After-Hours Service Demands and Dentist Well-Being: Unpacking the Roles of Compassion Satisfaction and Organizational...

Background/Objective: This study examines how after-hours service demands (AHSD) are associated with dentists' overall work experience (OWE) through the mediating role of compassion satisfaction (CS) and the moderating role of perceived organizational support (POS). Grounded in the Job Demands-Resources (JD-R) and Conservation of Resources (COR) theories, the study investigates how job demands, emotional resources, and organizational support jointly relate to dentists' psychological well-being. Methods: Data were collected from 450 dentists across seven major Libyan cities-Tripoli, Benghazi, Misrata, Sabha, Al Bayda, Zawiya, and Derna-using a structured online questionnaire administered between May and August 2025. Results: Partial least squares structural equation modeling (PLS-SEM) results indicated that AHSD were positively associated with both CS and OWE, suggesting that demanding work conditions may, under certain conditions, coincide with more positive professional experiences when perceived as meaningful and supported. CS partially mediated the AHSD-OWE relationship, highlighting its role as a key emotional resource linked to more favorable work experiences. In addition, POS moderated the relationships between AHSD and CS, and between AHSD and OWE, although the effects were relatively modest, indicating that organizational support may provide incremental support in how dentists experience demanding work conditions rather than fundamentally altering these relationships. The moderated mediation analysis further suggested that the indirect association between AHSD and OWE via CS was stronger at higher levels of POS. Conclusions: Overall, the findings refine JD-R and COR perspectives by indicating that job demands, emotional resources, and organizational support are jointly associated with dentists' work-related well-being in a high-demand healthcare context.
