Kognitiv atferdsterapi for spiseforstyrrelser (CBT-E) – en poliklinisk behandlingsstudie

Abstract

Background: Few studies have evaluated the effectiveness of enhanced cognitive behaviour therapy (CBT-E) in clinical settings with a transdiagnostic patient population. The current study aimed to evaluate the effectiveness of CBT-E in a specialised outpatient eating disorder clinic in southeastern Norway. Method: The study involved a transdiagnostic sample of 96 patients (age 30.7 (SD = 9.4), 92.7% women) with longstanding eating disorders and previous failed treatment attempts. We used multilevel modelling to examine change in eating disorder pathology from pre-treatment (T1) to post-treatment (T2) and follow-up 25 weeks later (T3). A total of 57 patients had sufficient data at T2 and 35 patients at T3. Results: We found statistically significant reductions in eating disorder pathology from pre- to post-treatment. Of those who completed treatment, 49.1% met criteria for remission at post-treatment. These changes were stable at follow-up. Implications: CBT-E may lead to reductions in eating disorder pathology and should be considered an acceptable form of treatment for adult patients with eating disorders.
