Recent randomized controlled trials of psychological interventions in healthcare: A review of their quantity, scope, and characteristics

This snapshot of the research on psychological interventions suggests that the evidence base for psychological interventions is expanding mainly for CBT interventions for adults in high-income countries. Although the restrictive inclusion criteria limit the generalizability of these results, researchers and funding agencies might be advised to strive for greater diversity regarding interventions, geographical/cultural settings and age groups. Regularly updated reviews of this research field, with gradually refined methodology and increased scope, may further inform funders and researchers.
