A general population sample of 104 Australian respondents completed an interviewer-administered contingent valuation (CV) survey that asked them to value five scenarios representing the same core improvement in health status. These scenarios varied only in the degree of narrative used to describe the condition causing the health problem being valued and labeling of this health problem. Results indicate no significant difference in willingness to pay (WTP) between expressing symptoms as a brief or moderate narrative, but a significantly lower WTP value when expressed in an extensive narrative. WTP also differed significantly according to condition 'labels'. Possible implications for CV research are outlined.
104名澳大利亚受访者组成的普通人群样本完成了一项由访员实施的条件价值评估(CV)调查,该调查要求他们对代表健康状况相同核心改善的五种情景进行估值。这些情景仅在用于描述导致所评估健康问题的状况的叙述程度以及对该健康问题的标注方面有所不同。结果表明,将症状表述为简短或适度叙述时,支付意愿(WTP)没有显著差异,但以详尽叙述表述时,WTP值显著较低。WTP也因状况“标注”而有显著差异。文中概述了对CV研究可能产生的影响。
