I am often asked, "Does the psychiatric rehabilitation field have a contribution to make in the prevention of severe mental illnesses?" My answer is "Absolutely." Unfortunately, the knowledge and technological base of psychiatric rehabilitation is often not emphasized in the early phases of many mental health initiatives (for example, in deinstitutionalization, managed care, or Medicaid financing). Recent attempts to prevent or preempt the progression of serious mental illnesses seem to evidence a similar omission. Yet there is every reason to believe that the empirically based principles of psychiatric rehabilitation, which have helped people with severe mental illnesses to recover, will also help to preempt illness progression among people at risk of severe mental illnesses. Although the mental health field seems to begin most new initiatives, including the recent focus on the field of prevention, by routinely testing various medications and therapies, sooner or later the value of adding psychiatric rehabilitation knowledge and technology to the therapeutic mix is recognized.
