Making Therapy More Accessible Without Waiting for a Diagnosis

A client tells you that the overhead lights make it difficult to concentrate. Do you need an autism diagnosis before turning them off?

A client says they understand complex questions better when they can see them in writing. Do you need documentation before providing written information?

A client tells you that eye contact makes it harder to listen. Do you need to determine exactly why before allowing them to look somewhere else?

These examples sound simple when stated this way. Yet in clinical practice, we can become so focused on understanding why a client has a particular need that we overlook an equally important question:

What would help this person participate more fully in therapy?

Research involving autistic adults consistently points toward the importance of individualized care, communication access, sensory considerations, environmental fit, autonomy, and respect for the person’s own priorities. Curnow et al. (2023), for example, concluded that mental-health interventions for autistic adults should take account of individual preferences, communication differences, sensory and thinking preferences, and environmental adaptations rather than focusing exclusively on changing the individual.

This does not mean assuming every preference is related to autism. It means treating information about how a client communicates, processes information, experiences the environment, and regulates themselves as clinically relevant information. Sometimes the most appropriate intervention is not teaching the client to tolerate therapy exactly as we traditionally provide it.

Sometimes it is changing how we provide therapy.

Accommodation Is Not a Reward for Diagnosis

We often think about accommodations in formal terms. A person receives a diagnosis. Documentation is produced. An accommodation is approved.

That process may be necessary in schools, workplaces, disability services, and other systems. But many changes within counseling are simply matters of individualized clinical practice. Nicolaidis et al. (2015) interviewed autistic adults and people who supported them in healthcare settings and found that successful interactions were influenced not only by the autistic person’s characteristics, but by provider behavior and the surrounding environment. Helpful provider practices included allowing written communication, using accessible language, making accommodations, and avoiding incorrect assumptions about the individual.

If a client thinks more clearly with softer lighting and changing the lighting is feasible, we can change it. If a client processes questions more effectively one at a time, we can ask one at a time. If written information helps them retain what we discussed, we can provide it. If greater predictability reduces the amount of cognitive energy spent trying to determine what is expected, we can make the process more predictable.

None of those choices requires us to conclude:

“This person is autistic.”

They require us to notice:

“This helps this client participate.”

That leads to one of the central principles of this series: Accommodation does not require diagnostic certainty.

Communication: Make the Implicit More Explicit

Counseling relies heavily on language. And counseling language can be surprisingly ambiguous.

We ask:

“How does that sit with you?”

“What comes up for you?”

“Where do you want to go with that?”

“Tell me more.”

For some clients, these questions create useful space. For others, they create another task:

Figure out what the therapist actually wants me to answer.

Nicolaidis et al. (2015) found that communication difficulties varied substantially among autistic adults and that participants specifically recommended accessible language and less vague questioning. Some participants described difficulty responding when questions were abstract or interpreted literally.  Their participants also specifically recommended that providers avoid vague or overly open-ended questions and respect individualized communication needs.  Greater specificity can help. Instead of:

“How did that make you feel?”

we might ask:

“When that happened, did you notice an emotion, a physical sensation, a thought, or something else?”

Instead of:

“How was your week?”

we might ask:

“Since we met last Tuesday, what has been the hardest part of your week?”

This does not mean eliminating open-ended questions. It means noticing whether our language is facilitating reflection or creating an unnecessary communication barrier. Fung (2026) similarly describes neurodiversity-informed communication as grounded in mutual respect, autonomy, clear and concrete communication, accommodation of communication preferences, and providing information in forms that fit the individual.  The goal is not to create one universal “autism communication style.”

There is no such thing.

The goal is to become less attached to the assumption that our preferred communication style is automatically the most therapeutically useful one.

Processing Time: Stop Asking the Next Question

Consider a familiar moment in therapy.

You ask a question.

The client pauses.

You wait.

They are still thinking.

So you try to help:

“I mean, maybe another way of thinking about it would be…”

The client continues processing.

You offer another version.

“Or I guess what I’m really asking is…”

Now the client is no longer processing one question.

They are processing three.

Nicolaidis et al. identified slow processing speed as one factor that could affect healthcare interactions for autistic adults, alongside communication differences and sensory demands.  Fung (2026) also identifies delayed processing and response time as something providers should accommodate when it is relevant to the individual.  A simple intervention may be:

“Would you like some time to think about that?”

Or:

“I don’t mind the silence. Take the time you need.”

Some clients may benefit from seeing a complex question in writing. Others may appreciate receiving certain questions before the appointment or having important information summarized afterward. And some will prefer none of those things. The principle is:

Ask clients how they process information best, and take that information seriously.

Silence Does Not Necessarily Mean Disengagement

Counselors are trained to observe behavior. That is important. But behavior does not always tell us what is happening internally. Silence can mean avoidance. It can mean dissociation. It can mean discomfort. It can mean anger. It can mean reflection. It can also mean:

“I am still figuring out my answer.”

Looking away does not necessarily mean disengagement. Movement does not necessarily mean inattention. A less expressive face does not necessarily mean an absence of emotion. Fluent speech does not necessarily mean that processing is effortless.

Wilson et al. (2025), in qualitative interviews with autistic adults seeking mental-health support, identified recurring misunderstandings between autistic people and providers. Their themes emphasized communication, being understood as an individual, support for self-understanding, empowerment, trust, and psychological safety.  Curiosity is therefore often more useful than immediate interpretation. Instead of deciding what a behavior means, ask.

“I notice you’re quiet. Are you still thinking about the question, would you like me to clarify it, or is something else happening?”

The client has access to information about their internal experience that observation alone cannot provide.

Sensory Environment: The Therapy Room Is Part of the Intervention

Therapy does not happen in a sensory vacuum. Consider everything a client may be processing while sitting across from us:

the overhead lighting;

the hum of the air conditioning;

voices in the hallway;

a ticking clock;

traffic outside;

a scented candle;

the texture of the chair;

the room temperature;

visual clutter;

our voice;

our movement;

and the emotionally demanding conversation we are asking them to have.

For some clients, most of that fades into the background. For others, it does not. Nicolaidis et al. (2015) found that sensory sensitivities could directly interfere with successful healthcare interactions. One participant described bright lights, white walls, crowded waiting areas, and background conversation as so cognitively demanding that it became difficult to process what the provider was saying or communicate concerns.

Participants also reported more positive experiences in quieter environments with natural lighting or private waiting spaces.  This matters clinically because a client who is devoting substantial cognitive resources to managing the environment has fewer resources available for therapeutic work. That can be easy to misinterpret. We may think:

They seem distracted.

They are unusually irritable.

They are avoiding the topic.

They cannot regulate today.

Sometimes those interpretations will be accurate. But another question deserves consideration:

“Is there anything about this room that makes it harder for you to think or concentrate?”

Possible adaptations might include reducing lighting when feasible, limiting unnecessary background noise, allowing a different seating position, avoiding unnecessary scents, permitting movement or fidgeting, or considering telehealth when the client’s own environment works better for them. The principle is broader than any individual accommodation:

Before interpreting difficulty as pathology, consider the environment in which the difficulty is occurring.

This person-environment emphasis is also central to neurodiversity-informed models, which argue that disability and distress can emerge partly from a mismatch between the individual and an environment that does not accommodate neurological differences.

Predictability: Reduce Unnecessary Uncertainty

Therapy necessarily contains uncertainty. We cannot, and should not, eliminate all of it. But there is a difference between therapeutically meaningful uncertainty and uncertainty that exists simply because no one explained what would happen. Some autistic adults in Nicolaidis et al. (2015) described positive healthcare experiences when providers communicated beforehand about who would be present, what the process would involve, and approximately how long it would take.  In therapy, that might sound like:

“I’m going to spend the first part of today asking questions about your history. Then we’ll talk about what you’d like help with and what our work might look like.”

Before an intervention:

“I’m going to explain the exercise first. You don’t need to do anything while I explain it. Then you can ask questions before we decide whether to try it.”

Before a change in routine:

“Next session I want to spend some time reviewing your treatment plan, so the session will be a little different from what we normally do.”

None of this eliminates therapeutic challenge. It eliminates unnecessary guessing. Instead of automatically interpreting a desire for predictability as pathological rigidity, ask:

“What does predictability make possible for this client?”

If clarity allows the client to engage more deeply, predictability may support treatment rather than interfere with it.

Performance Is Not the Same as Capacity

A client may successfully complete an intervention and still pay an unsustainable price for doing it. They may complete a difficult trauma-processing session and be unable to function for the remainder of the day. They may attend a social event successfully but require extensive recovery afterward. They may appear composed through an entire appointment while using substantial effort to manage sensory input, communication demands, and emotional processing.

Research on autistic burnout helps illustrate why outward performance may not capture the entire picture. Ali et al. (2026) explored burnout experiences among adults diagnosed with autism earlier and later in life. Participants described depletion of mental and physical energy, difficulty processing sensory information, reduced everyday functioning, increased need for withdrawal or sensory rest, and a sense that their minds and bodies had become overwhelmed by cumulative demands. That makes two questions especially important:

“What did doing it cost you?”

and

“What happened afterward?”

Being able to perform a task does not necessarily tell us whether the task is sustainable. That distinction matters when evaluating progress.

Keep the Intervention. Question the Assumptions.

Neurodiversity-affirming practice does not require abandoning established psychotherapy. Autistic adults may benefit from CBT, trauma-focused treatment, behavioral activation, emotion-regulation interventions, interpersonal work, mindfulness, and other approaches.

The evidence base is not yet strong enough to say exactly which autism-specific adaptations should always accompany a particular therapy. Curnow et al. (2023) found that evidence regarding psychological therapies in autistic adults remains heterogeneous and that there is insufficient research establishing which adaptations should be used and how.

That is an important limitation.

It means we should not pretend there is a standardized checklist of modifications that every autistic client requires. Instead, we can examine the assumptions built into how we deliver treatment. For example:

Eye contact indicates engagement.

Does it?

Or does this client listen better when they are not simultaneously managing eye contact?

More social interaction is inherently healthier.

Is it?

Or is the actual goal meaningful connection at a sustainable level?

Flexibility is always preferable to routine.

Is it?

Or does a particular routine provide regulation, predictability, efficiency, or pleasure?

Discomfort should always be challenged.

Sometimes.

But what kind of discomfort?

Successful completion demonstrates capacity.

Not necessarily.

It demonstrates that the client completed the task.

Curnow et al. argue that interventions should be matched to autistic adults’ individual preferences, communication differences, sensory and thinking preferences, and environments.  So perhaps the most useful guiding statement is:

Keep the intervention when it is clinically appropriate. Question the assumptions. Adapt the delivery.

Accommodation and Avoidance Are Not the Same Thing

This is where we need to be especially careful. Counselors are appropriately concerned about reinforcing avoidance. If a client finds something uncomfortable, should we reduce the demand or help them learn to tolerate it?

The literature we reviewed does not provide a simple rule for answering that question. What it does support is the need to understand what is driving the behavior before deciding what the behavior means. Kildahl et al. (2021), in their systematic review of pathological or extreme demand avoidance in children and adolescents, found substantial conceptual and methodological uncertainty. They note that demand-avoidant behavior may be related to anxiety, trauma, sensory factors, uncertainty, perceived threat, or contextual demands, and caution against allowing a descriptive label to become an explanation that obscures underlying processes.  They also emphasize that contextual and transactional factors matter and that the demands themselves have rarely been adequately examined.  Although this review concerns children and adolescents and is not a psychotherapy treatment study, the clinical reasoning it supports is useful:

Avoidance describes what someone did. It does not, by itself, tell us why they did it.

Suppose a client avoids a crowded store. One possibility is that anxiety predicts catastrophe:

“Everyone will notice me.”

“I’ll embarrass myself.”

“Something terrible is going to happen.”

If fear-based avoidance is maintaining an anxiety disorder, exposure-based work may be appropriate.

Now imagine another client saying:

“There are six conversations happening, music overhead, carts moving unpredictably, fluorescent lights, people brushing against me, and after twenty minutes I can’t process anything.”

That is a different formulation. Environmental adaptation may be appropriate when unnecessary sensory, communication, or accessibility barriers are contributing to distress. And both processes can coexist. An autistic person can also have an anxiety disorder. So the clinically relevant question is:

“What process are we actually treating?”

The goal is not to choose “accommodation” or “exposure” as competing ideologies. The goal is to understand the function of the difficulty well enough to select the right intervention.

Goals Should Belong to the Client

Another useful question is:

“Why is this a treatment goal?”

Consider eye contact. If a client says:

“I want to become more comfortable making eye contact because it matters to me,”

that is one conversation.

If the goal exists because the counselor assumes that conventional eye contact represents healthier social functioning, that is another.

The same applies to socializing.

Is the client lonely and seeking deeper relationships?

Or are we increasing social activity because we assume that more socializing automatically equals better functioning?

What about routines?

Is the routine harming the client or interfering with something they value?

Or does it simply look unusual?

Dwyer (2022) argues that neurodiversity approaches should attend to the autistic person’s own strengths and difficulties while also examining environmental context rather than defining success exclusively as movement toward neurotypical behavior.  Leadbitter et al. (2021) similarly argue for moving away from normative intervention goals and toward autistic priorities, autonomy, coping, well-being, and environmental goodness-of-fit.  This does not mean that distress or impairment should be ignored. It means distinguishing:

What is causing the client suffering?

from:

What simply makes the client different?

Those can overlap. They are not the same thing.

Difference ≠ pathology.

Acceptance Matters Too

Clinical adaptation is not only about lights, written instructions, or appointment structure. It is also about the stance we take toward the person. Cage et al. (2018) found that autism acceptance from others and personal acceptance were associated with mental-health outcomes in autistic adults. Greater acceptance was associated with lower depression, and the authors also found evidence suggesting that camouflaging may relate to increased depressive symptoms.

Davies et al. (2024), in a systematic review of autistic identity research, similarly found that external acceptance and support were associated with more positive autistic identity, and positive autistic identity was associated with better mental health and well-being. That does not mean therapy should never challenge behavior. It means the therapeutic aim should not automatically become:

“How do we make this person appear less autistic?”

Dwyer (2022) notes that masking and camouflaging have been associated in the literature with exhaustion, burnout, anxiety, depression, stress, reduced well-being, and suicidality, while also correctly cautioning that these findings do not establish simple causality.  So the goal should not be forced authenticity either. It should be greater awareness, safety, choice, and agency.

Ask Rather Than Assume

Perhaps the simplest clinical adaptation is still the most important:

Ask.

You might ask:

“What makes therapy easier for you to participate in?”

“Is there anything about this room that makes it harder to concentrate?”

“Would you rather I ask one question at a time?”

“Would it help to have that in writing?”

“Do you need more time before answering?”

“How do you know when you are becoming overloaded?”

“What do you usually need in order to recover?”

“When you leave therapy, how much energy do you have left?”

“Are we working at a pace that feels challenging but sustainable?”

Wilson et al. (2025) found that autistic adults described better mental-health care in terms of being communicated with effectively, understood as individuals, supported in understanding themselves, empowered, and treated in ways that created trust and psychological safety. Not every client will immediately know what helps. That matters too. Someone who has spent years asking:

“How do I make myself fit this environment?”

may have had very little opportunity to ask:

“How could the environment fit me better?”

Learning that can itself become part of therapy.

What If the Client Is Not Autistic?

The adaptations described here are not exclusive to autism. A nonautistic client may process information more effectively in writing. A trauma survivor may benefit from predictability. Someone with ADHD may benefit from reduced distractions. A client with auditory-processing differences may prefer written information. Someone experiencing depression, grief, or exhaustion may temporarily need a slower pace.

If an adaptation is clinically appropriate, feasible, ethical, and improves participation, we do not necessarily need a diagnostic explanation before considering it.That is why the central question remains:

“Does this help this particular person?”

Neurodiversity-affirming care is not a checklist of accommodations. It is individualized care informed by the recognition that people differ in how they process, communicate, regulate, and participate.

What Can I Do Differently on Monday?

You do not need to redesign your entire practice.

Start with one question:

“Is there anything about how I communicate, the environment we’re in, or the way we structure therapy that makes it harder for you to participate?”

Then listen.

Perhaps nothing needs to change.

Perhaps the client wants you to stop asking three questions at once.

Perhaps they want the lights dimmer.

Perhaps they want written instructions.

Perhaps they need more warning before switching topics.

Perhaps they need more time after emotionally demanding work.

Perhaps something you had interpreted as resistance has a completely different explanation.

The goal is not to create “autism therapy.”

The goal is to make this therapy accessible to this person.

The Bottom Line

You will not always know whether autism is part of a client’s clinical picture.

Some clients will eventually receive a formal diagnosis.

Some will not.

Some will self-identify as autistic.

Some will explore the possibility and decide another explanation fits better.

Therapy does not have to stop while that question is being answered.

We can communicate more clearly.

We can allow processing time.

We can consider sensory environments.

We can provide predictability.

We can evaluate the cost of functioning, not merely whether functioning occurred.

We can distinguish environmental barriers from fear-based avoidance by understanding the function and context of the behavior.

And we can ask whether our treatment goals are reducing suffering and increasing meaningful participation—or simply encouraging someone to appear more typical.

None of that requires diagnostic certainty.

It requires individualized counseling.

Screening ≠ diagnosis.Difference ≠ pathology.Accommodation does not require diagnostic certainty.

And perhaps one more principle belongs beside them:

Before asking the client to adapt to therapy, ask whether therapy can adapt to the client.
