A Scale of Disability and Prognosis in Long-Term Mental Illness

Abstract

Hoenig (1967) has recently and comprehensively summarized the extensive literature on the prognosis of schizophrenia. In a section on existing prognostic tests he criticizes the vagueness of the items to be scored, the variety of prognostic criteria and the low validity of the resulting scales. The present paper describes an attempt to devise a new prognostic test, using material which was originally collected in order to study the cost of rehabilitation.
