  • Title: Can DSM-V facilitate productive research into the somatoform disorders?
    Author: Creed F.
    Journal: J Psychosom Res; 2006 Apr; 60(4):331-4. PubMed ID: 16581353.
    Abstract:
    OBJECTIVE: To highlight key research issues relevant to the diagnostic classification of somatoform disorders and assess whether DSM-V can facilitate research. METHODS: A selective review of recent research findings in relation to the diagnostic categories of somatization disorder and hypochondriasis. RESULTS: The DSM-IV criteria have been ignored by researchers as they were either too restrictive or too broad to study the associated features of somatization and hypochondriasis. In view of the linear relationship between number of bodily symptoms and impairment, the appropriate cutoff point has yet to be established. Ongoing research highlights the perceptual and cognitive aspects of these disorders, which need to be researched further in order to improve management. CONCLUSION: DSM-IV did not facilitate research. Its successor should enable longitudinal studies to further elucidate the causes and perpetuating factors of somatization and illness worry rather than limit such studies by producing artificial criteria that may not be supported by subsequent research.
