Abstract

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

  • The number of binge-eating episodes post-intervention in the current study (M = 5, SD = 7) was comparable to treatment-as-usual in-person CBT-E for patients with BED (M = 5.5, SD = 5).

    “In addition, the number of binge-eating episodes post-intervention in the current study ( M = 5, SD = 7) was comparable to treatmentas-usual (in-person CBT-E) for patients with BED ( M = 5.5, SD = 5) (Melisse et al., 2022).”

    From Effectiveness of web-based guided self-help cognitive behavioral therapy-enhanced for binge-eating disorder: An implementation study (2024) · cites this paper as Melisse et al., 2022

    The Intervention and Patient flow sections describe individually delivered outpatient CBT-E and identify a BED group, so the paper is a relevant in-person treatment comparison. However, the available Table 2 text and Remission Intention-to-treat analysis do not give a post-treatment binge-eating mean of 5.5 or SD of 5. Those figures, and therefore the numerical comparison, cannot be verified from our copy. (LLM, conf=0.78)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
