Purpose
This study examined the effects of organizational socialization and nursing competence on organizational commitment among clinical nurses. Methods: Data were collected from August 12 to August 31, 2024, from 207 nurses with more than 6 months of clinical experience at five general hospitals in a metropolitan area. Data were analyzed using descriptive statistics, the independent t-test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression in IBM SPSS version 27.0. Results: Organizational commitment was positively correlated with organizational socialization and with scientific, ethical, personal, and aesthetic competence. Multiple regression identified organizational socialization (β=.59, p<.001), aesthetic competence (β=.18, p=.012), ethical competence (β=.15, p=.023), and married status (β=.16, p=.010) as significant factors associated with organizational commitment. These variables explained 57.0% of the variance, and the regression model was significant (F=12.65, p＜.001). Conclusion: Healthcare institutions should strengthen organizational socialization and nursing competence through structured education and institutional support to enhance nurses’ organizational commitment.
