The aim of this study was to translate and validate the Functional Assessment of Chronic illnesses Therapy-Fatigue (FACIT-fatigue subscale) in Iran.
The Persian version of the FACIT-fatigue scale was developed using the forward-backward translation method. The questionnaire was then presented to a consecutive sample of breast cancer patients (n = 208) attending the Iranian Center of Breast Cancer (ICBC). The reliability was assessed by internal consistency and test-retest using Cronbach's α and intraclass correlation coefficient (ICC), respectively. Convergent validity was examined by correlation between the FACIT-fatigue scale and the Hospital and Depression Scale (HADS). In addition, discriminant validity was evaluated by the ability of the scale to differentiate between patients who differed in disease stage.
The internal consistency of the questionnaire was excellent (Cronbach's α = 0.92). The ICC for the FACIT-fatigue was 0.84. Strong correlations were observed between FACIT-fatigue and depression (r = -0.69) and anxiety (r = -0.72) scores. The FACIT-fatigue discriminated well between subgroups of patients who differed in stage (p < 0.001) and probable caseness of anxiety and depression disease (p < 0.001).
The Iranian version of the FACIT-fatigue subscale is a valid and reliable instrument to measure fatigue in cancer patients.
本研究旨在将慢性疾病治疗功能评估-疲劳量表（FACIT-fatigue 子量表）翻译成并在伊朗进行验证。
使用正向翻译-反向翻译的方法开发了波斯语版 FACIT-fatigue 量表。然后将问卷呈递给伊朗乳腺癌中心（ICBC）连续就诊的乳腺癌患者（n=208）。采用 Cronbach's α 和组内相关系数（ICC）分别评估内部一致性和重测信度。通过 FACIT-fatigue 量表与医院焦虑和抑郁量表（HADS）之间的相关性来检验其聚合效度。此外，通过量表区分疾病阶段不同的患者的能力来评估其判别效度。
问卷的内部一致性很好（Cronbach's α=0.92）。FACIT-fatigue 的 ICC 为 0.84。FACIT-fatigue 与抑郁（r=-0.69）和焦虑（r=-0.72）得分之间存在很强的相关性。FACIT-fatigue 能够很好地区分疾病阶段不同（p<0.001）和焦虑和抑郁疾病可能发病的患者亚组（p<0.001）。
伊朗版 FACIT-fatigue 子量表是一种有效且可靠的工具，可用于测量癌症患者的疲劳。
