Theories of social integration and stress process posit that community involvement may buffer or may compensate the adverse effects of stigma on psychological well-being. In this article, the authors explore this thesis in a stigmatized and seldom studied group of HIV-positive Latino gay men. Specifically, they examine the effects of community involvement in AIDS and gay-related organizations (e.g., volunteerism and activism) and experienced homosexual stigma on three psychological well-being indicators (i.e., self-esteem, depression, and loneliness). The cross-sectional sample includes 155 HIV-positive men living in New York City and Washington, DC. Results suggest that experienced stigma attributed to homosexuality is associated with psychological well-being. Community involvement, however, seems to compensate the association between stigma and depression and loneliness, while buffering the association with self-esteem. Furthermore, community involvement appears to also heighten the perception of stigma.
