The aim of this study was to assess the psychometric properties and transcultural adaptation into Spanish of the Multidimensional Fatigue Inventory in fibromyalgia patients.
The Spanish version of the Multidimensional Fatigue Inventory (MFI-S) was translated and cognitively pretested following cross-cultural adaptation guidelines. Test-retest reliability, convergent validity, and operational qualities were evaluated in a total of 116 fibromyalgia patients. Convergent validity was assessed comparing MFI-S with a visual analogue scale for global fatigue.
The intra-class correlation coefficients varied from moderate to excellent (from 0.64 to 0.91) and the standard errors of the mean ranged from 0.5 to 1.1 points for the five MFI-S domains. The coefficient of repeatability was less than 2 standard deviations and the limits of agreement ranged from 2 to 4 points for the MFI-S domains. A weak to fair significant relationship was found between each MFI-S domain and the visual analogue scale (from 0.21 to 0.32). The mean time required to complete the MFI-S was 3.2±2.0 minutes. None of the patients needed external help to complete the MFI-S, and there were very few missing values.
The MFI-S developed in this study presents a good reliability and reasonable construct validity for Spanish fibromyalgia patients unaffected by cognitive dysfunction and severe depression. This questionnaire is quick, easy to administer and interpret.
本研究旨在评估纤维肌痛患者多维疲劳量表（MFI）的心理测量特性和西班牙文跨文化适应性。
遵循跨文化适应指南，对多维疲劳量表（MFI）的西班牙文版本进行翻译和认知预测试。在总共 116 名纤维肌痛患者中评估了重测信度、聚合效度和操作质量。MFI-S 与整体疲劳视觉模拟量表进行比较，评估聚合效度。
MFI-S 的五个领域的组内相关系数从中度到优秀（从 0.64 到 0.91），平均标准误差范围从 0.5 到 1.1 点。可重复性系数小于 2 个标准差，MFI-S 各领域的一致性界限范围从 2 到 4 点。MFI-S 各领域与视觉模拟量表之间存在弱到中度显著关系（从 0.21 到 0.32）。完成 MFI-S 的平均时间为 3.2±2.0 分钟。没有患者需要外部帮助来完成 MFI-S，并且很少有缺失值。
本研究中开发的 MFI-S 对不受认知功能障碍和严重抑郁影响的西班牙纤维肌痛患者具有良好的可靠性和合理的结构效度。该问卷快速、易于管理和解释。
