[Validity of axis III "Conflicts" of Operationalized Psychodynamic Diagnostics (OPD-1)--empirical results and conclusions for OPD-2]

Abstract

Objective: Using specific psychometric instruments, we investigate criteria-related validity of axis III ("conflicts") of OPD-1 by a priori formulated hypotheses concerning the relations to the main conflict/mode.

Methods/sample: A consecutive sample of 105 psychotherapy inpatients was examined using self-assessment scales (Inventory of Interpersonal Problems; Rosenberg Self-Esteem Scale, Test of Self-Conscious Affect; Toronto Alexithymia-Scale; Frankfurt Self Concept Scales) and videotaped OPD research interviews in the first week after admission to the hospital. Two OPD-certified raters first rated the interviews independently, then in a consensus rating.

Results: Due to the different frequency of the main conflict and mode, evaluation of 4 of 7 conflicts was possible. The a priori hypotheses could be confirmed for the conflicts Dependence versus Autonomy (both modes), Submission versus Control (active mode), Desire for Care versus Autarchy (active mode), and Self-Value (passive mode).

Discussion: Confirmation of the a priori hypotheses indicates validity of axis III (Conflicts) of OPD. We discuss the small numbers of some conflicts, the comparison of expert rating OPD with self-assessment and the meaning of the results for OPD-2.
