Aims: The aim of this study was to develop and validate a short version of the Eating Disorder Examination Questionnaire (EDE-Q) for sessional outcome assessment, which is sensitive to clinical change. Method: A principal component analysis was conducted to determine the factor structure of 489 EDE-Qs completed by individuals with a range of eating disorders. Rasch analysis was carried out on each identified factor. The statistical information and expert ratings (N=10) informed the inclusion/exclusion criteria for each EDE-Q item. The EDE-Q's response scale properties were also investigated using the Rasch model. Data from people with (N=54) and without eating disorders (N=503) were collected through an online survey to assess the reliability, validity and sensitivity of the new measure. Results: A 12-item short version, the Eating Disorder Examination Questionnaire Short (EDE-QS) was developed. Initial psychometric evaluation showed that the EDE-QS is a reliable, valid and sensitive questionnaire. Conclusions: The EDE-QS appears suitable for the use as a brief and user-friendly sessional outcome measure.
