Zurich-Bern multidimensional meta-analysis of psychotherapy for depression

Projektleitung: Dr. phil. Thomas Munder, Prof. phil. Dr. Birgit Watzke, Dr. phil. Markus Wolf

Psychotherapy for depression is delivered in different modalities: Face-to-face or via the internet, with internet-based interventions divided in those that provide guidance (e.g., via emails from therapists) or not (i.e, self-help). We want to investigate whether or not randomized trials of these modalities differ in clinically relevant features of participants and the control groups used. Further, we are interested in the relation of guidance in internet-based psychotherapy with outcome. More specifically, our objectives are: 1. Investigate and compare clinical features of participants in RCTs investigating different psychotherapy settings 2. Investigate and compare features of control conditions in RCTs investigating different psychotherapy settings 3. Investigate the role of degree of support in internet-based psychotherapy
 
Inclusion criteria for studies are: Population: Adults with depressive symptoms as primary current health problem. Intervention: (a) Face-to-face psychotherapy, or (b) guided internet-based psychotherapy, (c) self-guided internet-based psychotherapy or (d) interventions mixing features of these interventions (e.g., blended therapy). Control: Treatment-as-usual or waiting list. Outcomes: Change in depressive symptoms, treatment dropout. Data to calculate standardized mean differences Settings: Outpatient face-to-face psychotherapy or internet-based psychotherapy Publication date: 2000 or later. All coding will be conducted in duplicate by two independent coders. Disagreements will be discussed and resolved in consensus. (see Munder, T., Krieger, T., Wolf, M., Berger, T., & Watzke, B.
