The Chalder Fatigue Scale (CFQ) is a widely used instrument to assess fatigue in both clinical and nonclinical settings. Psychometric properties of the scale and discriminative abilities were examined.
A total of 361 patients with CFS and 1615 individuals in the community were assessed with the CFQ. Principal component analysis (PCA) was used to explore the structure of the scale. Receiver-operating characteristic curve (ROC) was used to investigate the discriminative properties.
Two components, physical and mental fatigue, were identified in the CFS patient group and in the general population samples. Area under the curve for ROC was .91. The fatigue scale effectively discriminates, at high scores, between CFS patients and the general population.
Physical and mental fatigue are clearly separable components of fatigue. The CFQ can discriminate reliably between clinical and nonclinical conditions.
Chalder 疲劳量表（CFQ）是一种广泛用于评估临床和非临床环境下疲劳的工具。本研究旨在评估该量表的心理测量特性和区分能力。
共 361 例慢性疲劳综合征（CFS）患者和 1615 名社区个体接受了 CFQ 评估。主成分分析（PCA）用于探索量表的结构。接受者操作特征曲线（ROC）用于研究区分性能。
在 CFS 患者组和一般人群样本中均确定了两个分量，即身体疲劳和精神疲劳。ROC 的曲线下面积为 0.91。疲劳量表在高分时能有效地将 CFS 患者与一般人群区分开来。
身体疲劳和精神疲劳是疲劳的两个明显可分离的成分。CFQ 可以可靠地区分临床和非临床情况。
