Preference-based measures allow patients to report their level of health, and the responses are then scored using preference weights from a representative general population sample for use in cost utility analysis. The development process of new preference-based measures should ensure that valid items are selected to reflect the constructs of interest included in the measure and that are suitable for use in preference-elicitation exercises. Existing criteria on patient-reported outcome measures (PROMs) development were reviewed, and additional considerations were taken into account in order to generate criteria to support development of new preference-based measures. Criteria covering 22 different aspects related to item selection for preference-based measures are presented. These include criteria related to how items are phrased to ensure accurate completion, the coverage of items in terms of range of domains as well as focus on current outcomes and whether items are suitable for valuation. The criteria are aimed at supporting the development of new preference-based measures with discussion to ensure that even where there is conflict between criteria, issues have been considered at the item selection stage. This would minimize problems at valuation stage by harmonizing established criteria and expanding lists to reflect the unique characteristics of preference-based measures.
偏好量表允许患者报告他们的健康水平，然后使用来自代表性一般人群样本的偏好权重对这些反应进行评分，用于成本效用分析。新偏好量表的开发过程应确保选择有效的项目来反映量表中包含的感兴趣的构建，并适合用于偏好 elicitation 练习。对现有的患者报告结局测量（PROM）开发标准进行了审查，并考虑了其他因素，以制定支持新偏好量表开发的标准。提出了涵盖与偏好量表的项目选择相关的 22 个不同方面的标准。这些标准包括与如何措辞项目以确保准确完成相关的标准，项目在域范围方面的涵盖程度以及对当前结果的关注，以及项目是否适合估值。这些标准旨在支持新偏好量表的开发，并进行讨论，以确保即使在标准之间存在冲突的情况下，也已在项目选择阶段考虑了这些问题。这将通过协调既定标准和扩展清单来反映偏好量表的独特特征，从而最小化估值阶段的问题。
