Psychological aspects of Crohn's disease

Abstract

This is a critical review of 16 studies reporting a relationship between Crohn's disease and psychological variables. The studies reviewed indicate a relationship between the psychological variables of stressful life events, personality characteristics, and psychopathology and the onset and/or exacerbation of Crohn's symptoms. Personality characteristics such as depression, anxiety, and dependency are frequently reported as are the occurrence of stressful life events and the presence of psychopathology. The nature of the relationship is not explained by the research to date; however, the findings summarized in this report indicate that additional investigation into this association is warranted. A plan for such research is suggested.
