Purpose: This study aimed to examine the differences in the reciprocal causal relationship between cognitive function and depressive symptoms depending on whether older adults lived with others or alone.
Methods: We used panel data retrieved from the sixth (Time 1) and seventh (Time 2) waves of the Korean Longitudinal Study of Aging (KLoSA). The study sample included 2,638 older adults living with others and 628 older adults living alone. We conducted cross-lagged panel analyses (CLPA) to identify the bidirectional causal relationship between cognitive function and depressive symptoms in the groups of older adults living with others and those living alone.
Results: In the group of older adults living with others, cognitive function and depressive symptoms showed significant reciprocal relationships. In the group of older adults living alone, although the CLPA confirmed that higher levels of depressive symptoms at Time 1 influenced lower levels of cognitive function at Time 2, cognitive function at Time 1 was not associated with depressive symptoms at Time 2.
Conclusion: The results suggest that the strategies for preventing cognitive decline and depressive symptoms should be developed according to whether the older adults live alone. Moreover, further studies should identify factors influencing depressive symptoms among older adults living alone, which will ultimately enable the management of depressive symptoms.
