The Korean version of the Virtual Patient Learning System Evaluation Tool: Assessment of reliability and validity. Nurse education today BACKGROUND:Due to the recent spread of coronavirus disease 2019, Korean nursing colleges are increasingly using virtual patient simulation to make up for a lack of available clinical practice in medical institutions. Therefore, an instrument is required to evaluate the effects of the virtual patient learning system in South Korea. OBJECTIVE:To assess the validity and reliability of the Korean version of the Virtual Patient Learning System Evaluation Tool (K-VPLSET). DESIGN:This is a methodological study. SETTINGS:This study was conducted via an online survey for Korean nursing students. PARTICIPANTS:The present study included 373 participants who were 3rd and 4th year Korean nursing students. METHODS:After translating the English version of VPLSET into Korean, a pilot test with a cognitive interview was undertaken to ensure that the meaning of original instrument and appropriateness for Korean nursing students had been retained. The content validity of the K-VPLSET was examined by a panel of six experts. Convenience sampling was used to recruit 3rd and 4th year Korean nursing students, among whom 170 were recruited for exploratory factor analysis (EFA) and 203 for confirmatory factor analysis (CFA). SPSS version 26.0 was used for EFA, whereas AMOS version 22.0 was used for CFA. RESULTS:From the 32 initial items, the final version of the K-VPLSET ultimately included 20 items, with a Cronbach's α of 0.89. EFA identified four factors ("Nursing Knowledge Improvement," "Clinical Competency Development," "Confidence in Nursing Performance," and "Nursing Care Plan Application") that explained 56.9% of the total variance. CFA confirmed the validity of the instrument. CONCLUSIONS:Our findings confirmed that the K-VPLSET is a valid and reliable instrument for assessing the effects of the virtual patient learning system, through which the quality of e-learning for Korea nursing students can be determined. 10.1016/j.nedt.2021.105093
