Autistic Rational Demand Avoidance

Is the PDA Autism profile helpful, or does it further pathologize Autistics?


PDA stands for Pathological Demand Avoidance, whereas RDA stands for Rational Demand Avoidance. I’ll explain what each means and why one approach may be more beneficial and accurate than the other.

The two key features of PDA are:

  1. Intolerance of uncertainty, and
  2. Extreme avoidance of basic demands.

This extreme avoidance extends to the basic demands of everyday living, not just the avoidance of unpleasant, difficult, specific anxiety-provoking or unappealing tasks.

Someone with a PDA profile may also have tremendous difficulty complying with their own self-imposed expectations and with doing things that they really want to do.

The distinctive features of a demand avoidant profile include:
  • Resists and avoids the ordinary demands of life.
  • Uses social strategies as part of avoidance, for example, distracting, giving excuses.
  • Appears sociable, but lacks some understanding.
  • Experiences excessive mood swings and impulsivity.
  • Appears comfortable in role play and pretence.
  • Displays obsessive behaviour that is often focused on other people.

People with this profile can appear excessively controlling and dominating, especially when they feel anxious. However, they can also be confident and engaging when they feel secure and “in control*”.

Anxiety quite often presents as controlling behaviour, irritability, and yes — avoidance.

It’s important to acknowledge that people with PDA have a hidden disability. Every neurodivergent person lives with an invisible disability. Just because we cannot directly see its impact does not mean it doesn’t exist.

But wait!

When clinicians or other adults use the term “in control”, what they are often insinuating is the person is being manipulative and controlling.

If we replace the word control with autonomy, agency, independence, self-determination, and respect — well, that paints a very different picture.

While autism comes with many assets and strengths, the lack of acceptance and accommodation in our society leads me to identify myself as Disabled — not by my Autistic brain, but by society’s lack of understanding.

PDAers, especially children, are often given unhelpful, stigmatizing labels such as noncompliant, stubborn, difficult, oppositional, defiant, manipulative, unmotivated, uncooperative, etc.

Pathological or rational?

Other Autistic experts, such as Damian Milton and Richard Woods, have redefined PDA as Rational Demand Avoidance (RDA).

RDA is described as an understandable and rational response to demands which cause distress, anxiety, discomfort, or are overwhelming to the individual.

In their recent paper, Autistic researcher Allison Moore explains that when Autistic people do exercise agency and engage in self-advocacy, we are at risk of being labelled demand avoidant.

Autistics are less likely to concern ourselves with social norms, and when we engage in independent decision making that resists or challenges these neuronormative expectations, we are more likely to attract the PDA label.

In their own paper, the person who coined the term PDA describes PDAers as Autistics who have an atypical and surface-level “degree of sociability that allowed social manipulation as a major skill”.

One definition of manipulation is to control or play upon by artful, unfair, or insidious means especially to one’s own advantage.

Insidious is something which is subtle yet harmful — so labelling someone with PDA is to assume their social skills are only developed such that the person uses them to get their way at the expense of others.

Take what you need from it

Some Autistics have found the PDA profile tremendously helpful. Some parents of Autistic children have also expressed relief at finding an autism subtype (although it is not a formal diagnosis) that accurately describes their child.

If you’re an allistic (non-Autistic) parent of an Autistic child, I urge you to proceed with caution and critical thinking, please. While it can be incredibly validating to find something that fits your experience, take care not to pathologize reasonable avoidance of demands which cause distress.

As Moore explains, many Autistics experience incredible sensory sensitivities. If a child is resisting attending school, or avoiding an activity or environment that is loud, crowded, or one which has bright lights or strong smells, this sensory input may genuinely cause the child physical or psychological distress.

Trying to avoid demands which cause anxiety, confusion, or are overwhelming is a perfectly reasonable response.

Assumptions vs understanding

If you’re a neurotypical person reading this, try to think of something that causes you to feel similarly.

If you were lactose intolerant, for example, and consuming dairy products caused you extreme physical discomfort, wouldn’t it be reasonable to avoid doing so?

I have Celiac disease (CD) and eating anything which contains gluten causes me serious health issues. If someone were demanding I eat a sandwich made with wholewheat bread, it would be entirely understandable for me to “refuse” — to be uncooperative, noncompliant, or defiant.

Yet knowing that I have CD, it would seem unfair for someone to call me difficult or manipulative, or to pathologize my avoidance of gluten. Yet this is exactly what happens to Autistics on a regular basis, whether under the umbrella or PDA, or one of many other unhelpful and unfair labels.

Behaviourally-based diagnoses such as ADHD, autism, PDA, O.D.D., and others are based on neurotypical assumptions about how one should behave.

Assessments include questionnaires which, for children, are usually filled out by parents or guardians (who are often themselves neurotypical). The answers to the questions are given based on the neurotypical adult’s interpretations of the child’s behaviour.

A neurotypical person may have difficulty understanding the reasons for an Autistic person’s behaviour they perceive as unusual, just as an Autistic would have difficulty understanding a neurotypical’s behaviour they perceive as unusual.

Because allistic people struggle to understand Autistics (mostly because they won’t listen to us, but I digress) does not automatically mean Autistic “behaviours” are pathological.

Different does not equal deficient.
