共有95名新加坡华人参加了面谈。总体来看,大多数受访者能够完全集中精神回答问题,也能够完全理解视觉尺度法和标准博弈法中的问题。大多数受访者认为视觉尺度法(66．3％)和标准博弈法容易或非常容易完成(70．5％),但是这些比例在高教育程度的受访者中均显著(或以接近显著水平)高于低教育程度的受访者。通过视觉尺度法和标准博弈法测得的4个健康状态(即MA、MB、MC、AW)的效用值,高教育程度的受访者要高于低教育程度的受访者,但二者没有统计学意义。总体来说,不同教育程度受访者的健康效用值是合理的,即随着健康状态变差(从MA、MB、MC到AW),效用值呈下降趋势。
A total of 95 Singaporean Chinese took part in the interview. Overall, most of the interviewees can fully concentrate on answering questions and can fully understand the problems in the visual scale method and the standard game method. Most respondents believe that the visual scale method (66.3%) and the standard game method are easy or very easy to complete (70.5%), but these proportions are significant (or nearly so) in highly educated respondents. Level) respondents who are above the low education level. The utility values of the four health statuses (ie, MA, MB, MC, AW) measured by the visual scale method and the standard gambling method are higher for the higher educational level than for the lower educational level, but both Not statistically significant. In general, the health utility value of respondents with different educational levels is reasonable, ie, as the health status deteriorates (from MA, MB, MC to AW), the utility value shows a decreasing trend.
