摘　　要：目的:比较用不同测量方法得到的效用值之间的差异。方法:采用不同测量方法同时对350例老年性黄斑变性的患者进行效用测量,把用不同测量方法得到的效用值的中位数作为相对标准效用值与各种效用值进行比较、方差分析、相关分析和曲线拟合。结果:用不同测量方法得到的效用值之间的差异和相关性大多具有显著意义,相对标准效用值与各种效用值的曲线方程也具有显著意义,但拟合度都不高。结论:对于相同的对象用不同测量方法得到的效用值是不同的,在没有绝对标准的情况下,本研究得到的结果可以作为用单一方法测量得到的效用值的修正参考。Objective： To compare utility values measured by different instruments. Methods： Different instruments were used to measure utility values in 350 patients who were diagnosed as age-related macuiar degeneration at the same time. The median of utility values measured by different instruments was regarded as relative standard utility value to process comparison, analysis of variance, correlation analysis and curve estimation. Results： Most differences and correlations among utility values measured by different instruments were significant, as well as equations estimated from relative standard utility value and utility values measured by different instruments, but the degree of fitting was not high. Conclusion： The utility values of the same subject measured by different instruments are quite different. The results of the study could provide correction reference to the utility value measured by single instrument in the absence of absolute standard.
