The Eating Disorder Inventory-91 (EDI-91) was developed by Garner et al. as a tool for the assessment of the multidetermined psychosocial, cognitive, and behavioral characteristics associated with eating disorders. In order to standardize the Japanese versicn of the EDI-91, 514 healthy females (age 12-36) in the Tokyo metropolitan area were assessed by a newly translated 91-item EDI and the Eating Attitude Test (EAT). Factor analysis was conducted in order to ascertain whether the 11 original subscales described by Garner et al. were applicable to a Japanese group of normal subjects. Correlational analysis was performed between scores on each factor and the EAT. The results showed that 6 factors (34. 48% of variance ; Cronbach alpha = O. 74-0. 89) consisting of 68 items were retained. Different patterns of factor loadings from the original were found. Factor 1 consisted of 13 items from mainly, "Drive for Thinness" and "Bulimia" ; factor 2, "Body Dissatisfaction" ; factor 3, "Impulse Regulation", "Interoceptive Awareness", "Social Insecurity", and "Ineffectiveness" ; factor 4, mainly, "Maturity Fears" ; factor 5, "Social Insecurity" and "Interpersonal Distrust" ; factor 6, "Asceticism", "Perfectionism", "Ineffectiveness", and "Interoceptive Awareness". The finding showed that there was a significant correlation between scores on each factor and the EAT.
