问题：在评价健康状况的人群调查中发现无反应和不可用反应。如果在估值方面没有答复是有选择性的，则不允许将结果值推广到整个调查人群。这可能会限制经验效用值在卫生保健资源分配中的使用。方法：从荷兰普通人群中抽取1400人作为样本，对邮寄的EuroQolc问卷的反应行为进行了四种方法的分析。1.给坚定的非受访者打电话；2.比较受访者和非受访者的邮政编码特征(因为非受访者没有关于背景特征的个人数据)；3.随时间变化的反应分析(波动分析)；4：比较成功(缺失两个以下估值)和不成功的受访者的背景变量，并分析这些背景变量对估值的影响。结果：没有发现选择性无回应的迹象，尽管这种现象似乎很难调查。成功的回答来自于一个稍微年轻、受过更好教育的亚样本。然而，年龄和教育水平对估值的总体影响并不能被显示出来。这一发现与文献相符。结论：虽然不能排除选择性无反应的存在，但其相关性可以认为很小。这一发现对于在配置决策中使用经验效用值是令人鼓舞的。
PROBLEM: Non-response and non-usable response were found in population surveys on valuation of health states. If non-response is selective regarding valuations, then generalization of the resulting values to the whole survey population is not permitted. This could limit the use of empirical utility values in resource allocation in health care.METHODS: Response behaviour of a sample of 1400 from the Dutch general population to the mailed EuroQolc-questionnaire was analyzed by four methods. I. Phoning resolute non-respondents; II. comparison of zip code characteristics of respondents and non-respondents (because individual data on background characteristics were not available for the non-respondents); III. analysis of response over time (wave-analysis); IV: comparison of background variables of successful (less than two valuations missing) and unsuccessful respondents, combined with analysis of the effect of these background variables on valuations.RESULTS: No indications for selective non-response were found, although the phenomenon appeared hard to investigate. The successful response came from a slightly younger and better educated subsample. However, a general influence of age and educational level on valuations could not be shown. This finding is consistent with the literature.CONCLUSION: Although the existence of selective non-response cannot be excluded, its relevance can be considered to be small. This finding is encouraging for the use of empirical utility values in allocative decisions.
