Abstract

PRAXEDES, Marcus Fernando da Silva et al. Cross-cultural Adaptation of the Oral Anticoagulation Knowledge Test to the Brazilian Portuguese. Ciênc. saúde coletiva [online]. 2017, vol.22, n.5, pp.1615-1629. ISSN 1678-4561.  https://doi.org/10.1590/1413-81232017225.17782015.

Patients’ knowledge about oral anticoagulant therapy may favor the achievement of therapeutic results and the prevention of adverse pharmacotherapy-related events. Brazil lacks validated instruments for assessing the patient’s knowledge about treatment with warfarin. This study aimed to perform the cross-cultural adaptation of the Oral Anticoagulation Knowledge (OAK) Test instrument from English into Portuguese. This is a methodological study developed in an anticoagulation clinic of a public university hospital. The study included initial translation, synthesis of translations, back-translation, review by the experts committee and pre-testing with 30 individuals. We obtained semantic equivalence through the analysis of the referential and general meaning of each item. The conceptual equivalence of the items sought to demonstrate the relevance and acceptability of the instrument. The process of cross-cultural adaptation produced the final version of the OAK Test in Brazilian Portuguese entitled “Teste de Conhecimento sobre Anticoagulação Oral”. There was a suitable semantic and conceptual equivalence between the adapted version and the original version, as well as an excellent acceptability of this instrument.

Keywords : Patient medication knowledge; Questionnaires; Warfarin.
