This study aimed to develop a scale for measuring infection prevention behavior of individuals and to verify its validity and reliability for the general population.
The scale items were selected using a literature review on the chain of infection and its content validity. There were 297 study participants, all of whom provided informed consent. Data were collected online from September 3 to September 8, 2020, using Google Survey in Korea. The scale's construct validity was verified through exploratory and confirmatory factor analyses, criterion validity was Pearson's Correlation, and reliability was tested using Cronbach's alpha.
Twelve items and three factors were selected after a factor and an exploratory factor analysis of 29 scale items. The three factors were pathogen blocking, transmission blocking, and immunity enhancement. A confirmatory factor analysis validated the model goodness of fit, and the convergent validity and discriminant validity of the scale were verified. The correlation coefficient with a scale for respiratory infection prevention practice was 0.69, thereby confirming the criterion validity of the scale. The reliability of the final scale (Cronbach's alpha) was 0.86.
This scale is reflective of the social features of the Korean adult population, and it is easy and concise to be administered to general public, making it useful for subsequent studies on infection prevention.
本研究旨在开发一种用于测量个体感染预防行为的量表，并验证其在普通人群中的有效性和可靠性。
通过对感染链及其内容效度的文献综述来选择量表项目。共有297名研究参与者，他们均提供了知情同意书。2020年9月3日至9月8日，在韩国使用谷歌调查问卷在线收集数据。通过探索性和验证性因素分析来验证量表的结构效度，标准效度采用皮尔逊相关性分析，信度采用克朗巴哈系数进行检验。
对29个量表项目进行因素分析和探索性因素分析后，筛选出12个项目和3个因素。这3个因素分别是病原体阻断、传播阻断和免疫力增强。验证性因素分析验证了模型的拟合优度，并验证了量表的收敛效度和区分效度。该量表与呼吸道感染预防实践量表的相关系数为0.69，从而证实了该量表的标准效度。最终量表的信度（克朗巴哈系数）为0.86。
该量表反映了韩国成年人群的社会特征，易于向普通公众发放且简明扼要，有助于后续感染预防研究。
