Validation of the brazilian version of the generic six-dimensional short form quality of life questionnaire (SF-6D Brazil)

Abstract

Objective: 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. Methods: 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. Results: 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). Conclusion: The SF- 6D Brazil questionnaire represents a valid option for assessing preferences on economic analysis conducted in Brazil.
