Objective To investigate the status quo and influencing factors of psychological contract violation among ICU nurses in Guangzhou. Methods A total of 176 ICU nurses from 7 Grade III, Class A hospitals in Guangzhou were selected by convenience sampling, and an online survey was conducted by using self-made general information questionnaire and Psychological Contract Violation Scale. Results A total of 176 e-questionnaires were completed and 167 valid e-questionnaires were recovered. The score of Psychological Contract Violation Scale for nurses was (69. 13±11. 75), and the item average score was (3. 29±0. 56). The results of multiple Regression analysis showed that the highest education level, the relationship between doctors and nurses, and whether or not they had participated in the career planning lectures or activities organized by the unit were the influential factors of psychological contract violation (P<0. 01) .

Nursing managers should carry out targeted intervention measures to regulate nurses and train their ability to control their emotions, enhance the level of job embeddedness, enhance their sense of responsibility and loyalty to the unit, create a good organizational climate and reduce their psychological contract violations.
