Promises and risks of web-based interventions in the treatment of depression .

Abstract

Major depression (MD) is a highly prevalent and severe disorder with many patients having no access to efficient treatments such as pharmaco- and psychotherapy. Web-based interventions promise to be a method to provide resource-efficient and widespread access to psychotherapeutic support. Meta-analyses summarizing studies that use face-to-face psychotherapy as a comparator provide evidence for equivalent antidepressant efficacy. Web-based interventions seem to be particularly efficacious when they are accompanied by some form of professional guidance. However, they are also associated with a variety of possible risks (eg, suicidal crises can be overlooked) and unwanted effects (eg, increase in rumination and somatization due to self-monitoring) that are so far under-studied. Although some naturalistic studies yield smaller effect sizes than randomized controlled trials (RCTs), well-designed interventions with adequate guidance have been shown to be successfully integrable into routine care.
