| Abstract: | The factor structure of a multidimensional, clinically derived measure of the cognitive and behavioral characteristics of anorexia nervosa and bulimia, the Eating Disorder Inventory (EDI), was investigated in a patient setting. The results showed that eight factors corresponding to the eight original subscales of the EDI were clearly identified in the pattern of factor loadings and that they met conventional standards of internal consistency. The finding of an eight-factor solution using patient responses in this study contrasts with the finding of a clear three-factor solution in an earlier study that employed nonpatient responses. It is suggested that a difference may exist in the meaning of EDI items to patients and nonpatients. However, it is noted that there is a paucity of information in the eating disorders literature that addresses differences between these groups in their attitudes and beliefs regarding eating, weight, body shape, dieting, and self-esteem. This area is clearly one that warrants closer research attention by those working in the eating disorders. |
