A scale of disability and prognosis in long-term mental illness.

The article discusses the scale of disability and prognosis in long-term mental illness. The study describes an attempt to devise a new prognostic test, using material which was originally collected in order to study the cost of rehabilitation. In this study, about one hundred and eighty-four long-stay mentally ill patients have been studied over the ten years starting 1961 to 1970, during which they were exposed to an active rehabilitation regime. The total net cost to the state of maintaining each individual during the period has been taken as an index of individual performance under the regime and subsequently.
