Abstract
With the global aging population increasing, promoting psychological well-being (PWB) in later life has become critical. This study employed a cross-sectional design to examine the impact of connectedness to nature (CtN) on PWB among Chinese older adults, focusing on the mediating role of self-perceptions of aging (SPA) and the moderating effect of meaning in life (MIL). Data from 401 participants were analyzed using a moderated mediation model, controlling for demographic variables. The results indicate that CtN is positively associated with PWB, partially through reducing negative SPA. Moreover, MIL strengthens both the direct effect of CtN on PWB and its indirect effect via SPA. These findings underscore the importance of fostering nature connection and meaning in life to enhance well-being in older adults and offer valuable insights for interventions promoting healthy aging.
