The self-reported KIDSCREEN-10 index (KS-10) is widely used to assess health-related quality of life (HRQoL) in children and adolescents, but psychometric evidence for its Mandarin Chinese version remains limited. This study evaluates its psychometric properties, develops a population-based norm, and establishes a norm-referenced scoring algorithm.
Data were collected from a two-wave cross-sectional survey across the Chinese Human Geography Regions (June 20-July 11, 2022). The sample included 3290 adolescents (ages 10-18; 51.5% female; 75.8% Han ethnic group) in their junior secondary education stage, obtained through convenience sampling (first wave) and multistage, stratified, cluster sampling (second wave). Psychometric properties were evaluated using the Rasch measurement method, and both a population-based norm and a norm-referenced scoring algorithm were developed and established.
Confirmatory factor analysis confirmed unidimensionality after two modifications. Rasch analysis demonstrated satisfactory psychometric performance, including an appropriate 5-category rating scale and strong goodness-of-fit. Minor local dependence was observed in a few item pairs, indicating slight unidimensionality violations. Both Rasch-generated reliability measures performed well. The person-item map showed acceptable matches and provided insights for further improvements. No substantial uniform differential item functioning was detected across 14 groups.
The Mandarin Chinese self-reported KS-10 demonstrates satisfactory psychometric properties and provides a concise measure of adolescent HRQoL. It is a user-friendly instrument suitable for routine school monitoring, large-scale population surveys, and clinical applications. The population-based norm and norm-referenced scoring algorithm support its broader application and promotion, and offer new insights for interpreting HRQoL sum scores.
自我报告的儿童青少年生活质量量表10项指标（KS - 10）被广泛用于评估儿童和青少年与健康相关的生活质量（HRQoL），但其中文版的心理测量学证据仍然有限。本研究评估其心理测量学特性，制定基于人群的常模，并建立常模参照评分算法。
数据来自于一项在中国人类地理区域进行的两波横断面调查（2022年6月20日至7月11日）。样本包括3290名处于初中教育阶段的青少年（年龄10 - 18岁；女性占51.5%；汉族占75.8%），通过便利抽样（第一波）和多阶段、分层、整群抽样（第二波）获得。使用拉施测量方法评估心理测量学特性，并制定和建立基于人群的常模和常模参照评分算法。
验证性因素分析在两次修改后确认了单维度性。拉施分析显示出令人满意的心理测量学性能，包括合适的5级评分量表和良好的拟合优度。在少数项目对中观察到轻微的局部依赖性，表明存在轻微的单维度性违反情况。两种基于拉施生成的信度测量都表现良好。人 - 项目图显示出可接受的匹配度，并为进一步改进提供了见解。在14个组中未检测到实质性的一致性差异项目功能。
中文版自我报告的KS - 10表现出令人满意的心理测量学特性，并提供了一种简洁的青少年HRQoL测量方法。它是一种用户友好的工具，适用于常规学校监测、大规模人群调查和临床应用。基于人群的常模和常模参照评分算法支持其更广泛的应用和推广，并为解释HRQoL总分提供了新的见解。
