Abstract

Objectives: This study aimed to evaluate the psychometric properties of four candidate cognition bolt-on items and their combinations to the EQ-5D-5L.

Methods: Four cognition items (concentration, memory, calculation, and learning) were developed as separate questionnaire items, and were administered with the standard EQ-5D-5L to 640 individuals in a general population survey in China. From the 4 items, 11 compound items were constructed, and the 'worse level counts' rule was used to calculate a compound item score. Psychometric performance of the cognition bolt-ons was assessed in terms of informativity, convergent validity, explanatory power, and discriminatory power.

Results: The tested four cognition bolt-on items improved the informativity, convergent validity, explanatory power, and discriminatory power of EQ-5D-5L, with calculation and learning yielding better psychometric performance. The compound bolt-on items that coverd a range of cognitive functions demonstrated superior psychometric performance compared to single-aspect bolt-on items, with those items covering calculation and learning resulting in better psychometric performance.

Conclusion: This study confirmed the validity of the tested cognition bolt-ons in a general Chinese population. It supported the use of a compound bolt-on item covering a range of cognitive functions such as the ability to calculate and learn.

在中国普通人群中测试 EQ-5D 的四个认知附加项目。

研究目的本研究旨在评估 EQ-5D-5L 的四个候选认知附加项目及其组合的心理计量特性：方法：在中国的一项普通人群调查中，将四个认知项目（注意力、记忆力、计算力和学习能力）作为独立的问卷项目，并与标准 EQ-5D-5L 一起对 640 人进行问卷调查。从 4 个项目中构建了 11 个复合项目，并使用 "较差水平计数 "规则计算复合项目得分。从信息量、收敛效度、解释力和判别力等方面对认知栓子的心理测量性能进行了评估：结果：测试的四个认知附加项目提高了 EQ-5D-5L 的信息量、收敛效度、解释力和判别力，其中计算和学习的心理测量性能更好。与单一方面的附加项目相比，涵盖一系列认知功能的复合附加项目显示出更优越的心理测量性能，其中涵盖计算和学习的项目具有更好的心理测量性能：本研究证实了在中国普通人群中测试的认知栓塞的有效性。结论：本研究证实了在中国普通人群中测试认知栓塞的有效性，并支持使用涵盖一系列认知功能（如计算和学习能力）的复合栓塞项目。

期刊介绍： The European Journal of Health Economics is a journal of Health Economics and associated disciplines. The growing demand for health economics and the introduction of new guidelines in various European countries were the motivation to generate a highly scientific and at the same time practice oriented journal considering the requirements of various health care systems in Europe. The international scientific board of opinion leaders guarantees high-quality, peer-reviewed publications as well as articles for pragmatic approaches in the field of health economics. We intend to cover all aspects of health economics: • Basics of health economic approaches and methods • Pharmacoeconomics • Health Care Systems • Pricing and Reimbursement Systems • Quality-of-Life-Studies The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfill the above-mentioned requirements. Officially cited as: Eur J Health Econ
