- Findings We identified 76 RCTs, including 48 trials contributing individual participant data (11 704 participants) and 28 trials with aggregate data (6474 participants). The participants' weighted mean age was 42.0 years and 12 406 (71%) of 17 521 reported were women. There was suggestive evidence that behavioural activation might be beneficial (iMD -1.83 [95% credible interval (CrI) -2.90 to -0.80]) and that relaxation might be harmful (1.20 [95% CrI 0.17 to 2.27]). Baseline severity emerged as the strongest prognostic factor for endpoint depression. Combining human and automated encouragement reduced dropouts from treatment (incremental odds ratio, 0.32 [95% CrI 0.13 to 0.93]). The risk of bias was low for the randomisation process, missing outcome data, or selection of reported results in most of the included studies, uncertain for deviation from intended interventions, and high for measurement of outcomes. There was moderate to high heterogeneity among the studies and their components. 511

Konferensbidrag (refereegranskat)abstract
- Internet-delivered cognitive behaviour therapy (ICBT) has been tested in many research trials but to a lesser extent been directly compared against face-to-face delivered cognitive behaviour therapy (CBT). We conducted a systematic review and meta-analysis on trials in which guided ICBT was directly compared against face-to-face CBT within the same trial. Studies on psychiatric and somatic conditions were included. Systematic searches resulted in 13 studies (total N=1053) that met all review criteria and were included in the review. There were 3 studies on social anxiety disorder, 3 on panic disorder, 2 on depressive symptoms, 2 on body dissatisfaction, 1 on tinnitus, 1 on male sexual dysfunction, and 1 on spider phobia. Face-to-face CBT was either in the individual format (n=6 ) or in the group format (n=7). We also assessed quality and risk of bias. Results showed a pooled effect size at post-treatment across of Hedges g = -0.01 (95% CI, -0.13 to 0.12), indicating that ICBT and face-to-face treatment produce equivalent overall effects. Study quality did not affect outcomes. While the overall results indicate equivalence, there are still few studies for each psychiatric and somatic condition and many for which guided ICBT has not been compared against face-to-face treatment. Thus, more research is needed to establish equivalence of the two treatment formats.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: Although there is sufficient evidence that combined treatments of psychotherapy and pharmacotherapy are more effective for depression in adults than each of the treatments alone, it remains unclear what the exact contribution of active medication is to the overall effects of combined treatments. This paper examines the contribution of active medication to combined psychotherapy and pharmacotherapy treatments. METHOD: Meta-analysis of randomised controlled trials comparing the combination of psychotherapy and pharmacotherapy with the combination of psychotherapy and placebo. RESULTS: Sixteen identified studies involving 852 patients met our inclusion criteria. The standardised mean difference indicating the differences between the combination of psychotherapy and pharmacotherapy and the combination of psychotherapy and placebo was 0.25 (95% CI: 0.03-0.46), which corresponds to a numbers-needed-to-be-treated of 7.14. No significant differences between subgroups of studies were found. CONCLUSION: Active medication has a small but significant contribution to the overall efficacy of combined treatments.

Tidskriftsartikel (refereegranskat)abstract
- No recent meta-analysis has examined the effects of cognitive-behavioural therapy (CBT) for adult depression. We decided to conduct such an updated meta-analysis. Methods: Studies were identified through systematic searches in bibliographical databases (PubMed, PsycINFO, Embase, and the Cochrane library). We included studies examining the effects of CBT, compared with control groups, other psychotherapies, and pharmacotherapy. Results: A total of 115 studies met inclusion criteria. The mean effect size (ES) of 94 comparisons from 75 studies of CBT and control groups was Hedges g = 0.71 (95% CI 0.62 to 0.79), which corresponds with a number needed to treat of 2.6. However, this may be an overestimation of the true ES as we found strong indications for publication bias (ES after adjustment for bias was g = 0.53), and because the ES of higher-quality studies was significantly lower ( g = 0.53) than for lower-quality studies ( g = 0.90). The difference between high- and low-quality studies remained significant after adjustment for other study characteristics in a multivariate meta-regression analysis. We did not find any indication that CBT was more or less effective than other psychotherapies or pharmacotherapy. Combined treatment was significantly more effective than pharmacotherapy alone ( g = 0.49). Conclusions: There is no doubt that CBT is an effective treatment for adult depression, although the effects may have been overestimated until now. CBT is also the most studied psychotherapy for depression, and thus has the greatest weight of evidence. However, other treatments approach its overall efficacy.

Forskningsöversikt (refereegranskat)abstract
- Background The effects of antidepressants for treating depressive disorders have been overestimated because of selective publication of positive trials. Reanalyses that include unpublished trials have yielded reduced effect sizes. This in turn has led to claims that antidepressants have clinically insignificant advantages over placebo and that psychotherapy is therefore a better alternative. To test this, we conducted a meta-analysis of studies comparing psychotherapy with pill placebo. Method Ten 10 studies comparing psychotherapies with pill placebo were identified. In total, 1240 patients were included in these studies. For each study, Hedges g was calculated. Characteristics of the studies were extracted for subgroup and meta-regression analyses. Results The effect of psychotherapy compared to pill placebo at post-test was g=0.25 [95% confidence interval (CI) 0.14-0.36, I (2)=0%, 95% CI 0-58]. This effect size corresponds to a number needed to treat (NNT) of 7.14 (95% CI 5.00-12.82). The psychotherapy conditions scored 2.66 points lower on the Hamilton Depression Rating Scale (HAMD) than the placebo conditions, and 3.20 points lower on the Beck Depression Inventory (BDI). Some indications for publication bias were found (two missing studies). We found no significant differences between subgroups of the studies and in meta-regression analyses we found no significant association between baseline severity and effect size. Conclusions Although there are differences between the role of placebo in psychotherapy and pharmacotherapy research, psychotherapy has an effect size that is comparable to that of antidepressant medications. Whether these effects should be deemed clinically relevant remains open to debate.

Forskningsöversikt (refereegranskat)abstract
- Background. Although guided self-help for depression and anxiety disorders has been examined in many studies, it is not clear whether it is equally effective as face-to-face treatments. Method. We conducted a meta-analysis of randomized controlled trials in which the effects of guided self-help on depression and anxiety were compared directly with face-to-face psychotherapies for depression and anxiety disorders. A systematic search in bibliographical databases (PubMed, PsycINFO, EMBASE, Cochrane) resulted in 21 studies with 810 participants. Results. The overall effect size indicating the difference between guided self-help and face-to-face psychotherapy at post-test was d=-0.02, in favour of guided self-help. At follow-up (up to 1 year) no significant difference was found either. No significant difference was found between the drop-out rates in the two treatments formats. Conclusions. It seems safe to conclude that guided self-help and face-to-face treatments can have comparable effects. It is time to start thinking about implementation in routine care.
