Poor cognitive flexibility and perfectionism are common features in anorexia nervosa (AN). The current study aimed to investigate cognitive flexibility and clinical perfectionism as potential predictors of AN. Twenty women with a current diagnosis of AN ( age = 28.25, = 7.62) and 170 community participants with no lifetime history of an eating disorder ( age = 29.23, = 9.88) took part in an online cross-sectional study that included self-report questionnaires of cognitive flexibility and clinical perfectionism. It was found that compared to the community sample, women with AN self-reported significantly poorer cognitive flexibility and significantly greater clinical perfectionism. In a regression model, clinical perfectionism (but not self-reported cognitive flexibility) significantly predicted group membership. The specificity and sensitivity of the model were high. These preliminary findings indicate that clinical perfectionism may represent a key feature of AN and may accurately discriminate between participants with and without AN, though more research is required.
认知灵活性差和完美主义是神经性厌食症（AN）的常见特征。本研究旨在调查认知灵活性和临床完美主义作为神经性厌食症的潜在预测因素。20名目前诊断为神经性厌食症的女性（年龄=28.25，标准差=7.62）和170名无饮食失调终生史的社区参与者（年龄=29.23，标准差=9.88）参与了一项在线横断面研究，该研究包括认知灵活性和临床完美主义的自我报告问卷。结果发现，与社区样本相比，神经性厌食症女性自我报告的认知灵活性明显较差，临床完美主义明显更强。在回归模型中，临床完美主义（而非自我报告的认知灵活性）显著预测了组别归属。该模型的特异性和敏感性较高。这些初步研究结果表明，临床完美主义可能是神经性厌食症的一个关键特征，并且可能准确地区分有和没有神经性厌食症的参与者，不过还需要更多的研究。
