What this study supports
Supports the claims that CBT effects were large against control conditions (g = 0.75 to 0.88), smaller after adjustment for publication bias, and small to moderate against care as usual or pill placebo. Only 17.4% of trials were rated high quality, and most anxiety trials used waiting-list controls.
- Who was studied
- 144 randomised trials (184 comparisons) of CBT versus waiting list, care as usual or pill placebo for major depression, generalised anxiety, panic and social anxiety disorder.
- Design
- Meta-analysis
- Level of evidence
- Syntheses of controlled studies: meta-analyses and systematic reviews of experiments and trials.
