TL;DR
Masking is when autistic people consciously or unconsciously hide autistic traits to fit in. It costs energy and can lead to burnout, anxiety, and depression. CAT-Q is a validated questionnaire that measures the degree of camouflaging.
You arrive home after a long day at work. You drop your bag, close the door, and struggle to speak. Not because anything happened. Just because you've been holding yourself together for eight hours, and there's nothing left.
It's not tiredness. It's the price of having been yourself out there.
What many autistic people experience without having words for it has a name: masking. And for many, the first encounter with that concept is an experience of being recognised in a way they didn't know was possible.
Living as two people
Many autistic adults describe it as living as two people. The public version that performs social competence: asks follow-up questions, maintains eye contact at the right intervals, smiles at the right times. And the private version that collapses at home when no one is watching.
The problem is not the mask itself. The problem is that after 20 or 30 years, you can no longer tell the mask from the face behind it.
Psychologist D.W. Winnicott described in 1960 the concept of the 'false self': a social facade developed as protection against a threatening environment. For many autistic people, this is exactly what happens. The social persona is constructed so thoroughly that the authentic self becomes inaccessible, even to the person themselves. It is not conscious deception. It is survival that, over time, has become self-alienation.
What is masking?
Masking, also called camouflaging, is when autistic people consciously or unconsciously suppress autistic traits and mimic neurotypical behaviour in social situations. It is a survival strategy that can lead to exhaustion, identity loss, and delayed diagnosis. Hull et al. (2019) identified three central components:
Compensation is learning socially through intellect what others pick up intuitively. Practising small talk. Remembering to ask follow-up questions. Counting seconds to maintain appropriate eye contact.
Masking is hiding autistic responses in the moment: suppressing stimming, forcing yourself to make eye contact, holding back internal reactions even when they are intense.
Assimilation is trying to disappear into the group. Copying others' facial expressions and tone of voice, studying social scripts, adapting behaviour to every new context.
For many, it is not a conscious choice. After decades of practice, masking becomes automatic, a constant, invisible effort running in the background of every social interaction.
The price
Masking is effective. That's why it continues. But the price is high.
Social interaction becomes enormously draining, not because you are introverted, but because you are performing constantly. A full day of masking at work can leave a person with no energy for anything in the evening.
Over time, identity fragments. Prolonged masking can trigger autistic burnout: chronic exhaustion, skill loss, increased sensory and emotional sensitivity. It goes beyond stress. Research shows higher rates of anxiety, depression, and suicidal ideation in autistic adults who mask intensively.
And clinicians don't see it. The person has learned to hide it. Many women are not diagnosed until their 30s or 40s for precisely this reason.
Unconcealment
The Greek word aletheia (ἀλήθεια) means unconcealment: literally, that which is no longer hidden. For many autistic adults, a diagnosis is exactly that. Not a disease being uncovered, but a truth about yourself that is finally allowed to emerge.
Decades of exhaustion, social difficulty, and the feeling of being different suddenly gain coherence.
A diagnosis can trigger a profound identity crisis. Not because it is bad news, but because it forces the question: if the person I have been all these years was a performance, then who am I actually? That question is painful. It is also the beginning of reconstruction.
Unmasking is not a decision you make on a Tuesday. It is a psychological process that can take months or years. The masking existed for a reason: it protected against real social consequences. Beginning to let go of it requires figuring out which parts of your social behaviour are authentic and which are performance. For some, this is liberating. For others, it is anxiety-provoking, because it confronts them with a version of themselves they do not yet know.
Both experiences are normal.
CAT-Q: Measuring masking
CAT-Q (Camouflaging Autistic Traits Questionnaire) is a questionnaire developed by Hull et al. (2019) to measure the degree of camouflaging. It measures compensation, masking, and assimilation across 25 questions and is validated regardless of whether the person already has a diagnosis.
High CAT-Q scores correlate with higher levels of anxiety and depression. Masking is not neutral for mental health.
A high score does not diagnose autism, but it can indicate that further assessment is relevant. Take the CAT-Q free and anonymously on our website.
Assessment at Alethia
We use CAT-Q as part of our autism assessment battery, combined with RAADS-R, AQ, EQ, clinical interview, and ADOS-2 when indicated.
We are trained in recognising masked autism presentations. We know that a person can appear 'typical' in a conversation and still be autistic, because masking is exactly what it's designed to do: hide. Our approach is neuroaffirming throughout.

Frequently asked questions
No, all autistic people can mask. However, research shows that women tend to mask more than men. Some research suggests that non-binary and transgender autistic individuals also report higher levels of masking.
Yes. CAT-Q measures camouflaging, not autism. People with social anxiety, ADHD, or personality disorders can also score high. A high score is an indication that further assessment may be relevant, not a diagnosis in itself.
Autistic burnout is a state of deep exhaustion, skill loss, and increased sensitivity following prolonged masking and overload. It differs from ordinary burnout in that it often involves regression in daily skills, such as speaking, remembering, or performing basic tasks.
Yes. Psychoeducation and therapy can help understand masking patterns, identify safe spaces for less masking, and develop strategies for conserving energy. However, the goal of therapy should not be to teach better masking.
