Stigma, secrecy, and discrimination: ethnic/racial differences in the concerns of people living with HIV/AIDS.

The HIV Stigma Scale is a measure that assesses stigmatization perceived and experienced by people living with HIV/AIDS (PLWHA). Using Item Response Theory (IRT) methodologies, the present study examined HIV Stigma Scale responses from 224 Black and 317 White PLWHA to determine whether cross-cultural differences exist in responses to items of the scale. IRT analysis revealed that eleven out of forty items functioned differently across groups. Black respondents had a higher probability of indicating greater stigmatization on items that described situations in which others discriminated against them, and White respondents had a higher probability of indicating greater stigmatization on items that described a resolve to keep their status a secret and fears of interpersonal rejection. These differences suggest that PLWHA have different experiences of stigma based on their ethnic/racial background, either because of cultural differences or the ways in which the participants interpreted items of the HIV Stigma Scale.
