Both the scope and effects of deinstitutionalization have been dramatic. This volume examines both positive and negative effects of this mass movement of persons with severe mental illness out of the state hospitals and into the community. The chapters address the following issues: the use of community alternatives to state hospitalization; the very large numbers of persons with severe mental illness who have found their way into the criminal justice system, why this has happened, and what to do about it; the community treatment of mentally ill offenders; how to prevent inappropriate entry of mentally ill persons into the criminal justice system; the value of mental health consultation in courtroom settings; the therapeutic use of mental health conservatorship; and finally, psychiatric rehabilitation. Although deinstitutionalization for the most part can result in a much richer life experience in the community, much more needs to be done to make that occur. This is the 90th issue of the Jossey-Bass series New Directions for Mental Health Services.
