CAT-Q score.

Important limitations of the CAT-Q

The CAT-Q is self-report, so responses depend on how a person understands the statements and recalls or recognises their behaviour. The original recruitment was online, diagnostic status was self-reported, and the sample was not representative of every culture, age, educational background, disability profile, or communication style. Preliminary test-retest analysis involved only 30 autistic participants.

The measure records reported behaviour at the time of completion; it does not establish why that behaviour occurs, whether it is conscious, whether it is safe or harmful, or what action a person should take. Cross-sectional associations cannot establish causation. Cultural and situational expectations may also affect what respondents regard as camouflaging. Treat any score as limited descriptive data, not a diagnosis, prognosis, or treatment guide.

NeuroType CAT-Q status

NeuroType offers the CAT-Q tool free for adult self reflection under Creative Commons Attribution 4.0, with visible source attribution. Answers stay in the browser. After completion, an optional paid, non-clinical PDF report can use the aggregate total and three subscale scores; individual answers are not sent to checkout. Neither the free result nor the paid report can confirm or rule out autism or any condition. No clinician or solicitor has independently reviewed NeuroType's CAT-Q implementation or paid report template.

If the patterns described by the CAT-Q resonate strongly and you are considering formal autism assessment, a clinician with adult autism experience is the next step. NeuroType cannot diagnose, refer, or prescribe.
