Examining the Double-Edged Nature of PSM on Burnout: The Mediating Role of Challenge Stress and Hindrance Stress

Extant research has demonstrated that public service motivation (PSM) might have a dark side on public employees. However, empirical research on this assumption remains unclear. Based on Job Demands-Resources Model, this study explores the psychological mechanism of PSM on burnout and examines the relationship from both positive and negative aspects by classifying work stress into challenge stress and hindrance stress. A study with 255 street-level public employees shows that PSM has significant negative effects on burnout. Specifically, perceived hindrance stress mediates a negative relationship between PSM and burnout, and perceived challenge stress mediates a positive relationship between PSM and burnout. This study not only contributes to the development of theories on the doubled-edged nature and psychological mechanism of PSM in relation to burnout but also provides management enlightenment for improving employees’ well-being and mitigating burnout.
