Views of aging are broadly defined as beliefs a person has about old age, the aging process, or their own aging (Wurm et al., 2017). This project explored how changes in health influences changes in views of aging across older adulthood. Additionally, in two studies, this project explored different categories of activities as potential mediators explaining the association between changes in health and views of aging. In Study 1, a nationally-representative sample of adults over the age of 50 (n =1923) was used to assess how changes in physical, mental, and cognitive health were associated with changes in views of aging, mediated by different categories of activities. In Study 2, a smaller longitudinal sample of older adults over age 65 (n =150) was also used to explore the domainspecific nature of these constructs. Domain-specificity was assessed by analyzing how changes in three types of health (physical, mental, cognitive) were associated with changes in views of aging within those same domains (physical health, mental health, and cognitive health) and if activities associated with those domains were the strongest mediators. In Study 1, results found that changes in all types of health were associated with changes in views of aging. More specifically, experiencing declines in all types of health was associated with progressively more negative views of aging. Additionally, aligned with hypotheses, changes in activity engagement was a small but significant mediator for these associations. In contrast, Study 2 only found an association between changes in physical and mental health and views of aging within those domains. There were limited mediation effects found in Study 2 and support was not found for the domain-specific expectations of the mediation strengths. In conclusion, this study found support for a linkage between changes in physical, mental, and cognitive health and views of aging. Some support was also found in the larger, nationally-representative sample that changes in activity engagement were a partial mediating mechanism between changes in health and views of aging. There was mixed evidence as to the strength of the mediation and the domain-specificity. These findings suggest changes in activity engagement may be one important mechanism fueling the association between changes in health and views of aging, but future research is needed to address limitations of this project and to better understand the longitudinal within-person trajectory of views of aging. }, keywords = {Aging, health}, url = {https://repository.lib.ncsu.edu/bitstream/handle/1840.20/38303/etd.pdf?sequence=1}, author = {Allura Lothary} }
