Before You Start

As you work through the checklist, try to think about patterns across your life, rather than whether something has happened once or twice.

You might also think about:

• whether these experiences have been present since childhood, even if they looked different then
• whether you experience them in more than one environment
• how much effort you use to manage certain situations
• whether other people see the effort involved
• whether you have consciously learned ways to fit into social situations
• whether particular environments make things easier or harder
• whether these experiences affect your everyday life, relationships, work, study or wellbeing
• whether you have strengths or strategies that help you manage areas you find difficult

Some adults have spent many years adapting to expectations around them. This can sometimes make autistic characteristics less obvious to other people.

Adult Autism Checklist

Social Communication & Connection
​
​You may:
☐ find it difficult to know how to start, continue or end a conversation
☐ find small talk confusing, uncomfortable, tiring or unnecessary
☐ prefer conversations about specific subjects rather than general social conversation
☐ find it difficult to know when it is your turn to speak
☐ accidentally interrupt or speak for longer than you intended when discussing something important to you
☐ need extra time to work out what you want to say
☐ find group conversations difficult to follow
☐ find it easier to communicate one-to-one than in a group
☐ feel unsure about unwritten social rules
☐ consciously study how other people behave so you know what to do
☐ rehearse conversations before they happen
☐ replay conversations afterwards and wonder whether you said the right thing
☐ find it difficult to tell when someone is joking, being sarcastic or implying something indirectly
☐ interpret language literally at times
☐ find it difficult to understand what another person expects unless they explain it clearly
☐ prefer direct, specific communication
☐ find friendships difficult to begin or maintain
☐ have a small number of close relationships rather than a large social circle
☐ enjoy spending significant amounts of time alone
☐ feel lonely or disconnected even when you are around other people
☐ have often felt that other people seem to understand social situations instinctively while you have had to learn them

---

Communication Style

You may:
☐ communicate more comfortably in writing than face-to-face
☐ need time to process spoken information before responding
☐ find vague instructions difficult to interpret
☐ prefer people to say exactly what they mean
☐ give detailed explanations when discussing something important to you
☐ have been told that you sound overly direct, formal, blunt or factual even when you did not intend to
☐ find it difficult to change your communication style depending on the situation
☐ use familiar phrases or ways of explaining things repeatedly
☐ find telephone calls particularly difficult or prefer to know what a call will be about beforehand
☐ prepare what you are going to say before appointments, meetings or social interactions
☐ find unexpected questions difficult to answer immediately
☐ know what you want to communicate but sometimes find it difficult to put it into words

---

Sensory Differences

You may experience sounds, lights, textures, smells, movement, temperature or other sensations differently from people around you.

You may:
☐ be particularly sensitive to certain sounds
☐ notice background noises that other people seem able to ignore
☐ find sudden or unpredictable noises distressing or overwhelming
☐ find fluorescent, bright or flickering lighting uncomfortable
☐ prefer dimmer or more predictable lighting
☐ find particular clothing fabrics, seams, tags or textures difficult to tolerate
☐ strongly dislike particular food textures, tastes or smells
☐ notice smells that other people do not seem to notice
☐ find busy shops, shopping centres, offices, public transport or crowded places overwhelming
☐ become exhausted after spending time in highly stimulating environments
☐ avoid particular environments because of their sensory demands
☐ seek particular textures, movement, pressure, sounds or other sensory experiences
☐ use repetitive movement or sensory activities because they feel comfortable or help you regulate
☐ need time in a quiet or familiar environment after sensory overload
☐ find it difficult to concentrate when there are competing sounds, movement or visual information around you

Sensory preferences and needs vary considerably between people. Being sensitive to one type of sensory input does not mean you will be sensitive to everything.

---

Routines, Predictability & Change

You may:
☐ feel more comfortable when you know what is going to happen
☐ prefer familiar routines
☐ have particular ways you like to complete everyday activities
☐ find unexpected changes stressful or difficult to process
☐ need time to adjust when plans change
☐ prefer to know details before going somewhere unfamiliar
☐ research new places before visiting them
☐ plan journeys, appointments or events carefully
☐ prefer using familiar routes, shops, foods or services
☐ find last-minute invitations difficult even when you would otherwise enjoy the activity
☐ become unsettled when someone changes an arrangement without warning
☐ find transitions between activities difficult
☐ rely on routines to reduce the amount of planning and decision-making required during the day
☐ feel significantly more comfortable when expectations are clear

Having routines is not inherently a problem. Routines can be useful and supportive. The relevant question is how predictability, uncertainty and changes affect you.

---

Focused Interests & Attention

You may:
☐ develop very strong interests in particular subjects
☐ spend substantial amounts of time learning about topics that interest you
☐ enjoy collecting, categorising or organising information
☐ remember detailed information about subjects that interest you
☐ become deeply absorbed in an activity or interest
☐ find it difficult to stop an interesting activity to move onto something else
☐ enjoy talking in detail about particular subjects
☐ return to particular interests throughout your life
☐ use your interests as a source of enjoyment, comfort or connection
☐ have developed significant knowledge or skills through your interests
☐ notice details or patterns that other people may overlook

Focused interests can be an important source of enjoyment, expertise, identity, connection and strength.

---

Planning, Organisation & Executive Function

You may:
☐ know what you need to do but have difficulty getting started
☐ find tasks with many steps difficult to organise
☐ become overwhelmed when several things need to be done at once
☐ find switching between tasks difficult
☐ lose track of time when absorbed in something
☐ find it difficult to estimate how long a task will take
☐ rely heavily on calendars, lists, reminders or routines
☐ struggle to prioritise when several tasks seem equally important
☐ put off tasks that feel unclear or overwhelming
☐ find unexpected interruptions make it difficult to return to what you were doing
☐ need recovery time after completing demanding activities
☐ find everyday administration, appointments or household responsibilities take more effort than other people might expect
☐ function well when there is external structure but find self-directed tasks much harder

Executive-function difficulties are not unique to autism and can also occur with ADHD and for many other reasons.

---

Masking & Camouflaging

Some autistic adults consciously or unconsciously adapt their behaviour in social situations to try to fit in or meet other people's expectations.

You may:
☐ copy other people's facial expressions, gestures or ways of speaking
☐ observe other people closely to work out how you are expected to behave
☐ rehearse conversations before social situations
☐ prepare responses to questions you expect people to ask
☐ force yourself to make eye contact even when it feels uncomfortable or distracting
☐ suppress movements or behaviours that help you feel comfortable
☐ hide sensory discomfort from other people
☐ avoid talking about interests because you worry other people will judge you
☐ consciously change your personality or behaviour depending on who you are with
☐ feel as though you are performing a role in social situations
☐ appear socially confident while internally working very hard to manage the interaction
☐ feel exhausted after socialising even when the experience appeared to go well
☐ need substantial time alone after work, study or social activities
☐ feel that very few people know the version of you that feels most natural

Masking can make autistic characteristics less visible to other people. It can also mean that the effort involved in navigating everyday situations is underestimated.

---

Work, Study & Everyday Responsibilities

You may:
☐ perform well at the actual work or study task but struggle with the surrounding social or organisational demands
☐ find open-plan workplaces difficult because of noise, lighting or interruptions
☐ prefer clear instructions and defined expectations
☐ find unclear workplace expectations stressful
☐ struggle when priorities change without warning
☐ find meetings or group discussions difficult to follow
☐ need time to process information before responding
☐ find networking or workplace social events particularly demanding
☐ work very hard to appear comfortable or confident at work
☐ become exhausted from maintaining your work or study responsibilities
☐ find balancing work or study with cooking, cleaning, appointments and other everyday tasks difficult
☐ perform much better in environments that are predictable and suited to your sensory and communication needs

---

Daily Living & Independence

Autistic adults can have very different support needs.

You may:
☐ find preparing meals difficult because of planning, sensory or organisational demands
☐ rely on a limited range of familiar foods
☐ find shopping overwhelming
☐ struggle to keep up with cleaning, laundry or household routines
☐ find personal care activities difficult because of sensory experiences
☐ have difficulty organising appointments or paperwork
☐ find unfamiliar travel or public transport stressful
☐ need support with some everyday activities despite being highly capable in other areas
☐ find changes to your home environment particularly difficult
☐ need more time than expected to complete everyday activities
☐ develop detailed systems to make everyday tasks manageable
☐ find that everyday responsibilities become much harder during periods of stress, change or exhaustion

Needing support in one area does not cancel out your strengths or independence in another.

---

Energy, Overwhelm & Recovery

You may:
☐ become overwhelmed when too many demands build up
☐ need substantial time alone to recover after social activities
☐ feel exhausted after spending time in noisy, busy or unpredictable environments
☐ have difficulty speaking, thinking or making decisions when overwhelmed
☐ need quiet, reduced demands or familiar activities to recover
☐ find your ability to manage everyday activities changes depending on how much energy you have available
☐ cope well for a period and then feel completely depleted afterwards
☐ find several small demands become overwhelming when they occur together
☐ need longer recovery periods than people around you seem to need
☐ notice that sensory, social and organisational demands all contribute to your overall energy levels

---

Looking Back at Childhood

Autism is a lifelong neurodevelopmental difference, although it may not be recognised until adulthood.

If you are considering whether you might be autistic, it can be useful to think about your childhood as well as your current experiences.

Looking back, you may remember:
☐ preferring solitary play or spending significant time alone
☐ having a small number of close friendships
☐ finding playground or group social situations confusing
☐ having strong or highly focused interests
☐ becoming deeply absorbed in particular topics or activities
☐ preferring routines or familiar activities
☐ finding changes particularly difficult
☐ being sensitive to sounds, clothing, foods, lights or other sensory experiences
☐ being described as shy, quiet, serious, intense, sensitive, particular or "in your own world"
☐ feeling different from other children without knowing why
☐ copying other children to work out how to fit in
☐ finding school socially exhausting even if you did well academically
☐ struggling with transitions between school years, classrooms or routines
☐ having strengths in some areas alongside significant difficulty in others
☐ needing substantial recovery time after school or social activities

You may not remember much about early childhood, and that does not mean you cannot explore an autism assessment.

Autism in Women & People Who Mask

Autism does not look the same in everyone.

Some autistic people may develop effective ways of observing, copying or learning social behaviours. This can make autistic characteristics less obvious to other people.

Some women and girls may be identified later because their autistic characteristics were overlooked, interpreted differently or masked.

An adult may have:

• friendships and relationships
• a career
• strong communication skills
• completed university or other study
• learned social rules
• developed effective coping strategies

​and still be autistic.

An assessment should consider the whole person and their experiences across their life, rather than relying on stereotypes about what an autistic person should look like.

What If I Recognise Myself in This Autism Checklist?

Recognising several experiences on this page does not automatically mean you are autistic.

It may, however, give you useful language for experiences you have found difficult to explain.

You might choose to:

Learn More About Autism
Reading reliable information from autistic people and evidence-based Australian sources can help you understand autism beyond common stereotypes.

Write Down Your Experiences
You may find it useful to record examples from:

• childhood
• school
• friendships and relationships
• work or study
• sensory experiences
• routines
• communication
• interests
• everyday living
• periods when demands became particularly difficult

Talk With Someone You Trust
A partner, parent, sibling, friend or another person who has known you for a long time may remember experiences you have forgotten.

Consider Speaking With a Health Professional
If you want to understand whether autism may explain your experiences, you can discuss this with an appropriately qualified health professional.

Consider a Formal Autism Assessment
Some adults decide they would like a formal diagnostic assessment. Others may initially want more information before deciding.

---

Do I Need an Autism Assessment?

There is no single answer.

Adults seek autism assessment for many different reasons.

You might want:

• a better understanding of yourself
• clarification about experiences you have had throughout your life
• a formal diagnosis
• information about your strengths and support needs
• evidence that may be relevant to particular supports or services
• help distinguishing autism from, or understanding it alongside, other conditions

A formal assessment is much more comprehensive than an online checklist.

It considers information about your development, current experiences, functioning, strengths and support needs and whether another explanation or combination of factors may better account for your experiences.

---

What Happens in an Adult Autism Assessment?

An adult autism assessment should look beyond whether you recognise individual autistic traits.

The assessment process may consider:

• your current experiences
• developmental history
• social communication
• behaviours and interests
• sensory experiences
• everyday functioning
• strengths
• support needs
• relevant health and developmental information
• other possible explanations for your experiences

Depending on the assessment and your circumstances, information from someone who knew you earlier in life may also be useful.

Belong Health provides Psychology assessments only. Our Psychology service does not provide ongoing psychological therapy.

If you are enquiring about an adult autism assessment, our team can discuss the assessment service available and whether it is appropriate for what you need.

---

Can I Get Support Without an Autism Diagnosis?

You do not necessarily need to wait for an autism diagnosis before seeking help with an area of everyday life that is difficult for you.

What support is appropriate will depend on:

• what you need help with
• the type of service
• clinician scope
• your individual circumstances
• whether you are accessing the service privately or through a funding program

For example, an Occupational Therapist may be able to work with functional needs affecting everyday activities without their role being to determine whether you are autistic.

Funding and eligibility requirements can be different from clinical support needs, so these should be considered separately.

---

Occupational Therapy for Autistic Adults

If you are autistic, already diagnosed, exploring whether you might be autistic, or simply need support with everyday functioning, Occupational

Therapy may be relevant depending on your individual needs.

OT can look at the interaction between you, the activities you need or want to do, and your environment.

Support may involve areas such as:

• daily living and independence
• sensory needs and environments
• routines and transitions
• planning and organisation
• executive-function demands
• energy and fatigue
• work and study
• community participation
• motor skills and coordination
• Assistive Technology
• environmental adaptations
• functional assessment

Occupational Therapy is not about making someone appear less autistic. The focus should be on meaningful activities, autonomy, participation and practical support.

Explore Occupational Therapy for Autistic Adults

---

Autism, ADHD or Both?

Autism and ADHD are different neurodevelopmental conditions, but some experiences can overlap and a person can also be both autistic and have ADHD.

For example, difficulties involving executive function, attention, organisation, sensory experiences or feeling overwhelmed cannot by themselves determine whether someone is autistic, has ADHD, both, or neither.

A checklist cannot reliably make that distinction.

If you are unsure what may explain your experiences, a comprehensive assessment can consider the broader picture rather than beginning with the assumption that there must be one particular diagnosis.

Autism Checklist for Adults: Frequently Asked Questions

Is there an autism checklist for adults?
Yes. An adult autism checklist can be used as an educational reflection tool to help you recognise experiences that may be associated with autism. A checklist alone cannot determine whether you are autistic.

How do I know if I might be autistic as an adult?
You may begin wondering about autism because of longstanding patterns involving social communication, sensory experiences, routines, focused interests, change or other aspects of everyday life. A formal autism assessment is required if you want a clinical diagnosis.

Can you become autistic as an adult?
Autism is a neurodevelopmental condition, so it does not suddenly develop in adulthood. However, some people are not identified as autistic until adulthood.

Can autism be missed in childhood?
Yes. Some people are diagnosed later in life. Their characteristics may have been less obvious, interpreted differently, masked or supported by routines and environments that made difficulties less apparent.

Can someone be autistic and good at socialising?
Yes. Autistic people have a wide range of communication and social abilities. Some people also consciously learn social rules or mask autistic characteristics.

Can you make eye contact and still be autistic?
Yes. Eye contact alone cannot determine whether someone is autistic. Some autistic people make eye contact comfortably, some find it uncomfortable or distracting, and others may consciously make eye contact because they have learned that it is socially expected.

Can you have friends and still be autistic?
Yes. Having friendships or relationships does not rule out autism.

Can you be autistic and have a successful career?
Yes. Autism does not determine a person's intelligence, education or career potential. Autistic adults have diverse strengths, abilities, occupations and support needs.

What is masking in autism?
Masking or camouflaging generally refers to adapting or concealing behaviours and characteristics in an effort to meet social expectations or fit into an environment. This may include copying social behaviours, rehearsing conversations or suppressing natural movements or responses.

Is masking more common in autistic women?
Research and clinical guidance recognise that masking may contribute to autism being overlooked, including in females. However, masking is not exclusive to women and can occur in autistic people of different genders.

What are sensory signs of autism in adults?
Some autistic adults experience sensory input differently. This might involve heightened or reduced responses to sound, light, touch, textures, smells, movement or other sensory information. Sensory differences alone do not establish an autism diagnosis.

Is needing a routine a sign of autism?
A preference for routine and predictability can be associated with autism, but many non-autistic people also prefer routines. It needs to be considered alongside a person's broader developmental history and experiences.

Are intense interests a sign of autism?
Focused or highly developed interests can be associated with autism. They can also be an important source of enjoyment, expertise, connection and identity. Having a strong interest by itself does not mean someone is autistic.

Can autism look like ADHD in adults?
Some experiences associated with autism and ADHD can overlap, particularly around executive function and everyday organisation. A person can also be both autistic and have ADHD. Assessment considers the broader pattern rather than relying on one characteristic.

What is Level 1 autism in adults?
Autism diagnostic levels relate to the level of support a person requires in areas considered during diagnosis. They should not be treated as a simple measure of how autistic someone is, and an online checklist cannot determine an autism support level.

Is this an adult autism test?
No. This page is an educational checklist for reflection. It is not a validated screening instrument, diagnostic test or substitute for a professional autism assessment.

Is there an online test that can diagnose autism?
An online test or checklist cannot provide a clinical autism diagnosis. Formal diagnosis involves assessment by appropriately qualified professionals.

Should I bring this checklist to an autism assessment?
You can use it to help organise examples or questions you want to discuss. An assessor will conduct their own assessment and will not determine a diagnosis based on this Belong Health checklist.

What if I cannot remember my childhood?
You can still discuss an assessment with an appropriately qualified professional. They can explain what information would be useful and how the assessment may proceed based on your individual circumstances.

Do my parents need to be involved in an adult autism assessment?
Not necessarily in every situation. Developmental information can be valuable, but an assessor should discuss what information is available and appropriate in your individual circumstances.

Do I need an autism diagnosis to see an Occupational Therapist?
Not necessarily. Occupational Therapy can address functional difficulties affecting everyday activities without the OT's role being to diagnose autism. Funding programs may have separate eligibility or evidence requirements.

Can Occupational Therapy diagnose autism?
An Occupational Therapy assessment of everyday function is different from an autism diagnostic assessment. If you are seeking a diagnosis, you need an appropriately qualified diagnostic professional or team.

Can I be autistic if nobody else notices?
Possibly. Other people's perceptions alone cannot determine whether you are autistic. Some people develop strategies that make their difficulties less apparent externally, while experiencing considerable effort internally.

What should I do if this checklist sounds like me?
You can learn more about autism, record examples from your life and decide whether you would like to speak with a health professional or explore a formal autism assessment. If particular functional difficulties are affecting your everyday life, you can also seek support for those needs.
