The influence of the personality traits of newly graduated nurses on the knowledge, skills and professional self-efficacy in standardized training: a cross-sectional study

New graduate nurses often have certain potential safety hazards for patients due to insufficient knowledge and lack of clinical practice ability. To address these challenges, China has implemented a standardized training strategy. The improvements in the quality of this training involve not only the intervention of teaching methods but also the consideration of personality traits. The application software based on the BFI-2 Chinese scale was utilized to administer personality tests to nursing students; nursing students were invited to scan the QR code and voluntarily fill in a questionnaire, including basic information, personality test results, and a professional self-efficacy test scale; offline paper-based theoretical examination results of nursing students were collected before and after training. The data was then analyzed using SPSS software version 26.0, which involved descriptive analysis, one-way between-groups analysis of variance (ANOVA) and Spearman correlation analysis. Based on the data, there were no observable differences in the theoretical results before and after training across different personality traits. In terms of skill assessment, conscientiousness exhibited the highest score at 78.91 ± 2.98 points, while negative emotionality showed the lowest score at 74.59 ± 2.12 points. These differences between different personality traits are statistically significant (P
