Understanding the Interplay of Religion, Social Relationships, and Depressive Symptoms in Later Life: An Analysis of Dynamics in Individual and Dyadic Contexts.

This study examined how religious participation at the individual level and the dyadic religious similarity at the couple level influenced depressive symptoms via social relationships among older Korean couples aged 65 and above. The sample included 1,191 couples from the seventh assessment of the Korean Longitudinal Study of Ageing. The findings indicated that older adults who participated in religious activities more frequently showed lower levels of depressive symptoms through increased social interactions and marital satisfaction. Additionally, older couples with similar religious backgrounds showed higher levels of marital satisfaction than those without similar religious backgrounds, subsequently leading to lower levels of depressive symptoms. Overall, the associations between religion and depressive symptoms were similar for both genders. The findings provided insights into potential mechanisms leading to later-life depressive symptoms at both the individual and couple levels in terms of religion and social relationships and informed practical implications for older couples' marital relationships.
