Abstract

The Operationalized Psychodynamic Diagnostic of Children and Adolescents (OPD-KJ-2) in Everyday Clinical Practice with the Plämobox: Applicability and Interrater Reliability Abstract: Objective: The OPD-CA2 manual for assessing psychodynamic aspects in children and adolescents is well established in clinical practice. However, publications regarding its reliability and validity are limited to (1) adolescents, (2) the structure of the first version of the manual and not to the comprehensive revision of the OPD-CA2, (3) the axes "structure" and (partly) "conflict" but not the axis "relationship," and (4) missing applicability in everyday clinical practice. Methodology: The present study comprised 42 children aged 6-12 years (age level 2 of the OPD-CA2), with and without mental illness, and assessed them using two randomly assigned raters. We assessed them using a low-structured diagnostic symbol game with miniature figurines and objects based on videotapes. We also tested the interrater reliability of the OPD-CA2 axes. Results: The overall assessment of structure and the assessment of the four subdimensions succeeded with good to very good agreement. We could also determine the presence of relevant conflict dynamics with very high agreement, while not recognizing specific conflicts in the clinical sample. Our assessment of the items of the relationship axis shows a low level of agreement. Conclusions: Overall, we can confirm the reliability of the OPD-CA2 for everyday clinical assessment in the younger age groups. Finally, we discuss which factors contribute to the heterogeneous picture.
