There has been substantial debate on the need for decreasing discounting for monetary and health gains in economic evaluations. Next to the discussion on differential discounting, a way to identify the need for such discounting strategies is through eliciting the time preferences for monetary and health outcomes. In this article, the authors investigate the perceived time preference for money and health gains through a pilot survey on Dutch university students using methods on functional forms previously suggested. Formal objectives of the study were to review such existing methods and to pilot them on a convenience sample using a questionnaire designed for this specific purpose. Indeed, a negative relation between the time of delay and the variance of the discounting rate for all models was observed. This study was intended as a pilot for a large-scale population-based investigation using the findings from this pilot on wording of the questionnaire, interpretation, scope and analytic framework.
对于在经济评估中降低货币和健康收益的贴现率,存在大量的争论。除了对差异化贴现的讨论之外,通过引出对货币和健康结果的时间偏好,可以确定是否需要这种贴现策略。在本文中,作者通过对荷兰大学生的一项试点调查,使用先前提出的方法,研究了对金钱和健康收益的感知时间偏好。该研究的正式目标是回顾这些现有方法,并在一个特定目的设计的问卷的便利样本上对其进行试点。实际上,所有模型中,延迟时间和贴现率方差之间都存在负相关关系。本研究旨在为使用该试点调查结果的大规模基于人群的调查提供一个试点,包括问卷的措辞、解释、范围和分析框架。
