This study examined psychometric properties and feasibility issues surrounding child-reported asthma health status data.
In separate interviews, parents and children completed 3 visits. Child questionnaires were interviewer administered. The primary instrument was the Children's Health Survey for Asthma-Child Version, used to compute 3 scales (physical health, activities, and emotional health). The following were assessed: reliability (internal consistency and test-retest reliability), validity (general health status, symptom burden, and lung function), and feasibility (completion time, missing data, and inconsistent responses).
A total of 414 parent-child pairs completed the study (mean child age: 11.5 years). Reliability estimates for the activities and emotional health scales were > .70 in all but 1 age category; 5 of 9 age groups had acceptable internal consistency ratings (> or = .70) for the physical health scale. Cronbach's alpha tended to increase with child age. In general, test-retest correlations between forms and intraclass correlation coefficients were strong for all ages but tended to increase with child age. Correlations between forms ranged from .57 (7-year-old subjects, physical health) to .96 (14-year-old subjects, activities). Intraclass correlation coefficients ranged from .76 (13-year-old subjects, emotional health) to .94 (15-16-year-old subjects, physical health). Children with less symptom burden reported higher mean Children's Health Survey for Asthma-Child Version scores (indicating better health status) for each scale, at significant levels for nearly all age groups. Children's Health Survey for Asthma-Child Version completion times decreased from 12.9 minutes at age 7 to 6.9 minutes at age 13.
This research indicates that children with asthma as young as 7 may be dependable and valuable reporters of their health. Data quality tends to improve with age.
本研究探讨了儿童报告的哮喘健康状况数据的心理测量特性和可行性问题。
在单独的访谈中，父母和孩子完成了3次访视。儿童问卷由访谈者进行询问。主要工具是儿童哮喘健康调查儿童版，用于计算3个量表（身体健康、活动和情绪健康）。评估了以下内容：信度（内部一致性和重测信度）、效度（总体健康状况、症状负担和肺功能）和可行性（完成时间、缺失数据和不一致的回答）。
共有414对亲子完成了研究（儿童平均年龄：11.5岁）。除1个年龄组外，活动和情绪健康量表的信度估计值均大于0.70；9个年龄组中有5个年龄组的身体健康量表具有可接受的内部一致性评分（≥0.70）。克朗巴哈系数往往随着儿童年龄的增长而增加。一般来说，所有年龄组的不同版本之间的重测相关性和组内相关系数都很强，但往往随着儿童年龄的增长而增加。不同版本之间的相关性范围从0.57（7岁儿童，身体健康）到0.96（14岁儿童，活动）。组内相关系数范围从0.76（13岁儿童，情绪健康）到0.94（15 - 16岁儿童，身体健康）。症状负担较轻的儿童在每个量表上的儿童哮喘健康调查儿童版平均得分较高（表明健康状况较好），几乎所有年龄组的差异均具有统计学意义。儿童哮喘健康调查儿童版的完成时间从7岁时的12.9分钟降至13岁时的6.9分钟。
本研究表明，年仅7岁的哮喘儿童可能是其健康状况可靠且有价值的报告者。数据质量往往随着年龄的增长而提高。
