FABRICIO-WEHBE, Suzele Cristina Coelho et al. Cross-cultural adaptation and validity of the "Edmonton Frail Scale - EFS" in a Brazilian elderly sample. Rev. Latino-Am. Enfermagem [online]. 2009, vol.17, n.6, pp.1043-1049. ISSN 1518-8345. http://dx.doi.org/10.1590/S0104-11692009000600018.
This study aimed to assess the cross-cultural adaptation of the Edmonton Frail Scale (EFS) and its validity in a Brazilian elderly sample. Translation and back-translation were performed, as well as discussion with professionals and elderly for conceptual equivalence, semantic validation and pre-test of the scale. The scale was applied to 137 elderly aged 65 years or older who lived in the community. In the know-groups validation of the frailty diagnosis between gender, age and cognitive deficit, elder elderly, female and with a cognitive deficit scored higher on the frailty diagnosis. A negative convergent correlation was found between the EFS and the Functional Independence Measure (FIM) (-0.53, p< 0.01) and the total score of the Mini-Mental State Examination (MMSE) (-0.60, p< 0.01). The watch test presented high sensitivity and low specificity levels. The Portuguese version of the EFS was considered valid in the study sample.
