Prior work has shown a number of similarities between obsessive-compulsive disorder (OCD) and eating disorders such as perfectionism and depressive symptoms. However, distress and impairment due to eating pathology are also highly comorbid with other disorders, which brings into question whether the relationship with eating pathology is unique to OCD. The aims of the current study were 1) to test perfectionism and depression as mediators of the relationship between OCD and eating pathology, and 2) to determine whether OCD is related to greater distress/impairment regarding eating habits, exercising, or feelings about eating, shape, or weight above and beyond other disorders. Symptoms were assessed in 329 treatment-seeking patients in a secondary analysis of a clinical battery. The results showed that depressive symptoms and perfectionism were found to mediate the relationship between OCD and eating pathology. Additionally, a regression analysis showed that OCD, social anxiety disorder, and panic disorder symptoms were associated with eating pathology to a greater extent than other disorders. These results suggest that distress and impairment related to eating habits, exercising, or feelings about eating, shape, or weight are not unique to OCD and that depression and perfectionism may, in part, explain the association between OCD and eating pathology.
先前的研究表明，强迫症（OCD）与饮食失调之间存在一些相似之处，比如完美主义和抑郁症状。然而，饮食病理导致的痛苦和损害也与其他疾病高度共病，这使得强迫症与饮食病理之间的关系是否独特受到质疑。本研究的目的是：1）检验完美主义和抑郁作为强迫症与饮食病理之间关系的中介变量；2）确定强迫症是否与饮食习惯、锻炼或对饮食、体型或体重的感受方面的更大痛苦/损害有关，且这种关联超出了其他疾病。在对一组临床测试进行二次分析时，对329名寻求治疗的患者的症状进行了评估。结果显示，抑郁症状和完美主义被发现介导了强迫症与饮食病理之间的关系。此外，回归分析表明，与其他疾病相比，强迫症、社交焦虑症和恐慌症症状与饮食病理的关联程度更大。这些结果表明，与饮食习惯、锻炼或对饮食、体型或体重的感受相关的痛苦和损害并非强迫症所独有，抑郁和完美主义可能在一定程度上解释了强迫症与饮食病理之间的关联。
