[Translation and cross-cultural adaptation of the Edmonton Symptom Assessment System for use in Palliative Care].

The objective of the study was translation and cross-cultural adaptation into Brazilian Portuguese of the instrument Edmonton Symptom Assessment System (ESAS-r). The ESAS-r is a revised version of the instrument ESAS that assesses nine symptoms in Palliative Care. This is a methodological study based on a benchmark composed of six steps: translation, synthesis, backtranslation, expert committee, pre-test and submission of translated version for consideration of the authors. As a result changes were made to the title, statements and certain terms to ensure adequacy of grammar and vocabulary. In the pre-test the term 'nausea' raised doubts, and an additional explanation on this word was suggested. Standardization of instrument columns and the replacement of the term 'depression' for 'sadness' was also recommended. In this study, the ESAS-r instrument was translated and adapted to Brazilian Portuguese, and the next step will be testing the psychometric properties.
