OBJECTIVE
To investigate the psychometric properties of the Brief Fatigue Inventory (BFI) in community-dwelling older adults.
DESIGN
Cross-sectional validation study.
SETTING
Community based.
PARTICIPANTS
Subjects (N=302) were nondemented older adults (mean age, 76.44 y; 54% women).
INTERVENTIONS
Not applicable.
MAIN OUTCOME MEASURES
BFI total, severity, and interference summation scores.
RESULTS
A principal component analysis (PCA) yielded 2 factors, fatigue severity and interference, explaining 65.94% of the variance. Both factors had good reliability, with Cronbach alpha values of .867 for fatigue interference and .818 for fatigue severity. Higher fatigue scores were associated with older age and worse physical and cognitive functions.
CONCLUSIONS
Fatigue is a common and debilitating symptom in the aging population. The current study provides novel findings in validating and establishing a bidimensional factor structure for the BFI in older adults. Severity and interference were differentially related to important health outcomes; therefore, using these subscales in addition to the total BFI score is recommended with older adults. Because of its relatively short administration time and established psychometric properties, the BFI can be successfully incorporated into longitudinal studies and clinical trials.
目的
研究简明疲劳量表（BFI）在社区居住的老年人中的心理测量特性。
设计
横断面验证研究。
地点
基于社区。
参与者
受试者（N=302）为非痴呆老年人（平均年龄 76.44 岁；54%为女性）。
干预措施
不适用。
主要观察指标
BFI 总分、严重程度和干扰综合评分。
结果
主成分分析（PCA）产生了 2 个因素，即疲劳严重程度和干扰，解释了 65.94%的方差。这两个因素都具有良好的可靠性，疲劳干扰的克朗巴赫α值为.867，疲劳严重程度的克朗巴赫α值为.818。更高的疲劳评分与年龄较大以及身体和认知功能较差有关。
结论
疲劳是老年人群中常见且使人虚弱的症状。本研究在验证和建立老年人 BFI 的二维因子结构方面提供了新的发现。严重程度和干扰与重要的健康结果有差异相关；因此，建议在 BFI 总分的基础上，还应使用这些子量表对老年人进行评估。由于其相对较短的管理时间和已建立的心理测量特性，BFI 可以成功地纳入纵向研究和临床试验。
