Objective To understand the current situation and influencing factors of the three-dimensional character strengths of graduate nursing students, so as to provide reference for taking measures to improve their character.Methods A total of 270 nursing graduate students were selected by convenience sampling method and surveyed by using the Three-Dimensional Inventory of Character Strengths.Results The character strengths score of nursing graduate students was (3.58±0.47) points, affinity was (4.15±0.50), curiosity was (3.27±0.62), and self-control was (3.33±0.64), which were significantly higher than those of the general nursing group (all P＜0.05).Education, work experience, and gender were the influencing factors of the three-dimensional character strengths of nursing graduate students (all P＜0.05).Conclusion The three-dimensional character strengths of nursing graduate students is generally at a high level, but the intellectual curiosity and self-control need to be further improved.Managers should pay attention to the cultivation of the three-dimensional character advantages of nursing graduate students.
