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.
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.
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).
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.
哮喘是一种在儿童中普遍存在的慢性疾病，通过意外的哮喘发作和/或日常自我管理负担威胁着他们的生活质量（QOL）。由于某些慢性病状况使儿童难以完成正常的发育任务，儿童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25个项目，采用5点李克特量表形式，涵盖五个领域：“哮喘发作诱因”、“日常生活变化”、“家庭支持”、“对日常生活的满意度”和“参与日常活动的限制”，以及一个总结量表。
在本研究中，对日本2425名10至18岁的哮喘儿童进行了调查。使用Cronbach's alpha信度系数调查每个领域的内部一致性信度，使用Spearman相关系数调查重测信度。采用最大似然提取和斜交旋转的因子分析进行结构效度分析。使用SPSS 12.0J进行数据分析。
有效回复的最终数量为2097份（有效数据率为86.5%）。“哮喘发作诱因”、“日常生活变化”、“家庭支持”、“对日常生活的满意度”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）。结构效度合适（KMO值 = 0.90），因为可以想象从因子分析中提取的五个因子与我们的假设相同，并支持构想效度。此外，总结量表与总生活质量得分之间存在良好的相关性（Spearman's rho = 0.58，p < 0.01）。
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大约10分钟就能轻松完成，通过在门诊持续使用，它可以作为一种有效的医疗治疗效果评估工具。JSCA-QOL v.3使医疗服务提供者能够帮助学龄哮喘儿童完成他们的发育任务。
