Validation of the Disaster Preparedness Evaluation Tool for Nurses-The Korean Version

(1) Background: The purpose of this study was to validate a Korean version of the disaster preparedness evaluation tool (DPET-K) for nurses and to verify its validity and reliability for use in community healthcare centers and hospitals in South Korea; (2) Methods: In total, 497 nurses (248 for exploratory factor analysis and 249 for confirmatory factor analysis) at public health centers, public health sub-centers, public health clinics, and general hospitals in Seoul and Gyeonggi, Chungcheong, and Gangwon Provinces participated in this study. The tool went through translation and back-translation, content validity verification, a pilot survey, and validity and reliability testing; (3) Results: The DPET-K had 28 items with five factors (disaster education and training, disaster knowledge and information, bioterrorism and emergency response, disaster response, and disaster evaluation). The Cronbach's α values for internal consistency were 0.766-0.953 for the five subscales of the DPET-K. A structural equation model was built through confirmatory factor analysis for goodness of fit (χ²/df = 2.193, SRMR = 0.060, RMSEA = 0.069, GFI = 0.831, CFI = 0.927, NFI = 0.875); (4) Conclusions: The DPET-K was confirmed to be a useful tool for assessing the disaster preparedness of nurses in Korea.
