PDA Testing & Assessment

Understanding the nervous system response behind demand avoidance — so your child can be supported, not misunderstood.

Pathological Demand Avoidance (PDA), also referred to as Pervasive Drive for Autonomy, is a profile of autism in which a child's nervous system responds to everyday demands as if they are a threat.

This is not about being oppositional or manipulative, even though it may sometimes be perceived that way. It is about anxiety and a need to maintain a sense of control.

The brain interprets

I'm being controlled → I'm not safe.

For children with a PDA profile, everyday requests (for example, "put your shoes on") can trigger a stress response similar to feeling unsafe. As a result, the body may shift into fight, flight, freeze, or fawn responses.

The evaluation

A Comprehensive & Individualized Evaluation

See Autism Testing & Assessment →

An evaluation for PDA is not a single test or a standalone diagnosis. Instead, it is a comprehensive evaluation that looks at how a child experiences and responds to everyday demands, particularly when anxiety is involved.

An assessment for PDA helps to explain:

Why a child struggles with demands that may seem simple to others

Whether avoidant behaviors are driven by anxiety and a need for control

How the child responds to expectations, transitions, and loss of autonomy

What strategies help the child stay regulated and engaged

This understanding helps guide support strategies.

Rather than focusing on labels alone, the evaluation aims to identify what actually helps your child stay regulated and engaged.

PDA is considered a profile within autism. Understanding this helps guide support strategies, rather than focusing on labels alone.

Space to Process

Room to ask questions and understand what this means for your child and your family.

The goal is to understand the 'why' behind your child's challenges and identify strategies that support regulation, autonomy, and engagement.

Many families report that the evaluation brings relief, language for advocacy, and a clearer path forward.

Consultation & Background Review

We begin with a comprehensive intake to discuss concerns, developmental history, and evaluation goals. I review relevant records to build a thorough foundation.

Individualized Testing

Each evaluation is tailored to the referral questions. I personally select, administer, and score all measures based on evidence-based practice and clinical judgment.

Careful Analysis & Interpretation

Results are carefully synthesized within the broader cognitive, academic, developmental, and emotional context. I examine patterns rather than relying on isolated scores.

Comprehensive Report & Feedback

You receive a feedback session, often the same week as testing. Children get a personalized feedback session too. A detailed written report follows within two weeks.

A Note on Strengths

Deeply creative, empathetic & fair.

Children with PDA often experience high levels of empathy and fairness sensitivity, and may be deeply affected by perceived injustice or imbalance.

Fun Fact ✦

Many children with PDA are highly creative and imaginative.

With rich pretend play, role-play, world-building, and original ideas — their imagination is a remarkable resource.
