ABSTRACT

Aim

To investigate how leadership support influences nurses' innovation behaviour through the chain mediation of creativity, role identity and knowledge sharing.

Background

Despite the recognised role of leadership in fostering innovation, the mechanisms linking leadership support to nurses' innovative behaviours remain under explored. Clarifying how creativity, role identity and knowledge sharing mediate this relationship is critical for optimising nursing practices.

Design

This was a quantitative cross-sectional study.

Methods

A cross-sectional survey was conducted in March 2024 to collect data using the Leadership Innovation Support Scale, Creativity Role Identity Scale, Knowledge Sharing Scale and Nurses' Innovative Behavior Scale. Descriptive analysis, correlation analysis and chain-mediated effect analysis were performed using SPSS 26.0.

Results

We found a positive relationship between leadership support and nurses' innovation behaviour; creativity role identity and knowledge sharing played a mediating role in this relationship. Moreover, there was a significant chain mediating effect of creativity role identity and knowledge sharing on the relationship between leader support and nurses' innovation behaviour.

Conclusion

Creativity role identity and knowledge sharing act as a chain-mediated mechanism between leadership support and nurses' innovative behaviours. Therefore, hospital managers should focus on the level of leadership support for innovation among nurses and implement targeted measures focusing on creativity role identity and knowledge sharing to improve nurses' innovation.

Impact

To promote the development of innovation in healthcare institutions, motivating nurses' innovative behaviour has become a key focus. Based on role identity theory and social exchange theory, this study explores the chain mediation effects of innovative role identity and knowledge sharing between leadership support and nurses' innovative behaviour. This suggests that supervisors can enhance support to help nurses better recognise their role in the innovation process, promoting the exchange of experiences and sharing of innovative outcomes, thereby further stimulating the overall innovation ability of the team.
