Discovering the Pathways from Urban Forests to the Subjective Well-Being of Citizens in Tehran

Rapid urbanization reduces green space and increases urban stressors, yet the mechanisms linking urban forests to residents’ subjective well-being remain incompletely understood. This study examines how perceived access, perceived quality, visitation frequency, and satisfaction with urban forests relate to citizens’ subjective well-being in Tehran. Using an online survey of 672 residents and structural equation modeling, this study estimates direct and indirect pathways among the constructs. The results show perceived access is the strongest predictor, raising visitation, satisfaction, and well-being, while perceived satisfaction is the most powerful direct driver of subjective well-being. Perceived quality positively affects well-being but with a smaller effect, and visitation frequency alone does not significantly improve well-being, underscoring that positive experiential factors such as satisfaction matter more than visit counts. The model explains 69.8% of variance in subjective well-being. This study refines the current theoretical foundation by integrating access, quality, frequency, and satisfaction within a single conceptual framework in a megacity context and directly comparing the relative strengths of accessibility versus quality as pathways to well-being. In the context of current knowledge it is among the first to test these comparative pathways using a large Tehran sample. Practically, these findings suggest that urban policy should prioritize equitable access and design that fosters satisfying experiences, not just increasing visit counts. Future research should use longitudinal or experimental designs, incorporate objective measures, compare multiple cities and types of green spaces, and explore moderators such as perceived safety, motivations for visiting, and place attachment to refine causal understanding and policy guidance.
