A model developed by Transitional Services for New York, Inc., for collaboration between State and County government under private, not-for-profit auspices is described which attempts to assist the transition of former psychiatric patients into the community. The agency functions are described in terms of: (1) a tri-level housing network including a halfway house, supervised apartments, and independent apartments; (2) a program philosophy based on linkages to the community, especially ties to recreational, medical, dental, psychiatric, vocational, educational, religious, and transportation resources; and (3) the provision of the necessary supports to enable its clients to become productively re-integrated into the mainstream of society.
