We investigate the role that instrumental and symbolic functions of attitudes play in the rejection of people infected with HIV. In a series of studies (total N = 431), we manipulate the symbolic component of AIDS, by comparing it to a fictitious disease that is identical in every way to AIDS, excepting its symbolic association with homosexuality and IV drug use. Two studies indicated that the symbolic component had no effect on either social distance or perceptions of disease severity. A third study indicated that instrumental aspects of severity, contagiousness, and treatability were significant determinants of social distance. A fourth study found that the stigma of association with homosexuality increased a mild disease's stigma. A fifth study showed that previous research showing the importance of a symbolic component in AIDS‐related attitudes may have relied on a confounded measure of the symbolic component of attitudes. These 5 studies suggest the importance of both instrumental and symbolic attitudes in illness. Instrumental functions seem to outweigh the impact of symbolic functions of AIDS‐related attitudes.
