This article reports on a study that incorporates two dimensions of complexity in intergenerational relations. First, the article focuses on ambivalence: the simultaneous existence of positive and negative sentiments in the older parent-adult child relationship. Second, the research described here applies a within-family design

These findings indicate that within-family differences in support to children continue across the life course. Such variations within the family underscore the importance of using designs that provide information on relationships between parents and each of their children, rather than focusing on single parent-child dyads.

Despite a powerful social norm that parents should treat offspring equally, beginning in early childhood and continuing through adulthood, parents often differentiate among their children in such domains as closeness, support, and control. We review research on how parent–child relationships differ within families, focusing on issues of parental favoritism and differential treatment of children. We begin by examining within-family differences in childhood and adolescence and then explore differentiation by older parents among adult children. Overall, we find considerable similarities across the life course in the prevalence, predictors, and consequences of parents' differentiation among their offspring.

Ties to parents or grown children may be the most important social relationships in an adult’s life. Research examining intergenerational relationships has focused on three broader topics: (a) the strength of emotional bonds, (b) exchanges of social support, and (c) the effects of the relationship on individual well-being. This review considers some of the major theoretical developments in the field including solidarity and intergenerational ambivalence theory as well as the newly developed multidimensional model of support. We also consider weaknesses in the research and theories to date and provide suggestions for future research.
