No evidence for a close relationship between personality traits and circadian cortisol rhythm or a single cortisol stress response.
Personality traits measured with the Eysenck Personality Questionnaire-Revised did not show associations with basal or stimulated concentrations of cortisol in a sample of 81 subjects. Cortisol responses to a single exposure to psychosocial stress as well as circadian salivary-free cortisol patterns did not distinguish between subjects with high or low scores on Extraversion, Neuroticism, or Psychoticism, respectively.
