Validity and Reliability of the Korean Version of the Fear of COVID-19 Scale

Background: The present study aimed to translate the Fear of COVID-19 Scale (FCV-19S) into the Korean language and test the validity and reliability of the translated Korean version. Methods: An online questionnaire survey was conducted with 300 adults (aged ≥19 years) living in South Korea. The data collection period was 1 June to 15 October 2020. The Korean version of the FCV-19S (KFCV-19S) was tested in terms of content validity, construct validity, criterion validity, item response theory, and reliability. Results: When the content and construct validity of the FCV-19S was tested, the results showed that all items could be retained in the Korean version. When the criterion validity was tested based on correlation analysis between the KFCV-19S and the State-Trait Anxiety Inventory, the results showed a positive correlation (r = 0.53, p < 0.001). Item suitability test results showed that all items were within the reference value of 0.5–1.5. Internal consistency reliability test results showed a Cronbach’s alpha of 0.81. Conclusion: The applicability of the KFCV-19S for identifying the level of fear Korean people experience regarding COVID-19 was verified. This tool is recommended for use in future assessments of Korean populations regarding levels of fear and anxiety regarding COVID-19
