The rigid and obsessional features of anorexia nervosa (AN) have led researchers to explore possible underlying neuropsychological difficulties. Numerous studies have demonstrated poorer set-shifting in patients with AN. However, due to a paucity of research on the connection between neuropsychological difficulties and the clinical features of AN, the link remains hypothetical. The main objective of this study was to explore the association between set-shifting and body checking.
The sample consisted of 30 females diagnosed with AN and 45 healthy females. Set-shifting was assessed using the Wisconsin Card Sorting Test (WCST) and frequency of body checking was assessed using the Body Checking Questionnaire (BCQ).
The analysis showed no significant correlations between any of the WCST scores and the BCQ.
The results suggest that there is no association between set-shifting difficulties and frequency of body checking among patients with AN. An alternative explanation could be that the neuropsychological measure included in this study is not sensitive to the set-shifting difficulties observed in clinical settings. We recommend that future studies include more ecologically valid measures of set-shifting in addition to standard neuropsychological tests.
神经性厌食症 (AN) 的刻板和强迫特征促使研究人员探索潜在的神经心理障碍。许多研究表明，AN 患者的转换能力较差。然而，由于对神经心理障碍与 AN 临床特征之间联系的研究较少，这种联系仍然是假设性的。本研究的主要目的是探讨转换能力与身体检查之间的关系。
该样本包括 30 名被诊断为 AN 的女性和 45 名健康女性。使用威斯康星卡片分类测试 (WCST) 评估转换能力，使用身体检查问卷 (BCQ) 评估身体检查的频率。
分析显示，WCST 评分与 BCQ 之间没有显著相关性。
结果表明，AN 患者的转换能力困难与身体检查频率之间没有关联。另一种解释可能是，本研究中包含的神经心理学测量对临床观察到的转换能力困难不敏感。我们建议未来的研究除了标准的神经心理学测试外，还应包括更具生态效度的转换能力测量。
