EQ-5D-5L 的开发是为了弥补 EQ-5D-3L 的高天花板效应和缺乏描述性的丰富性。我们评估了普通人群中 EQ-5D-5L 的心理测量特性。使用多阶段分层配额抽样方法从韩国普通人群中抽取了 600 名成年人。参与者完成了 EQ-5D-5L、EQ-5D-3L 和 SF-36v2。对一百名参与者进行了重新调查以进行可靠性评估。对 EQ-5D-5L 的天花板效应、已知群体构建有效性、收敛和判别有效性以及可靠性进行了评估。对 EQ-5D-5L 的所有维度（61.2%）回答“没问题”的参与者比例比 EQ-5D-3L（65.7%，p < 0.01）小，表明天花板效应降低。女性、老年人、低学历和低收入参与者更频繁地报告健康问题，表明已知群体构建效度。 EQ-5D-5L 的移动维度与身体成分得分 (|r| = 0.48) 的相关性高于 SF-36v2 的心理成分得分 (|r| = 0.25)，焦虑/抑郁维度与心理成分得分 (|r| = 0.45) 的相关性高于身体成分得分 (|r| = 0.34)，表明收敛效度和判别效度。 EQ-5D-5L指数的组内相关系数为0.75。EQ-5D-5L的上限效应比EQ-5D-3L更小，是衡量普通人群健康相关生活质量的有效且可靠的工具。
The EQ-5D-5L was developed to compensate for a high ceiling effect and lack of descriptive richness of the EQ-5D-3L. We evaluated psychometric properties of EQ-5D-5L in the general population.Six hundred of adults were sampled from the general population in South Korea using a multistage stratified quota sampling method. Participants completed the EQ-5D-5L, EQ-5D-3L, and SF-36v2. One hundred participants were resurveyed for reliability evaluation. The ceiling effect, known-groups construct validity, convergent and discriminant validity, and reliability of EQ-5D-5L were evaluated.A smaller proportion of participants answered 'no problem' to all dimensions of EQ-5D-5L (61.2 %) than EQ-5D-3L (65.7 %, p < 0.01), indicating a reduced ceiling effect. Female, elderly, low-educated, and low-income participants reported health problems more frequently, indicating known-groups construct validity. The mobility dimension of EQ-5D-5L was better correlated with the physical component score (|r| = 0.48) than the mental component score (|r| = 0.25) of the SF-36v2, and the anxiety/depression dimension was better correlated with mental component score (|r| = 0.45) than physical component score (|r| = 0.34), indicating convergent and discriminant validity. The intraclass correlation coefficient of EQ-5D-5L index was 0.75.The EQ-5D-5L has a smaller ceiling effect than the EQ-5D-3L and is a valid and reliable instrument to measure health-related quality of life in the general population.
