The ‘Extreme Demand Avoidance Questionnaire’ (EDA-Q) is a measure designed to quantify traits of extreme/‘pathological’ demand avoidance in children aged 5-17, on the basis of parent or teacher-report. The questionnaire was developed to ensure that PDA traits were being measured in a consistent way for research purposes.

Other methods to quantify extreme/’pathological’ demand avoidance:
Recent work has identified items from within the Diagnostic Interview for Social and Communication Disorders (DISCO) that are both common in extreme/’pathological’ demand avoidance and specific to it as compared to the rest of the autism spectrum. The publication describing the identification of these DISCO items can be downloaded here.
