well-being after retirement. However, not many studies have looked at the longitudinal association between ties with children and well-being among the retirees. Therefore, using four waves (2006, 2008, 2010, and 2012) of the Korean Longitudinal Study of Aging (KLoSA), this study examined how parent-child relationship satisfaction changes over time after retirement and how ties with adult children are associated with the longitudinal change in relationship satisfaction.

... s study were Korean adults aged 45 years or older who retired between 2005 and 2006 before the baseline survey (N = 233). The results showed that parent-child relationship satisfaction decreases over 6 years after retirement, and that receiving support from children and having frequent contact with children measured at Wave 1 have positive associations with the initial level of parent-child relationship satisfaction. Interestingly, the results also showed that income level moderates the relationship between ties with children and parentchild relationship satisfaction. For low-income retirees, those with higher levels of contact and support had higher level of parent-child relationship satisfaction across time. However, for high-income retirees, the level of parent-child relationship satisfaction did not differ by the levels of contact and support. These results show that having strong ties with adult children is important for Korean retirees' parent-child relationship satisfaction soon after retirement, especially for low-income retirees.
