PARRA-HOLGUIN, Norma N.; FRESAN-ORELLANA, Ana  y  YAMAMOTO-FURUSHO, Jesús K.. Validity and reliability of the Inflammatory Bowel Disease Fatigue Scale in Mexican patients. Gac. Méd. Méx [online]. 2021, vol.157, n.4, pp.364-369.  Epub 13-Dic-2021. ISSN 2696-1288.  https://doi.org/10.24875/gmm.20000637.

Introduction:

Fatigue is an extra-intestinal manifestation of inflammatory bowel disease (IBD).

Objective:

To determine the construct validity, discriminant validity and reliability of an instrument for evaluating the Fatigue Scale for IBD in Mexican patients.

Methods:

Two hundred patients with an IBD confirmed diagnosis were included. Current demographic and clinical characteristics of the condition were evaluated. Each patient answered the IBD Fatigue Scale (IBD-F) and the Pittsburgh Sleep Quality Index (PSQI), which was used to determine IBD-F discriminant validity. A factor analysis of each IBD-F section was performed, independent sample Student's t-tests were used to contrast the PSQI, and reliability was evaluated using Cronbach's alpha.

Results:

The items in both IBD-F sections showed high factor loadings, which explained 68.3 and 38.4 % of variance, respectively. Cronbach's alpha was > 0.80 in both, which discriminated patients with greater sleep disturbances.

Conclusions:

IBD-F is a valid and reliable scale for Mexican patients with IBD. Fatigue objective evaluation will allow timely interventions in order to reduce its impact on patients with IBD.
