Abstract
The interaction between two critical resources, emotional intelligence (EI) and perceived organizational support (POS), is studied to understand how they come together to associate resilience and well-being among healthcare professionals. Based on the Conservation of Resources (COR) theory and the Job Demands–Resources (JD-R) model, we explore whether these resources are synergistic or whether there is a substitutive relationship when combined. Data were collected from 304 healthcare professionals in Saudi Arabia, both local and foreign. Using structural equation modeling, we examined a moderated mediation model in which resilience was examined as a mediator of the associations of EI and POS with well-being, and their interaction was included as a correlate of both resilience and well-being. EI and POS both individually showed positive association with resilience and well-being. However, in interaction, they significantly negatively associated with both resilience and well-being, suggesting a substitution effect—i.e., high levels of one resource are linked to a lower marginal value of the other. This suggests a nonlinear dynamic to resource accumulation among pressured healthcare workers. This study advances COR and JD-R theories by uncovering a substitution effect between emotional intelligence and organizational support, offering fresh insights into resource dynamics among healthcare professionals.
