Objectives Emerging evidence suggests that financial and health literacy deteriorates in advanced age. By contrast, well-being promotes health in aging. This study tested the hypothesis that well-being is associated with slower aging-related literacy decline. Methods Participants were 1,099 community-based older adults without dementia at baseline. Financial and health literacy was assessed at baseline and annually thereafter via a 32-item measure. Well-being was assessed at baseline via the 18-item version of Ryff's Scales of Psychological Well-Being. Results During up to 12 years of annual follow-up, literacy declined about 1 percentage point per year on average (β = −0.91, standard error [ SE ] = 0.08, p <.001); however, there was considerable variation in change in literacy between participants (random slopes variance = 1.24, SE = 0.15, p <.001). In a linear mixed-effects model adjusted for age, sex, and education, higher well-being was associated with higher starting level of literacy (β = 2.31, SE = 0.67, p =.001) and, critically, slower literacy decline (β = 0.29, SE = 0.11, p =.01). The association of higher well-being with slower literacy decline persisted in models that additionally adjusted for income, medical conditions, depressive symptoms, and a robust measure of global cognition. Discussion This study suggests that well-being helps stave off aging-related literacy decline. [ABSTRACT FROM AUTHOR]
