ABSTRACT Currently, the Gothenburg Trismus Questionnaire (GTQ) is the only quality-of-life questionnaire specific for the assessment of trismus. The disease, characterized by limited mouth opening, impairs usual activities such as eating, swallowing, talking, and performing oral hygiene, causing great discomfort to patients. Translation of quality-of-life questionnaires plays an important role in promoting health awareness in the populations of different countries. This study aimed to validate the Portuguese version of the GTQ to allow its effective application in Portuguese-speaking populations. The Portuguese version of the GTQ was successfully validated through the following steps: translation, back translation, cultural adaptation, and revalidation.
