Mediating Role of Resilience in the Relationships Between Objective Physical Activity With Depression and Stress Among Nurses in Türkiye

Objective Nurses belong to a professional cohort that frequently experiences depression and stress. The objective of this research was to examine the correlation between objective physical activity (PA) with depression and stress among nurses, with a specific focus on the mediating role of resilience. Methods This study employed the descriptive-correlation method. One-hundred twenty-seven nurses (76 women) working in hospitals in Bitlis province, Türkiye in 2023 were selected using a convenience sampling. To measure PA, depression, stress, and resilience, ActiGraph GT3X-BT accelerometer, Beck Depression Inventory, Perceived Stress Scale, and Connor-Davidson Resilience Scale were utilized, respectively. Data analysis was conducted using Pearson correlation test and structural equation modeling. Results Nurses, particularly women, experienced a moderate level of depression and stress. Moreover, the number of step counts was significantly higher in day vs. night shift. Overall, the nurses in this study, especially women, engaged in PA levels that were significantly below the international guidelines for adults (p<0.001). Additionally, higher intensity levels of PA (i.e., moderate PA [MPA] and vigorous PA [VPA]) were found to be linked with reduced levels of depression (β=-0.528, β=-0.410, respectively) and stress (β=-0.605, β=-0.531, respectively). Lastly, resilience was identified as a significant mediator in the correlation between MPA and VPA with depression and stress (p<0.05). Conclusion These findings hold great significance as they demonstrate the positive impact of both resilience and PA on the mental well-being of nurses. It is advisable for healthcare authorities to formulate policies and strategies aimed at enhancing the overall stability and performance of the healthcare sector.
