Prior research has reported that the relationship between quality of social relationships and depression is reciprocal among middle-aged and older adults. However, little is known about a bidirectional relationship over time. To address this research gap, this study aims to investigate (1) a bidirectional relationship between social relationships and depression among middle-aged and older adults, and (2) whether there are significant differences between the age groups. Using 4-year data (2014-2017) from Korea Welfare Panel Study, a nationally representative longitudinal survey, a total of 2,573 Korean participants (1,147 middle-aged adults aged 55-64 and 1,426 the young-old aged 65-74) was selected. Autoregressive cross-lagged modeling was performed. The Center for Epidemiologic Studies Depression scale was used to measure depression. The quality of social relationships was assessed by a composite score of two Likert-scale items (satisfaction with family and friends relationship). The model showed adequate fit indices (RMSEA=.040, CFI=.957). The results revealed that there are significant differences between two age groups in the reciprocal association of social relationships with depression. The negative lagged effect of quality of social relationships on depression over the four years was significant in both groups. However, the negative lagged effect of depression on the quality of social relationships was only significant in the young-old, suggesting that higher levels of depression predicts lower levels of social relationships.
