Validation of the Spanish version of the Pittsburgh Fatigability Scale for older adults.


ABSTRACT: BACKGROUND:The Pittsburgh Fatigability Scale (PFS) is the only validated scale for measuring perceived fatigability in older adults. AIMS:We validated the PFS Spanish version by assessing convergent validity with respect to several measures of physical performance, physical activity, physical function and disability. METHODS: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. RESULTS:Higher PFS physical scores were inversely associated with the Short Physical Performance Battery (r?=?-?0.5, p?
