Description
Summary:Psychometric properties of the Eating Disorders Inventory-2 (EDI-2) when used for women with Binge Eating Disorder (BED) are assessed. The EDI-2 was administered to 144 outpatients seeking treatment for BED and 152 outpatients seeking treatment for Bulimia Nervosa (BN). Most EDI-2 scales had acceptable internal consistence for both the BED and BN samples. EDI-2 scales demonstrated adequate stability within a subsample of those with BED who were retested. Confirmatory factor analyses revealed a hypothesized second-order two-factor structure for the original EDI scales for the BED group but not for those with BN. When the provisional EDI-2 scales were included, a two-factor structure was not supported for any group. Some scales differentiated the BED from the BN sample, and the second-order factors correlated with measures of similar constructs. The original EDI scales can be used reliably for those with BED.
