Abstract: Objective To understand the satisfaction level of professional competence training for standardized training of resident physicians in Tianjin,and to provide reference for improving residential training work in the future. Methods A self-designed questionnaire was used to conduct a satisfaction survey among 329 resident physicians enrolled in Tianjin's 2022 training program using stratified random sampling by grade from February 20 to 28,2023. Principal component analysis was used to calculate the weights of each dimension indicator. Results In the comprehensive evaluation of resident physicians' satisfaction with professional competency,the weights of influencing factors from highest to lowest were training effectiveness（21.26%）,assessment and management （20.80%）,training base conditions（20.50%）,teaching quality（20.41%） and salary benefits（17.03%）. There were statistically significant differences in the satisfaction of resident physicians with different educational backgrounds,training grades,marital and pregnancy status,and types of trainee（all P<0.05）. Conclusion The overall satisfaction with the standardized training for resident physicians in Tianjin is good. The four dimensions of training effectiveness,assessment and management,training base conditions,and teaching quality have a significant impact on the satisfaction of resident physician training.
