OBJECTIVE: To translate the Galveston Orientation and Amnesia Test into Portuguese and to validate this Portuguese version among Brazilians who had traumatic head injury. METHODS: The Galveston Orientation and Amnesia Test was translated into Portuguese and back-translated to English by independent translators, and equivalence between the two versions of the test was examined. A sample of 73 Brazilians adults with closed head injury was used to establish the psychometric properties of the Portuguese version of the test. RESULTS: The estimate of reliability of the Portuguese version of the test was á = 0.76. The convergent and discriminative validity of the test was determined through comparison between an individual's scores on the Portuguese version of the test and the Glasgow Coma Scale. CONCLUSION: The study's findings suggest that the Portuguese version of the Galveston Orientation and Amnesia Test might be used to measure Post Traumatic Amnesia among Brazilians with closed head injury.
