The Eating Disorder Examination-Questionnaire (EDE-Q) is a well-established self-report questionnaire for the comprehensive assessment of eating disorder (ED) psychopathology. It is based on the Eating Disorder Examination (EDE2), a structured clinical interview, considered the method of choice for diagnosis and assessment of EDs. EDE-Q8 is a short form containing 8 items (Kliem et al. 2016).
