The mediation role of positive psychological capital in the relationship between perceived organizational support and employee performance: a research on port administration employees

Purpose – In this study, a conceptual model was developed and analyzed to test the mediating role of positive psychological capital (PPC) in the impact of organizational support perceived by employees who continue their professional lives in the port sector, which is an important sub-branch of the maritime sector, on employee performance (EP). Design/methodology/approach – The data for the analysis of the model in question were collected through a survey method from employees in the work site and units of 14 port enterprises in the Eastern Mediterranean region of Turkiye. A total of 406 usable data were analyzed with the SmartPLS 4 analysis program. € Findings – The analysis did not confirm the significant positive effect of perceived organizational support (POS) on EP. On the other hand, the analysis found that POS had a significant positive impact on PPC. Likewise, the significant positive effect of PPC on EP was confirmed. The analysis also concluded that PPC was the full mediator variable in the impact of POS on EP. Practical implications – This study helps managers find out how they can improve employees’ EP with qualified POS and PPC. Originality/value – The current study reveals the role of PPC in the mechanism underlying the controversial relationship between POS and EP and, thus, contributes significantly to both literature and practice.
