Purpose: The purpose of this study is to identifying factors influencing organizational commitment of nurses in Korean Red Cross Blood Center (KRCBC). Methods: A cross sectional survey was conducted for 224 nurses who worked for more than three months in KRCBC. Data were collected using a structured questionnaire from August 28 to September 20, 2018. Data were analyzed using independent t-test, Mann-Whitney U test, one-way ANOVA, Pearson''s correlation coefficient, and hierarchical multiple regression analysis with SPSS (ver. 23.0). Results: The mean score of organizational commitment was 3.37±0.52 on a scale of 5 points, the mean of positive psychological capital was 3.51±0.51, communication ability score was 3.60±0.48, and social support score was 3.68±0.57. The factors influencing organizational commitment of nurses in KRCBC were social support (β=.41, p<.001), job satisfaction (β= .27, p<.001), and total length of employment in KRCBC (β=.19, p=.016). The model explained 36.1% of the organizational commitment of the nurses. Conclusion: It is necessary to develop an organizational commitment program for strengthening social support and job satisfaction to improve organizational commitment of nurses in KRCBC.
