摘要

BackgroundIt is not clear whether the effects of cognitive-behavioural therapy and other psychotherapies have been overestimated because of publication bias.AimsTo examine indicators of publication bias in randomised controlled trials of psychotherapy for adult depression.MethodWe 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 thesymmetry of the funnel plots using the Begg & Mazumdar rank correlation test and Egger's test.ResultsThe 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).ConclusionsThe effects of psychotherapy for adult depression seem to be overestimated considerably because of publication bias.
