P02-324 - Obsessive symptoms and traits in a sample of Spanish outpatients with anorexia and bulimia nervosa

Results Patients show higher scores than controls in the global punctuation of de MOCQ, and in the checking and doubt subscales. Cases also score higher in harm avoidance (dimension associated with personality disorders of cluster C) and in its subscale anticipatory worry. No differences were found between patients subgroups.

Traits of personality characteristically associated to cluster C and to anxiety disorders seem to be also common features. These results do not support a separated classification of RAN into the OC spectrum.
