Development of a Health Problem Prevention and Control Strategies Scale for Medical Rescuers Fighting Epidemics

This study aimed to develop and validate a new scale to measure health problem prevention and control strategies employed by medical rescuers fighting epidemics. In Study I, a qualitative study, focus group discussion, and expert panel review were conducted to generate items that capture components of prevention and control strategies. In Study II, exploratory factor analysis was used to examine the scale’s structure. In Study III, the scale’s validity and reliability were assessed via confirmatory factor analysis, average variance extracted, composite reliability, and Cronbach’s α. Data analysis was performed using Nvivo 12.0, SPSS 25.0, and Amos 23.0. The final scale was divided into three subscales (comprising 5 factors and 18 items on the Before Medical Rescue subscale, 6 factors and 28 items on the During Medical Rescue subscale, and 4 factors and 14 items on the After Medical Rescue subscale). The scale has excellent validity and reliability and can be used to measure the health problem prevention and control strategies of medical rescuers fighting epidemics.
