BACKGROUND
In economic evaluations of care services for older adults health-related quality of life (QoL) measures such as the EQ-5D are increasingly replaced by the ICECAP-O and ASCOT, which cover a broader scope of QoL than health alone. Little is known about the content validity and feasibility of these measures. The purpose of this study was to explore the content validity and feasibility of the EQ-5D-3L, ICECAP-O and ASCOT in older adults.
METHODS
Ten older adults were purposively sampled using a maximum variation principle. Think-aloud and verbal probing techniques were used to identify response issues encountered during the interpretation of items and the selection of response options. We used constant comparative methods to analyse the data.
RESULTS
Two types of response issues were identified for various items in all three measures: interpretation issues and positive responses. Issues with the mapping of a response on one of the response options were least often encountered for the EQ-5D-3L items. Older adults considered the items of the ICECAP-O and ASCOT valuable though more abstract than the EQ-5D-3L.
CONCLUSIONS
Researchers who intend to use the EQ-5D, ICECAP-O or ASCOT in economic evaluations of care services for older adults, should be aware of the response issues that occur during the administration of these measures. Older adults perceived none of the measures as providing a comprehensive picture of their QoL. A preference from older adults for one of the measures depends on the extent to which the items reflect current personal concerns in life.
背景
在针对老年人护理服务的经济评估中，诸如欧洲五维度健康量表（EQ - 5D）等与健康相关的生活质量（QoL）测量工具正越来越多地被ICECAP - O和ASCOT所取代，后者所涵盖的生活质量范围比单纯的健康更广泛。对于这些测量工具的内容效度和可行性知之甚少。本研究的目的是探讨EQ - 5D - 3L、ICECAP - O和ASCOT在老年人中的内容效度和可行性。
方法
采用最大变异原则有目的地抽取了10名老年人作为样本。运用出声思考法和言语探查技术来识别在解释项目和选择反应选项过程中遇到的回答问题。我们使用持续比较法来分析数据。
结果
在所有三种测量工具的各个项目中识别出了两种类型的回答问题：解释问题和肯定回答。在EQ - 5D - 3L项目中，将回答映射到其中一个反应选项上的问题最少出现。老年人认为ICECAP - O和ASCOT的项目有价值，尽管比EQ - 5D - 3L更抽象。
结论
打算在老年人护理服务的经济评估中使用EQ - 5D、ICECAP - O或ASCOT的研究人员，应该意识到在实施这些测量工具过程中出现的回答问题。老年人认为没有一种测量工具能全面反映他们的生活质量。老年人对其中一种测量工具的偏好取决于项目反映当前个人生活关注点的程度。
