Anorexia Nervosa
Conditions
Brief summary
The main aim of this project is to determine the short and long-term effectiveness of an out-patient treatment for patients with anorexia nervosa. Specifically, we will measure whether TBT-S in addition to treatment as usual (TAU) will be more effective than TAU alone in reducing eating disorder psychopathology. Assessments will be conducted at four timepoints; pre and post TBT-S, and at 3 and 12 months follow-up. Primary outcome measure is eating disorder psychopathology, with the hypothesis that patients receiving TBT-S in addition to TAU will show significantly greater reduction in eating disorder psychopathology from TBT-S treatment admission to 3 month follow-up, compared to controls.
Detailed description
Participants in the intervention arm will receive five days of TBT-S in addition to treatment as usual. TBT-S is administered to three to six adult anorexia nervosa patients with up to four supports per patient. The treatment structure consists of five consecutive days of treatment, up to 7,5 hours each day. Staff requirements for TBT-S are three clinicians, one dietician and one medical staff. Adults referred to a local psychiatric centre (DPS) for out-patient anorexia nervosa treatment, and their supports, will be eligible to participate in the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Eating Disorder Psychopathology | Baseline, after 1 week and at 3 and 12 months follow-up | Eating Disorders Examination Questionnaire (EDE-Q). Participants report symptomatology on a 7-point Likert scale from 0 (no days) to 6 (everyday). The EDE-Q contains 4 subscales: Restraint, Weight Concern, Eating Concern, and Shape Concern. Subscale scores are calculated by finding the averages of the subscale items. A global score is also calculated by averaging the subscale scores. Scores range from 0 to 6; higher scores indicate higher levels of eating disorder pathology. |
