Objective To explore the status and influencing factors of self-consciousness of nursing under-graduates. Methods A total of 1 411 nursing students were investigated with the Self-consciousness Scale and the Feed-back-Seeking Behavior Scale. The SPSS 26.0 was used for data analysis. The independent t-test or ANOVA was used to compare the scores of self-consciousness among different characteristics. Pearson correlation analysis was used for the correlation among variables. Multiple linear regression was used to analyze the factors influencing self-consciousness of nursing undergraduates. Results The score of self-consciousness of nursing undergraduates was （45.49±8.41）,and there was a positive correlation between self-consciousness and feedback-seeking behavior（r=0.521,P<0.001）. The influencing factors of self-consciousness were the experience of student leader,choosing nursing reason,career choice support from family,feedback-seeking behavior by teacher’s observation,feedback-seeking behavior by classmate’s observation and feedback-seeking behavior by classmate’s inquiry（P<0.001）,which could explain 30.2% of the variance of self-consciousness. Conclusion The self-consciousness of nursing under-graduates is below the middle level. The self-consciousness of nursing undergraduates is affected by the experience of student leaders,whether they choose their major voluntarily,career choice support from family,and different type of feed-back-seeking behavior. Therefore,nursing educators should develop the nursing education measures according to these factors to improve the self-consciousness of nursing undergraduates.
