To understand the status quo of nurses' professional mission and explore the influencing factors of nurses' professional mission.

From November to December, 2018, 316 nurses from three tertiary hospitals in Tianjin were selected as the research objects. The occupational mission scale was used to investigate the sense of professional mission, the nursing work environment scale was used for the nursing work environment survey, and the work family conflict scale was used for the work family conflict investigation. Pearson correlation analysis was used to analyze the correlation among nurses' sense of professional mission, nursing work environment and work family conflict; multiple linear regression analysis was used to analyze the influencing factors of nurses' sense of professional mission.

The score of professional mission of nurses was (2.90±0.56) . Average monthly income, nursing work environment and work family conflict were the influencing factors of nurses' professional mission (P<0.05) . The results of hierarchical regression showed that the higher the average monthly income (β=0.252) , the higher the sense of professional mission of nurses (R²=0.064) ; after controlling general data, the two dimensions of nursing work environment: Nurses' participation in hospital affairs (β=0.263) , high-quality nursing service foundation (β=0.368) , and work family conflict (β=-0.145) could explain 43.1% of the total variation of professional mission.

The sense of professional mission of nurses is above the middle level. Nursing managers should start with the influencing factors such as average monthly income, nursing working environment and work family conflict, so as to stimulate or improve nurses' sense of professional mission.
