目的：研究瑞典版的儿科生活质量量表（PedsQL）4.0通用核心量表在一般儿童populationinSweden.Methods：PedsQL形式分发给2403名学童和888名家长在两个不同的学校设置的心理测量性能。信度和效度进行了研究，自我报告和代理报告，完整的形式和简短的形式。结果：所有量表均具有重测信度，内部一致性信度α值均大于0.70，但只有一个量表（自陈简表：社会功能）的α值大于0.70。儿童与父母的一致性为低至中等。四因素结构的PedsQL和因子不变性跨性别亚组的自我报告表和代理短的形式，而模型拟合指数建议改善几个代理全形式scales.Conclusion：瑞典PedsQL 4.0通用核心量表是一个可靠和有效的工具，健康相关的生活质量（HRQoL）评估在瑞典儿童人群。但是，应谨慎使用代理完整表格。该研究还支持继续使用PedsQL作为四因素模型，能够揭示男孩和女孩之间有意义的HRQoL差异。
Aim:To study the psychometric performance of the Swedish version of the Pediatric Quality of Life Inventory (PedsQL) 4.0 generic core scales in a general child population in Sweden.Methods:PedsQL forms were distributed to 2403 schoolchildren and 888 parents in two different school settings. Reliability and validity was studied for self-reports and proxy reports, full forms and short forms. Confirmatory factor analysis tested the factor structure and multigroup confirmatory factor analysis tested measurement invariance between boys and girls.Results:Test-retest reliability was demonstrated for all scales and internal consistency reliability was shown with alpha value exceeding 0.70 for all scales but one (self-report short form: social functioning). Child-parent agreement was low to moderate. The four-factor structure of the PedsQL and factorial invariance across sex subgroups were confirmed for the self-report forms and for the proxy short form, while model fit indices suggested improvement of several proxy full-form scales.Conclusion:The Swedish PedsQL 4.0 generic core scales are a reliable and valid tool for health-related quality of life (HRQoL) assessment in Swedish child populations. The proxy full form, however, should be used with caution. The study also support continued use of the PedsQL as a four-factor model, capable of revealing meaningful HRQoL differences between boys and girls.
