Abstract: Objective To investigate the status quo of proactive behavior,professional respect,perceived hospital resilience and professional success of intensive care unit（ICU） nurses in Sichuan Province,and to analyze the relationship between the four factors. Methods A multi-stage sampling method was adopted to conduct a questionnaire survey of 348 nurses from 6 grade-A tertiary hospitals in Sichuan Province from November to December 2023 by using the general information questionnaire,proactive behavior scale,professional respect scale,perceived hospital resilience scale,and professional success scale to construct and verify the chain mediating effect between the four variables. Results The perception of hospital willfulness score of ICU nurses was（102.69±15.94）points,the career success score was（88.64±18.11）points,the proactive behavior score was（35.14±4.82）points,and the professional respect score was（92.77±10.21）points. There were statistically significant differences in perception of hospital resilience scores among ICU nurses with different ages,ICU working years and monthly average income（all P<0.05）. There were significant differences in proactive behavior scores among ICU nurses with different working years,marital status and monthly average income（all P<0.05）. There were statistically significant differences in professional respect scores among ICU nurses with different genders and ICU working years（both P<0.05）. There were statistically significant differences in career success scores among ICU nurses with different genders,ICU working years,and willingness to engage in ICU nursing work（all P<0.05）.The total score of nurses' professional success was positively correlated with the total scores of perceived hospital resilience,proactive behavior and professional respect（all P<0.05）. The direct effect of perceived hospital resilience on nurses' sense of career success was significant, and the effect value was 0.172. Proactive behavior and professional respect as a separate mediating effect and the chain mediating effect of the two were 0.401,0.031,and 0.015,respectively. Conclusion The sense of professional success of ICU nurses in 6 grade-A tertiary hospitals in Sichuan Province is at a medium level. The chain mediating effect of ICU nurses' proactive behavior and professional respect between perceived hospital resilience and career success was established. Nursing managers can promote the improvement of ICU nurses' sense of professional success by improving their proactive work behavior and professional respect.
