Objective To understand the status quo of head nurse′s decision-making style and analyze the influencing factors, and to provide references for selection,evaluation and training of head nurses. Methods Convenience sampling method was used to select 389 head nurses in Anhui Province, and the general information questionnaire, the Emotional Intelligence Scale and the General Decision Style Scale were used to survey the participants. Results The decision-making styles used by head nurses in descending order were rational （4.09±0.76）, dependent （3.61±0.67）, intuitive-impulsive （2.89±0.55） and evasive （2.45±0.88） styles. Multivariate regression analysis showed that the use of emotions, degree （bachelor degree and above）, and the location （city） of household registration were the influencing factors of the rational style; the levels of education （college and below） and the location （city） of the household registration were the influencing factors of the evasive style; the use of emotion and position （deputy head nurse） were the influencing factors of dependent style, and self-emotion monitoring was the influencing factor of intuitive-impulsive style （P＜0.05，P＜0.01）. Conclusion The head nurse′s decision-making style is worthy of attention, especially the head nurse with lower levels of education and lower position.Targeted training should be rolled out in an effort to improve head nurses′ ratio-nal decision-making ability and enrich their decision styles.
