The relation between dominance, anger, and hormones in normally aging men: results from the Massachusetts Male Aging Study.

This paper examines the relation of two personality characteristics (dominance and anger) to hormones in normally aging men. The relation of the Jackson Personality Research Form E Dominance subscale and the Spielberger Anger Expression scale to serum levels of 17 endocrine variables, including testosterone (T) and dihydrotestosterone (DHT), cortisol, and prolactin, was examined in 1709 men aged 39 to 70 years randomly sampled from the Boston Metropolitan Statistical Area. Canonical correlation analysis resulted in the identification of a personality profile characterized as dominant with some aggressive behavior that tends to correlate with a hormonal pattern labeled the "availability of androgens." These results partially support previous findings in animals, adolescents, and criminal populations that "aggressive dominance" is related to testosterone.
