This study aimed to develop a scale for respiratory infection prevention and control self-efficacy (R-PACS) to measure self-efficacy in the prevention and control of the spread of respiratory infections among adults and to confirm the applicability of the developed scale by testing its validity and reliability.
This methodological study was conducted in two phases. During the first phase, the R-PACS scale was developed after conducting a thorough literature review, content validity, and a pilot test. In the second phase, its validity and reliability were verified against 210 university students in Korea. The criterion validity of the developed R-PACS scale was tested using the correlation with resilience scale. Item analysis, explanatory factor analysis, and convergent and discriminant validity analyses were conducted in order to verify construct validity. Furthermore, Cronbach's α was used to verify internal consistency reliability.
The final version of the R-PACS scale comprises 4 factors and 16 items rated on a 5-point Likert scale. Higher scores are interpreted as higher levels of self-efficacy in the prevention and control of respiratory infection. The R-PACS scale exhibited good content validity, construct validity, criterion validity, and reliability. The correlation coefficient of the four factors was ≥.4, confirming the validity of item convergence; meanwhile, the Cronbach's α coefficient for the final 16 items of the developed scale was 0.923, verifying reliability. This scale consists of four factors: "environmental management", "contact restrictions", "general infection prevention and control", and "early detection".
The applicability of the R-PACS scale exhibited acceptable validity and reliability. This scale can be utilized to assess and evaluate the degree of self-efficacy in the prevention and control of respiratory infections among adults. Data obtained using this scale can be utilized for preparing health behavior change and health promotion programs, and practical policies for preventing respiratory infections.
本研究旨在开发一种呼吸道感染预防与控制自我效能量表（R - PACS），以测量成年人在预防和控制呼吸道感染传播方面的自我效能，并通过测试其效度和信度来确认所开发量表的适用性。
本方法学研究分两个阶段进行。在第一阶段，通过全面的文献综述、内容效度评估和预试验，开发了R - PACS量表。在第二阶段，针对韩国的210名大学生验证了其效度和信度。使用与复原力量表的相关性来测试所开发的R - PACS量表的效标效度。为了验证结构效度，进行了项目分析、解释性因素分析以及收敛效度和区分效度分析。此外，使用Cronbach's α来验证内部一致性信度。
R - PACS量表的最终版本包括4个因素和16个项目，采用5点李克特量表评分。分数越高，表明在预防和控制呼吸道感染方面的自我效能水平越高。R - PACS量表表现出良好的内容效度、结构效度、效标效度和信度。四个因素的相关系数≥0.4，证实了项目收敛的有效性；同时，所开发量表最终16个项目的Cronbach's α系数为0.923，验证了信度。该量表由四个因素组成：“环境管理”、“接触限制”、“一般感染预防与控制”和“早期检测”。
R - PACS量表的适用性表现出可接受的效度和信度。该量表可用于评估成年人在预防和控制呼吸道感染方面的自我效能程度。使用该量表获得的数据可用于制定健康行为改变和健康促进计划，以及预防呼吸道感染的实际政策。
