Method: Translation and Cultural Adaptation group International Society for Pharmacoeconomics and Outcomes Research guidelines were followed (preparation, first forward translation, reconciliation, back translation, revision of back translation, harmonization, cognitive debriefing, revision of debriefing results, syntax and orthographic revision, final report). Conclusion: A careful and qualified cross-cultural translation and adaptation of an instrument contribute for measuring what it is designed to measure across cultures. Presenting this process, besides its final product, provides the opportunity that this experience could be replicated for adaptation of other instruments.
