The effects of co-residence on the subjective well-being of older Chinese parents

The purpose of this study was to examine the effects of co-residence on the parental subjective well-being among older Chinese parents. Our analysis included 2968 elderly parents. Parental subjective well-being was stratified into positive well-being (PWB) and negative well-being (NWB). Positive well-being was assessed through questions about life satisfaction, optimism, and happiness and NWB was measured by questions about fear, loneliness, and feelings of uselessness. We found co-residence with adult children resulted in a significant average increase in PWB by 0.17 points relative to those who did not cohabitate. In rural China, co-residence with adult children significantly increased PWB by 0.19 points, and co-residence with a son significantly increased parental PWB by 0.18 points. Negative well-being fell significantly by 0.63 points if co-residence was with an adult daughter. Our findings imply that support from adult children significantly improved parental PWB, especially for the elderly in rural China. Public policies that facilitate the strengthening of cohabitation may help improve the well-being for older Chinese residents. Our study makes two main contributions to the international literature: first, we strengthened the causal inferences regarding the effects of co-residence with adult children on parental well-being through the use of a longitudinal study design; and second, we introduced a difference-in-differences propensity score matching (PSM-DID) approach to address potential selection bias that has previously been ignored in the literature.
