Abstract

The Late Fuction Life and Disability Instrument (LLFDI) was developed to be an assessment tool sensitive to significant changes in the components function and disability in daily activities of elderly community residents. Objectives: Adapting to Portuguese-Brazil and assess the intra-rater and inter the Brazilian version of LLFDI. Methods: To adapt the original U.S. version of LLFDI were involved five translators who performed two translations, a synthesis of the two translations, two back translations thereof, and a subsequent review and evaluation of semantic and cultural equivalence by a multidisciplinary committee. The intra-evaluator final Portuguese version of LLFDI was assessed by comparing the two assessments repeated by the same examiner in one week interval. Interrater reliability was tested by comparing the different raters, held on the same day. We evaluated 45 volunteers (70.13 ± 6.88), living in the community. Results: The reliability scores for limiting total and overall function were considered high reliability for both tests intra-rater (ICC = 0.91 and ICC = 0.97) and interrater (CCC CCC = 0.87 and = 0.92), respectively. Conclusion: The results demonstrate that the translation and adaptation of LLFDI- Brazil is reliable.
