This study investigated whether symptoms of orthorexia nervosa, a conjectured disorder characterized by obsessive thoughts and compulsive behaviors regarding healthy eating, are associated with cognitive inflexibility. Participants (25 in the orthorexia symptoms group, 25 in the control group) completed the Eating Habits Questionnaire and computerized versions of the Wisconsin Card Sorting Test and the Trail Making Test. Of the 11 variable measurements from these cognitive tests, only one significantly differed between the groups, with the orthorexia symptoms group making more errors than the control group on the first part of the Trail Making Test that does not actually require any set shifting. These results suggest that although orthorexia is associated with inflexible thoughts and behaviors specific to healthy eating, the condition does not seem to be associated with cognitive inflexibility as an executive function deficit.
本研究旨在探讨饮食强迫症（一种被认为是由强迫性的健康饮食观念和行为引起的障碍）的症状是否与认知灵活性有关。参与者（25 名饮食强迫症症状组，25 名对照组）完成了饮食习惯问卷和威斯康星卡片分类测试以及连线测试的计算机版本。在这些认知测试的 11 个变量测量中，只有一个在两组之间存在显著差异，饮食强迫症症状组在不需要任何转换的连线测试的第一部分中犯的错误比对照组多。这些结果表明，尽管饮食强迫症与特定于健康饮食的僵化思维和行为有关，但这种情况似乎与认知灵活性无关，即执行功能缺陷。
