Purpose: The purpose of this study was to investigate the validity and reliability of the Korean Version of the Grit (Grit-K) scale for nursing students in Korea. Methods: The participants in the study were 277 nursing students. Their grit was verified by using self-reports and the results of a questionnaire. Grit was translated into Korean and its content validity was verified by five experts. The validity of the instrument was verified through item analysis, exploratory factor analysis, and confirmatory factor analysis. Reliability verification was analyzed by using internal consistency reliability. Results: Two factors were identified through exploratory factor analysis and six items of the original instrument were found to be valid. In the confirmatory factor analysis, the validity of the instrument was verified as the model. The internal consistency reliability was also acceptable and Grit was found to be an applicable instrument. Conclusion: This study shows that the Korean Version of the Grit Questionnaire is a valid and reliable instrument to assess nursing students in Korea.

Objectives: A descriptive survey was used in this study to identify the relationship between nursing students' grit, critical thinking disposition, and clinical competence and to examine factors that influence clinical competence. Methods: Data were collected from 241 nursing students and analyzed using t-test, ANOVA, Scheffé test, Pearson correlation, and stepwise multiple regression analysis with the SPSS/WIN 24.0 PC program. Results: Clinical competence was found to have significant pure correlations with critical thinking disposition (r=.49, p<.001), and grit (r=.31, p<.001). The most influential factors influencing nursing students' clinical competence were critical thinking disposition (β=.35, p<.001), and grit (β=.28, p<.001), and these factors explained 33% of the variance in clinical competence. Conclusions: The findings indicate the need to develop and apply strategies and educational programs to enhance individual nurse's critical thinking disposition and grit. Furthermore, exploration is needed on ways to enhance clinical competence.

Purpose: The purpose of this study was to investigate the mediating effect of optimism on the relationship between grit and learning flow in nursing college students. Methods: Structured self-reported questionnaires were used to measure grit, optimism and learning flow. The study was conducted on 200 nursing students in P, U and J cities between September 1 and September 20, 2020. The data were analyzed using a t-test, one-way ANOVA, Pearson's correlation coefficients and hierarchical multiple linear regression with SPSS/WIN 23.0. Results: Significant relationships were found between learning flow and grit (r=.60, p<.001), between learning flow and optimism (r=.42, p<.001), and between grit and optimism (r=.42, p<.001). Additionally, optimism had a partial mediating effect on the relationship between grit and learning flow (Z=3.11, p<.001). Conclusion: These results indicate that interventions to increase the level of grit along with optimism is necessary in order to increase the level of nursing college students' learning flow.

Objective: The present study examined long-term effects of media use during early childhood on grit in middle childhood, focusing on the mediating role of attention problems. Methods: For statistical analysis, the 6th, 7th, and 11th data sets from the Panel Study on Korean Children were used. A total of 1,352 cases were finally selected. Descriptive statistics analysis, correlation analysis, path analysis, and bootstrapping were conducted. Results: The results showed that the use of media for educational purposes in early childhood did not have a significant effect on attention problems and grit. However, when the media use time for play in early childhood was longer, levels of attention problems in early childhood were higher and levels of grit in middle childhood were lower. The mediating effect of attention problems on the relationship between media use time for play of young children and grit of middle childhood was significant. Conclusion/Implications: Findings of the present study suggest that the use of media for play during early childhood needs to be carefully monitored because it can have a negative effect on attention and grit development.

Purpose: This is a study to confirm the mediating effect of positive psychological capital in the relationship between the self-determination and grit of nursing students. Methods: The subjects of the study were 122 university nursing department students in their junior and senior years. The data were collected from December 1 to 23, 2022. The collected data were analyzed by descriptive statistics, an independent t-test, Mann-Whitney U-test, Pearson's correlation, and a hierarchical multiple regression analysis using IBM SPSS statistics version 26.0. Results: A statistically significant correlation was observed between self-determination, positive psychological capital and grit (p<.001). The positive psychological capital had full mediation effects on the relationship between self-determination and grit. In other words, the higher levels of positive psychological capital were associated with better levels of grit among nursing students. Conclusion: The study showed that positive psychological capital and self-determination have important effects on grit. To enhance the grit of nursing students, it is essential to implement educational programs aimed at improving self-determination and positive psychological capital.
