In our previous blog, Is CBT the Best Therapy for a Highly Anxious Autistic Person?, we examined the research on CBT for autistic anxiety. Current evidence suggests that CBT can help some autistic people, particularly when adapted, but it does not establish CBT as the best approach for every highly anxious autistic person.
This raises an equally important question: what does autism-adapted CBT actually look like in practice?
Adaptation involves more than adding visual supports, incorporating focused interests or changing worksheets. Those providing therapy or support need to understand what is contributing to the person’s anxiety, how they recognise and communicate it, and whether the therapeutic approach itself is increasing pressure or cognitive load.
Across our clinical work with autistic children, adolescents and adults, we have found that how CBT is delivered can be as important as the therapeutic model itself. The following are some of the factors that may reduce the effectiveness or accessibility of conventional CBT, and the changes that may make therapy more relevant and supportive.
CBT may be less effective when it focuses on changing thoughts or avoidance without addressing what is contributing to the anxiety. It may help when someone anticipates a catastrophic outcome in a reasonably safe situation. However, anxiety may also reflect:
For example, an autistic employee who expects to be misunderstood may be responding to repeated experience rather than distorted thinking. Therapy may support communication and planning, but should not dismiss valid concerns.
Exposure may help when a person avoids a feared but sufficiently safe situation. It is not appropriate when the distress reflects sensory pain, ongoing bullying, unsafe treatment, or non-consensual physical contact. Repeated exposure to a genuinely painful or unsafe experience is unlikely to reduce anxiety and may intensify distress or undermine trust. Before using exposure, the therapist must determine whether the person is overestimating danger or accurately responding to an environment that is harmful or inaccessible.
For some autistic people with a PDA profile or pronounced demand-related distress, the way therapy or support is structured can itself increase anxiety. Externally imposed goals, compulsory tasks, rigid plans or pressure to demonstrate progress may reduce the person’s sense of autonomy. A person may want the outcome but find it difficult to engage when the process feels controlling or demanding. Even well-intended suggestions may become harder to act on once they are experienced as demands.
Research has not yet adequately established how anxiety therapies should be adapted for autistic people with PDA profiles. Current recommendations therefore draw substantially on clinical experience.
CBT can require considerable cognitive effort, including recalling events, identifying thoughts and emotions, completing monitoring tasks and generating alternative responses. When someone is already anxious or exhausted, these demands may increase cognitive load. Some autistic people may also become focused on finding the “correct” answer, trying to complete therapy perfectly or repeatedly analysing their thoughts.
CBT may create additional barriers when it relies heavily on spoken emotional language or assumes that the person can readily describe internal experiences. Emotional awareness can be developed within therapy rather than treated as a prerequisite. Anxiety may also be recognised through physical sensations, changes in speech or movement, urges to leave, reduced thinking capacity or changes in sensory tolerance.
A strategy that works in a quiet therapy setting may be difficult to access in a noisy classroom, an unpredictable workplace or another demanding environment. During high anxiety, an autistic person may also have reduced access to language, memory or flexible thinking.
CBT cannot compensate for environments that remain unsafe, inaccessible or unpredictable. Knowing a strategy does not mean the person can use it independently under conditions that continue to generate anxiety. Changes to the environment or to other people’s expectations may also be necessary.
CBT may help some autistic people, but it is not always the most appropriate response to anxiety. When CBT is used, it should recognise how autistic neurology, sensory experiences, communication, autonomy and environment may shape anxiety.
Effective support does not require an autistic person to tolerate avoidable distress or adapt to an inaccessible environment. It works with the person to identify what needs to change, whether that involves therapeutic strategies, practical support, accommodation or changes to the environment.
For many autistic people, the most helpful support communicates:
“Your brain is not wrong. Let’s work with it, not against it.”
