It is postulated that a change in the psychic condition of a patient can be deduced from the determination of the change of the real self-concept alone. The change of self-concepts (real concepts) is to be characterized by an instrument, the Frankfurt Self-Concept Scales, which seeks to grasp self-concept changes using items and scales that are sensitive to change as well as graduated answers with 6 alternatives. In a first empirical investigation, 6 differentiated self-concepts of older people have been repeatedly determined under specific conditions over a period of 6 months using 6 Frankfurt Self-Concept Scales (FSKN). According to the results of the research, changes in self-concepts of older people can be measured with the Frankfurt Self-Concept Scales.
