Mediating Role of Job Satisfaction in the Relationship Between Leisure-Time Physical Activity and Emotional State of Healthcare Workers: A Cross-Sectional Survey

: Background: Work-related stress among healthcare employees can lead to burnout, worsened mood, and job dissatisfaction. Although physical activity is known to enhance mood and mental health, its impact on job satisfaction and emotional well-being in healthcare workers is underresearched. This study aimed to explore the associations between leisure-time physical activity (LTPA), job satisfaction, and emotional state and to investigate the mediating role of job satisfaction in the effect of LTPA on the emotional state of healthcare workers. Methods: A self-administered questionnaire, including items on LTPA, job satisfaction, and the emotional state, was distributed to 98 healthcare workers affiliated with the Bari Polyclinic Hospital (Mean age = 46.3; SD = 15.4 years). Composite measures of global job satisfaction and emotional state were extracted by Factor Analysis using the principal components method. The relationship between LTPA, job satisfaction, and the emotional state was investigated through General Linear Model (GLM) mediation models. Results: There was no significant direct effect of LTPA on negative emotional states (β = −0.08, p = 0.37). However, job satisfaction significantly mediated this relationship (β = −0.09, p = 0.04), indicating that engaging in LTPA increased job satisfaction, which in turn reduced negative emotional states. Similarly, LTPA did not have a significant direct effect on positive emotional states (β = 0.06, p = 0.48), but it indirectly resulted in increased positive emotional states through its positive impact on job satisfaction (β = 0.12, p = 0.03). Conclusions: The findings indicate that LTPA indirectly influences both negative and positive emotional states through job satisfaction. Engaging in LTPA enhances job satisfaction, which subsequently leads to reductions in negative emotional states and increases in positive emotional states among healthcare workers. These results underscore the importance of promoting physical activity as a strategy to improve job satisfaction (JS) and the emotional wellbeing of healthcare workers.
