This study aims to develop the Parental Inhaled Medication Literacy Scale for School-Aged Children with Asthma (PIMLS-SA) and to evaluate its reliability and validity.
From December 2024 to March 2025, 450 parents of school-age children with asthma were recruited from a tertiary children's hospital in Chongqing to evaluate the reliability and validity of the instrument. The participants were aged 28-69 years (39.37 ± 5.44). Data were collected using a general information form and the PIMLS-SA scale. The scale was developed based on the concept of medication literacy and the Knowledge-Attitude-Practice (KAP) model, and its initial draft was informed by a literature review, Delphi expert consultation, and a pretest. Content validity was determined through consultation with 15 experts in respiratory medicine, pediatric nursing, pharmacy, and research methodology. Data analyses included correlation analysis and Cronbach's α coefficient to evaluate reliability, and both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to examine construct validity.
The Parental Inhaled Medication Literacy Scale for School-Aged Children with Asthma (PIMLS-SA) was confirmed to be composed of four domains and eight factors, encompassing a total of 32 items. Specifically, the knowledge domain included 11 items, the medication beliefs domain had 4 items, the skill domain involved 5 items, and the practice domain included 12 items. The results showed that the Cronbach's α coefficient of PIMLS-SA was 0.856, and for each domain ranged from 0.732 to 0.878; the split-half reliability coefficient of PIMLS-SA was 0.751, and for each domain ranged from 0.613 to 0.822. In evaluating validity, the content validity index (CVI) for individual items ranged from 0.87 to 1.00, and the scale-level content validity index (S-CVI) was 0.94. The correlations between domains and the total scale ranged from 0.451 to 0.778, and inter-domain correlations ranged from 0.148 to 0.398 (P < 0.05). Confirmatory factor analysis results showed that the model fitted well (χ/df = 2.136, RMSEA = 0.071, SRMR = 0.021, CFI = 0.923, GFI = 0.952, AGFI = 0.943, NFI = 0.951, TLI = 0.855). The convergent validity and discriminant validity were both good.
The scale has acceptable content validity, construct validity, and good reliability. It can be used to evaluate the level of inhaled medication literacy among parents of school-aged children with asthma in China.
本研究旨在开发适用于学龄期哮喘儿童的家长吸入药物知识量表（PIMLS-SA），并评估其信效度。
2024年12月至2025年3月，从重庆某三级儿童医院招募了450名学龄期哮喘儿童的家长，以评估该量表的信效度。参与者年龄在28 - 69岁之间（39.37 ± 5.44）。通过一般信息表和PIMLS-SA量表收集数据。该量表基于药物知识概念和知识-态度-行为（KAP）模型开发，其初稿参考了文献综述、德尔菲专家咨询和预测试。通过与15名呼吸医学、儿科护理、药学和研究方法学专家协商确定内容效度。数据分析包括相关性分析和Cronbach's α系数以评估信度，以及探索性因子分析（EFA）和验证性因子分析（CFA）以检验结构效度。
适用于学龄期哮喘儿童的家长吸入药物知识量表（PIMLS-SA）被确认为由四个领域和八个因子组成，共32个条目。具体而言，知识领域包括11个条目，用药信念领域有4个条目，技能领域涉及5个条目，行为领域包括12个条目。结果显示，PIMLS-SA的Cronbach's α系数为0.856，各领域范围为0.732至0.878；PIMLS-SA的分半信度系数为0.751，各领域范围为0.613至0.822。在评估效度时，单个条目的内容效度指数（CVI）范围为0.87至1.00，量表水平的内容效度指数（S-CVI）为0.94。各领域与总量表之间的相关性范围为0.451至0.778，领域间相关性范围为0.148至0.398（P < 0.05）。验证性因子分析结果表明模型拟合良好（χ/df = 2.136，RMSEA = 0.071，SRMR = 0.021，CFI = 0.923，GFI = 0.952，AGFI = 0.943，NFI = 0.951，TLI = 0.855）。收敛效度和区分效度均良好。
该量表具有可接受的内容效度、结构效度和良好的信度。可用于评估我国学龄期哮喘儿童家长的吸入药物知识水平。
