[Fall-related efficacy is associated with the progression of frailty in community-dwelling older people].

A clear association between frailty and fall-related efficacy was thus observed, as indicated in the cross-sectional and longitudinal data analysis. Furthermore, based on the results of the longitudinal data analysis, the short FES-I was found to be able to predict the progression of frailty and it can thus be a useful screening tool for assessing frailty.
