The scale encompassed orientation to time, place and person and was intended for geriatric patients and patients suffering from psychogeriatric disorders who had been institutionalized for at least 14 days. The reliability according to the Kuder-Richardson formula number KR20 was 0.83 and the test-retest reliability was 0.84. The scale differentiated between patients with senile dementia and/or cerebral arteriosclerosis and patients without such disorders.
