The impact of psychological capital on nurses’ job performance: a chain mediation analysis of problem-focused coping and job engagement

Abstract Background Previous studies have explored the relationships of psychological capital with employees’ job performance in the health sector. However, the possible indirect pathways, including a serial mediation of problem-focus coping and job engagement, have not been extensively examined. This article explores how psychological capital influences nurses’ coping strategies focused on problem-solving, their level of engagement with their jobs, and how this, in turn, affects their job performance. Methods The study involved 575 nurses from Cameroon’s public health sector. It investigated how psychological capital, an intrinsic resource, triggers nurses’ problem-focus coping liaison with job engagement to impact job performance. Analysis was conducted to assess the relationships among psychological capital, problem-focus coping, job engagement, and job performance with the use of SmartPLS 4.0 and PROCESS 4.2. Results Findings revealed a significant effect of psychological capital on problem-focus coping, job engagement and job performance. Moreover, notable relationships were identified between psychological capital, problem-focus coping, job engagement, and performance, highlighting a chain mediation effect. Conclusion The research advocates for hospital managers to employ strategies fostering employees’ psychological capital to better cope with organizational stressors to promote job engagement and enhance job performance. The study contributes fresh insights into healthcare organizational dynamics and human resource management, providing a foundation for future advancements in this field.
