背景：基于自我报告以及父母的代理报告，可以使用几种工具来评估儿童与健康相关的生活质量（HRQOL）。先前的研究发现，在自我和代理报告之间只有低到中度的一致性，但是很少有研究明确比较两者的心理测量品质。这项研究比较了HRQOL KINDL-R-R问卷调查的儿童和青少年的自我报告和父母报告版本的可靠性，阶乘有效性以及收敛性和已知的群体有效性。对儿童和青少年的调查（Kiggs），6,813名11至17岁的儿童和青少年完成了Kindl-R Generic HRQOL仪器他们的父母回答了Kindl代理版本（既有纸和铅笔版本）。获得了Cronbach的α和验证性因子分析模型（线性结构方程模型）。通过计算Pearson的强度和困难问卷的相关系数来评估收敛性和判别有效性。研究了家庭社会经济地位较低的肥胖儿童和儿童的已知组差异（ANOVA）。分子：父母的报告的总分（0.86 vs. 0.83）和大多数亚核心的Cronbach的Alpha值略高。验证性因素分析表明，父母（RMSEA = 0.07）和儿童报告（RMSEA = 0.06）的Kindl的六维测量模型可接受拟合。两种版本的阶乘不变性在负载模式，项目错误和潜在概念之间的协方差方面不存在。但是，差异的幅度很小。在优势和困难问卷中，父报告版本的收敛有效性略高（r = 0.44-0.63 vs. r = 0.33-0.59）。关于已知组有效性的没有明显的差异。判断：我们的研究表明，父母的替代报告和儿童自我报告对孩子的HRQOL略有差异，对感知，评估以及每个组的情感共鸣是如何结构和内部的。持续的。总体而言，父母报告的可靠性稍高，因此受到较小样本的检查。关于测量的有效性，没有任何版本普遍优越。只要有可能，应通过两个信息来源测量儿童HRQOL。
Background: Several instruments are available to assess children's health-related quality of life (HRQoL) based on self reports as well as proxy reports from parents. Previous studies have found only low-to-moderate agreement between self and proxy reports, but few studies have explicitly compared the psychometric qualities of both. This study compares the reliability, factorial validity and convergent and known group validity of the self-report and parent-report versions of the HRQoL KINDL-R questionnaire for children and adolescents.Methods: Within the nationally representative cross-sectional German Health Interview and Examination Survey for Children and Adolescents (KiGGS), 6,813 children and adolescents aged 11 to 17 years completed the KINDL-R generic HRQoL instrument while their parents answered the KINDL proxy version (both in paper-and-pencil versions). Cronbach's alpha and confirmatory factor-analysis models (linear structural equation model) were obtained. Convergent and discriminant validity were assessed by calculating the Pearson's correlation coefficient for the Strengths and Difficulties Questionnaire. Known-groups differences were examined (ANOVA) for obese children and children with a lower familial socio-economic status.Results: The parent reports achieved slightly higher Cronbach's alpha values for the total score (0.86 vs. 0.83) and most sub-scores. Confirmatory factor analysis revealed an acceptable fit of the six-dimensional measurement model of the KINDL for the parent (RMSEA = 0.07) and child reports (RMSEA = 0.06). Factorial invariance across the two versions did not hold with regards to the pattern of loadings, the item errors and the covariation between latent concepts. However the magnitude of the differences was rather small. The parent report version achieved slightly higher convergent validity (r = 0.44-0.63 vs. r = 0.33-0.59) in the Strengths and Difficulties Questionnaire. No clear differences were observed for known-groups validity.Conclusion: Our study showed that parent proxy reports and child self reports on the child's HRQoL slightly differ with regards to how the perceptions, evaluations and possibly the affective resonance of each group are structured and internally consistent. Overall, the parent reports achieved slightly higher reliability and thus are favoured for the examination of small samples. No version was universally superior with regards to the validity of the measurements. Whenever possible, children's HRQoL should be measured via both sources of information.
