A pathway analysis of exploring how HIV-related stigma affects social capital among people living with HIV/AIDS in China.

HIV-related stigma is the most common and serious social problem which people living with HIV/AIDS (PLWHA) have to face. However, the impact of HIV stigma on social capital is not yet clear. Therefore, this study aims to understand the relationship between HIV stigma and social capital, and explore the mechanism of how HIV stigma influences social capital among Chinese PLWHA on this basis. An institutional based cross-sectional study was conducted from Nov 2015 to Jan 2016 in Wuhan, China, using a self-reporting questionnaire. A total of 552 PLWHA participated, and 520 valid questionnaires were included. Multiple linear regression analysis showed that lower education level, lower monthly income, higher internalized stigma, and anticipated stigma were significantly associated with lower social capital. Results of path analysis showed that although perceived community stigma has no direct effect on social capital, but it can affect social capital through internalized stigma and anticipated stigma. In conclusion, increased HIV stigma and reduced social capital are frequent among PLWHA in China. Perceived community stigma may cause PLWHA to internalize stigma and anticipate stigmatizing experiences, resulting in the reduction of social capital. These findings suggest that perceived community stigma should become the target of stigma intervention strategy among Chinese PLWHA.
