Comparing the effectiveness and predictors of cognitive behavioural therapy-enhanced between patients with various eating disorder diagnoses: a naturalistic study

Abstract Cognitive behaviour therapy-enhanced (CBT-E) is an effective treatment for non-underweight patients with eating disorders. Its efficacy and effectiveness investigated mostly among transdiagnostic samples remains unknown binge disorder. The aim of the present study was to assess several outcome predictors compare CBT-E adult out-patients bulimia nervosa ( n =370), disorder =113), those a restrictive food pattern diagnosed other specified feeding disorders =139). Effectiveness assessed in routine clinical practice specialised centre. Eating pathology measured EDEQ pre- post-treatment, at 20 weeks follow-up. Linear mixed model analyses fixed effect were performed groups. Several completion examined regression analysis. No drop-out found, except diagnosis nervosa. decreased all groups sizes between 1.43 1.70 on EDE-Q total score. There no differences remission rates three end or severity baseline affected response. results can be generalised centres. subgroup differentially benefited from supporting perspective Longer-term follow-up data are necessary measure persistence benefits. Key learning aims (1) What suffering disorder? (2) Does any benefit CBT-E? (3) factors predict response?
