Patient-doctor relationship Objective: The study examines whether the treatment of depression with treatments from the guideline according to a collaborative care (CC) model [1,2]is effective compared to care as usual (CAU) in terms of a reduction of depressive symptoms. Principal elements in the CC model are: A. Contracting of the treatment plan by the General Practitioners (GPs) with the patient B. Adherence improving strategies for GPs and casemanager C. Problem Solving Treatment (PST) [3] D. An antidepressant algorithm for the GP setting [4] Design: - Two-armed cluster randomised trial in 40 GP practices (figure 1) [5]. - Stratification for comorbid medical illness - Three regions: Amsterdam, Hoorn and West Friesland. - In cooperation with the department of General Practice, VU University Medical Center, Amsterdam (EMGO). - 2 x 120 patients References: 1.
