The Reliability of a Survey Psychiatric Assessment Schedule for the Elderly

Abstract

The Survey Psychiatric Assessment Schedule (SPAS) was used in a survey of elderly people living at home and in institutions to examine its reliability in determining mental state. A psychiatrist assessed the same subjects using the Geriatric Mental State Schedule (GMSS) and classified psychiatric disorder into three broad groups: organic disorders, schizophrenia and paranoid disorders, and affective disorders and psychoneuroses. The agreement between the psychiatrist's classification of mental state and the classification derived from SPAS was found to be satisfactory for organic disorders and less satisfactory for functional disorders. The limitations of this method of identifying psychiatric illness are examined.
