The psychometric adequacy of three sex role instruments was determined by performing a factor analysis on the items in the Bem Sex Role Inventory, the Personal Attributes Questionnaire, and Heilbrun's Masculinity and Feminity Subscales. Subjects were 400 college students who responded to 116 bipolar items from the three instruments. The eleven factor solution which emerged did not demonstrate the psychometric adequacy of the three instruments and suggested that sex roles may require multidimensional measurement. (Author/RL)
