As a part of the new version of Operationalized Psychodynamic Diagnosis (OPD-2), the relationship axis is introduced which was developed on the basis of research and clinical work with the OPD-1. It provides a procedure indicating dysfunctional relationship patterns. The new version is characterized by the following qualities: The relationship axis is based more consequently on the circumplex model of interpersonal behaviour. Therefore, it is suitable for a broader range of evaluation methods linked to this model. It also contains instructions on how to draw a summary of relationship dynamics. Thus the results of the diagnostic assessment can be summarized for clinical and practical purposes and used directly for therapeutic work. In addition, a simplified version of the rating procedure enables identification of the patient's significant problematic relationship themes and his or her personal resources.
