As a part of a Nordic comparative study on sectorized psychiatry, treated incidence was related to the resources and dynamic qualities of psychiatric services in 7 catchment areas. One-year treated incidence cohorts were used. Data was collected concerning number of beds and staff, number of long-term patients and turnover rate of patients in the services and availability of specialized services. A positive correlation was found between rates of outpatient staff and treated incidence. No statistically significant correlation was found between the dynamic qualities of the services and treated incidence. Treated incidence of dependence was the highest in a center that had a special service unit for abusers. Special services for young and old people were not clearly reflected in treated incidence in respective patient groups.
