Materials and Methods: The study employed a cross-sectional research design involving nurses working at a university hospital. Data were collected between October and December 2024, and 331 nurses were included in the study. Data were gathered using three different scales, in addition to statements measuring demographic factors. SPSS 26 and Amos programs were used for data analysis. Descriptive statistical methods, correlation analysis, and regression analysis using Hayes’ Process Macro Model 4 were performed. Results: Of the study group, 282 (85.2%) were female, 203 (61.3%) were married, and 261 (78.9%) had undergraduate or graduate education. According to the findings of the study, collaboration (β=0.29) and emotional support from coworkers (β=0.51) had a significant positive effect on psychological ownership. In contrast, instrumental support from coworkers showed a weak and negative effect (β=-0.16). The mediating roles of instrumental and emotional support in the effect of collaboration on psychological ownership were found to be low, and positive (β=0.16). When the mediating effects were considered, the total effect of collaboration on psychological ownership increased significantly (β=0.45). Conclusion: The results indicate that collaboration enhances psychological ownership among nurses in the sample. Furthermore, as a mediating variable, emotional support from coworkers plays a significantly more effective role compared to instrumental support.}, number={2}, publisher={Balıkesir Üniversitesi}
