Abstract: Objective: To explore the mediating effect of organizational support between character strengths and occupational well-being of nurses. Methods: From September to December 2021, a total of 388 nurses were investigated by using the General Information Questionnaire, Three-Dimensional Inventory of Character Strengths, Perceived Organizational Support Scale and Occupational Well-Being Scale for medical workers. Results: Nurses' character strengths had a positive impact on occupational well-being (r=0.399, P<0.001). The character strengths could affect occupational well-being through the mediating factor of nurses' perceived organizational support, with a mediating effect of 70.96%. Conclusion: Perceived organizational support is a mediating variable between character strengths and occupational well-being of nurses. Nursing managers should strengthen perceived organizational support to improve the level of occupational well-being.

Key words: character strengths; perceived organizational support; occupational well-being; mediation effect
