Abstract [en]

Objective: This study aimed to describe the quantity, scope, and fundamental characteristics of recently published randomized controlled trials (RCTs) of psychological interventions.

Methods: We queried two major databases (PsycINFO and PubMeD) for primary reports published in 2010 of RCTs of psychological interventions for participants with a medical condition. We collected data on the characteristics of the trials, participants, interventions, outcomes, and reports.

Results: Of 3,696 retrieved reports 295 primary publications were included. About half (53%) of trials included participants with a mental disorder and more than half evaluated interventions based on a cognitive behavioral therapy (CBT) framework. A majority of trials recruited participants in North America and Europe (79%). A minority of the trials focused on children and adolescents (17%) or the elderly (8%). The median sample size of the intervention arm was n = 41. Thirty-nine percent of trials reported solely patient-reported outcomes. Only 5% of reports indicated funding from for-profit organizations. The median 2010 impact factor of the journals in which reports were published was 2.96.

Conclusion: 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.
