The aim of this study was to evaluate the psychometric properties Brazilian version Oral Anticoagulation Knowledge (OAK) Test. This study, conducted in an anticoagulation clinic, included 201 participants aged over 18 years, who had been using warfarin for more than two months. reliability instrument evaluated by assessing internal consistency (Kuder-Richardson coefficient) and reproducibility (test-retest reliability). validity hypothesizing that there would be a positive correlation moderate strong intensity between correctness levels OAK Test time within therapeutic range (TTR) values, which is measure used quality oral anticoagulation. exhibited good properties. total Kuder-Richardson coefficient value 0.818 intraclass 0.967. revealed values level knowledge, as measured TTR (rs = 0.780). proved reliable valid tool evaluating knowledge patients on therapy with warfarin. may incorporated into practice health care substantiating structuring educational activities ensure improvement about use warfarin, thereby increasing effectiveness safety treatment.
