Abstract: ObjectivesMarital support is central to couples’ relationships, yet support’s health implications can vary widely. Guided by attribution bias and aging theories, the current study examined whether age and marital satisfaction moderate the links of perceived and received spousal support to aging-related biomarkers.MethodsCouples (N = 93, ages 22–77) rated marital satisfaction, overall perceived spousal support, and the quality of support received from their spouse in a lab-based discussion. Blood samples collected at baseline, immediately post-discussion, 3 hr post-discussion, and end-of-visit were assayed for proinflammatory cytokines tumor necrosis factor (TNF)-α and interleukin (IL)-6, as well as insulin-like growth factor (IGF)-1.ResultsConsistent with predictions, less satisfied older couples who received lower-quality spousal support during their discussion had greater increases in TNF-α than those who received higher-quality support; highly satisfied couples of all ages and less satisfied younger couples did not show these inflammatory changes. Highly satisfied older couples with greater perceived spousal support had lower TNF-α across the day and higher IGF-1.DiscussionMarital satisfaction and age may shape spousal support’s significance for healthy aging. Rose-colored lenses worn only in the most satisfying marriages may protect couples from the possible health risks of low-quality received support and enhance potential benefits of perceived support. For better or worse, these health implications may grow with older age.
