Psychometrics in the treatment of ischemic cerebrovascular diseases

The question on which level of evaluation treatment effects have to be based on, proves the relevance of independent psychological measurements. The Nuremberg Gerontopsychological Inventory NAI is introduced as a symptomatic-oriented approach for the assessment of therapeutically induced changes. It contains four distinct ways of treatment evaluations: (1) the level of assessment of cognitive functioning; (2) subject-rated well-being; (3) observer-rated activities-of-daily-living (e.g. by a nurse), and (4) examiner-rated personality traits. For all test procedures, norm scores as well as detailed test characteristics are computed. Interrelations between the independent data levels proved to be essential for a valid estimation of treatment effects.
