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 > or = 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.
为编制葡萄牙语简版，对922名女学生的社区样本和63名患有饮食失调症的女性临床样本进行了进食态度测试40项问卷（EAT - 40）调查。利用社区样本的EAT问卷回答进行了因子分析，并选取了因子载荷≥0.30的项目。计算了该量表及各因子的内部一致性。为研究判别能力，比较了临床样本（N = 63）和对照样本（N = 63）中症状性回答的比例和平均得分。提取出三个因子：追求瘦身（14项，α = 0.839）、暴食行为（8项，α = 0.670）、进食的社会压力（3项，α = 0.758）。简版由25个项目组成，内部一致性良好，为0.839。临床样本中所有项目（除一项外）的症状性回答和总平均得分均显著高于社区样本（p < 0.001）。
