The Neuropsychological Impairment Scale-Senior (NIS-S) is a 30-item, orally administered questionnaire for geriatric patients about symptoms of cognitive impairment, affective disturbance, and defensiveness. Clinical and nonclinical norms are described along with validity and reliability information. A procedure is presented for comparing a patient's self-reported cognitive impairment with scores on performance testing, which gauges whether the patient is over- or under-reporting cognitive deficits.
