This study aimed to provide population norms among children and adolescents in Chile using the EQ-5D-Y-3L questionnaire and to examine its feasibility and validity among body weight statuses.
This was a cross-sectional study in which 2204 children and adolescents (aged 8-18 years) from Chile completed a set of questionnaires providing sociodemographic, anthropometric and health-related quality of life (HRQoL) data using the five EQ-5D-Y-3L dimensions and its visual analogue scale (EQ-VAS). Descriptive statistics of the five dimensions and the EQ-VAS were categorized into body weight status groups for the EQ-5D-Y-3L population norms. The ceiling effect, feasibility and discriminant/convergent validity of the EQ-5D-Y-3L were tested.
The dimensions of the EQ-5D-Y-3L questionnaire presented more ceiling effects than the EQ-VAS. The validity showed that the EQ-VAS could discriminate among body weight statuses. However, the EQ-5D-Y-3L index (EQ-Index) demonstrated a non-acceptable discriminant validity. Furthermore, both the EQ-Index and the EQ-VAS presented an acceptable concurrent validity among weight statuses.
The normative values of the EQ-5D-Y-3L indicated its potential use as a reference for future studies. However, the validity of the EQ-5D-Y-3L for comparing the HRQoL among weight statuses could be insufficient.
本研究旨在为智利儿童和青少年提供 EQ-5D-Y-3L 问卷的人群正常值，并检验其在不同体重状况下的可行性和有效性。
这是一项横断面研究，共纳入 2204 名来自智利的 8-18 岁儿童和青少年，他们使用 EQ-5D-Y-3L 的五个维度及其视觉模拟量表（EQ-VAS）完成了一套问卷，提供了社会人口统计学、人体测量学和健康相关生活质量（HRQoL）数据。将五个维度和 EQ-VAS 的描述性统计数据按照体重状况分组，以制定 EQ-5D-Y-3L 的人群正常值。测试了 EQ-5D-Y-3L 的天花板效应、可行性和判别/收敛效度。
EQ-5D-Y-3L 问卷的各个维度比 EQ-VAS 呈现出更多的天花板效应。效度表明，EQ-VAS 可以区分不同的体重状况。然而，EQ-5D-Y-3L 指数（EQ-Index）表现出不可接受的判别效度。此外，EQ-Index 和 EQ-VAS 在体重状况方面均表现出可接受的同时效度。
EQ-5D-Y-3L 的正常值表明其可能作为未来研究的参考。然而，EQ-5D-Y-3L 在比较体重状况下的 HRQoL 方面的有效性可能不足。
