Since the introduction of the Bem Sex Role Inventory (BSRI), many studies have attempted to relate masculine and feminine characteristics to various personality dimensions. To determine the relationship between sex-role orientation and locus of control, undergraduate students (101 females and 83 males) completed the BSRI and the Adult Nowicki-Strickland Internal-External Scale. Results showed that the higher the masculinity score, the stronger was the internal orientation for females. For males, however, both masculine and feminine scores contributed significantly in determining the relationship between sex-role orientation and locus of control. The more sex-role congruent the male subjects were, the more internally oriented they were. The findings tend to support other research that found the masculine subscale of the BSRI to be more important in determining relationships with other variables than the feminine scale. (Author/RC)
