PDA-Informed Assessments

You know your child is different — but the pieces don't quite fit

You've probably already done your research. Maybe some of the autism criteria fit your child, but some don't. Your child might be socially engaged and surprisingly perceptive — but completely shut down the moment they feel controlled or pressured. Every demand, no matter how small — getting dressed, brushing teeth, leaving the house — can trigger what looks like a crisis. You may have been told your child is just defiant, given an ODD diagnosis, or handed behavior charts that have never once worked.

If any of that sounds familiar, a PDA-informed autism evaluation may be exactly what your family needs.

What is a PDA profile?

PDA stands for Pathological Demand Avoidance — though many clinicians prefer the term Persistent Drive for Autonomy, which better captures what is actually happening. PDA is a profile within the autism spectrum characterized by an intense, anxiety-driven need to resist everyday demands — not out of defiance, but because the nervous system experiences demands as a genuine threat.

Children with a PDA profile often:

• Resist ordinary demands intensely and consistently — including things they enjoy and want to do
• Use socially sophisticated strategies to avoid demands: negotiation, distraction, humor, or outright refusal
• Appear more socially aware than typical autism presentations, causing autism to be missed entirely
• Experience rapid mood swings driven by anxiety and a need for control
• Struggle with authority and social hierarchy
• Escalate quickly when avoidance strategies fail, with meltdowns that seem extreme relative to the trigger

PDA is not a standalone DSM-5 diagnosis in the U.S., but it is an increasingly recognized profile within autism. Identifying it can help to inform parenting approaches, school support, and therapeutic strategies.

Why PDA is so often missed

Because children with PDA often appear socially capable on the surface, autism is frequently overlooked. Because the demand avoidance looks like willful defiance, they are commonly labeled with ODD or conduct disorder. And because standard behavioral approaches — reward charts, clear expectations, consequences — often make things significantly worse, families can feel like they have already tried everything. They have not failed. The approach that works for most children simply is not the right approach for a child with a PDA profile.

What the evaluation includes

• Thorough parent interview with specific attention to demand avoidance patterns and history
• Review of prior evaluations, school records, and any previous diagnoses
• Comprehensive autism evaluation using gold-standard tools, interpreted through a PDA-informed lens
• Comprehensive written report with diagnostic conclusions and PDA-specific recommendations for home, school, and providers

Who this is for

• Your child resists everyday demands intensely, in ways that feel beyond typical oppositional behavior
• Standard autism evaluations have been inconclusive or felt incomplete
• Your child has been labeled defiant or behaviorally disordered — but that framing has never felt right
• Behavioral strategies have not worked, or have made things worse
• You suspect autism but your child does not fit the classic presentation
