Changes in obsessive-compulsive symptoms during inpatient treatment of anorexia nervosa.

These results indicate that obsessive-compulsive symptoms decrease during inpatient treatment of AN although they are not primarily targeted during treatment. Furthermore, these improvements seem to be associated with general improvements in AN symptomatology, suggesting the absence of a "symptom shift". Yet, effect sizes were small and obsessive-compulsive symptoms were still clinically elevated in patients with comorbid OCD at discharge, suggesting that these patients need OCD-specific, psychotherapeutic aftercare.
