Q: What is 'masking' in autism?

Masking (or camouflaging) is a strategy used by many autistic people to appear neurotypical. It involves mimicking social cues, suppressing natural behaviors like stimming, and 'performing' socially expected responses. While it helps navigate social situations, it is extremely exhausting and often leads to burnout.

What our tests measure

Based on validated instruments used in clinical and research settings worldwide, aligned with DSM-5 diagnostic criteria.

Social communication: How you process social cues, navigate conversations, read facial expressions, and understand the unspoken rules that govern social interaction.
Sensory processing: Sensitivity to sounds, lights, textures, tastes, and smells. Many autistic people experience hyper- or hypo-sensitivity to input that others barely notice.
Routines and patterns: The need for structure, predictability, and consistency. Unexpected changes to established routines can cause significant distress.
Focused interests: Intense, deep engagement with specific topics, often with encyclopedic knowledge. A source of joy, identity, and expertise for many autistic people.

Important: These screening tools are not diagnostic instruments. A formal autism diagnosis can only be made by a qualified healthcare professional after a comprehensive evaluation.

Understanding autism

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects how people perceive the world and interact with others, and many autistic people remain undiagnosed.

Social communication: Differences in processing social cues, eye contact, and conversational flow.
Behaviors and interests: Focused interests, preference for routine, and unique sensory processing.
Neurodivergent strengths: Pattern recognition, deep focus, systematic thinking, and attention to detail.

After your screening

Understanding your traits can be a powerful moment of self-discovery. Consider seeking a formal evaluation if you experience:

Ongoing social exhaustion or feeling like you're "acting"
Significant sensory sensitivities to noise, light, or touch
A lifelong feeling of being "different" or on a different wavelength
Extreme difficulty with changes in routine or environment

A formal diagnosis provides access to accommodations, support, and deeper self-understanding.

Frequently asked questions

What is Autism Spectrum Disorder? +

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by differences in social communication, sensory processing, and patterns of behavior. It is considered a spectrum because it presents differently in each individual.

Which autism test should I take? +

If you're short on time, start with the AQ-10 (2-3 minutes). For a comprehensive assessment, take the AQ-50 (10-15 minutes). If you're an adult who suspects you may be autistic, the RAADS-R is the most thorough option (15-20 minutes). For parents screening toddlers aged 16-30 months, use the M-CHAT-R.

Can adults be diagnosed with autism? +

Yes, many adults are now being diagnosed later in life as awareness grows. Many people develop "masking" behaviors to blend in, which can delay diagnosis for decades, especially for women and people of color. Our AQ-10, AQ-50, and RAADS-R are all designed for adult self-assessment.

Is this a clinical diagnosis? +

No. These are peer-reviewed screening tools used to identify autistic traits, but they are not diagnostic instruments. A formal diagnosis can only be made by a qualified healthcare professional. However, self-identification is widely respected in the neurodivergent community.

What is "masking" in autism? +

Masking is a strategy used by many autistic people to appear neurotypical. It involves mimicking social cues, suppressing natural behaviors like stimming, and "performing" socially expected responses. While it helps navigate social situations, it is extremely exhausting and often leads to burnout.
