Abstract

INTRODUCTION

Fatigue is a common symptom in patients with inflammatory bowel diseases (IBD). To date, there is no instrument to assess IBD-specific fatigue in German. The aim of this study was to translate the IBD Fatigue (IBD-F) scale and to test its psychometric properties in a German IBD population.

METHODS

After completing the translation process, 20 IBD patients participated in a pilot testing phase. For further analyses, 180 IBD patients with fatigue answered the IBD-F (Sections I, II, III) and the IBD Questionnaire (IBDQ-D). Reliability was tested by using Cronbach's alpha and corrected item-total correlation. Exploratory factor analyses (EFA) were carried out. Spearman's correlation was calculated between the IBD-F and IBDQ-D . 78 patients could be included to calculate the test-retest reliability.

RESULTS

The German version of the IBD-F shows high face and content validity. Internal consistency was excellent, with a Cronbach's alpha of 0.93-0.98. Corrected item-total correlations ranged from 0.51 to 0.89. The correlation between the IBD-F and the IBDQ-D was statistically significant for Section I (rs=-0.59; p<0.01) and Section II (rs=-0.76; p<0.01) of the IBD-F. The EFA identified one relevant factor for each section. Test-retest reliability was acceptable for Section I (intraclass correlation coefficient (ICC)=0.73) and Section II (ICC=0.84).

CONCLUSION

The German version of the IBD-F is a reliable and valid tool to assess fatigue in IBD.

摘要

简介

疲劳是炎症性肠病（IBD）患者的常见症状。迄今为止，尚无用于评估德语 IBD 特异性疲劳的工具。本研究旨在翻译 IBD 疲劳（IBD-F）量表，并在德国 IBD 人群中测试其心理测量特性。

方法

完成翻译过程后，20 名 IBD 患者参加了试点测试阶段。为了进一步分析，180 名患有疲劳的 IBD 患者回答了 IBD-F（第 I、II、III 部分）和 IBD 问卷（IBDQ-D）。使用 Cronbach 的 alpha 和校正的项目总分相关性来测试可靠性。进行了探索性因素分析（EFA）。计算了 IBD-F 与 IBDQ-D 之间的 Spearman 相关系数。78 名患者可用于计算测试-重测信度。

结果

IBD-F 的德文版本具有较高的表面和内容效度。内部一致性极好，Cronbach 的 alpha 为 0.93-0.98。校正的项目总分相关性范围为 0.51 至 0.89。IBD-F 的 I 部分（rs=-0.59；p<0.01）和 II 部分（rs=-0.76；p<0.01）与 IBDQ-D 之间的相关性具有统计学意义。EFA 为每个部分确定了一个相关因素。I 部分（组内相关系数（ICC）=0.73）和 II 部分（ICC=0.84）的测试-重测信度可接受。
