Current DSM-IV somatoform diagnoses may inadequately capture many somatizing patients in primary care. By using data from two studies (1,000 and 258 patients, respectively), the authors determined 1) the optimal threshold on a checklist of 15 physical symptoms to screen for a recently proposed somatoform diagnosis, multisomatoform disorder (MSD), and 2) the concordance between MSD and somatization disorder. The optimal threshold for pursuing a diagnosis of MSD was seven or more physical symptoms. The majority (88%) of the patients who met criteria for MSD had either full or abridged somatization disorder. MSD was intermediate between abridged and full somatization disorder in terms of its association with functional impairment, psychiatric comorbidity, family dysfunction, and health care utilization and charges.
