One of the central tasks of psychodynamic diagnosis, next to determini
ng intrapsychic conflicts, central relational patterns, and subjective
forms of experiencing is assessing the psychic structure or the struc
tural disorder. This article develops the structure term from object r
elationship theoretical, ego-psychological, and self-psychological con
cepts of psychoanalysis. This ''Structure of the self in the relations
hip to others'' thus obtained is described with six structural criteri
a (self-perception, self-control, defence, object perception, communic
ation, attachment). In order to be able to dinstinguish the extent and
the quality of structural disorders four structure levels of integrat
ion based on psychoanalytic experience in the out-patient and the in-p
atient setting are differentiated. A basis for an operationalization i
s then made; it is made in the system OPD (Operationalized Psychodynam
ic Diagnostics). First studies regarding practicalibility and reliabil
ity are promising.
