Sex role differences in self disclosure are more clearly defined than are gender differences. Students filled out a Bem Sex Role Inventory (BSRI) as part of an introductory course requirement. Males and females who scored as either androgynous or stereotyped were selected for four targets: mother, father, male best friend, female best friend. Some results were that: (1) androgynous persons disclosed more, (2) no sex main effect was found, (3) androgynous males disclose more on intimate topics to their fathers, (4) androgynous persons disclose more on imtimate topics to both best friend targets, (5) androgynous females disclose more on non-intimate topics to their fathers than do stereotypical females. The data suggest that self disclosure is a function of sex role and not of biological gender. The greater predictive value of androgyny over gender supports the major assumption that self disclosure is a function of sex role socialization. (BN)
