[Adaptation of the Composite International Diagnostic Interview (CIDI) for the assessment of comorbid mental disorders in oncology patients: the CIDI-O]

Abstract

This article describes the development of an oncology-specific adaptation of the Composite Diagnostic International Interview (CIDI) for the assessment of comorbid mental disorders in cancer patients. The specific problems related to the assessment of mental disorders in cancer patients are described, in particular the overlap of somatic and mental symptoms as well as the insufficiently elaborated assessment of adjustment disorders and cancer related posttraumatic stress using structured and standardized procedures. The modification strategies that fostered the development of the CIDI-Oncology (CIDI-O) are described. Primary purpose of this adaptation is to enhance the diagnostic spectrum of the CIDI adding the diagnostic group of stress-related mental disorders.
