BACKGROUND

The pediatric quality of life (QoL) questionnaire, the child-rated Kid-KINDL, has wording effects. However, no studies have examined for its parallel questionnaire, the parent-proxy Kid-KINDL. This study aimed to examine the psychometric properties and wording effects of the parent-proxy Kid-KINDL.

METHODS

Parents with 8- to 12-year-old children (n = 247) completed the parent-proxy Kid-KINDL, 83 of them completed it again 7-14 days later, and 241 of their children completed the child-rated Kid-KINDL. Internal consistency was examined using Cronbach's α; test-retest reliability and concurrent validity, using Pearson correlation coefficients (r); construct validity and wording effects, using confirmatory factor analyses (CFAs).

RESULTS

The internal consistency of the parent-proxy Kid-KINDL total score was acceptable (α = .86). Test-retest reliability (r = .33-.60) and concurrent validity (r = .27-.42) were acceptable or nearly acceptable for all subscales and the total score. The CFA models simultaneously accounting for QoL traits and wording effects had satisfactory fit indices, and outperformed the model accounting only for QoL traits. However, four subscales had unsatisfactory internal consistency, which might be attributable to wording effects.

CONCLUSION

When children are unable to complete a QoL questionnaire, the parent-proxy Kid-KINDL can substitute with all due cautions to wording effects and inconsistent reliability among different raters.

背景

儿童生活质量（QoL）问卷，即儿童自评的儿童生活质量问卷（Kid-KINDL），存在措辞效应。然而，尚无研究对其平行问卷——家长代理版儿童生活质量问卷（Kid-KINDL）进行考察。本研究旨在考察家长代理版Kid-KINDL的心理测量学特性及措辞效应。

方法

有8至12岁孩子的家长（n = 247）完成家长代理版Kid-KINDL，其中83人在7至14天后再次完成该问卷，他们的241名孩子完成儿童自评的Kid-KINDL。使用Cronbach's α检验内部一致性；使用Pearson相关系数（r）检验重测信度和同时效度；使用验证性因素分析（CFA）检验结构效度和措辞效应。

结果

家长代理版Kid-KINDL总分的内部一致性可以接受（α = 0.86）。所有分量表及总分的重测信度（r = 0.33 - 0.60）和同时效度（r = 0.27 - 0.42）可以接受或接近可接受。同时考虑生活质量特征和措辞效应的CFA模型具有令人满意的拟合指数，且优于仅考虑生活质量特征的模型。然而，有四个分量表的内部一致性不令人满意，这可能归因于措辞效应。
