Following the success of the Operationalized Psychodynamic Diagnosisfor Adults (OPD-2), this multiaxial diagnostic and classificationsystem based on psychodynamic principles has now been adapted forchildren and adolescents by combining psychodynamic, developmental,and clinical psychiatric perspectives.The OPD-CA-2 is based on four axes that are aligned with the new dimensionalapproach in the DSM-5: I = interpersonal relations, II = conflict,III = structure, and IV = prerequisites for treatment. After an initialinterview, the clinician (or researcher) can evaluate the patient's psychodynamicsaccording to these axes to get a comprehensive psychodynamicview of the patient.Easy-to-use checklists and evaluation forms are provided. The set oftools and procedures the OPD-CA-2 manual provides have been widelyused for assessing indications for therapy, treatment planning, andmeasuring change, as well as providing information for parental work.
