How to explain PDA to your family

I'm Sam, I'm neurodivergent, and I run Frog Logic from my lounge. PDA is the one people find hardest to explain, because from the outside it can look exactly like a child, or an adult, who just won't. These are the points that tend to land with grandparents, partners and friends.

Start with this: it isn't won't, it's can't

PDA usually stands for Pathological Demand Avoidance. Many people prefer Persistent Drive for Autonomy. In the UK it's often described as a demand-avoidant profile within autism, not a separate diagnosis.

The key idea for family: an everyday demand can land like a threat, even a kind one, even one the person wants to meet. A child can badly want to go to the party and still be unable to go the moment it becomes expected. The "no" comes from anxiety, not from being spoilt or defiant.

Why the usual advice backfires

  • "Be firmer." More pressure means more threat, and things reliably get worse.
  • "They're fine at school, so it's the parenting." Holding it together all day is often why it falls apart at home, where it's safe.
  • "Just praise them when they do it." Praise can raise the expectation for next time, which makes the next time harder.

What family can actually do

  • Offer choices, not instructions: "Would you like the blue cup or the green one?"
  • Say things indirectly: "I wonder if…" works better than "You need to…"
  • Drop the demands that don't matter, so there's room for the ones that do.
  • Treat a meltdown or a shutdown as distress, not naughtiness.
  • Follow the parent's lead, even when it looks too gentle. They've usually tried firm already.

If they still don't get it

Some relatives take it better from a page than from you, especially if you're tired of explaining. That's what the free guide below is for: two pages, plain English, written to be printed or forwarded before a visit. The PDA Society's website is excellent too if they want more.

Questions people ask

Is PDA a real diagnosis in the UK?

It isn't in the DSM or ICD as a standalone diagnosis. In the UK it's often noted as a demand-avoidant profile within an autism diagnosis. It's still a useful description of a real, recognisable pattern.

Is PDA just bad behaviour?

No. Defiance is a choice. In PDA, everyday demands trigger a threat response, so the avoidance sits largely outside conscious control. Pressure tends to make it worse, not better.

What helps most with PDA?

Reducing demands, offering real choices, indirect wording, giving control over timing, and treating collapse as distress rather than defiance.
