Measuring attitudes regarding bisexuality in lesbian, gay male, and heterosexual populations.

Five studies on the development and validation of the Attitudes Regarding Bisexuality Scale (ARBS) were conducted. Factor analysis of an initial pool of 80 items yielded 2 factors assessing the degree to which bisexuality is viewed as a tolerable, moral sexual orientation (Tolerance) and a legitimate, stable sexual orientation (Stability). Three forms of the ARBS were created: a form to assess attitudes about female and male bisexuality (i.e., ARBS-FM) and forms to assess attitudes about female bisexuality (i.e., ARBS-F) and male bisexuality (ARBS-M). These forms evidenced moderate-to-high internal consistency reliability in both lesbian and gay samples and heterosexual samples. In heterosexual women and men, subscales were most strongly related to attitudes toward lesbians and gay men; frequency of religious attendance; political ideology; and prior contact with lesbian, gay, and bisexual people. In lesbians and gay men, subscales correlated with prior experiences with bisexual people, desired contact with bisexual people, contact with heterosexual people, and sexual orientation identity.
