The initial validation of the Quick Cognitive Screening Test

Abstract

The purpose of this study was to validate a sensitive cognitive screening test for detection of a broad range of cognitive deficits, including those not usually identified by existing brief bedside mental status examinations. The Quick Cognitive Screening Test was designed to detect not only global cognitive dysfunction but also specific areas of dysfunction. Areas assessed included orientation, attention and concentration, memory, language, construction, perception, spatial ability, and abstract reasoning. Results showed that the Quick Cognitive Screening Test identified cognitive impairment in all of the neurological and psychiatric patients assessed. Furthermore, the test differentiated between the control group and both the psychiatric group and the neurological group. The reliability and validity of the test were determined. The Quick Cognitive Screening Test shows promise as a brief (less than 30 minutes) reliable and valid screening instrument for detection of cognitive dysfunction in neurological patients.
