Abstract
:

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.
