EQ-5D-Y is a generic measure of health status for children and adolescents aged 8-15 years. Originally, it has three levels of severity in each dimension (3L). This study aimed to develop a descriptive system of EQ-5D-Y with an increased number of severity levels and to test comprehensibility and feasibility.
The study was conducted in Germany, Spain, Sweden and the UK. In Phase 1, a review of existing instruments and focus group interviews were carried out to create a pool of possible labels for a modified severity classification. Participants aged 8-15 rated the severity of the identified labels in individual sorting and response scaling interviews. In Phase 2, preliminary 4L and 5L versions were constructed for further testing in cognitive interviews with healthy participants aged 8-15 years and children receiving treatment for a health condition.
In Phase 1, a total of 233 labels was generated, ranging from 37 (UK) to 79 labels (Germany). Out of these, 7 to 16 possible labels for each dimension in the different languages were rated in 255 sorting and response scaling interviews. Labels covered an appropriate range of severity on the health continuum in all countries. In Phase 2, the 5L version was generally preferred (by 68-88% of the participants per country) over the 4L version.
This multinational study has provided a version of the EQ-5D-Y with 5 severity levels in each dimension. This extended version (EQ-5D-Y-5L) requires testing its psychometric properties and its performance compared to that of the original EQ-5D-Y-3L.
EQ-5D-Y 是一种针对 8-15 岁儿童和青少年的健康状况通用衡量标准。最初，它在每个维度上都有三个严重程度等级（3L）。本研究旨在开发一个具有更多严重程度等级的 EQ-5D-Y 描述系统，并测试其可理解性和可行性。
该研究在德国、西班牙、瑞典和英国进行。在第 1 阶段，对现有工具进行了审查，并进行了焦点小组访谈，以创建一个用于改良严重程度分类的可能标签库。8-15 岁的参与者在个体分类和反应标度访谈中对确定标签的严重程度进行了评分。在第 2 阶段，初步构建了 4L 和 5L 版本，以便在认知访谈中进一步测试，访谈对象为 8-15 岁的健康参与者和正在接受健康状况治疗的儿童。
在第 1 阶段，共生成了 233 个标签，范围从英国的 37 个标签到德国的 79 个标签。在这些标签中，来自不同语言的每个维度有 7-16 个可能的标签在 255 次分类和反应标度访谈中进行了评分。在所有国家，标签都涵盖了健康连续体的适当严重程度范围。在第 2 阶段，5L 版本通常更受欢迎（每个国家的参与者中有 68%-88%更喜欢 5L 版本）。
这项多国家研究提供了一种每个维度有 5 个严重程度等级的 EQ-5D-Y 版本。这个扩展版本（EQ-5D-Y-5L）需要测试其心理测量特性及其与原始 EQ-5D-Y-3L 的性能比较。
