Purpose: This study aimed to construct and test a hypothetical model to explain predictive factors affecting nursing students' satisfaction and self-confidence in simulation-based education based on the National League for Nursing Jeffries Simulation Theory. Methods: A cross-sectional study was conducted on 305 fourth-year nursing students with experience in simulation-based education enrolled at universities in Gangwon-do, Gyeongsangbuk-do, and Gyeonggi-do. Data were analyzed using SPSS 25.0 and AMOS 25.0. Results: The hypothetical model showed good fit with the empirical data: χ2/df 2.17, RMSEA=.01, RMR=.01, GFI=.95, AGFI=.91, NFI=.94, TLI=.95, CFI=.97, and PNFI=.68. Simulation design characteristics, teaching efficiency, and flow were found to affect satisfaction and self-confidence directly. A bootstrap test indicated that teaching efficiency and flow mediated the relationship between simulation design characteristics and satisfaction and self-confidence. Conclusion: Simulation educators should apply best practice that enhance teaching efficiency and flow through well-organized simulation designs, nursing students can attain satisfaction and self-confidence through simulation-based education.

Purpose: This study was aimed to analyze the research trends by investigating the nursing theories used in research articles in Journal of Korean Academy of Nursing for the last 10 years. Methods: Among the research articles published in the Journal of Korean Academy of Nursing for the past 10 years from 2010 to 2019, the research trends was analyzed by investigating the nursing theories used in the studies. Results: As the results of a survey of 847 papers published in the Journal of Korean Academy of Nursing from 2010 to 2019, 139 studies applied to the theory were extracted. As for the theory, one Grand Theory, Roy’s adaptation model, and 6 Middle Range Theories including Kolcaba’s comfort theory, Pender's health promotion model, King's goal attainment theory, Watson's human caring theory, Reed's self-transcendence theory, Mishel's uncertainty in illness theory. Conclusion: In nursing, more use of nursing theories in research is necessary in the future, not only in quantitative research methods but also in qualitative research.
