[First results on the reliability and validity of the OPD-2 axis structure].
OBJECTIVE
In 2006, the manual of the Operationalized Psychodynamic Diagnostics (OPD) was revised and published in its second edition (OPD-2; Arbeitskreis OPD2006). In particular the axis structure was markedly changed. This study assessed the interrater reliability and validity.


METHODS
Two independent raters judged 139 persons with OPD-2 on the axis structure (a third rater judged a partial sample of 20 persons). In addition, patients were investigated with SCID-Interviews for DSM-IV diagnosis and with the following questionnaires: Brief-Symptom-Checklist (BSI), Inventory of Personality Organisation (IPO), and Borderline Personality Inventory (BPI).


RESULTS
Interrater agreement for the axis structure showed sufficient to good results for weighted kappas. The axis structure showed high correlations with the number of DSM-IV diagnoses and the main scales of the BSI, IPO, and BPI.


CONCLUSIONS
The OPD-2 axis structure is a reliable and valid instrument for the assessment of the crucial clinical dimension of "psychic structure".
