The main aim of the project is the implementation and evaluation of a stepped care model (SCM) for patients with depression with 6 treatment options of varying intensity and setting, including innovative technologies (e-mental health, telephone-based psychotherapy). Within this complex intervention, patients are treated by a multiprofessional network of health care providers in Hamburg, Germany. The study compares the SCM condition (intervention group) to a control group receiving treatment as usual (cluster randomization on the level of participating general practitioners). It is expected that the SCM condition will show better results regarding reduction of mental symptoms, improvement of quality of life, more efficient access to care and better cost-benefit ratio.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Stepped care intervention (SCM) | Experimental | Patients within the stepped care intervention are screened by general physician using the PHQ-9 (inclusion criterion: >4 points) and diagnosed according to International Classification of Diseases (ICD-10) criteria. Patients receive differentially intensive treatment according to depression severity. Patients with mild depression receive: Step I: Active monitoring or Step II: II.a. Bibliotherapy or II.b. Online self-help ("Deprexis®") or II+: Telephone-based psychotherapy Patients with moderate depression receive: Step III: III.a. Outpatient psychotherapy or III.b. Psychopharmacological treatment Patients with severe depression receive: Step IV: Combined psychotherapy and psychopharmacological treatment, optionally in inpatient setting. |
|
| Control group: treatment as usual | Active Comparator | Patients in the control group are screened by their general physician using the PHQ-D-9 depression scale. Patients included in the study then receive treatment as usual from general physician or other health service providers. |
