Efficacy of cognitive–behavioural therapy and other psychological treatments for adult depression: meta-analytic study of publication bias

Open access

Abstract

Background: It is not clear whether the effects of cognitive–behavioural therapy and other psychotherapies have been overestimated because of publication bias. Aims: To examine indicators of publication bias in randomised controlled trials of psychotherapy for adult depression. Method: We examined effect sizes of 117 trials with 175 comparisons between psychotherapy and control conditions. As indicators of publication bias we examined funnel plots, calculated adjusted effect sizes after publication had been taken into account using Duval & Tweedie's procedure, and tested the symmetry of the funnel plots using the Begg & Mazumdar rank correlation test and Egger's test. Results: The mean effect size was 0.67, which was reduced after adjustment for publication bias to 0.42 (51 imputed studies). Both Begg & Mazumbar's test and Egger's test were highly significant (P<0.001). Conclusions: The effects of psychotherapy for adult depression seem to be overestimated considerably because of publication bias.

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.
