[Methods for the determination of psycho-social performance within the scope of a model for objectivizing biological...

With the help of experimental findings of a randomized study concerning the dynamics of ageing of a reference population (365 persons of either sex between 18 and 73 years) the authors adopt a principal attitude to methodical questions in objectifying the biological ageing. It is above all demonstrated, if and in how far the psycho-sociometric methods used in a gerontological complex method developed for this purpose meet certain methodical requirements (objectifity, reliability, validity) and are effective from the practical and clinical point of view. On principle it is referred to the necessity of a sex-different interpretation of findings concerning the dynamics of ageing and to the possibilities and borderlines, to attract them for a total assessment of the performance. The clinical model demonstrated for objectifying the biological ageing of man opens a wide field of theoretical and practical possibilities to gain recognitions on dynamics and influencibility of human ageing.
