[영문]Objectives. Despite the centrality of parent?adult child relations, prior research has found only weak associations with parent well-being. There is a need to give more explicit attention to the relations of parents with multiple children and to the potentially mixed or qqqquot;ambivalentqqqquot; nature of those relations. These patterns may differ for mothers and fathers. Methods. Wave 1 of the National Survey of Families and Households provided detailed information on relations between parents and each of their adult children. The sample included 2,270 persons aged 50+ who had at least one child aged 19+. Results. Measures across multiple adult children uncovered more mixed patterns of qqqquot;collective ambivalenceqqqquot; that included lesser quality and/or contact with at least some children. The presence of less positive relations with any children was consistently, albeit modestly, related to lower parent well-being. Mothers reported higher qqqquot;maximumqqqquot; quality and interaction across children, but mothers and father did not differ in qqqquot;minimumqqqquot; reports. Associations between parent?child relations and well-being were similar for mothers and fathers. Discussion. Analyses that incorporate the relations of parents with their multiple adult children, viewed as part of a family network, yield a more comprehensive and nuanced view of those relations and their implications for well-being.
