A Rating Scale of the Mental State: For Use in the Chronic Population of the Psychiatric Hospital

Abstract

The assessment of change in psychiatric patients is never easy. The problem is accentuated in the chronic inhabitants of psychiatric hospitals, since the period of treatment and observation may have to be prolonged, and the changes found may be small and gradual. A rating scale can be of value, in recording findings in a uniform manner and in preserving the observations from selective amnesia, so making comparison possible over a long period. In the present communication we report a scale devised by two of us (F.J.J.L. and A.D.H.) for use with chronic patients. This scale summarizes the relevant parts of the examination of mental state found in standard text books of psychiatry, and we have tried to avoid presuppositions about the meaning or distribution of symptoms.
