[Contributions of psychotherapy research to theory and practice in interconceptional differential indications].

Several changes in the social conditions of psychotherapeutic care in the public health service call for the development of a theory and practice of differential treatment selection for heterogeneous schools of psychotherapy, e.g. psychoanalysis and behaviour therapy. To do this, first some basic problems of interconceptional differential indication have to be solved. Furthermore, findings of the empirical psychotherapy research should be used for working out such a theory. Results of two important fields of psychotherapy research are presented and discussed with respect to their relevance to differential treatment selection. Conclusions are drawn for a theory of interconceptional differential indication and some principles of differential treatment selection pertaining to heterogeneous treatments are formulated.
