This study focuses on the views of professional health care providers within a geographical district in Sweden. A total of 52 interviews with persons representing different professional levels within psychiatry and the social services were conducted. The purpose was to compare their understanding of what their responsibility entailed as well as their perceptions of goals and required competence. A content analysis, supplemented with interpretations within a hermeneutic tradition, showed that there are both similarities and differences within and between the two organizations. A common finding is that professionals with the least education are to a great extent responsible for the practical care of persons with long-term mental illness. The implication of this finding is that it is important to be aware of this division of responsibility when developing psychiatric nursing and the home care services according to the needs of long-term mentally ill patients.
