This thesis discusses the current state of research regarding attitudes and behaviors toward lesbians and gay men and outlines the development and testing of the Behaviors Toward Gays and Lesbians Scale (B-GAL). Establishment of internal consistency reliability and construct validity (convergent, discriminant, and predictive validity, as well as factor analysis) was determined on a sample of 175 female and male heterosexual college students. Results suggested a highly internally consistent and valid behavioral measure consisting of three factors. The thesis also discusses the use of the B-GAL in providing a preliminary assessment of college students' behaviors toward lesbians and gay men.
