The Eating Disorder Examination (EDE) and Questionnaire (EDE-Q)
The Eating Disorder Examination (EDE)  is a diagnostic interview, which has been modified to reflect current DSM-5 diagnoses. The EDE-Q is the questionnaire form of the EDE, and both are considered the ‘gold standard’ measures of ED psychopathology [329, 330]. As an interview, the EDE is designed to be administered by a clinician, and the developers recommend clinician training to ensure all concepts being assessed are well-understood . However, the EDE-Q is a self-report measure, which can be completed individually, or with the help of a clinician (explaining concepts such as binge eating).
Both measures assess past month cognitive subscales related to ED: restraint, eating concern, shape concern, and weight concern, as well as behavioural symptoms related to these concerns (e.g., frequency of binge eating, vomiting, use of laxatives or diuretics, and overexercise) . The EDE-Q has been validated for use in samples with AOD use disorders . Both instruments are available for free download from http://www.credo-oxford.com/7.2.html.
