Internalized Homophobia, HIV Knowledge, and HIV/AIDS Personal Responsibility Beliefs: Correlates of HIV/AIDS Discrimination among MSM in the Context of Institutionalized Stigma.

There exists a paucity of research on the psychosocial risk factors of HIV/AIDS among men who have sex with men (MSM) in settings where they are stigmatized or face prosecution. The present study investigates discrimination against people living with HIV (PLHIV), internalized homophobia, HIV/AIDS personal responsibility beliefs and HIV knowledge in a purposive sample of 106 self-identified MSM obtained through a web-based survey disseminated by two voluntary welfare organizations. Results indicate that internalized homophobia is positively associated with discrimination against PLHIV. Internalized homophobia also substantially mediates the effect of HIV/AIDS personal responsibility beliefs on discrimination against PLHIV, highlighting the confounded nature of HIV/AIDS and homosexual stigma in a setting where stigma is deep-rooted and institutionalized. Internalized homophobia may thus serve as a barrier to the effectiveness of HIV prevention efforts among MSM in Singapore.
