Abstract: To develop a Portuguese short form, the Eating Attitudes Test-40 (EAT-40) was administered to a community sample of 922 female students and to a clinical sample of 63 females suffering from an eating disorder. With the EAT responses of the community sample a factor analysis was performed and items with factor loadings ge 0.30 were selected. Internal consistency was computed for both the instrument and the factors. To study the discriminant capacity the proportion of symptomatic answers and the mean scores were compared between the clinical (N = 63) and control (N = 63) samples. Three factors were extracted: Drive for Thinness (14 items, alpha = .839), Bulimic Behaviours (8 items, alpha = .670), Social Pressure to Eat (3 items, alpha = .758). The short form is composed of 25 items and shows good internal consistency = 0.839. Symptomatic answers for all items (except one) and total mean scores were significantly higher (p < .001) in the clinical sample than in community sample.
