背景
哮喘是一种常见于儿童的慢性疾病，意外的哮喘发作和/或日常自我管理的负担会威胁他们的生活质量 (QOL)。由于某些慢性疾病使孩子难以完成正常的发育任务，孩子获得成就感的机会可能会减少。本研究调查了日本学龄哮喘儿童生活质量问卷第 3 版 (JSCA-QOL v.3) 的信度和效度。该问卷包括“哮喘发作触发因素”、“日常生活变化”、“家庭支持”、“日常生活满意度”和“限制参与日常活动”五个领域的 25 个项目，采用 5 点李克特量表格式，以及一个汇总量表。
方法
本研究对日本 2,425 名 10 至 18 岁患有哮喘的儿童进行了调查。各领域的内部一致性信度用Cronbach's alpha信度系数考察，重测信度用Spearman相关系数考察。使用最大似然提取和 promax 旋转进行因子分析，进行因子有效性。使用SPSS 12.0J进行数据分析。
结果
最终有效回复数为2097条（有效数据率为86.5%）。 “哮喘发作触发因素”、“日常生活的改变”、“家庭支持”、“日常生活满意度”和“参与日常活动的限制”显示出较高的内部一致性（Cronbach's alpha = 0.66-0.86）以及良好的重测信度（Spearman's rho = 0.60，p < 0.01）。因子效度是适当的（KMO 值 = 0.90），因为可以想象，从因子分析中提取的五个因子将与我们的假设中的相同并支持建设性效度。此外，汇总量表与 QOL 总分之间存在良好的相关性（Spearman's rho = 0.58，p < 0.01）。
结论
本研究表明，JSCA-QOL v.3 是一种可靠且有效的测量工具，可用于适当评估学龄哮喘儿童的生活质量。由于JSCA-QOL v.3可以在大约10分钟内轻松完成，因此可以通过在门诊持续使用来作为医疗结果的有效评估工具。 JSCA-QOL v.3 允许医疗服务提供者帮助患有哮喘的学龄儿童完成其发育任务。
BACKGROUND
Asthma is a chronic disease prevalent in children which threatens their quality of life (QOL) through unexpected asthma attacks and/or the burden of daily self-management. As some conditions of chronic illness make it difficult for a child to accomplish normal developmental tasks, there may be fewer opportunities for the child to obtain a sense of achievement. This study investigated the reliability and validity of the Quality of Life Questionnaire for Japanese School-aged Children with Asthma Version 3 (JSCA-QOL v.3). This questionnaire includes 25 items with a 5-point Likert Scale format over five domains: "asthma attack triggers", "change in daily life", "family support", "satisfaction with daily life" and "restriction in participating in daily activities", and one summary scale.
METHODS
In the present study, 2,425 children with asthma aged from 10 to 18 years were investigated in Japan. The internal consistency reliability of each domain was investigated with Cronbach's alpha reliability coefficient, and test-retest reliability with Spearman's correlations coefficient. Factorial validity by factor analysis using maximum-likelihood extraction with promax rotation was performed. Data analysis was performed using SPSS 12.0J.
RESULTS
The final number of effective replies was 2,097 (the rate of effective data was 86.5%). "Asthma attack triggers", "change in daily life", "family support", "satisfaction with daily life" and "restriction in participating in daily activities" showed a high internal consistency (Cronbach's alpha = 0.66-0.86) as well as good test-retest reliability (Spearman's rho = 0.60, p < 0.01). The factorial validity was appropriate (KMO value = 0.90), because it was conceivable that the five factors extracted from factor analysis would be the same as in our hypothesis and support constructive validity. In addition, there was good correlation between the summary scale and the total QOL score (Spearman's rho = 0.58, p < 0.01).
CONCLUSIONS
The present study showed that the JSCA-QOL v.3 is a reliable and valid measurement tool that can be used to appropriately assess QOL in school-aged children with asthma. As the JSCA-QOL v.3 can be easily completed in about 10 minutes, it can contribute as an efficient evaluation tool of the outcome of medical treatment through continual utilization in the outpatient clinic. The JSCA-QOL v.3 allows a health provider to help school-aged children with asthma to achieve their developmental tasks.
