BACKGROUND
Knowledge about psychometric properties of the Pediatric Quality of Life Inventory (PedsQL) in the Netherlands is limited and Dutch reference data are lacking. Aim of the current study is to collect Dutch reference data of the PedsQL and subsequently assess reliability, socio-demographic within-group differences and construct validity.
METHODS
In this study the PedsQL was administered to Dutch children aged 5 to 18 years. A socio-demographic questionnaire was completed as well. The sample consisted of three age groups: 5-7 years (parent proxy report), 8-12 years and 13-18 years (child self report). Analysis was performed with SPSS 16.0.2. A reliability analysis was done using Cronbach's alpha coefficient. Socio-demographic within-group differences were assessed by means of an ANOVA with post hoc Bonferroni correction and t-tests. Subsequently, construct validity was determined by t-tests and effect sizes.
RESULTS
For 496 children PedsQL reference data were collected. PedsQL total scores were 84.18 (group 5-7), 82.11 (group 8-12) and 82.24 (group 13-18). Internal consistency coefficients ranged from .53 to .85. Socio-demographic within-group differences demonstrated that, in group 8-12, children of parents born in the Netherlands had significantly lower scores on several PedsQL subscales, compared to children of parents born in another country. With respect to construct validity, healthy children of group 5-7 and 13-18 scored significantly higher than children with a chronic health condition on all subscales, except for emotional functioning. In group 5-7, the PedsQL total score for healthy children was 85.31, whereas the same age group with a chronic health condition scored 78.80. Effect sizes in this group varied from 0.58 to 0.88. With respect to group 13-18, healthy children obtained a PedsQL total score of 83.14 and children suffering from a chronic health condition 77.09. Effect sizes in this group varied from 0.45 to 0.67. No significant differences were found in group 8-12 regarding health.
CONCLUSION
The Dutch version of the PedsQL has adequate psychometric properties and can be used as a health related quality of life instrument in paediatric research in the Netherlands.
背景
荷兰对儿科生活质量问卷（PedsQL）的心理测量特性知之甚少，也缺乏荷兰参考数据。本研究的目的是收集荷兰 PedsQL 的参考数据，随后评估其信度、社会人口统计学组内差异和结构效度。
方法
本研究对 5 至 18 岁的荷兰儿童进行了 PedsQL 评估。还完成了一份社会人口学问卷。样本由三个年龄组组成：5-7 岁（父母代理报告）、8-12 岁和 13-18 岁（儿童自我报告）。使用 SPSS 16.0.2 进行分析。使用 Cronbach's alpha 系数进行信度分析。通过方差分析（事后 Bonferroni 校正和 t 检验）评估社会人口统计学组内差异。随后，通过 t 检验和效应大小确定结构效度。
结果
共收集了 496 名儿童的 PedsQL 参考数据。PedsQL 总分分别为 84.18（5-7 岁组）、82.11（8-12 岁组）和 82.24（13-18 岁组）。内部一致性系数范围为 0.53 至 0.85。社会人口统计学组内差异表明，在 8-12 岁组中，父母出生于荷兰的儿童在几个 PedsQL 子量表上的得分明显低于父母出生于其他国家的儿童。关于结构效度，5-7 岁和 13-18 岁健康儿童在所有子量表上的得分均显著高于患有慢性疾病的儿童，除了情绪功能。在 5-7 岁组中，健康儿童的 PedsQL 总分得分为 85.31，而患有慢性疾病的相同年龄组的得分为 78.80。该组的效应大小从 0.58 到 0.88 不等。对于 13-18 岁组，健康儿童的 PedsQL 总分为 83.14，患有慢性疾病的儿童为 77.09。该组的效应大小从 0.45 到 0.67 不等。8-12 岁组在健康方面没有发现显著差异。
结论
荷兰版 PedsQL 具有良好的心理测量特性，可作为荷兰儿科研究中的健康相关生活质量工具。
