Abstract
OBJECTIVE: This study examined the relationships between hope, resilience, and grit with job burnout and psychological well-being, focusing on both direct effects and the mediating role of grit. Given the economic and organizational challenges in Iran, where employees frequently experience occupational stress, understanding these psychological resources is particularly important. METHOD: Participants were 300 employees from the Iran Oil Pipelines and Telecommunications Company in Lorestan, Iran. Five standardized questionnaires were administered, and data were analyzed using structural equation modeling (SEM) with SPSS 26 and AMOS 22. RESULTS: The sample included 295 males and 5 females, with 66 single and 234 married individuals (Mean age = 40.98, SD = 10.28). SEM results showed that hope, resilience, and grit had significant direct effects on psychological well-being and burnout (β = -0.35-0.50, all p < .05). Grit also significantly mediated the relationships between hope and resilience with burnout and well-being. CONCLUSION: Hope, resilience, and grit are strong predictors of employees' psychological well-being and burnout. In Iranian organizational contexts, strengthening these psychological resources through targeted interventions may help reduce occupational stress and enhance mental health.
