The Pittsburgh Fatigability Scale (PFS) is the only validated scale for measuring perceived fatigability in older adults.
We validated the PFS Spanish version by assessing convergent validity with respect to several measures of physical performance, physical activity, physical function and disability.
A cross-sectional validation study of 79 community-dwelling older adults aged 70 and older from Barcelona, Spain was included. Translation-retrotranslation was performed. Convergent validity was assessed in relation to physical activity and performance measurements, and analyzed with Spearman correlation coefficients, a linear trend test and non-linear regression. We also assessed the discriminant validity of the PFS physical score between participants with different physical activity and performance levels.
Higher PFS physical scores were inversely associated with the Short Physical Performance Battery (r = - 0.5, p < 0.001) and weak to moderately correlated with gait speed (r = 0.38, p = 0.001), and self-reported weekly walking time (r = 0.24, p = 0.035).
The PFS is a novel, brief instrument to assess fatigability in Spanish-speaking older adults, with good convergent validity against physical performance measurements. Thus, the PFS can be used in Spanish-speaking populations.
匹兹堡疲劳量表（PFS）是唯一一种经过验证的用于测量老年人感知疲劳的量表。
我们通过评估与多项身体表现、身体活动、身体功能和残疾测量相关的收敛效度，对 PFS 的西班牙语版本进行了验证。
本研究纳入了来自西班牙巴塞罗那的 79 名年龄在 70 岁及以上的社区居住的老年人进行横断面验证研究。进行了翻译-回译。收敛效度评估与身体活动和表现测量相关，并使用 Spearman 相关系数、线性趋势检验和非线性回归进行分析。我们还评估了 PFS 身体评分在不同身体活动和表现水平的参与者之间的判别效度。
较高的 PFS 身体评分与短体适能测试电池（r=-0.5，p<0.001）呈负相关，与步态速度（r=0.38，p=0.001）和自我报告的每周步行时间（r=0.24，p=0.035）呈弱到中度相关。
PFS 是一种新颖的、简短的工具，用于评估西班牙语老年人的疲劳程度，与身体表现测量具有良好的收敛效度。因此，PFS 可以用于西班牙语人群。
