This study assesses the reliability and validity of the European KIDSCREEN-52 generic health-related quality of life (HRQoL) questionnaire for children and adolescents.
The KIDSCREEN-52, which measures HRQoL in 10 dimensions, was administered to a representative sample of 22,827 children and adolescents (8 to 18 years) in 13 European countries. Psychometric properties were assessed using the Classical Test Theory approach, Rasch analysis, and structural equation modeling (SEM). A priori expected associations between KIDSCREEN scales and sociodemographic and health-related factors were examined. Test-retest reliability was assessed in 10 countries.
For the overall sample, Cronbach's alpha values ranged from 0.77 to 0.89. Scaling success (Multitrait Analysis Program) was >97.8% for all dimensions and Rasch analysis item fit (INFITmsq) ranged from 0.80 to 1.27. The intraclass correlation coefficients ranged from 0.56 to 0.77. No sizeable differential item functioning (DIF) was found by age, sex or health status. Four items showed DIF across countries. The specified SEM fitted the data well (root mean square error of approximation: 0.06, comparative fit index: 0.98). Correlation coefficients between Pediatric Quality of Life Inventory, Child Health and Illness Profile-Adolescent Edition, and Youth Quality of Life Instrument scales and KIDSCREEN dimensions assessing similar constructs were moderate for those (r = 0.44 to 0.61). Statistically significant differences between children with and without physical and mental health problems (Children with Special Health Care Needs screener: d = 0.17 to 0.42, Strengths and Difficulties Questionnaire: d = 0.32 to 0.72) were found in all dimensions. All dimensions showed a gradient according to socioeconomic status.
The KIDSCREEN-52 questionnaire has acceptable levels of reliability and validity. Further work is needed to assess longitudinal validity and sensitivity to change.
本研究评估欧洲儿童青少年健康相关生活质量（HRQoL）问卷KIDSCREEN - 52的信度和效度。
KIDSCREEN - 52用于测量10个维度的HRQoL，对13个欧洲国家的22827名8至18岁儿童和青少年的代表性样本进行了问卷调查。使用经典测试理论方法、拉施分析和结构方程模型（SEM）评估心理测量特性。检验了KIDSCREEN量表与社会人口统计学和健康相关因素之间的先验预期关联。在10个国家评估了重测信度。
对于总体样本，克朗巴哈系数值范围为0.77至0.89。所有维度的量表编制成功率（多特质分析程序）>97.8%，拉施分析项目拟合度（INFITmsq）范围为0.80至1.27。组内相关系数范围为0.56至0.77。未发现年龄、性别或健康状况导致的明显差异项目功能（DIF）。有4个项目在不同国家间显示出DIF。指定的SEM与数据拟合良好（近似均方根误差：0.06，比较拟合指数：0.98）。儿童生活质量量表、儿童健康与疾病概况 - 青少年版以及青少年生活质量量表与评估相似结构的KIDSCREEN维度之间的相关系数适中（r = 0.44至0.61）。在所有维度中，有心理健康问题和无心理健康问题的儿童之间存在统计学显著差异（特殊医疗需求儿童筛查量表：d = 0.17至0.42，优势与困难问卷：d = 0.32至0.72）。所有维度均显示出根据社会经济地位的梯度变化。
KIDSCREEN - 52问卷具有可接受的信度和效度水平。需要进一步开展工作以评估纵向效度和对变化的敏感性。
