Effect of Life Events, Social Supports, and Personality on Mental Status in Later Life.

The goal of this study was to explore the influences of proximal and distal life events on mental status in later life. Additionally, life events were categorized into positive and negative experiences. Data from 208 older adults over 80 years of age from the Georgia Centenarian Study were included in this study. Results from a series of blockwise regression analyses indicated that the number of distal negative life events that older adults had experienced was a predictor of older adults' better mental status. Oldest-old adults' age, education, social supports, and social provision were also associated with their cognition. Cumulative negative life events may protect people in cognitive function as implicated by our results.
