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

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 functi...

Description
Summary: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
