Delivery formats of cognitive behavior therapy in adults with eating disorders: a network meta-analysis
Bibliographic record
Abstract
Although CBT has been found to be effective in the treatment of eating disorders, it is not clear if there are differences between treatment formats. We conducted a network meta-analysis (NMA) of randomized trials of broadly defined CBT comparing individual, group, guided self-help (GSH) and unguided self-help (USH) with each other or with a control condition. The NMA used a frequentist graph-theoretical approach and included 36 trials (53 comparisons; 3,136 participants). Only one trial was aimed at anorexia nervosa. All formats resulted in large, significant effects when compared to waitlists, with no significant difference between formats (group: g = 1.08, 95% CI: 0.84; 1.31; GSH: g = 0.94, 95% CI: 0.75; 1.13; individual: g = 1.06, 95% CI: 0.77; 1.36; USH: g = 0.62, 95% CI: 0.30; 0.93). No significant difference was found between any format and care-as-usual. Analyses limited to binge eating disorder supported the effects of individual, group and GSH formats, with no significant differences between them. Few trials with low risk of bias were available. CBT for eating disorders can probably be delivered effectively in any format, without significant differences between the formats. These results should be considered with caution because of the non-significant differences when compared to care-as-usual and the considerable risk of bias.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
