SynopsisPsychometric and clinical correlates of the Eating Attitudes Test (EAT) are described for a large sample of female anorexia nervosa (N = 160) and female comparison (N = 140) subjects. An abbreviated 26-item version of the EAT (EAT-26) is proposed, based on a factor analysis of the original scale (EAT-40). The EAT-26 is highly correlated with the EAT-40 (r = 0·98) and three factors form subscales which are meaningfully related to bulimia, weight, body-image variables and psychological symptoms. Whereas there are no differces between bulimic and restricter anorexia nervosa patients on the total EAT-26 and EAT-40 scores, these groups do indicate significant differences on EAT-26 fractors. Norms for the anorexia nervosa and female comparison subjects are presented for the EAT-26, EAT-40 and the EAT-26 factors. It is concluded that the EAT-26 is a reliable, valid and economical instrument which may be useful as an objective measure of the symptoms of anorexia nervosa.

The development and validation of a new measure, the Eating Disorder Inventory (EDI) is described. The EDI is a 64 item, self‐report, multiscale measure designed for the assessment of psychological and behavioral traits common in anorexia nervosa (AN) and bulimia. The EDI consists of eight sub‐scales measuring: 1) Drive for Thinness, 2) Bulimia, 3) Body Dissatisfaction, 4) Ineffectiveness, 5) Perfectionism, 6) Interpersonal Distrust, 7) Interoceptive Awareness and 8) Maturity Fears. Reliability (internal consistency) is established for all subscales and several indices of validity are presented. First, AN patients (N = 113) are differentiated from female comparison (FC) subjects (N = 577) using a cross‐validation procedure. Secondly, patient self‐report subscale scores agree with clinician ratings of subscale traits. Thirdly, clinically recovered AN patients score similarly to FCs on all subscales. Finally, convergent and discriminate validity are established for subscales. The EDI was also administered to groups of normal weight bulimic women, obese, and normal weight but formerly obese women, as well as a male comparison group. Group differences are reported and the potential utility of the EDI is discussed.

SYNOPSIS Data on the development of a 40-item measure of the symptoms in anorexia nervosa are reported. The scale (EAT) is presented in a 6-point, forced choice, self-report format which is easily administered and scored. The EAT was validated using 2 groups of female anorexia nervosa patients (N = 32 and 33) and female control subjects (N = 34 and 59). Total EAT score was significantly correlated with criterion group membership (r = 0-87, P < 0001), suggesting a high level of concurrent validity. There was very little overlap in the frequency distributions of the 2 groups and only 7 % of the normal controls scored as high as the lowest anorexic patient. Female obese and male subjects also scored significantly lower on the EAT than anorexics. Recovered anorexic patients scored in the normal range on the test, suggesting that the EAT is sensitive to clinical remission.

The cultural pressures on women to be thin and diet have been linked to the expression of serious eating disorders such as anorexia nervosa. The current study attempts to document and quantify the shift toward a thinner ideal shape for females in our culture over the last 20 years. Data from Playboy centerfolds and Miss America Pageant contestants indicated a significant trend toward a thinner standard. Over the same period there was a significant increase in diet articles in six popular women's magazines. These changes occurred within the context of increasing population weight norms for young women. Biosocial implications including the apparent recent increase in anorexia nervosa are discussed.
