The Mini Mental Status Examination, General Health Questionnaire-30, and Beck Depression Inventory were administered to 335 randomly selected hospitalized medical patients. Twenty-eight percent of the population had evidence of cognitive dysfunction on the Mini Mental Status Examination, 61% showed emotional dysfunction on the General Health Questionnaire-30, and 36% were depressed as measured by the Beck Depression Inventory. Only 29% of the patients had no evidence of emotional or cognitive dysfunction. Medical resident diagnostic concordance with these tests was poor. The effects of demographic variables on these test scores were also determined.
