Abstract: Objective: To understand the current status of organizational silence among oncology nurses and to analyze its influencing factors, in order to provide references for reducing the level of organizational silence among oncology nurses. Methods: From February to March 2025, using a convenience sampling method, 310 oncology nurses from 18 tertiary hospitals in Foshan were selected as the research subjects. Questionnaires used in this study were the general information questionnaire, the Nurse Organizational Silence Evaluation Questionnaire, and the Nurses' Affective Domain Ability Scale. The multiple linear regression analysis was employed to explore the influencing factors of nurses' organizational silence. Results: The score of organizational silence of nurses in oncology departments was 58.26±8.68. Affective domain ability, age, professional title and working years were the influencing factors of organizational silence among nurses in oncology departments (all P<0.05). Conclusion: The level of organizational silence among oncology nurses is moderate. Managers may enhance the individual affective domain capabilities of nurses and create an open organizational environment. They should also prioritize training younger nurses with lower ranks and shorter working years to encourage them to express their opinions freely, thereby reducing the organizational silence level among oncology nurses.
