ObjectiveThe aim of this paper was to present the results of the first stage of cross-cultural adaptation of the Functional Activities Questionnaire (FAQ).MethodsThe tool was subjected to translation and re-translation, and the test-retest reliability of a proposed version for use in Brazil was analyzed.ResultsOf the 548 questionnaire respondents, a convenience sample of 68 informants was selected for retesting. Internal consistency was measured by Cronbach's alpha (0.95) while test-retest reliability was assessed using intra-class correlation (0.97). The findings have shown that FAQ is brief - averaging seven minutes to apply, easily understood and has good intra-rater test-retest reliability.ConclusionOur results suggest this adapted version of the FAQ is a reliable and stable tool which may be useful for assessing function in Brazilian elderly. Notwithstanding, the version should be subjected to further analysis with the aim of reaching functional equivalence.
