In relation to prevalence studies, bulimia and anorexia nervosa symptoms have been reported to be surprisingly high, although such studies have relied upon questionnaire data. The present study examines the reliability and validity of an eating disorder questionnaire (Eating Attitudes Test) in discriminating anorexics and bulimics from a general female college population. Of an initial test sample of 162 subjects, 56 were subsequently interviewed and retested. The results indicated that the questionnaire gave a high false positive rate for both eating disorders. Discussion focuses on limitations of questionnaire data in determining bulimia prevalence rates.
关于患病率研究，尽管此类研究依赖问卷调查数据，但据报告，神经性贪食症和神经性厌食症症状的出现率高得出奇。本研究检验了一份饮食失调问卷（饮食态度测试）在从普通女大学生群体中区分出厌食症患者和贪食症患者方面的信度和效度。在最初的162名测试样本中，随后有56人接受了访谈和重新测试。结果表明，该问卷对这两种饮食失调症都给出了很高的假阳性率。讨论集中在问卷调查数据在确定贪食症患病率方面的局限性。
