[Psychometric procedures and questionnaires in geronto-psychological research]

This paper presents the Nuremberg-Geriatric Inventory (NAI), a test and questionnaire battery for geronto-psychological and pharmacological problems. This inventory consists of three modified subtests of the Wechsler-Adult-Intelligence-Scale (WAIS), a maze-pathway, a modified Trail Making test (ZVT), a psychological rating scale, a rating scale for activities-of-daily-living, a self-rating and a questionnaire, containing problems of growing old. The objectivity, reliability and validity of all tests and scales are described, as well as some norms for different groups of patients. First experiences and results using this inventory in longitudinal studies and pharmacological investigations are reported.
