Objective The aim of this study was to develop, evaluate, and standardize a short form of the well‐established Eating Disorder Examination‐Questionnaire (EDE‐Q). The newly developed EDE‐Q8 was required to reflect the originally postulated structure of the EDE‐Q . Method Data were drawn from two nationwide representative population surveys in Germany: a survey conducted to develop the EDE‐Q8 in 2009 ( N = 2,520); and a survey conducted in 2013 ( N = 2,508) for the evaluation and calculation of EDE‐Q8 percentiles. Results The EDE‐Q8 had excellent item characteristics, very good reliability and a very good model fit for the postulated second‐order factorial structure. Furthermore, a strong correlation between the EDE‐Q8 and a 13 item short form of the Eating Attitudes Test was observed. Discussion The EDE‐Q8 appears to be particularly suitable in epidemiological research, when an economical assessment of global eating disorder psychopathology is required. © 2015 Wiley Periodicals, Inc.
