Development of a new assessment strategy in psychosomatic medicine: the diagnostic criteria for psychosomatic research.

The Diagnostic Criteria for Psychosomatic Research (DCPR) are a diagnostic and conceptual framework that was proposed a decade ago by an international group of investigators. The DCPR's rationale was to translate psychosocial variables that derived from psychosomatic research into operational tools whereby individual patients could be identified. A set of 12 syndromes was developed: health anxiety, thanatophobia, disease phobia, illness denial, persistent somatization, conversion symptoms, functional somatic symptoms secondary to a psychiatric disorder, anniversary reaction, demoralization, irritable mood, type A behavior, and alexithymia. These criteria were meant to be used in a multiaxial approach. The aim of this work is to survey the research evidence which has accumulated on the DCPR, to provide specification for their development and validation and to examine the specific DCPR clusters. Their implications for classification purposes (DSM-V) are also discussed.
