Objective:
To compare different methods for assessing the features of eating disorders in patients with binge eating disorder (BED).
Research Methods And Procedures:
A total of 47 participants with BED were administered the Eating Disorder Examination (EDE) Interview and completed the EDE-Questionnaire (EDE-Q) at baseline. A total of 37 participants prospectively self-monitored their eating behaviors daily for 4 weeks and then completed another EDE-Q.
Results:
At baseline, the EDE and the EDE-Q were significantly correlated on frequencies of objective bulimic episodes (binge eating), overeating episodes, and on the dietary restraint, eating concern, weight concern, and shape concern subscales. Mean differences in the EDE and EDE-Q frequencies of objective bulimic episodes and overeating were not significant but scores on the four subscales differed significantly, with the EDE-Q yielding higher scores. At the 4-week point, the EDE-Q retrospective 28-day assessment was significantly correlated with the prospective daily self-monitoring records for frequency of objective bulimic episodes and the mean difference between the methods was not significant. The EDE-Q and self-monitoring findings for subjective bulimic episodes and objective overeating differed significantly.
Discussion:
In patients with BED, the three assessment methods showed some areas of acceptable convergence.
