Resum
This paper presents a new scoring algorithm for the SF-6D, one of the most popular preference-based health status measures. Previous algorithms suffer from a phenomenon called the �floor. effect (i.e., lack of sensitivity of the instrument for detecting health gains of individuals whose baseline health is poor). Our algorithm expands the range of utility scores in such a way that the �floor. effect vanishes. We get such a wider range thanks to the use of a lottery equivalent method through which preferences from a representative sample of Spanish general population are elicited.
