The AIDS Attitude Scale was developed in two stages. In the first stage, 67 items that were determined by an expert panel to have content validity were randomly ordered and administered to 164 student volunteers at a large southern university. Fifty-four individual items that correlated significantly with the total attitude scores were retained for the scale's final version. In the second stage, the revised scale was administered to 135 student volunteers to determine its internal reliability. Results showed that females and students age 21 and over were significantly more tolerant about AIDS than males and younger students. Preliminary factor analysis revealed three factors explaining about 45 percent of the variance in response patterns. These factors related to proximity to people with AIDS, moral issues, and social welfare issues. Table and 28 references. (Author abstract modified)
