Assessment of eating disorders in bariatric surgery candidates: Self-report questionnaire versus interview

TLDR

The study aims to compare the Eating Disorder Examination interview with its self‑report counterpart, the EDE‑Q, in bariatric surgery candidates. Ninety‑eight morbidly obese gastric bypass candidates completed both instruments. The EDE and EDE‑Q subscale scores were significantly correlated, but questionnaire scores were higher; agreement was lowest for Eating Concern and Shape Concern, and classification of binge eating showed only modest concordance. © 2000 John Wiley & Sons, Inc.; Int J Eat Disord 28:465–469.

Abstract

Objective To compare the Eating Disorder Examination (EDE), an investigator-based interview for the assessment of the specific psychopathology of eating disorders, with the EDE-Q, a self-report questionnaire based directly on it. Method Ninety-eight morbidly obese gastric bypass surgery candidates were administered both instruments. Results The four subscale scores (Restraint, Eating Concern, Weight Concern, and Shape Concern) generated by the EDE and EDE-Q were significantly correlated, although the questionnaire scores were significantly higher. Eating Concern and Shape Concern exhibited the lowest levels of agreement. Frequency of binges (objective bulimic episodes) as rated by the EDE and EDE-Q was significantly correlated and was not significantly different. However, variability in ratings contributed to only modest agreement with respect to classification of patients as binge eaters. Discussion Overall, there were lower levels of agreement between the EDE and EDE-Q than have been previously found in other samples. © 2000 by John Wiley & Sons, Inc.
