About PDA

Demand Avoidance is a developmental disorder and spectrum condition. It has some similarities with autism and Asperger's Syndrome but also significant differences. At the extreme end of its unique spectrum is Pathological Demand Avoidance (PDA).

PDA is a pervasive developmental disorder (meaning it affects all areas of development) and was first identified by Elizabeth Newson in 2003, although it is still not currently recognised in many tools used for diagnosing autism and other spectrum conditions. It is a complex, challenging and misunderstood condition that is often ignored or not even recognised by many professionals. It is worth noting that strategies which are helpful for people with autistic spectrum disorders may not be useful in cases of PDA.


This quiz should not be considered a diagnostic test. For diagnosis, a thorough assessment by an experienced professional is required.


This quiz is based on the EDA-Q, developed as a part of published research into PDA by O’Nions, E., Christie, P., Gould, J., Viding, E. & Happé, F. in a paper titled Development of the ’Extreme Demand Avoidance Questionnaire’ (EDA-Q): Preliminary observations on a trait measure for Pathological Demand Avoidance published in the Journal of Child Psychology and Psychiatry in 2013.
