When "I Won't" Is Actually "I Can't": Essential Insights Into PDA, Autism, and Anxiety

August 7, 2026 - 02:44

For years, Sarah Thompson watched her bright, creative daughter struggle with the simplest requests. "Put on your shoes," she would say, and the response was a flat, immovable "I won't." It looked like defiance, like stubbornness, or even a behavioral problem. But no amount of rewards, consequences, or gentle encouragement made a difference. The more Sarah pushed, the more her daughter shut down, often ending in a full-blown meltdown that left them both exhausted.

It was only after a long and frustrating diagnostic journey that Sarah, a special needs advocate, stumbled upon a concept that changed everything: Pathological Demand Avoidance, or PDA. It is a profile of autism that is often misunderstood, and it has nothing to do with the more common "fight, flight, or freeze" response. For Sarah's daughter, the real issue was not a refusal to comply, but a profound, panic-level anxiety triggered by the feeling of losing control. The "I won't" was actually a desperate "I can't."

PDA is not about being naughty or manipulative. It is a deeply rooted neurological response where everyday demands, even ones that seem trivial, feel like a threat to a person's autonomy. This includes not just direct instructions, but also the unspoken demands of daily life, like the expectation to eat at a certain time, the pressure of a scheduled activity, or even the implied demand of a question. The anxiety is so intense that the brain goes into survival mode, and the only way to cope is to resist.

Learning this reframed everything for Sarah. She stopped seeing a "difficult child" and started seeing a child in distress. The solution was not more discipline, but a different approach. It involved reducing the pressure, offering choices within a safe framework, and using humor and play to disguise demands. For example, instead of saying "Time for bed," she might say, "I bet I can beat you to the bathroom to brush our teeth." This subtle shift in control made the task feel less like a command and more like a game.

Sarah's story is not just about her family. It is a call to parents, teachers, and clinicians to look beyond the surface of behavior. When a child says "I won't," it is worth asking what they are really trying to communicate. For many with PDA, the answer is a desperate plea for help, a need for safety in a world that feels overwhelming and controlling. Recognizing that difference is the first step toward truly helping them, and it can turn a daily battle into a path of understanding and connection.
