Cognitive behavioral therapy versus compassion focused therapy for adult patients with eating disorders with and without childhood trauma: A randomized controlled trial in an intensive treatment setting

Objective

Treatments for eating disorders are moderately effective, with cognitive behavior therapy (CBT) providing the strongest evidence. However, it remains important to investigate other interventions, particularly for eating disorders with greater complexity (e.g., substantial comorbidity; trauma history) or for patients who have not responded adequately to previous treatments.

Method

This randomized controlled trial compared CBT against compassion-focused therapy for eating disorders (CFT-E), where half of the sample had a childhood trauma history. The study was pre-registered and adequately powered. A total of 130 patients were randomly assigned to CBT or CFT-E and were assessed at pre-treatment, post-treatment and one-year follow-up. The primary outcome measure was the total score on the Eating Disorder Examination-Interview (EDE), and secondary outcome measures were the Symptom Checklist-90, Inventory of Interpersonal Problems–64 and Post-Traumatic Symptom Scale. Attrition during treatment was low (13%), suggesting good acceptability.

Results

Eating pathology (EDE scores) reduced substantially overall, with large effect sizes, and there were no differences between therapies. However, at follow-up, for patients with a childhood trauma history, CFT-E maintained benefits better than CBT. Conclusion: While both CBT and CFT-E resulted in significant reductions in eating pathology, CFT-E showed superior maintenance of benefits for patients with a history of childhood trauma at one-year follow-up, underlining the necessity of tailored interventions for specific patient subgroups.
