Question:

During

most of its long history, the public function in mental health primarily was on

care of the chronically ill mental patient, as illustrated by the large

hospitals for the mentally ill. This activity in personal health services

contrasted with the usual public health focus on prevention of disease and

protection of the health of the public. Differing perspectives and operating

modes were often reflected in organizational separation of mental health from

public health at the state level. At the federal level, mental health

responsibilities remained within the Public Health Service, although mental

health groups have advocated the maintenance of a separate identity for mental

health programs both at the state and federal levels in order to assure

sufficient attention to these important health problems.
