[Methods of personality diagnosis in the frame of functional diagnosis]

With its division into the pathodynamic (clinical) and the psychosocial aspect, functional diagnostics corresponds to the dialectic approach to psychic diseases and thus represents the necessary supplementation to the nosological conception which is based on single-line causal relations. An indispensable element of psychosocial diagnostics are personality-psychological test procedures, the applicability and validity of which in postpsychotic patients is discussed. The disturbances of the personality which are to be revealed in this way are unspecific and can be found in all psychiatric disease groups (e.g. neuroses and psychoses). Their knowledge is an important basis for psycho- and sociotherapy which, as compared to most neurotic developments, shows a higher degree of complications due to the multi-step course in postpsychotic disturbances.
