Psychological factors and stress in inflammatory bowel disease.

The role of psychological distress and personality as predisposing factors for the development of inflammatory bowel disease (IBD) remains controversial. Attempts to investigate the role of psychological factors in IBD exhibited rather conflicting results. Among the studies concerning the effects of stress or depression on the course of IBD, the majority suggest that stress worsened IBD, the rest giving either negative or inconclusive results. However, application of strategies, including avoidance of coping and training patients in problem solving or emotion-oriented, could influence the course of IBD. Large controlled clinical trials are needed in order to clarify the impact of psychological interventions on the quality of life and the course of disease.
