Bem Sex-Role Inventory
The Bem Sex-Role Inventory (BSRI) was constructed by the early leading proponent of androgyny, Sandra Bem (1977). The BSRI is one of the most widely used gender measures. Based on an individual's responses to the items in the BSRI, they are classified as having one of four gender role orientations: masculine, feminine, androgynous, or undifferentiated.
An androgynous person is a female or male who has a high degree of both feminine (expressive) and masculine (instrumental) traits. A feminine individual is ranked high on feminine (expressive) traits and ranked low on masculine (instrumental) traits. A masculine individual is ranked high on instrumental traits and ranked low on expressive traits. An undifferentiated person is low on both feminine and masculine traits.
