In recent years, there has been growing interest in pathologically healthful eating, often called orthorexia nervosa (ON). Much of the literature in this area has been about point prevalence of ON in particular populations, which range from less than 1% to nearly 90% depending on the study. Despite this interest, there has been no extensive examination of whether those with pathologically healthful eating are detected by screening instruments that identify disordered eating. This study examines whether individuals who self-report suffering from ON score in the clinical range on the 26-item Eating Attitudes Test (EAT-26).
Individuals (n = 354) sampled from both clinical and non-clinical settings were administered the EAT-26 to determine whether those who self-identify as having ON scored in a range that suggests disordered eating.
Participants who self-report suffering from ON had a mean EAT-26 score of 30.89 (SD 12.60) scoring in a range that urges individuals to seek additional advice on whether there is an eating disorder present (scores of 20 and higher fall in a range suggesting a possible eating disorder). Furthermore, those in the ON group scored no differently than those reporting other eating disorders, but significantly higher than a non-clinical control group.
Our findings indicate that a screening instrument for a possible eating disorder is sensitive to pathologically healthful eating (but has no specificity).

近年来，人们对病理上健康的饮食（通常称为“健康饮食强迫症”，ON）的兴趣日益浓厚。该领域的许多文献都围绕特定人群中ON的点患病率展开，根据研究不同，患病率从不到1%到近90%不等。尽管有这种兴趣，但对于识别饮食失调的筛查工具能否检测出患有病理上健康饮食的人，尚未进行广泛研究。本研究旨在探讨自我报告患有ON的个体在26项饮食态度测试（EAT - 26）中是否处于临床范围内。
从临床和非临床环境中抽取个体（n = 354），对其进行EAT - 26测试，以确定自我认定患有ON的个体得分是否处于表明饮食失调的范围内。
自我报告患有ON的参与者EAT - 26平均得分为30.89（标准差12.60），该得分范围促使个体就是否存在饮食失调寻求更多建议（得分20及以上表明可能存在饮食失调）。此外，ON组的得分与报告其他饮食失调的组没有差异，但显著高于非临床对照组。
我们的研究结果表明，一种针对可能存在的饮食失调的筛查工具对病理上健康的饮食敏感（但无特异性）。
