Psychometric Properties of the Dutch Version of the Eating Disorder Inventory–3

The psychometric properties of the Dutch version of the Eating Disorder Inventory–3 (EDI-3) were tested in eating disordered patients ( N = 514) using confirmatory factor analyses, variance decomposition, reliabilities, and receiver operating characteristic (ROC) curve analyses. Factorial validity results supported the 12 subscales, but model fit was impaired by correlated item errors, misallocated items, and redundant subscales. At the composite level, the Bulimia subscale was identified as a largely specific source of information that did not contribute much to its overarching composite. Rel... Mehr ...

The psychometric properties of the Dutch version of the Eating Disorder Inventory–3 (EDI-3) were tested in eating disordered patients ( N = 514) using confirmatory factor analyses, variance decomposition, reliabilities, and receiver operating characteristic (ROC) curve analyses. Factorial validity results supported the 12 subscales, but model fit was impaired by correlated item errors, misallocated items, and redundant subscales. At the composite level, the Bulimia subscale was identified as a largely specific source of information that did not contribute much to its overarching composite. Reliabilities for subscales and composites ranged from .6 to .9. ROC curve analysis indicated good to excellent discriminative ability of the EDI-3 identifying clinical subjects against a reference group. In conclusion, further revisions of the EDI-3 might target the item allocation and (over-)differentiation of subscales and composites to further clarify its structure. For the clinical practice, we advise the careful use of the EDI-3, although it might serve as a good screening tool.
