Self-Report and Observer Ratings of Personality Functioning: A Study of the OPD System

Recent considerations around DSM-5 criteria of personality disorders (PDs) demand new concepts of assessing levels of personality functioning. Of special interest are multiperspective approaches accounting for clinicians' as well as patients' points of view. The study investigates observer-rated and self-assessed levels of personality functioning measured by the level of structural integration as defined by the Operationalized Psychodynamic Diagnosis System (OPD). Both perspectives were positively related. The combination of both measures was most efficient in discriminating among 3 diagnostic groups of varying degrees of personality dysfunction. Future studies should take into account expert ratings as well as self-report data.
