Attrition and outcome in self-help treatment for bulimia nervosa and binge eating disorder: A constructive replication
Abstract
The aim of the study was to assess the efficacy of a 12-week CBT-based pure and guided self-help among 29 patients with full and subthreshold bulimia nervosa, and binge eating disorder. In the intention-to-treat analyses, self-help had a moderately positive and sustained effect on the patients' eating problems. The patients reduced their mean number of objective bulimic episodes and purging behavior by 26% and 22% over the course of treatment. The corresponding reduction levels for the treatment completers (n=21) were 41% and 34%, respectively. As in the previous study, there were no significant differences between the pure and guided self-help mode in terms of outcome, and the results were sustained 6 months after the end of the treatment. The findings are discussed in relation to the shorter duration of the self-help, the lower rate of attrition, and the characteristics of the sample compared to the earlier trial.

Non-completion in research studies of online interventions typically ranges from 30-60%.
“non-completion in research studies of online interventions typically ranges from 30-60% [20, 21] and is as low as 1% [21] and 0.5% [22] for interventions offered in open access format.”

Low adherence can moderate intervention outcomes, with longer exposure to an intervention yielding greater benefits.
“Low adherence has clear implications for research and clinical practice, as it can: (i) skew interpretations of efficacy if not clearly measured and reported, and (ii) moderate intervention outcomes, with longer exposure to an intervention yielding greater benefits [20, 23-26].”

“Although several studies (e.g. Carter & Fairburn, 1998) show the guided self-help to be superior to pure self-help (no guidance from a professional), some studies show no significant differences between the two modes of delivery of self-help (e.g. Ghaderi & Scott, 2003).”

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.
