This study assesses the feasibility, reliability and validity of the Child Health Questionnaire-Parent Form (CHQ-PF50), consisting of 11 multi-item scales covering the physical, emotional and social well-being of children. The Health Utilities Index mark 2 (HUI2) was selected for comparison. Parents of 467 Dutch schoolchildren (age 5-13) were sent CHQ and HUI questionnaires. A subgroup of 79 parents of children aged 10-11 were sent a retest after 2 weeks. Feasibility: 78% response with few missing/non-unique CHQ-answers (<1%). Internal consistency: Cronbach's alphas of.39-.96 (mean.72). Item-own scale correlations were higher than item-other scale correlations. Test-retest ICCs were statistically significant for all but two CHQ scales (ICCs.31-.84). Test-retest CHQ-scale means did not show statistically significant differences except for one scale ("Behavior").
the CHQ-scales, with one exception, correlated better with predefined parallel HUI domains (ICCs.26-.53), than with non-parallel domains. Six CHQ scales discriminated clearly between children with and without chronic conditions and three scales discriminated between high and low medical consumption. This was at least equivalent to the discriminative ability of the HUI2 in this study. Additional studies of test-retest reliability and responsiveness to change of the CHQ in varied populations are needed. From the present study and literature data on other (clinical) populations we conclude that psychometric properties of CHQ-based health status measurement justify application in pediatric outcome studies, in addition to clinical measures.
本研究评估了儿童健康问卷家长版（CHQ - PF50）的可行性、可靠性和有效性，该问卷由11个多项目量表组成，涵盖儿童的身体、情感和社会福祉。选择健康效用指数2（HUI2）作为比较对象。向467名荷兰学童（5 - 13岁）的家长发放了CHQ和HUI问卷。79名10 - 11岁儿童的家长子组在2周后接受了重测。可行性：78%的回复率，CHQ答案中几乎没有缺失/不唯一的情况（<1%）。内部一致性：克朗巴哈系数为0.39 - 0.96（平均0.72）。项目与自身量表的相关性高于项目与其他量表的相关性。除两个CHQ量表外，所有量表的重测组内相关系数均具有统计学意义（组内相关系数为0.31 - 0.84）。除一个量表（“行为”）外，CHQ量表重测均值未显示出统计学上的显著差异。
除一个例外，CHQ量表与预定义的平行HUI领域的相关性（组内相关系数为0.26 - 0.53）优于与非平行领域的相关性。六个CHQ量表能清晰地区分患有和未患有慢性病的儿童，三个量表能区分高医疗消费和低医疗消费的儿童。这至少等同于本研究中HUI2的区分能力。需要对CHQ在不同人群中的重测可靠性和对变化的反应性进行更多研究。从本研究以及关于其他（临床）人群的文献数据中我们得出结论，基于CHQ的健康状况测量的心理测量特性证明了其除临床测量外，在儿科结局研究中的应用价值。
