Five-factor model personality traits and 24-h urinary cortisol in the Baltimore Longitudinal Study of Aging.

ABSTRACT: Stress is implicated in models of personality and health as a mechanism that explains why traits like conscientiousness and neuroticism are associated with long-term health outcomes. Evidence for an association between personality and cortisol, a biological marker of stress, however, has been inconsistent. This study examined the association between Five-Factor Model personality traits and 24-h urinary cortisol (operationalised as a ratio of urinary free cortisol to creatinine) measured up to 12 times over intervals as long as 30 years in the Baltimore Longitudinal Study of Aging (M_age  = 61.21, SD = 15.46; 49% female). There was a modest association between conscientiousness and lower mean-level cortisol that was attenuated only slightly in the fully-adjusted model. Neuroticism
