Brief Summary:
The primary objective of this study is to gain knowledge about the effectiveness of enhanced cognitive behavioral therapy (CBT-E) for anorexia nervosa (AN).

Condition or disease Intervention/treatment Phase
Anorexia Nervosa Behavioral: enhanced cognitive behavioral therapy Not Applicable

Detailed Description:

The study will assess the potency of outpatient CBT-E in a sample of patients suffering from AN who are admitted to the Section for Eating Disorders at the Department for Psychosomatic Medicine, Haukeland University Hospital in Bergen, Norway.

Secondary objectives are to (1) prospectively identify baseline predictors of treatment outcome and dropout, (2) determine variables related to the treatment process and patient engagement as predictors of the outcome and/or treatment dropout, and (3) in a multidisciplinary approach, focus on selected pathophysiological mechanisms including changes in the gut microbiota as well as immunological measures in patients with severe AN in different stages of the disease, and determine to what extent they are related to treatment outcome.
