ABSTRACT
Objective: The study aims to assess interrater reliability of the revised Operationalized Psychodynamic Diagnosis 3 (OPD-3) system. Three OPD axes were included in the reliability analysis: the Levels of Structural Integration Axis (OPD-LSIA), the Conflict Axis (OPD-CA), and the Interpersonal Relations Axis (OPD-IRA). Methods: A heterogeneous sample of n = 80 patients was diagnostically assessed with SCID-I and SCID-II as well as with an OPD interview. Two raters of a group of five independently rated each patient's OPD interview according to OPD-3. Results: Interrater reliability was good to excellent for OPD-LSIA [ICC1,1 = .874 - .920], and moderate to good forOPD-CA [ICC1,1 = .547 - .764] as well as forOPD-IRA at the aggregated level of Agency and Communion [ICC1,1 = .575 - .793], except for raters' self-perceived tendencies to act towards the patient. Conclusion: The revised OPD-3 can be used as a reliable instrument for a psychodynamic diagnosis of conflicts, levels of structural integration, and dysfunctional relationship patterns.
