PDA North America

Understanding & Supporting PDA

PDA is an acronym that stands for Pathological Demand Avoidance, or as many prefer, Pervasive Drive for Autonomy. PDA was identified in the UK in the 1980s by Elizabeth Newson and has recently received more attention in the US and Canada since PDA North America was established in March 2020. Many (including us) view it as a profile of autism, with some recent studies linking it to ADHD as well as other neurodevelopmental conditions. We are hopeful for more high quality, peer-reviewed, unbiased research to better understand PDA.

PDA individuals avoid everyday demands using ‘social strategies’ as part of the avoidance, have a strong need for autonomy and control, require unique supports and are socially oriented. These highly stress-prone individuals are often not recognized as autistic, are deeply misunderstood and in need of support.

At PDA North America, we view PDA as a nervous system difference. 

Many families, educators, and therapists are unfamiliar with PDA, and it is often misunderstood or misdiagnosed. Since PDA is not recognized as a distinct diagnosis in the DSM-5 or the ICD-11, many professionals lack awareness or a clear understanding of it. Our organization aims to provide deep insights into PDA and offer practical strategies for supporting and accommodating individuals who experience it.

At PDA North America, we are a non-profit, 501(c)3, that offers a number of resources, trainings and supports to the PDA community & professionals that support them, while focusing on spreading awareness.
