Key result
High neuroticism was associated with a 33% increased risk of death, while high extraversion was associated with a 21% decreased risk of death in older adults over >6 years.
Why the study?
Do personality traits of neuroticism and extraversion affect the risk of death in older persons?

No
Do personality traits of neuroticism and extraversion affect the risk of death in older persons?
Effect estimate: 33% increase in risk (neuroticism); 21% decrease in risk (extraversion)
Higher extraversion and lower neuroticism are associated with reduced mortality risk in older adults, partially mediated by cognitive, social, and physical activity patterns.
No takes yet. Share an insight, caveat, or question.
Personality traits may refine mortality risk stratification in older adults; hypothesis-generating and requires prospective confirmation.
Wilson et al. (2005) reported a cohort. High neuroticism and high extraversion vs. Low neuroticism and low extraversion was evaluated on Risk of death (33% increase in risk (neuroticism); 21% decrease in risk (extraversion)). High neuroticism was associated with a 33% increased risk of death, while high extraversion was associated with a 21% decreased risk of death in older adults over >6 years.
