大量的研究表明了差于死亡健康状态的客观存在,对其效用值的测量可采用的方法包括视觉模拟标尺法、时间权衡法及标准博弈法等,为了获得与好于死亡健康状态效用值对称的值域,还需要采用单调、线性或截尾的方式进行转换。文中系统地介绍了各种测量及转换方法的具体应用和特点,在特定研究中应根据其目的和客观限制选择合适的方法。差于死亡健康状态效用值的研究是健康相关生命质量评价的重要部分,应进行更加深入的探索。
A large number of studies have shown that the objective existence of poor health status of death, the utility of the measure of its available methods include visual analog scale method, time trade-off method and the standard game law, etc., in order to obtain and better than the health status of death symmetry Of the range, but also need to use monotonous, linear or censored way to convert. The paper systematically introduces the specific applications and features of various measurement and conversion methods, and selects the appropriate method according to its purpose and objective limitation in a particular study. Studies that are worse than the utility of death health status are an important part of the health-related quality of life assessment and should be explored further.
