Abstract Objective This research investigated the internal consistency and test‐retest reliability of the Eating Disorder Examination‐Self‐Report Questionnaire Version (EDE‐Q), a 41‐item measure adapted from the Eating Disorder Examination (EDE). The EDE is a structured clinical interview assessing the key behavioral features and associated psychopathology of eating disorders. Results Results indicated excellent internal consistency and 2‐week test‐retest reliability for the four subscales of the EDE‐Q: Restraint, Weight Concern, Shape Concern, and Eating Concern. There was somewhat less stability in the items measuring the occurrence and frequency of the key behavioral features of eating disorders. Conclusions Overall, results support the psychometric adequacy of the EDE‐Q. © 1999 by John Wiley & Sons, Inc. Int J Eat Disord 25: 349–351, 1999.
