In order to assess the validity of the technique employed in selecting items for the Bern Sex Role Inventory (BSRI) 58 male and 62 female undergraduates took the BSRI under three different sets of instructions. Both males and females were able to produce extremely masculine and extremely feminine BSRI profiles which differed (p < .01) from their own BSRI profiles. The results support Bem's (1974) assertion that the BSRI Masculinity and Femininity scales are comprised of items which are consistent with widely held sex-role sterotypes.
