Objectives: Validated treatments for adults with bulimia nervosa (BN) and related presentations are scarce, and the current most evidenced treatment — cognitive behaviour therapy for eating disorders — is resource intensive and has suboptimal remission rates; there is, therefore, a need to evaluate the effectiveness of other approaches for treating such conditions in routine NHS services. Design: Data from nine patients in an NHS eating disorder service who received compassion-focused therapy (CFT) for BN or bulimic presentations were analysed retrospectively. Methods: Patients routinely completed a validated scale of eating disorder severity (the EDE-Q) at baseline and end of treatment. Results: All five scales of the EDE-Q showed a mean significant reduction (N = 9), indicating a significant reduction in eating disorder symptomatology, and individual analyses showed clinically reliable reduction in seven out of nine patients’ EDE-Q scores. Conclusions: This is the first article to report a case series of patients who benefitted significantly from receiving CFT for their eating disorder. Limitations of this study are considered along with future directions for research into effective treatments for eating disorders.
