Purpose: The study aimed to assess emotional labor, reality shock, resilience, job performance, and organizational socialization among new nurses. Additionally, it sought to determine the factors influencing organizational socialization in this population. Methods: This descriptive study included 135 new nurses who had been working in hospitals or medical institutions for 3-12 months. Data were collected via an online survey conducted from March 24 to May 13, 2024. The data were analyzed using frequency, percentage, mean, standard deviation, t-test, ANOVA, Pearson’s correlation coefficient, and multiple linear regression. Results: The organizational socialization score was 3.23±0.82; emotional labor, 3.34±0.91; reality shock, 2.99±1.03; resilience, 64.16±23.28; and job performance, 80.41±11.35. Factors significantly affecting organizational socialization were reality shock (β=-.48, p<.001), resilience (β=.18, p=.001), emotional labor (β=-.18, p=.001), and job performance (β=.13, p=.001). The model’s explanatory power was 88.2% (F=92.25, p<.001). Conclusion: To enhance organizational socialization among new nurses, it is essential to develop programs that reduce emotional labor and reality shock. Interventions that improve resilience and job performance can also contribute to more effective organizational socialization.
