A comparison was made of the sex roles of homosexual and heterosexual men and women on the Bem Sex Role Inventory, Personality Attributes Questionnaire, Personality Research Form Androgyny Scale, Adjective Checklist Masculinity and Femininity Scales, Extended Personality Attributes Questionnaire and Undesirable Characteristics Scale. The results indicated that homosexuals and heterosexuals differ in their response to different aspects of sex roles. The most consistent difference was the greater femininity of male homosexuals in respect to male heterosexuals. Other differences were scale-specific and the low interscale comparability indicated such scales should not be used interchangeably. Differences between results of studies comparing sex roles of the homosexuals and heterosexuals appear attributable to sample heterogeneity and distinctions between sex-role scales.
