Sex-role attributes, perceived competence and the development of depression in adolescence.

Studies are described which investigated the relationship of sex-role traits to age trends and sex differences in depression in adolescents. Psychological masculinity was negatively related to the level of depression in males and females, and evidence which indicates that this relationship is mediated by a link between masculinity and perceived competence is presented. The level of masculinity was stable across the age ranges studied, but was related to an increasingly higher rate of depression in females than males. It is therefore argued that a sex difference in masculinity arises prior to adolescence, but interacts with other factors which influence vulnerability to depression during the teenage years, thus bringing about the sex difference in depression.
