Abstract

This research assessed the stability of the Eating Disorder Inventory (EDI; Gamer, Olmstead, & Polivy [1983]. International Journal of Eating Disorders, 2, 75–34). over a 7-year period in a female, non-clinical population. Of 401 women who initially completed the EDI, 282 (70.3%) completed the EDI again 1 year later. Pearson correlations calculated between the EDI total score and its eight subscale scores indicate considerable stability in the total score and the Drive for Thinness, Body Dissatisfaction, Ineffectiveness, Perfectionism, and Interpersonal Distrust subscales of the EDI. There was less stability in the Bulimia, Interoceptive Awareness, and Maturity Fears subscales. Several explanations of these findings are discussed.
