title: Psychometrics in aging and dementia: advances in geropsychological assessments.
abstract: Description, explanation and prediction of changes occurring in old age, which are based on intervention, are outlined as a basic goal in gerontological research. Appropriate psychological assessment techniques are necessary to reach this goal. The Nuremberg Gerontopsychological Inventory (NAI) is introduced as a set of psychological measurements which enable reliable, valid and sensitive evaluation of intervention-induced changes in old age. Four independent assessment levels, i.e. standardized performance tests, observer-ratings, self-ratings and a personality rating are the core components of this inventory. All assessment techniques are adapted for elderly subjects. Standard scores are available for the age range 55-90 years. Interrelations between the applied independent assessment levels are reported and taken to link different aspects of intervention-induced changes. Measuring psychological performance thus gains practical significance, e.g. in terms of activities-of-daily-living. From 14 independent studies the drug sensitivity of the applied measurements is shown. Finally, some recommendations for future psychometrical research are given.
