The 40 masculine and feminine items of 746 Bern Sex-Role Inventory (BSRI; Bern, 1974) were subjected to a principal axis factor analysis with varimax rotation. Results revealed a four-factor solution, indicating that the original BSRI items do not provide two unidimensional ratings of femininity and masculinity. However, some support is given to Bern's initial two-factor thesis in that two principal factors emerged: one consisting of items that were originally identified as feminine, the other consisting of items that were originally identified as masculine. Content examination of the two principal factors resulted in an interpretation of the factors as Interpersonal Sensitivity and Interpersonal Potency. Internal consistency and validity of these two scales were examined and found to be adequate.
