The aim of this study was to examine the psychometric characteristics of the childhood health assessment questionnaire-disability index (CHAQ-DI). Seventy-six patients with juvenile idiopathic arthritis (JIA), age range 4.8-15.8 years, completed a CHAQ questionnaire one or more times. In total, 321 CHAQ questionnaires were available for analysis. Factor analysis and correlation were used to analyse the data. The analysis indicated that 12 items could be removed from the original 30 items of the CHAQ-DI. Also the addition of "aids and assistance" to the overall scoring method of the CHAQ-DI did not contribute to the overall measuring concept of the CHAQ-DI. The psychometric characteristics of the CHAQ-DI could be improved by removing 12 items from the original 30 items. Moreover, a simple scoring method, without the addition of aids and assistance to the total CHAQ-DI improves sensitivity to change of the CHAQ-DI.
本研究旨在检验儿童健康评估问卷残疾指数（CHAQ-DI）的心理测量特征。76例幼年特发性关节炎（JIA）患者，年龄范围为4.8至15.8岁，完成了一次或多次CHAQ问卷。总共321份CHAQ问卷可供分析。采用因子分析和相关性分析数据。分析表明，CHAQ-DI最初的30项中有12项可以删除。此外，在CHAQ-DI的总体评分方法中增加“辅助器具和协助”对CHAQ-DI的总体测量概念没有贡献。通过从最初的30项中删除12项，可以改善CHAQ-DI的心理测量特征。此外，一种简单的评分方法，即在CHAQ-DI总分中不增加辅助器具和协助，可提高CHAQ-DI对变化的敏感性。
