Few countries can provide adequate health services for all the mentally ill, yet none have developed a rational system to decide who should be treated. This innovative book considers ways to resolve this dilemma. The questions are clear: What should the criteria be for deployment of scarce treatment resources? How do we determine and apply such criteria? What are the ethical implications? In this pioneering work, an international team of eminent psychiatrists, epidemiologists, health administrators, economists and health planners examine these questions. This volume is divided into four parts: Part I. Unmet Need: Defining the Problem; Part II. Unmet Need: General Problems and Solutions; Part III. Unmet Need in People with Specific Disorders; and Part IV. Unmet Need: Specific Issues.
