Clinical Utility of a Rapid Diagnostic Test Series for Elderly Psychiatric Outpatients

Psychiatric evaluation of the elderly is especially difficult for several reasons, e.g., the presence of organic impairment, the effects of multiple drug therapy, and the tendency to confuse the normal concomitants of aging with neurotic symptoms. The authors have developed and evaluated a brief series of self‐report assessment tests (GRDB) designed to assist the psychiatrist in the process of diagnosis. Coefficients of the internal consistency of the seven scales are presented. A comparison was made between 28 psychiatric patients attending a geriatric clinic and 48 well‐functioning elderly persons matched for age and sex, and living in the same community. Results showed that the geriatric outpatients functioned at a lower level of adaptation than did the control group, on all seven scales—depression, daily living skills, social interaction, cognitive skills, number of illnesses, number of life problems, and the use of drugs and alcohol. These findings provide a measure of discriminant validity. The advantages of this brief assessment instrument are discussed. 1978 The American Geriatrics Society
