Two studies were conducted to evaluate newly developed measures of attitudes about adoption. The Attitudes toward Adoption Scale was developed, based on research literature, to investigate the attitudes of people with and without experience with adoption toward adoption. Eighty-six college students completed this scale and made open-ended comments about each item. The Gay and Lesbian Parents' Adoption Scale was developed to measure attitudes toward adoptions by gay and lesbian parents. This scale was administered to 299 college students. Initial findings from these studies indicate that both scales have acceptable validity and reliability. A limitation of the study was that the sample was extremely homogeneous, consisting primarily of young heterosexual female psychology majors who had not been adopted.
