PDA (Pathological Demand Avoidance) is widely understood to be a profile on the autism spectrum, involving the avoidance of everyday demands and the use of ‘social’ strategies as part of this avoidance.
WE UNDERSTAND…
PDA individuals share autistic characteristics and also have many of the ‘key features’ of a PDA profile.
PDA does not appear as a separate diagnostic condition in nationally and internationally recognised diagnostic manuals such as DSM-V or ICD-10.
We prefer the term Pervasive Drive for Autonomy (PDA) rather than Pathological Demand Avoidance, because it reflects respect for neurodivergent experiences rather than framing them as disordered or oppositional. A pervasive drive for autonomy describes a nervous system–level need to maintain choice, control, and self-direction. For people with this profile, everyday demands, even things they want or need to do can trigger a genuine threat response, leading to avoidance, distress, shutdown, or the need to regain a sense of agency. This is not about being difficult, manipulative, or unwilling; it is a protective response rooted in neurology. Understanding PDA through an autonomy-focused, neuroaffirming lens allows us to support safety, trust, and collaboration, rather than compliance.
We do not make this as a separate diagnosis. However, for a child who has been assessed with us as being on the autism spectrum and presents with a PDA profile, this will be recognised and described within the child or adult’s assessment report and diagnosis.
