Treatment of Anorexia Nervosa in Children and Adolescents: An Integrated Family Based and Metacognitive Approach

Study Overview
=================
Brief Summary
-----------------
The goal of this study is to evaluate the treatment effects of an integrated treatment called Family-based and Metacognitive therapy for patients with Anorexia Nervosa. In addition, we will evaluate if an active follow-up of the patients will reduce the number of relapses, which is common during the 1 year after discharge. Fifty patients aged 12-18 years old and their parents will be invited to participate in this study and all will receive the same treatment but be randomly allocated to different follow-up conditions. The active follow-up includes 3 sessions of Metacognitive therapy and the passive follow-up includes ordinary follow-up, with no booster sessions. The patients will be assessed at baseline, pre-treatment, post-treatment, and at 6 and 12 months follow-up.

Detailed Description
-----------------
The study is an evaluation of a new approach to treating Anorexia Nervosa (F.50.0 and F 50.1) called Family-based and Metacognitive therapy. The treatment integrates both family-based work approach, where the parents learn to be in control of the meal situation and communicate better with their child. The metacognitive treatment approach, is targeting the child to work with its problems with emotional regulation and self-esteem issues, but also their attitudes to body and weight. Our aim is to both address what the overall effect of the treatment will be, but also to test if an active follow-up after discharge will lead to reduced relapse rates in the 12 months after treatment. We will apply the same approach to all included patients (A-B design), but the patients and their parents will be allocated to one of two different conditions for follow-up. The active follow-up involves receiving 3 sessions of metacognitive therapy, whereas the other group gets ordinary follow-up, with no sessions of MCT. All patients are assessed at baseline, pre-treatment, post-treatment, and by 6 and 12 months follow-up. The purpose of the design is to evaluate if the rate of relapse during the first year after discharge can be reduced
