(I) The causes of depression differ in men and women. (II) Research shows that women usually internalize distress, while men externalize it. (III) Depressed women are more likely to talk about their problems and reach out for help. (IV) Depressed men often have less tolerance for internal pain and turn to some action or substance for relief. (V) Male depression is thus less obvious than female depression, as the male, instead of trying to deal with it, seeks to run away from it.
