LOWERING THE ‘FLOOR’ OF THE SF‐6D SCORING ALGORITHM USING A LOTTERY EQUIVALENT METHOD
提出了一种新的SF-6D评分算法，通过彩票等价法从西班牙普通人群样本中获取偏好，显著降低了效用评分的最低值，扩大了评分范围。
This paper presents a new scoring algorithm for the SF-6D, one of the most popular preference-based health status measures. Previous SF-6D value sets have a minimum (a floor), which is substantially higher than the lowest value generated by the EQ-5D model. Our algorithm expands the range of SF-6D utility scores in such a way that the floor is significantly lowered. We obtain the wider range because of the use of a lottery equivalent method through which preferences from a representative sample of Spanish general population are elicited.
