Childhood gender-typed behavior and emotional or peer problems: a prospective birth-cohort study.

Overall, more female-typical behaviors were generally associated with greater subsequent emotional and peer problems, for both boys and girls. Future studies should investigate factors that reduced these associations, as well as potential negative effects of female-typical behaviors or advantages of male-typical ones. As this was a 14-year longitudinal study, the relationships between gender-role behaviors and emotional/peer problems warrant further research despite the small association sizes.
