No - PDA is not a standalone clinical diagnosis in the UK and does not appear in the ICD-11 or DSM-5, but it is widely recognised as a profile within autism, and some clinicians record 'autism with a PDA profile'.
What PDA is
PDA stands for Pathological Demand Avoidance. It describes a pattern of extreme, anxiety-driven resistance to everyday demands and expectations, from getting dressed to a simple request to sit down. The two diagnostic manuals UK clinicians work from, the ICD-11 and the DSM-5, do not list PDA, so no service in the UK can give your child a standalone diagnosis of PDA. The PDA Society describes PDA as best understood as a profile of autism: the demand avoidance sits alongside the more familiar autistic traits rather than being a separate condition.
How it gets recorded in practice
Because there is no separate PDA diagnosis, recognition happens inside the autism assessment, not in a test of its own. Some NHS and private clinicians will note a 'PDA profile' within an autism diagnosis, often written as 'autism with a PDA profile' or 'demand-avoidant presentation'. Others use the word sparingly or not at all, and a few will tell you flatly that they do not recognise the term. Whether a clinician records it is, in effect, a postcode lottery that varies by area and by individual assessor. The field is still contested: PDA Society practice guidance recommends 'ASD with a PDA profile' as a formulation, while some researchers argue there is not yet enough evidence to treat PDA as a distinct syndrome.
Why this matters for you
The practical point is that PDA is not gatekept behind a PDA diagnosis, because none exists. You cannot ask for a 'PDA test', and you do not need to wait for one. The route in is an autism assessment. National guidance already points this way: NICE guideline CG128 lists demand-avoidant behaviour among the signs to consider when assessing a child for autism, and asks assessors to record a profile of the child's strengths and needs. So if extreme demand avoidance is what you see at home, ask for an autism assessment and ask, in writing, that a PDA profile be considered and documented as part of it.
