Show more-based cognitive behavioral therapy for patients with chronic somatic conditions Many patients with chronic somatic conditions regularly experience impairments in physical and psychological functioning in their daily life. A way to support these patients is to offer online programs based on cognitive behavioral therapy (Internet-based cognitive behavioral therapy; ICBT). Although a substantial evidence base already exists regarding the effectiveness of ICBT in treating, for example, depressive symptoms, research on ICBT for chronic somatic conditions is still upcoming. In recent years, a growing number of randomized controlled trials were published that examined the effectiveness of ICBT in various chronic somatic conditions. To systematically and quantitatively evaluate the results of these studies, a metaanalysis was conducted, the results of which are discussed in this article. Results indicated that ICBT is also overall effective for chronic somatic conditions, with small to moderate effect sizes. Larger effects were occasionally found for disease-specific outcomes such as disease symptoms and disease-specific quality of life. A longer treatment duration was found to be marginally related to a larger decrease in depressive symptoms. In addition to the results of the meta-analysis, this article provides an overview of the recent literature regarding several clinically relevant ICBT topics: cost-effectiveness, guided ICBT interventions versus self-help, the role of treatment duration, and optimal design and implementation of eHealth interventions.
