Obsessionality and eating intrusions in patients with eating disorders and the general population

Abstract

Eating disorders (ED) and obsessive-compulsive disorder (OCD) are different clinical entities, although they share psychopathological elements that have been insuffi ciently investigated. Our objectives are fi rstly to analyze, in patients with ED, relationship between OCD symptoms and cognitive intrusions with eating content, their emotional impact, and strategies for controlling them and, secondly, to examine to what extent OCD symptoms predict these intrusions in patients with ED. In the general population, results showed signifi cant associations between OCD symptoms and frequency of intrusions on physical exercise, emotional consequences, dysfunctional appraisals, and control strategies, which persisted after controlling for age, body mass index, depression, and anxiety. In ED patients, associations with OCD symptoms persisted only for emotional consequences and dysfunctional appraisals. These results indicate that the relationship between both disorders is explained by the importance that patients give to the unpleasant cognitive experiences, rather than by the frequency with which these are experienced.
