Medically unexplained physical symptoms, somatization disorder and abridged somatization: studies with the Diagnostic Interview Schedule.

This paper reviews recent research that used the Diagnostic Interview Schedule (DIS) to characterize medically unexplained symptoms and their clustering in clinical and community populations. While the type of symptom(s) differed little across samples, the distribution of a less restrictive construct of somatization ('abridged' somatization) showed interesting differences across the various groups. The authors propose that in view of its relatively high prevalence, abundant psychiatric comorbidity and the simple and unintrusive nature of the assessment, use of the abridged construct may have practical value particularly when exploring psychopathology among medical and community populations.
