Psychometric evaluation of the eating disorder examination and eating disorder examination-questionnaire: a systematic review of the literature.

OBJECTIVE The purpose of this study was to systematically review the reliability of scores on the Eating Disorder Examination (EDE) and the Eating Disorder Examination-Questionnaire (EDE-Q) and to examine the validity of their use as measures of eating disorder symptoms. METHOD Articles describing the psychometric properties of the EDE and EDE-Q were identified in a systematic search of major computer databases and a review of reference lists. Articles were selected based on a priori inclusion and exclusion criteria. RESULTS Fifteen studies were identified that examined the psychometrics of the EDE, whereas 10 studies were found that examined the psychometrics of the EDE-Q. DISCUSSION Both instruments demonstrated reliability of scores. There is evidence that scores on the EDE and EDE-Q correlate with scores on measures of similar constructs and support for using the instruments to distinguish between cases and non-cases. Additional research is needed to broaden the generalizability of the findings.
