An empirical research study based upon the expectancy-value model of Eccles and colleagues (1983) investigated the effect of gender-role orientations on psychological dimensions of female athletes' sport participation and the likelihood of their continued participation in a stereotypical masculine activity. The model (Eccles et al., 1983) posits that gender-role orientation is linked to the intention to persist or discontinue sport participation, which is acted upon indirectly through mediation by two motivational variables: an individual's perceived competence and the perceived value of the activity. Three models were compared to test this mediation hypothesis with 333 female adolescent handball players in a prospective study. Results from structural equation modeling showed that a fully mediated model fit the data. The masculinity orientation positively predicted value for and perceived competence in handball, whereas the femininity orientation negatively predicted perceived competence. In addition, the two motivational variables negatively predicted intention to drop out. Finally, such intentions are the more proximal predictors of actual dropout.
