Autism camouflaging (masking)
Definition
Autism camouflaging (also called masking) describes the conscious or unconscious strategies autistic people use to hide, suppress, or compensate for autistic traits in social situations to appear more neurotypical. The term encompasses behaviors as varied as suppressing stimming during meetings, rehearsing eye contact in mirrors, scripting conversational responses in advance, mimicking peers’ mannerisms, and concealing special interests in public-facing contexts. Camouflaging is measured by the Camouflaging Autistic Traits Questionnaire (CAT-Q), developed by Hull et al. (2019, Journal of Autism and Developmental Disorders), which decomposes camouflaging into three factors: compensation, masking, and assimilation.
Camouflaging is one of the most clinically and personally consequential phenomena in adult autism. It is associated with delayed diagnosis (particularly in women and gender-diverse adults), mental health costs (depression, anxiety, suicidality), and autistic burnout. It is also a coping strategy that genuinely allows many autistic people to function in environments not designed for them. The relationship between camouflaging and wellbeing is more complex than the simple framing of "camouflaging is bad" sometimes suggests — a 2025 longitudinal study found that the direction of association can vary depending on baseline camouflaging level.
Why it matters
Camouflaging matters at three levels.
For diagnosis: Standard adult autism assessment relies on observed traits (eye contact, social reciprocity, restricted interests). Camouflaging directly suppresses these observable features, which means clinicians evaluating an actively-camouflaging adult may not see the autism that is present. This is one of the central mechanisms by which adult women without intellectual disability are missed in autism evaluation, as documented in a 2025 narrative review of literature from 2010–July 2025. The result is a diagnostic-fairness problem with measurable consequences: years or decades of missed support.
For mental health: Camouflaging is energy-expensive in ways non-autistic people often underestimate. Sustained camouflaging across years has been linked to elevated rates of anxiety, depression, suicidal ideation, and autistic burnout. The mechanisms include cognitive load, identity erosion (the camouflaged self may feel inauthentic or false), social isolation (hiding autistic traits often hides genuine connection too), and the absence of the support that correct identification could provide.
For self-recognition: Many autistic adults camouflage so successfully and habitually that they do not recognize their own autism until camouflaging fails (during burnout) or until they encounter an account of camouflaging that names their experience. The CAT-Q has become widely used in self-recognition not because it diagnoses autism (it does not), but because it gives language to behaviors that the camouflaging adult has been performing automatically for decades.
Camouflaging vs masking vs passing
The terminology in this area is not fully standardized, and the most common terms have overlapping but distinguishable meanings:
- Camouflaging — the academic umbrella term, used most often in research literature. It encompasses all three Hull 2019 factors (compensation, masking, assimilation) and treats them as a coherent behavioral pattern.
- Masking — the most common community term and one of Hull’s three factors. In community use it is broader and roughly synonymous with camouflaging; in academic use following Hull it is narrower (specifically: hiding autistic traits or portraying a non-autistic persona). The Hull 2019 paper notes that masking may be less specific to autism than the other two factors and may overlap with general impression-management strategies.
- Passing — an older term, drawing analogy to "passing" in racial or LGBTQ+ contexts; means appearing as something one is not. Less common in autism literature today but still appears in autobiographical writing.
- Adaptive morphing — a recent term used in some autistic-community spaces; emphasizes that the behavior is an adaptation to environment rather than a deception, and that it shifts dynamically with context.
- Compensation — a Hull 2019 factor (one of three) and also a more general term in clinical neuropsychology. Compensation describes active strategies to manage social difficulty (e.g., learning rules of conversation explicitly) as distinct from masking (hiding behavior) or assimilation (trying to fit in).
This entry uses camouflaging as the umbrella term throughout. Where research findings are specific to one of the three Hull factors, the specific factor name is used.
The three-factor model (Hull 2019)
The CAT-Q’s factor analysis identified three distinct components of camouflaging that differ in their cognitive and emotional character. These are not mutually exclusive — an autistic adult typically engages in all three to some degree — but they have different functional purposes and different relationships to mental health outcomes.
Compensation
Active, learned strategies used to manage social difficulty. Compensation is forward-looking and often deliberate: rehearsing what to say before a meeting, learning rules of conversation explicitly (turn-taking, follow-up questions), studying neurotypical body language, preparing scripts for common social situations. Compensation requires significant cognitive effort but is often experienced as a useful skill rather than as deception.
Masking
Strategies used to hide autistic characteristics or to portray a non-autistic persona. Masking is concealing rather than compensating: suppressing stimming, hiding sensory discomfort, controlling facial expressions, holding back special-interest talk. Masking has the strongest association in Hull 2019 with anxiety and depression and may be less specific to autism than the other factors (i.e., non-autistic people also mask aspects of self for social reasons).
Assimilation
Strategies that reflect trying to fit in with others, often without a clear plan. Assimilation is the most passive of the three and overlaps with social conformity pressure: copying others’ behavior to blend in, hiding aspects of self that differ from peers, suppressing one’s natural communication style. Assimilation typically tracks more strongly with feeling out-of-place than with explicit deception. Hull 2019 found assimilation showed the strongest relationship with depression in non-autistic adults, suggesting it may capture broader social-conformity costs that are not specific to autism but are experienced acutely by autistic adults.
The three factors are correlated but distinct: an autistic adult may score high on compensation but low on masking (skillfully manages social situations but doesn’t feel inauthentic), or vice versa. The three-factor model is preferable to a single global "camouflaging" score for clinical use, although the total score remains the most commonly reported number in research.
The CAT-Q instrument
The Camouflaging Autistic Traits Questionnaire (CAT-Q) was developed and validated by Hull et al. (2019) in the Journal of Autism and Developmental Disorders. It is the canonical self-report instrument for camouflaging and is freely available for non-commercial research and clinical use.
Format and scoring
- Items: 25 statements about camouflaging behaviors
- Response scale: 7-point Likert (1 = strongly disagree, 7 = strongly agree)
- Total score range: 25–175
- Subscale ranges: Compensation 9–63 (9 items), Masking 8–56 (8 items), Assimilation 8–56 (8 items)
- Reverse-coded items: Several items in each subscale are reverse-coded so that higher scores consistently indicate more camouflaging
- Time: Approximately 5–7 minutes to complete
Validation and psychometrics
Hull 2019 validated the CAT-Q in a sample of 832 adults (autistic and non-autistic) recruited online. The three-factor structure replicated in confirmatory analysis. Internal consistency was strong: total CAT-Q Cronbach’s alpha = 0.94; compensation alpha = 0.91; masking alpha = 0.85; assimilation alpha = 0.92. Test-retest reliability over a 3-month interval was acceptable. The CAT-Q has since been validated in multiple languages including Dutch (van der Putten et al. 2023), Spanish (CAT-Q-ES), Italian, French, and others. The Dutch and Spanish versions are most commonly cited in 2024–2025 research.
What the CAT-Q does and does not do
The CAT-Q is not a diagnostic instrument for autism. It measures camouflaging behaviors only. A high CAT-Q score in a non-autistic person reflects general impression management or social conformity strain, not autism. A high CAT-Q score in a self-suspecting adult is one of several signals that autism evaluation may be warranted; it is not by itself sufficient evidence. Hull and colleagues have been explicit on this point: the CAT-Q quantifies a behavioral pattern that is more frequent in autism but not specific to it.
Who camouflages
Camouflaging is widespread across the autistic population but is unevenly distributed by sex, gender, age at diagnosis, and context.
Sex and gender
Most studies using the CAT-Q report higher camouflaging scores in autistic women than in autistic men, often substantially. The Hull 2019 validation sample, the Dutch CAT-Q-NL studies (van der Putten et al. 2023, 2025), and most subsequent replications find a clear sex difference favoring higher camouflaging in women. Autistic gender-diverse adults often report camouflaging scores comparable to or higher than autistic women.
The pattern is not universal. A 2025 Italian study of 65 autistic adults presenting to mental-health services (Bertelli group) found no significant sex differences in CAT-Q total or domain scores; the absence of a sex difference in this clinical sample may reflect that adults who reach formal mental-health services have similar camouflaging-driven impairment regardless of sex. Another 2025 study comparing women with ASD versus borderline personality disorder (BPD) found no significant CAT-Q difference between the two female groups, raising the possibility that camouflaging in women is partly a transdiagnostic adaptive response rather than autism-specific.
Diagnostic history
Late-diagnosed autistic adults, particularly those diagnosed in adulthood after years of symptom-misattribution, typically report higher CAT-Q scores than adults diagnosed in childhood. This is partly because successful camouflaging delays diagnosis (selection effect) and partly because adults who developed camouflaging as a survival strategy continue to deploy it after diagnosis.
Context dependence
Camouflaging is not a fixed trait. Most autistic adults camouflage more in some contexts (workplace, formal social events, with strangers) than others (home, with autistic friends, in solitary work). The CAT-Q captures self-reported general level of camouflaging, but the underlying behavior is highly responsive to environment, perceived stakes, and energy availability.
Mental health costs
Camouflaging has been consistently associated with poorer mental health in cross-sectional studies, although the recent 2025 longitudinal evidence complicates the simple causal interpretation.
Cross-sectional findings
The bulk of evidence comes from cross-sectional studies that find higher CAT-Q scores associated with:
- Anxiety — both generalized anxiety and social anxiety, with effect sizes in the moderate-to-large range across multiple samples
- Depression — the 2025 Italian study found that CAT-Q total significantly predicted lifetime depression (B = 0.053, p = 0.003) controlling for age, sex, and AQ score; depressed women had the highest CAT-Q scores in the sample
- Suicidality — the 2025 women+suicidality study (n = 471, including 72 autistic women) found anxiety mediates the link between camouflaging and suicidal ideation
- Autistic burnout — chronic camouflaging is one of the strongest predictors of burnout episodes (see section ix)
- Identity erosion — qualitative studies report a common theme of feeling that the camouflaged self is "not the real me"
The 2025 longitudinal nuance
Until 2025, all major studies of camouflaging and mental health were cross-sectional, leaving causal direction ambiguous. The first major longitudinal study (van der Putten et al., 2025, Autism) followed 332 Dutch autistic adults aged 30–84 (157 women) at two timepoints two years apart.
The finding was unexpected and contrary to the simple narrative: adults with high initial camouflaging showed a decrease in mental health difficulties over the two years, while adults with low initial camouflaging showed an increase. The authors note this does not invalidate cross-sectional associations but suggests the relationship is more complex than "camouflaging causes harm" — perhaps reflecting context, autonomy, reasons for camouflaging, or selection effects in who camouflages and who does not.
The current evidence-based interpretation: camouflaging is associated with mental health difficulties cross-sectionally, the association is robust across samples and methods, but the causal direction is not established and may run in either direction or both. Recommendations for autistic adults to "stop camouflaging" should be treated cautiously; the 2025 longitudinal data suggest that abruptly reducing camouflaging without addressing the environments that prompted it may not improve mental health and may sometimes worsen it.
The diagnostic-bias problem
Standard adult autism assessment relies heavily on observed behavior. Diagnostic instruments such as the ADOS-2 (Autism Diagnostic Observation Schedule) score behaviors that camouflaging directly suppresses: eye contact, gestural communication, conversational reciprocity, restricted interests revealed in conversation, repetitive behaviors. An adult who has spent decades training themselves to maintain eye contact, control hand stimming, follow conversational norms, and conceal special interests will produce an ADOS profile that differs significantly from an adult with the same underlying autism but less camouflaging history.
The mechanisms by which camouflaging produces under-diagnosis include:
- Behavioral suppression during assessment — the autistic adult may instinctively engage maximum camouflaging during a high-stakes evaluation, producing exactly the absence of observable autism that the assessment is looking for
- Compensatory verbal fluency — many camouflaging adults learn to talk smoothly about their experience, masking the underlying social difficulty in the very conversation meant to assess it
- Specialized rather than restricted interests — some autistic adults learn to discuss their interests in conventionally-appropriate ways (limited duration, framed as professional or hobbyist), making the restricted-interest criterion harder to identify
- Self-report instrument bias — instruments that ask about current traits may be answered honestly but reflect the camouflaged version of the person; instruments that ask about traits "as a child" or "without effort" tend to capture autism better in camouflaging adults
This is one of the central reasons why the RAADS-14 and similar self-report screens have become widely used: the wording often asks about traits that are present without active effort, and the screen often flags camouflaging adults whom in-person assessment misses. It is also why the 2025 narrative review on women without intellectual disability identifies camouflaging as one of the primary diagnostic-fairness problems in adult autism evaluation.
Autistic burnout
Autistic burnout is a state of chronic exhaustion, loss of skills, and reduced tolerance to stimulus that occurs in autistic adults, particularly those who have engaged in prolonged camouflaging. The concept was formalized in Raymaker et al. (2020, Autism in Adulthood), building on community accounts that long predated formal research.
Core features include:
- Pervasive exhaustion — not relieved by ordinary rest; persists for weeks to months
- Loss of skills — previously manageable tasks (work, communication, executive function) become difficult or impossible
- Increased sensory and social sensitivity — previously tolerable noise, light, or social interaction becomes overwhelming
- Reduced ability to camouflage — the person can no longer perform the camouflaging that previously allowed them to function in non-autistic environments
- Emotional dysregulation — tearfulness, irritability, dissociation, anhedonia
The connection to camouflaging is bidirectional: prolonged camouflaging is one of the strongest predictors of burnout, and burnout is often the event that reveals the extent of prior camouflaging to the autistic person themselves. Many late-diagnosed adults present to clinical services after a burnout episode, and the diagnostic conversation often retrospectively reveals years of camouflaging that the person had not previously recognized as such.
Burnout is distinct from depression, although the two often co-occur. Burnout typically responds to reduction in load (time off, environmental change, reduced social demands, autism-affirming accommodation) more than to standard depression treatment. Stimulant medication, antidepressants, and conventional psychotherapy may be needed for co-occurring depression but do not by themselves resolve burnout.
The unmasking process
"Unmasking" describes the gradual process of reducing camouflaging behaviors and allowing more authentic autistic presentation. It is a major theme in autistic-community writing post-diagnosis, but it is more complex in practice than the term suggests.
Selective rather than total
Most autistic adults who unmask do so selectively: unmasking with close friends and family, partial unmasking in autism-affirming workspaces, continued camouflaging in conventional professional contexts. Total unmasking across all domains is rare and often socially or professionally costly. The realistic goal for most adults is shifting the balance — spending more time in environments where camouflaging is unnecessary, and reducing camouflaging in environments that don’t require it.
Pacing and recovery
Unmasking is typically gradual, often spanning years. The decades of camouflaging cannot be undone in weeks. Adults who attempt rapid unmasking sometimes report a transitional period of increased social difficulty: the camouflaging skills are still rusty enough to be obvious in their suppression, the unmasked self has not yet been fully integrated, and the social environment has not yet adjusted. The 2025 longitudinal evidence on camouflaging and mental health (above) is a methodological reminder that the simple direction "unmask = better" is not always supported by data.
Therapeutic support
Therapy with neurodiversity-affirming clinicians is often helpful for unmasking. Such therapists treat autistic identity as a valid neurotype rather than a problem to be reduced, which makes unmasking a process of identity integration rather than symptom-reduction. Conventional therapy that treats autistic features as undesirable can paradoxically encourage continued camouflaging.
Common misconceptions
“Camouflaging is the same as lying about being autistic.”
False. Camouflaging is not deliberate deception in the moral sense. Most camouflaging behaviors are performed automatically, often unconsciously, and for self-protective rather than manipulative reasons. Many autistic adults do not recognize they are camouflaging until well into adulthood. The framing of camouflaging as deception misunderstands the phenomenon and adds undeserved moral weight to a survival strategy.
“Only women camouflage.”
False. Most studies report higher camouflaging scores in women than men, but autistic men also camouflage substantially. The 2025 Italian clinical sample found no sex difference. Gender-diverse autistic adults often report the highest scores. Camouflaging is widespread across the autistic population; the sex difference is one of degree and visibility rather than presence versus absence.
“Camouflaging means you don’t really have autism.”
False, and this misconception causes real harm by gatekeeping diagnosis and self-recognition. The capacity to camouflage requires significant cognitive resources but does not negate the underlying autism. The 2019 Hull paper, the 2020 Raymaker autistic burnout paper, and the 2025 narrative review on women without intellectual disability all directly address this misconception. Successful camouflaging often delays diagnosis; it does not invalidate it.
“Camouflaging is always harmful and should be stopped immediately.”
Oversimplified. The cross-sectional association with poor mental health is robust, but the 2025 van der Putten longitudinal study found that adults with high initial camouflaging actually showed decreased mental health difficulties over two years. Camouflaging is also a coping strategy that allows many autistic people to function in environments not designed for them. Rapid, total unmasking without environmental change can produce social and professional costs without mental-health benefit. The realistic recommendation is gradual, selective reduction in environments where it is safe to do so.
“A high CAT-Q score means you’re autistic.”
False. The CAT-Q measures camouflaging behavior, not autism. Non-autistic adults can score high on the CAT-Q for reasons unrelated to autism: general social conformity strain, impression management, transdiagnostic adaptation in women (e.g., the 2025 ASD-vs-BPD finding). A high CAT-Q score is one signal among several that warrants consideration; it is not by itself diagnostic. Hull and colleagues have been explicit that the CAT-Q is not a diagnostic instrument.
“Autistic burnout is just regular burnout.”
False. The Raymaker et al. 2020 paper distinguishes autistic burnout from occupational burnout on multiple dimensions: autistic burnout features skill regression and increased sensory sensitivity that occupational burnout does not, the precipitants are different (prolonged camouflaging vs work overload), and the recovery requires different conditions (reduction in social and sensory load rather than vacation or job change). The two can co-occur but are not the same phenomenon.
Take the Adult Autism Test
If high camouflaging is part of your experience, the LBL Adult Autism Test (RAADS-14) may give you useful information. The RAADS-14 was specifically designed to flag adult autism in people whose presentation may not match older male-skewed diagnostic criteria, and its self-report format often detects autism in camouflaging adults whom in-person assessment misses.
Run the RAADS-14 in your browser
14 items, 5–7 minutes. Returns total score, three subscale scores (Mentalizing / Social Anxiety / Sensory), severity band, and a presentation archetype. Browser-local: no transmission, no storage, no accounts. Includes a Cassidy 2014 care-aware result framing for adults reaching late-diagnosis support.
Start the test →Note: a high CAT-Q-style camouflaging pattern combined with a positive RAADS-14 is one of the more common late-diagnosis pathways. Comprehensive clinical evaluation by a clinician familiar with adult autism (and ideally with camouflaging in adult women if applicable) is the next step after a positive screen.
Frequently asked questions
What is autism camouflaging?
Autism camouflaging (also called masking) describes the conscious or unconscious strategies autistic people use to hide, suppress, or compensate for autistic traits in social situations to appear more neurotypical. It is measured by the Camouflaging Autistic Traits Questionnaire (CAT-Q; Hull 2019), which identifies three components: compensation (active strategies to manage social difficulty), masking (hiding autistic traits), and assimilation (trying to fit in).
Is camouflaging the same as masking?
The terms are often used interchangeably, but in Hull 2019’s three-factor model masking is one component of camouflaging (specifically: hiding autistic traits or portraying a non-autistic persona), alongside compensation and assimilation. In community use, masking is more common and broader; camouflaging is the academic umbrella term and is more common in research literature.
What is the CAT-Q?
The CAT-Q (Camouflaging Autistic Traits Questionnaire) is a 25-item self-report measure developed by Hull et al. and published in the Journal of Autism and Developmental Disorders in 2019. Items are rated 1 (strongly disagree) to 7 (strongly agree); total scores range 25–175. The measure has three subscales: compensation (9 items), masking (8 items), and assimilation (8 items). It is freely available for non-commercial research and clinical use.
Why do autistic women camouflage more than men?
Most studies report higher CAT-Q scores in autistic women than autistic men, although a recent 2025 study by Bertelli and colleagues found no sex differences in a clinical sample. Proposed reasons include stronger social pressure on women to be socially fluent, earlier socialization into impression management, and selection effects (autistic women who do not camouflage may be diagnosed earlier in childhood while those who camouflage successfully reach adulthood undiagnosed). The pattern is reversed only in clinical samples where diagnosis itself selects for higher trait severity in men.
Is camouflaging bad for mental health?
Cross-sectional studies consistently show camouflaging is associated with elevated anxiety, depression, suicidality, and autistic burnout. However, a 2025 longitudinal study by van der Putten and colleagues complicates the simple causal story: among 332 Dutch autistic adults followed over 2 years, those with high initial camouflaging actually showed decreased mental health difficulties, while those with low initial camouflaging showed increases. The relationship is real but more complex than "camouflaging causes harm", and may depend on context, autonomy, and reasons for camouflaging.
Does camouflaging affect autism diagnosis?
Yes. Standard diagnostic instruments rely on observed autistic features, and camouflaging can effectively hide these features during assessment. The camouflaged behaviors include eye contact rehearsed in mirrors, scripted social responses, hidden stimming, and suppression of special interests when speaking with clinicians. A 2025 narrative review identifies camouflaging as one of the primary reasons adult women without intellectual disability are missed in autism evaluation.
Can camouflaging cause autistic burnout?
Yes. Autistic burnout, characterized by chronic exhaustion, loss of skills, and reduced tolerance to stimulus, is increasingly understood as a consequence of prolonged camouflaging, particularly when sustained over years without adequate recovery. The 2020 Raymaker et al. paper (Autism in Adulthood) identifies long-term masking as a primary precipitant. Many late-diagnosed adults present to clinical services after a burnout episode reveals camouflaging that had previously been hidden even from the autistic person themselves.
Can I stop camouflaging?
The unmasking process is gradual and typically partial. Reducing camouflaging is generally beneficial when paired with environmental change (working in autism-friendly environments, choosing accepting social contexts) but can be socially costly without those supports. Most autistic adults who unmask report doing so selectively, by domain (unmasking with close friends and family while continuing some camouflaging professionally) rather than abruptly across all contexts. Therapy with neurodiversity-affirming clinicians is often helpful.
This entry is educational and is not medical, psychological, or professional advice. The CAT-Q is a research instrument, not a diagnostic tool for autism. Adults who suspect they may be autistic, with or without significant camouflaging, should consider consulting a psychologist, psychiatrist, or neurodevelopmental specialist with adult ASD experience, ideally one familiar with camouflaging and the female autism phenotype. See our editorial policy and disclaimer for the broader framework.
