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.
