Validating the Dutch SF-6D and EQ-5D Using Pairwise Comparisons and Best-Worst Scaling

In April 2011, the LISS panel completed two questionnaires about the valuation of health. The questionnaires serve to validate the Dutch SF-6D and EQ-5D (classifications for describing health) and to understand the valuation of health in the Netherlands.For this purpose, the SF-6D questionnaire uses discrete choice experiments (pairwise comparisons). The EQ-5D is a shorter and simpler instrument than the SF-6D. Therefore, the EQ-5D questionnaire also examines the best way of posing the questions. For this purpose, pairwise comparisons and best-worst scaling are used (the evaluation of three health states simultaneously).
