While much of the development of consultation programs in mental health centers has been independent of the traditional treatment program, this document describes a consultation program which is closely integrated with an agency's treatment program. The emphasis is on system change and the development of prevention programming. The system-crisis model, as it is called, identifies treatment cases as having five perspectives: biological, intro-psychic, individual, family and community. This paper focuses on the community level intervention model and its four systems: community agencies, governing entities, formal groups and informal groups. The goal of mental health consultation is seen as increasing those behaviors in community systems which enhance the mental health of clients and decrease behaviors which are harmful to them. Included are assessment processes, intervention design, and implications and evaluation of the model. While geographically specific, the model could be adapted for other comminities. (Author/BMW)
