Perceived social position, active engagement with life, and depressive symptoms among older adults

초록

Rationale: Despite the existing literature on the relationship between perceived social position (PSP) and depressive symptoms, there remain gaps in our understanding, particularly regarding the potential for asymmetric effects of increases and decreases in PSP and the underlying mechanisms involved. Objective: This study aims to examine whether increases and decreases in PSP are differentially associated with depressive symptoms and to explore the potential mediating role of active engagement with life in these associations. Methods: This study utilized data from the Korean Longitudinal Study of Aging (KLoSA), collected between 2008 and 2018, involving a sample of 3506 individuals aged 65 or older. Asymmetric fixed effects (FE) models were employed, which enable the estimation of differential effects for increases and decreases in PSP, while accounting for unobserved individual-level heterogeneity. To assess the mediating role of active engagement in life, Sobel mediation tests were conducted. Results: The asymmetric FE estimates revealed a stronger association between decreases in PSP and increases in depressive symptoms compared to the association between increases in PSP and decreases in depressive symptoms. The Sobel mediation tests indicated that formal social activities had the most substantial mediating effect, explaining 14% and 9% of the total effect mediated for increased and decreased PSP and depressive symptoms, respectively. Leisure/hobby activities explained 10% and 4% of the total effect mediated for increased and decreased PSP and depressive symptoms, respectively. Conclusion: This study provides evidence that increases and decreases in PSP have differential effects on depressive symptoms among older adults in Korea. Policy interventions aimed at improving the psychological well-being of older adults should prioritize efforts to both enhance PSP and minimize declines, as the latter can have a stronger negative impact on depressive symptoms. Active engagement in life may serve as a potential pathway for achieving the desired effects. © 2024 Elsevier Ltd
