Test-retest reliability of the eating disorder examination-questionnaire (EDE-Q) in a college sample

OBJECTIVE The purpose of this investigation was to determine the test-retest reliability of the Eating Disorder Examination (EDE). METHOD This study examined the test-retest and interrater reliability of the EDE in 20 adult women with a range of eating disorder symptoms. Trained assessors administered the EDE to participants on two separate occasions, ranging from 2 to 7 days apart. RESULTS Test-retest correlations were.7 or greater for all subscales and measures of eating disorder behaviors except for subjective bulimic episodes and subjective bulimic days. Interrater reliability was uniformly high with correlations above.9. DISCUSSION Results provide further support for the reliability of the EDE, but suggest that smaller binge episodes may not be reliable indicators of eating pathology.
