THE ROLE OF PSYCHOLOGICAL-FACTORS IN GASTROINTESTINAL CONDITIONS - A REVIEW PERTINENT TO DSM-IV

The authors reviewed the literature to assess the relationship between psychological factors and gastrointestinal conditions. The conditions that were found to be more relevant and worthy of future investigation were nonulcerative dyspepsia, inflammatory bowel disease (regional enteritis), and irritable bowel syndrome. The pertinent findings suggest that an important link exists between psychological factors and gastroenterological disorders, which supports the need for modification of the DSM-III-R's diagnostic category, "Psychological Factors Affecting Physical Condition." In concert with a subcommittee addressing other organ systems and psychological factors, the authors conclude that a diagnostic approach with greater utility would be useful for both researchers and clinicians. A conceptual framework as proposed in DSM-IV could also advance knowledge of psychological factors and their contribution or role in the etiology, perpetuation, and exacerbation of certain gastrointestinal conditions.
