The Role of Volunteer Participation and Person-Organization Fit in the Relationship between Motives and Psychological Well-Being

(1) Background: Studies have been limited in explaining how volunteering acts as underlying mechanisms that associate the antecedents and outcomes of volunteering. This study aims to investigate whether volunteer participation mediates the relationship between motives (self-oriented and other-oriented) and psychological well-being, and further whether person-organizational (PO)-fit moderates the relationship between motives and volunteer participation. (2) Methods: Data were collected from full-time employees in organizations in South Korea using a self-administered instrument. To test the hypotheses, hierarchical regression analyses and path analyses were conducted. (3) Results: Volunteer participation showed a significant mediating effect only for the relationship between other-oriented motives and psychological well-being. PO fit showed a significant moderating role, and further analysis revealed that the mediated moderation of PO-fit was significant. (4) Conclusions: Results suggest that employees with other-oriented motives and PO fit were more likely to participate in volunteer activities, which then increased one's psychological well-being. Findings provide insights for HR practitioners regarding employee volunteering programs.
