What is PDA?
PDA (Pathological Demand Avoidance), also called Pervasive Drive for Autonomy, is increasingly recognised as a profile on the autism spectrum. The PDA Society and a growing evidence base describe it as an anxiety-driven need to avoid everyday demands — even ones the child actually wants to do.
Key features
- Extreme avoidance of everyday demands (getting dressed, eating, going somewhere fun)
- Use of social strategies to avoid (charm, distraction, negotiation, fantasy, meltdown)
- Surface sociability that can mask deep social difficulties
- Comfort in role play and pretend
- Sudden mood and behaviour changes
- Need to feel in control — not to be controlling, but to feel safe
Why standard autism strategies often don't work
Traditional autism support relies on:
- Visual timetables
- Clear expectations
- Reward charts
- "First… then…" language
- Firm boundaries
For PDA children, these often increase anxiety and avoidance because they feel like demands. Reward charts can become a trigger. Praise can backfire.
What helps instead — low-demand parenting
- Reduce demands to the absolute essentials for safety
- Use declarative language ("I wonder where the shoes are…") instead of direct instructions
- Offer choices ("Do you want to brush teeth before or after pyjamas?")
- Use humour, novelty and play
- Depersonalise demands ("Oh no, the timer says it's time…")
- Allow role play as a way through tasks
- Drop the demand when you can — protect the relationship first
At school
PDA children often have:
- Long histories of school refusal / school can't
- Extreme exhaustion after masking
- Need for highly flexible, relationship-based teaching
- EHCPs that explicitly recognise PDA
EOTAS (Education Otherwise Than At School), flexi-schooling, and home education are common outcomes for PDA families — not failures.
Do
- Lead with relationship
- Pick your battles ruthlessly
- Find a PDA-aware professional
- Connect with the PDA Society (pdasociety.org.uk)
Don't
- Don't use traditional behaviour charts
- Don't punish avoidance
- Don't try to "win" — there is no winning, only connection
PDA is not naughtiness, manipulation or bad parenting. It is anxiety wearing a thousand disguises.
