Post-stroke fatigue is a disturbing condition with various physical and psychological facets, which needs to be assessed by meaningful and psychometrically valid and reliable tools. The Chalder Fatigue Questionnaire (CFQ) and Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF) have been designed to assess diverse dimensions of fatigue.
The present study aimed to investigate the psychometric properties of the CFQ and MFSI-SF in people with chronic stroke.
Both measures were translated according to forward-backward standard protocol. This cross-sectional study was conducted with 130 first-time stroke survivors. The multidimensional fatigue inventory, checklist individual strength, fatigue assessment scale, fatigue subscale of profiles of mood state, fatigue severity scale, visual analogue scale-fatigue, beck anxiety inventory, center for epidemiologic studies of depression scale, and 36-item short-form health survey were administered in addition to the CFQ and MFSI-SF. Reliability, precision, known-groups validity, and convergent validity were examined for the CFQ and MFSI-SF.
The results showed an acceptable (Cronbach's alpha = 0.81-0.97) internal consistency and test-retest reliability (intra-class correlation = 0.75-0.97). The CFQ and MFSI-SF revealed good ability ( < 0.001) to differentiate chronic stroke survivors with different disability levels. Significant high correlation ( = -0.61-0.87) was found between CFQ and MFSI-SF and other fatigue scales.
The results of this study showed that the CFQ and MFSI-SF have high reliability and validity for chronic stroke survivors.
中风后疲劳是一种令人困扰的状况，具有各种身体和心理方面，需要通过有意义且心理测量学上有效和可靠的工具进行评估。Chalder 疲劳问卷 (CFQ) 和多维疲劳症状清单-短表 (MFSI-SF) 旨在评估疲劳的不同维度。
本研究旨在调查 CFQ 和 MFSI-SF 在慢性中风患者中的心理测量特性。
根据正向-反向标准协议对这两种方法进行翻译。这项横断面研究共纳入了 130 名首次中风幸存者。除 CFQ 和 MFSI-SF 外，还使用多维疲劳量表、个体力量检查表、疲劳评估量表、情绪状态简表疲劳分量表、疲劳严重程度量表、视觉模拟量表疲劳、贝克焦虑量表、抑郁流行病学研究中心量表和 36 项简明健康调查量表进行评估。对 CFQ 和 MFSI-SF 进行了可靠性、精度、已知组有效性和收敛有效性的检验。
结果显示，CFQ 和 MFSI-SF 的内部一致性和重测信度均为可接受水平（Cronbach's alpha = 0.81-0.97）（组内相关系数 = 0.75-0.97）。CFQ 和 MFSI-SF 能够很好地区分不同残疾程度的慢性中风幸存者（ < 0.001）。CFQ 和 MFSI-SF 与其他疲劳量表之间存在显著的高相关性（ = -0.61-0.87）。
本研究结果表明，CFQ 和 MFSI-SF 对慢性中风幸存者具有较高的信度和效度。
