Development of the 'Extreme Demand Avoidance Questionnaire' (EDA-Q): Preliminary observations on a trait measure for Pathological Demand Avoidance
This paper provides in-depth information about the development of ‘The Extreme Demand Avoidance Questionnaire’ (EDA-Q). It was published in 2013; a time when the awareness of PDA was increasing amongst professionals.
The purpose of this study was to develop and test the validity of the EDA-Q. This was a relatively new questionnaire-measure of extreme demand avoidance. The aim was to quantify the extent to which a child displays PDA features based on parent-reported information.
It was concluded that the EDA-Q was a potentially useful research tool (rather than a diagnostic tool) for identifying the PDA profile. Although aimed at professionals, this paper would be useful to parents who may have experience of the EDA-Q and would like to research its validity and origins.
