目的 本研究的目的是评估 KIDSCREEN-27 问卷的结构和跨文化有效性。方法 KIDSCREEN 工具的 27 项版本源自较长的 52 项版本，并在一项横断面调查中对 13 个欧洲国家的 8-18 岁年轻人进行了调查。使用多特征多项目分析、探索性和验证性因素分析以及 Rasch 分析来测试结构效度和跨文化效度。 Zumbo 的逻辑回归方法用于评估各国的差异项目功能 (DIF)。使用 Cronbach's alpha 评估可靠性。 结果 从 n = 22,827 名受访者中获得答复（答复率为 68.9%）。对于来自所有国家的合并样本，采用 Procrustean 旋转的探索性因子分析揭示了五因子结构，可以解释 56.9% 的方差。验证性因子分析表明模型拟合可接受（RMSEA = 0.068，CFI = 0.960）。确认了所有维度的一维性（INFIT：0.81-1.15）。 13 个国家的差异项目功能 (DIF) 结果显示，5 个项目呈现统一的 DIF，而 10 个项目呈现不均匀的 DIF。可靠性是可以接受的（各个维度的 Cronbach α = 0.78-0.84）。 结论 有大量证据表明 KIDSCREEN-27 在所研究的国家中具有跨文化等效性，并且因子结构在各个国家中具有高度可复制性。需要进一步的研究来根据 DIF 结果纠正分数。 KIDSCREEN-27 是一种新的简短且有前途的工具，可用于临床和流行病学研究。
Ojectives The aim of this study is to assess the structural and cross-cultural validity of the KIDSCREEN-27 questionnaire.Methods The 27-item version of the KIDSCREEN instrument was derived from a longer 52-item version and was administered to young people aged 8-18 years in 13 European countries in a cross-sectional survey. Structural and cross-cultural validity were tested using multitrait multi-item analysis, exploratory and confirmatory factor analysis, and Rasch analyses. Zumbo's logistic regression method was applied to assess differential item functioning (DIF) across countries. Reliability was assessed using Cronbach's alpha.Results Responses were obtained from n = 22,827 respondents (response rate 68.9%). For the combined sample from all countries, exploratory factor analysis with procrustean rotations revealed a five-factor structure which explained 56.9% of the variance. Confirmatory factor analysis indicated an acceptable model fit (RMSEA = 0.068, CFI = 0.960). The unidimensionality of all dimensions was confirmed (INFIT: 0.81-1.15). Differential item functioning (DIF) results across the 13 countries showed that 5 items presented uniform DIF whereas 10 displayed non-uniform DIF. Reliability was acceptable (Cronbach's alpha= 0.78-0.84 for individual dimensions).Conclusions There was substantial evidence for the cross-cultural equivalence of the KIDSCREEN-27 across the countries studied and the factor structure was highly replicable in individual countries. Further research is needed to correct scores based on DIF results. The KIDSCREEN-27 is a new short and promising tool for use in clinical and epidemiological studies.
