This study was conducted to verify the reliability and validity of the Korean version of Impact of Event Scale\u2014Revised (IES-R), one of the most used tools for assessing trauma. Secondary data of 249 nurses who performed face-to-face nursing tasks during the COVID-19 pandemic, collected through an online survey, were analyzed by conducting a factor analysis of the K-IES-R and testing the internal consistency and concurrent validity with the Perceived Stress Scale (PSS), Generalized Anxiety Disorder Screener (GAD-7), and Dimensions of Anger Reactions-5 (DAR-5). The result of an exploratory factor analysis of the K-IES-R supported a three-factor structure of intrusion, avoidance, and sleep disturbance, with CMIN\/DF = 2.98, RMSEA = 0.09, SRMR = 0.03, CFI = 0.93, and TLI = 0.90. The Cronbach\u2019s alpha of each subscale was 0.88\u20130.94. The total K-IES-R score and each factor\u2019s value showed a significant correlation (moderate or higher) with the PSS, GAD-7, and DAR-5. The K-IES-R was verified as a useful tool for assessing post-traumatic stress symptoms in nurses who directly perform nursing tasks in crises such as COVID-19. This study suggests the tool be used for early assessment of post-traumatic stress symptoms in nurses and providing appropriate interventions.<\/jats:p>","DOI":"10.3390\/ijerph182111311","type":"journal-article","created":{"date-parts":[[2021,10,28]],"date-time":"2021-10-28T23:50:28Z","timestamp":1635465028000},"page":"11311","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Validation of the Korean Version of Impact of Event Scale\u2014Revised (IES-R) in Korean Nurses during the COVID-19 Pandemic"],"prefix":"10.3390","volume":"18","author":[{"given":"Young Suk","family":"Park","sequence":"first","affiliation":[{"name":"Department of Nursing, Korea National Open University, Seoul 03087, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kwang-Hi","family":"Park","sequence":"additional","affiliation":[{"name":"School of Nursing, Gacheon University, Incheon 21936, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2302-2897","authenticated-orcid":false,"given":"Juna","family":"Lee","sequence":"additional","affiliation":[{"name":"Center for Human-Caring Nurse Leaders for the Future by Brain Korea 21 (BK21) Four Project, College of Nursing, Seoul National University, Seoul 03080, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,28]]},"reference":[{"key":"ref_1","unstructured":"(2021, May 19).
