Resumo(s): | Objective The Eating Disorder Examination - Questionnaire (EDE-Q) is a widely used self-report measure of eating-disordered behaviors and attitudes. Recent studies utilizing confirmatory factor analyses (CFA) have proposed alternative and shorter forms. The aim of this study was to compare the full-length version of the EDE-Q and several proposed short forms (7-item, 8-item, and 18-item) in terms of their psychometric properties, including concurrent, convergent and discriminant validity, factor structure, and sensitivity to change.Methods Participants from two eating-disorder clinical samples (N = 175 and 38) and from a nonclinical sample (N = 3,413) completed a battery of measures, including the Portuguese version of the EDE-Q. Analyses compared psychometric properties of the available short forms of the EDE-Q among each other.Results All forms of the EDE-Q showed good internal consistency values, correlated highly among each other (r > .90) and with different measures of eating psychopathology (r > .80). All EDE-Q forms were able to distinguish between cases and controls with moderate-to-high accuracy and were sensitive to change. CFA failed to support the proposed factor structure for all the EDE-Q forms, except for the 7-item form.Discussion The present study provides empirical background for choosing between different forms of the EDE-Q. Findings indicate that for nonclinical and for clinical research, including studies of treatment change and outcome, the short forms of the EDE-Q can be used. A shorter version is a viable alternative when less time-consuming alternatives are needed, such to quickly screen for eating-disorder psychopathology or to perform session-by-session treatment monitoring. |
