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.

The effects of alcohol and caffeine on concentration test performance.

Within a 2 x 2 x 2 factorial design using two treatment factors, alcohol vs. placebo and caffeine vs. placebo, with stratification for sex as a non-treatment factor in 2 x 2 x 2 groups of 7 students each, concentration test performance was measured by an arithmetic test. The interesting result was a second-order interaction between the three factors: alcohol as well as caffeine decreased concentration in males; combined treatment performance was interpreted synergistically. For females, alcohol as well as caffeine increased concentration while the combination of both had an antagonistic effect.
