Abstract

Objective: To explore associations between the 5-factor model (FFM; neuroticism, extraversion, openness/intellect, agreeableness, and conscientiousness), personality traits, and measures of whole-brain integrity in a large sample of older people, and to test whether these associations are mediated by health-related behaviors. Method: Participants from the Lothian Birth Cohort 1936 completed the International Personality Item Pool measure, a 5-factor public-domain personality measure (http://ipip.ori.org), and underwent a structural magnetic resonance brain scan at the mean age of 73 years, yielding 3 measures of whole brain integrity: average white matter fractional anisotropy (FA), brain-tissue loss, and white matter hyperintensities (N = 529 to 565). Correlational and mediation analyses were used to test the potential mediating effects of health-related behaviors on the associations between personality and integrity. Results: Lower conscientiousness was consistently associated with brain-tissue loss (β = -0.11, p
