This study seeks to present the translation and validation of the SF-6D in the Brazilian context, based on the model and the version developed in the United Kingdom in 2002.


An observational and transversal study. The tools for assessing quality of life were applied, namely HAQ, SF-36, EQ-5D and SF-6D (2002 version). Descriptive statistics and correlation coefficients were used for data analysis.


200 patients with rheumatoid arthritis, with a mean age of 49.22 years, 11.16 years of disease and mean HAQ 1.02 were studied. Preferences measured by the SF-6D, the EQ-5D and the techniques of EVA, TTO and SG were found to correlate among themselves, with Pearson coefficients from 0.19 to 0.66 (p <0.01).


The SF-6D Brazil questionnaire represents a valid option for assessing preferences on economic analysis conducted in Brazil.
