There has been limited research comparing the efficacy of different fatigue rating scales for use with individuals with chronic fatigue syndrome (CFS). This investigation explored relationships between two commonly-used fatigue rating scales in CFS research, the Fatigue Scale and the Fatigue Severity Scale. Theoretically, these scales have been described as measuring different aspects of the fatigue construct. The Fatigue Scale was developed as a measure of the severity of specific fatigue-related symptoms, while the Fatigue Severity Scale was designed to assess functional outcomes related to fatigue.
Associations of these scales with the eight definitional symptoms of CFS and with eight domains of functional disability were examined separately in: (1) an overall sample of individuals with a wide range of fatigue severity and symptomatology; (2) a subsample of individuals with CFS-like symptomatology, and, (3) a subsample of healthy controls.
Findings revealed that both scales are appropriate and useful measures of fatigue-related symptomatology and disability within a general population of individuals with varying levels of fatigue. However, the Fatigue Severity Scale appears to represent a more accurate and comprehensive measure of fatigue-related severity, symptomatology, and functional disability for individuals with CFS-like symptomatology.
比较不同疲劳评定量表对慢性疲劳综合征（CFS）患者有效性的研究有限。本研究探讨了CFS研究中两种常用疲劳评定量表——疲劳量表和疲劳严重程度量表之间的关系。从理论上讲，这些量表被描述为测量疲劳结构的不同方面。疲劳量表是作为特定疲劳相关症状严重程度的一种测量工具而开发的，而疲劳严重程度量表旨在评估与疲劳相关的功能结果。
分别在以下人群中检验这些量表与CFS的八项定义性症状以及八个功能残疾领域的关联：（1）具有广泛疲劳严重程度和症状学表现的个体总体样本；（2）具有CFS样症状学表现的个体子样本；（3）健康对照子样本。
研究结果表明，在不同疲劳水平的个体总体人群中，这两种量表都是与疲劳相关症状学和残疾的合适且有用的测量工具。然而，对于具有CFS样症状学表现的个体，疲劳严重程度量表似乎是对疲劳相关严重程度、症状学和功能残疾更准确、更全面的测量工具。
