Randomized controlled trials (RCTs) of psychological interventions are still much less frequently published than drug trials. To have four papers (Bower et al. 2003; Proudfoot et al. 2003; Simpson et al. 2003; Gabbay et al. 2003) within a single issue of a leading psychiatry journal is indeed unusual. Together these four major papers provide evidence of the benefits and limitations of psychological interventions for common mental disorders.
