Effects of Positive Psychological Capital on Nursing Performance among Clinical Nurses: Mediating Role of Work Engagement
Purpose: This study examined whether work engagement mediates the relationship between positive psy chological capital and nursing performance among clinical nurses. Methods: A cross-sectional survey was conducted from July 1~31, 2025, among 177 clinical nurses from one tertiary and two general hospitals in South Korea. Participants completed self-report questionnaires that measured positive psychological capital, work engagement, and nursing performance. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, multiple regression, and a simple mediation model with the PROCESS macro and a 95% bias-corrected bootstrap confidence interval. Results: Positive psychological capital and work engagement were positively correlated with nursing performance. In the multiple regression model, both positive psychological capital (β=.48, p<.001) and work engagement (β=.17, p=.035) significantly predicted nursing performance, explaining 43% of the variance. Work engagement partially mediated the relationship between positive psychological capital and nursing performance (indirect effect=0.08, boot SE=.04), with a 95% bootstrap confidence interval that did not include zero (95% CI=[.01, .16]). Conclusion: The findings suggest that strategies to enhance nursing performance in clinical settings should focus on promoting positive psychological capital and work engagement through organizational-level and individual-level interventions.
