27 psychogeriatric patients at Harlem Valley Psychiatric Center were tested by separate examiners on the WAIS Verbal Scale and the Geriatric Interpersonal Evaluation Scale to determine the relationship between these two tests. The sample was restricted to patients who were judged clinically to be "in contact," i.e., oriented as to time, place, and person. The correlation between the WAIS Verbal IQs and the geriatirc scale raw scores was .80; correlations with the individual verbal subscale scores ranged from .58 to .76. Relative advantages and disadvantages of the geriatric scale are discussed.
