All-or-Nothing Behavior and Catastrophic Thinking Predict Fatigue in Inflammatory Bowel Disease: A Prospective Cohort Study

Abstract

Patients with inflammatory bowel disease (IBD) often report fatigue. However, the reasons for this are poorly understood. In this study of people with IBD, we demonstrate that all-or-nothing behavior (being very active then needing to resting a while) and catastrophic thinking (making very negative assumptions about outcomes) both predict worsening in fatigue over time.
