Fatigue is a common symptom reported by patients with end-stage renal disease, and it can significantly decrease patients' quality of life. A brief and convenient fatigue assessment tool is needed for Chinese patients on maintenance dialysis.
To determine the psychometric characteristics of the Chinese version of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) in patients receiving maintenance dialysis.
The Chinese version of the FACIT-Fatigue was obtained from the FACIT system. Test-retest reliability of this scale was examined using intraclass correlation coefficients, and the internal consistency was calculated by Cronbach's alpha. Content validity was examined using the content validity index (CVI), scale-level CVI/universal agreement, and scale-level CVI/average agreement. Construct validity was tested using Pearson product-moment correlations of the FACIT-Fatigue scores with the Revised Piper Fatigue Scale, Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index, and disease characteristics during the same period.
A total of 172 patients (111 males and 61 females, mean age 52.6 ± 12.5 years) completed this study, with a median FACIT-Fatigue score of 41 (first and third quartiles 34.3-46). The Chinese version of the FACIT-Fatigue had excellent test-retest reliability (intraclass correlation coefficient = 0.98) and internal consistency (Cronbach's alpha = 0.92); the validity of the scale was supported by CVI, scale-level CVI/universal agreement, and scale-level CVI/average agreement values of at 0.67-1, 0.85, and 0.96, respectively. The standard error of measurement of the FACIT-Fatigue was 1.2. The significant correlations between the FACIT-Fatigue score and the Revised Piper Fatigue Scale (r = -0.658), Hospital Anxiety and Depression Scale (-0.566), and Pittsburgh Sleep Quality Index (-0.489) were supported by the FACIT-Fatigue, with good construct validity (all P < 0.01).
The FACIT-Fatigue had acceptable validity and reliability for maintenance dialysis patients and can be used as a valid tool for the measurement of fatigue among these Chinese patients.
疲劳是终末期肾病患者报告的常见症状，它会显著降低患者的生活质量。对于接受维持性透析的中国患者，需要一种简短便捷的疲劳评估工具。
确定中文版慢性病治疗功能评估-疲劳量表（FACIT-疲劳量表）在接受维持性透析患者中的心理测量学特征。
中文版FACIT-疲劳量表取自FACIT系统。使用组内相关系数检验该量表的重测信度，用克朗巴哈系数计算内部一致性。使用内容效度指数（CVI）、量表水平CVI/全体一致性和量表水平CVI/平均一致性检验内容效度。通过FACIT-疲劳量表得分与修订版派珀疲劳量表、医院焦虑抑郁量表、匹兹堡睡眠质量指数以及同期疾病特征的皮尔逊积差相关分析来检验结构效度。
共有172例患者（男性111例，女性61例，平均年龄52.6±12.5岁）完成本研究，FACIT-疲劳量表得分中位数为41分（第一和第三四分位数为34.3 - 46）。中文版FACIT-疲劳量表具有出色的重测信度（组内相关系数 = 0.98）和内部一致性（克朗巴哈系数 = 0.92）；量表的效度分别得到CVI、量表水平CVI/全体一致性和量表水平CVI/平均一致性值的支持，分别为0.67 - 1、0.85和0.96。FACIT-疲劳量表的测量标准误为1.2。FACIT-疲劳量表得分与修订版派珀疲劳量表（r = -0.658）、医院焦虑抑郁量表（-0.566）和匹兹堡睡眠质量指数（-0.489）之间的显著相关性得到支持，具有良好的结构效度（所有P < 0.01）。
FACIT-疲劳量表在维持性透析患者中具有可接受的效度和信度，可作为测量这些中国患者疲劳程度的有效工具。
