Validation of the functional assessment of chronic illness therapy-fatigue (FACIT-F) in patients with inflammatory bowel disease.
BACKGROUND Many patients with ulcerative colitis (UC) and Crohn's disease (CD) complain of significant fatigue. To date, no instrument to measure fatigue has been validated in a US inflammatory bowel disease (IBD) population. AIM To determine the reliability and validity of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale in IBD. ⋯ FACIT-F scores were lower in patients with active symptoms (CD 4.6 points, 95% CI 2.4-6.9, P < 0.001; UC 8.5 points, 95% CI 5.5-11.4, P < 0.001). In UC, FACIT-F scores were correlated with ESR (-0.76, 95% CI -0.89 to -0.50), CRP (-0.72, 95% CI -0.88 to -0.43) and HCT (0.53, 95% CI 0.22-0.74). CONCLUSION The FACIT-F scale is a reliable and valid instrument for measuring fatigue in IBD.
