Use of the Diagnostic Criteria for Psychosomatic Research (DCPR) in a community sample.

The authors assessed the prevalence of Diagnostic Criteria for Psychosomatic Research (DCPR) clusters in a community sample and the association between these syndromes and psychosocial variables. A group of 347 consecutive subjects from the general population were administered the semistructured interview for DCPR and a self-rating scale (the Psychosocial Index). A DCPR syndrome was identified in 59% of subjects. These subjects showed more stress and distress and less well-being than those without a DCPR syndrome. Some DCPR syndromes (alexithymia, Type A behavior, irritable mood) are frequently encountered in a community sample and are associated with impairment in quality of life. Other syndromes (demoralization, persistent somatization) that have been frequently found in medically ill persons were uncommon in this general-population sample.
