Quality of life and uncertainty in Crohn's disease.

Introduction: Crohn's disease impairs patients' perception of health and has a negative impact on health-related quality of life. Although it is apparent that uncertainty is a significant factor that decreases quality of life, it has never been studied in patients with Crohn's disease. The objective of the present study was to examine the association between level of certainty, self-epistemic authority, Internet information gathering habits, and health-related quality of life.
