Fatigue is a common symptom in patients with inflammatory bowel diseases (IBD). A translated and culturally adapted, instrument with robust psychometric for measuring fatigue in Brazilian patients with IBD is needed.
To translate and cross-culturally adapt the inflammatory Bowel Disease Fatigue Scale (IBD-F) into Brazilian-Portuguese and to test its measurement properties in Brazilian patients with IBD.
Data from 123 patients with IBD were collected. In addition to IBD-F, the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) was used. The measurement properties tested were: internal consistency, reproducibility (reliability and agreement), construct validity, internal and external responsiveness, and ceiling and floor effects.
The Brazilian-Portuguese version of the IBD-F showed excellent internal consistency (Cronbach's alpha of 0.95), excellent reproducibility (ICC=0.97) and a minimal detectable change of 6.0 points. The construct validity was demonstrated with a good correlation between the IBD-F and FACIT-F (r=- 0.46). Effect sizes used for measuring internal responsiveness were moderate among those with Crohn's (0.66) disease and low in patients with ulcerative colitis (0.24). The Brazilian-Portuguese version of the IBD-F presented with high external responsiveness for Crohn's disease (0.84) and with low external responsiveness for ulcerative colitis (0.33). The area under the curve considered for responsiveness was 0.84. Twenty-five percent of floor effects and no ceiling effect were recorded.
The Brazilian-Portuguese version of IBD-F has adequate measurement properties and its use can be recommended in clinical practice and research.
疲劳是炎症性肠病（IBD）患者的常见症状。需要一种经过翻译和文化调适、具有强大心理测量学特性的工具来测量巴西IBD患者的疲劳程度。
将炎症性肠病疲劳量表（IBD-F）翻译成巴西葡萄牙语并进行跨文化调适，同时在巴西IBD患者中测试其测量特性。
收集了123例IBD患者的数据。除IBD-F外，还使用了慢性病治疗功能评估-疲劳量表（FACIT-F）。测试的测量特性包括：内部一致性、可重复性（可靠性和一致性）、结构效度、内部和外部反应性以及天花板效应和地板效应。
巴西葡萄牙语版的IBD-F显示出出色的内部一致性（Cronbach's α为0.95）、出色的可重复性（ICC = 0.97）以及最小可检测变化为6.0分。IBD-F与FACIT-F之间具有良好的相关性（r = -0.46），证明了结构效度。用于测量内部反应性的效应大小在克罗恩病患者中为中等（0.66），在溃疡性结肠炎患者中为低（0.24）。巴西葡萄牙语版的IBD-F对克罗恩病具有较高的外部反应性（0.84），对溃疡性结肠炎具有较低的外部反应性（0.33）。考虑反应性的曲线下面积为0.84。记录到25%的地板效应，未出现天花板效应。
巴西葡萄牙语版的IBD-F具有足够的测量特性，可推荐在临床实践和研究中使用。
