Fatigue is an extra-intestinal manifestation of inflammatory bowel disease (IBD).
To determine the construct validity, discriminant validity and reliability of an instrument for evaluating the Fatigue Scale for IBD in Mexican patients.
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.
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.
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.
疲劳是炎症性肠病（IBD）的一种肠外表现。
确定用于评估墨西哥患者 IBD 疲劳量表的工具的结构有效性、判别有效性和可靠性。
纳入了 200 名确诊为 IBD 的患者。评估了患者的当前人口统计学和临床特征。每位患者都回答了 IBD 疲劳量表（IBD-F）和匹兹堡睡眠质量指数（PSQI），用于确定 IBD-F 的判别有效性。对每个 IBD-F 部分进行因子分析，使用独立样本学生 t 检验对比 PSQI，使用 Cronbach's alpha 评估可靠性。
IBD-F 两个部分的项目均显示出较高的因子负荷，分别解释了 68.3%和 38.4%的方差。两个部分的 Cronbach's alpha 均大于 0.80，可区分睡眠障碍较大的患者。
IBD-F 是一种针对患有 IBD 的墨西哥患者有效的、可靠的量表。对疲劳进行客观评估将有助于及时进行干预，以减轻其对 IBD 患者的影响。
