Psychometric Properties of the Eating Disorder Belief Questionnaire

Objective: The purpose of this investigation was to examine the psychometric properties of the eating disorder belief questionnaire (EDBQ). Method: The EDBQ was administered to clinical patients with bulimia nervosa (n = 44) and nonclinical female university students (n = 298). Six types of psychometric testing were conducted: internal consistency, test-retest reliability, convergent validity, ability to discriminate between clinical and nonclinical groups, exploratory factor analysis, and confirmatory factor analysis. Results: Psychometric testing generally supported the utility of the EDBQ with good internal consistency, 4- to 6-week test-retest reliability, convergent validity, and ability to discriminate between groups. The a priori structure of the EDBQ was shown to provide a good fit to the observed data. Discussion: The results suggest that the EDBQ is a reliable and valid measure that may assist researchers and clinicians aiming to assess eating disorder cognitions in populations with bulimic symptoms.
