How Social Network Size and Quality Affect End-of-Life Surrogate Preferences

ObjectiveOlder adults typically choose their next-of-kin to serve as surrogate on their behalf should they become decisionally incapacitated at the end of life. However, some older adults do not choose their closest relative, even if they are married or parents. We compared the social networks of these latter persons to their peers who prefer a next-of-kin surrogate, anticipating differences in relationship quality and network size.MethodsWe used multinomial logistic regressions to investigate the quality and size of the social networks of 1,245 persons whose next of kin was a spouse and 723 persons whose next-of-kin was an adult child, and who participated in the 2005 National Social Life, Health and Aging Project.ResultsTwenty percent of those whose next-of-kin was a spouse and 32% of those whose next-of-kin was an adult child either bypassed that person in favor of a different surrogate, or preferred no surrogate at all. Low-quality next-of-kin relationships pushed older adults away from next-of-kin, and a greater number of high-quality relationships outside the immediate family pulled older adults toward a surrogate who was not next-of-kin.DiscussionWe discuss what is distinctive about the social networks of each group, and the implications for end-of-life support.
