Mortality Risk Associated With Personality Facets of the Big Five and Interpersonal Circumplex Across Three Aging Cohorts

Abstract

Findings indicate that specific facets of neuroticism and extraversion carry greater or lesser mortality risk. Broad composite scales averaging across all facets mask important personality risk factors. In contrast, nearly all facets within the conscientiousness domain confer protection against mortality. Finally, the IPC model may capture more nuanced interpersonal risk factors than the facets of Big Five agreeableness or extraversion. Understanding of the role of personality in longevity requires a more precise approach to conceptualization and measurement than broad, composite constructs usually provide.
