Abstract

This study examined the joint roles of dispositional optimism and Big-Five personality factors in preserving “Not-Impaired-Not-Demented” status, assessed four times biennially over an eight-year period, among older Black Americans born before 1964. Mediation by biomarkers (e.g., Cystatin C, C-reactive protein, blood sugar, lipids, BMI, blood pressure), assessed twice quadrennially, was also tested to confirm possible facilitation of homeostasis by these traits.
