Psychotherapy services and the prevalence of mental disorders in urban and rural areas.

This study addresses the issue of need for and provision of psychotherapy care in urban and rural areas. In the first part, prevalence of mental disorders based on epidemiological field studies in the county of Traunstein and the city of Mannheim are discussed. Among patients of general practitioners the prevalence of mental disorders was slightly higher in Mannheim than in Traunstein. Concerning the provision of care, results of a questionnaire survey of a random sample of 1542 nonmedical counsellors or psychotherapists in Traunstein, Mannheim and the metropolitan area of West Berlin are presented. The rate of nonmedical therapists/100,000 inhabitants was the same for Traunstein and Mannheim. A more detailed analysis of their service capacity revealed that it was by 17% to 20% higher for Mannheim than for Traunstein; the prevalence of mental disorders in patients of general practitioners was shown to be about 10% higher in Mannheim than in Traunstein. Under the assumption that there is a linear relationship between prevalence and need for care, there appears to be a slight, but not marked undersupply of services by doctors and nonmedical counsellors or psychotherapists in Traunstein as compared to Mannheim. In comparison, the districts of West Berlin were classified into those with high and those with a low percentage of blue collar workers. The rate of nonmedical counsellors or psychotherapists in the "upper class" districts in West Berlin was almost four times higher than that for the "lower class" districts of West Berlin, in Mannheim and Traunstein. The rate/100,000 for the service capacity of nonmedical counsellors or psychotherapists in the "upper class" districts of West Berlin was much higher, and in the "lower class" districts of West Berlin much lower, than in Traunstein or Mannheim. Our data show that there are some discrepancies in the provision of care between rural and urban areas, which however are not large when Traunstein is compared with Mannheim; there were however, substantial discrepancies in the provision of care between cities (Mannheim and West Berlin) and between districts within the same city (West Berlin).
