Optimism, well-being, and perceived stigma in individuals living with HIV.

Given the significant psychological challenges posed by HIV-related stigma for individuals living with HIV, investigating psychological resource factors for coping with HIV-related stigma is important. Optimism, which refers to generalized expectations regarding favorable outcomes, has been associated with enhanced psychological adaptation to health conditions, including HIV. Therefore, this cross-sectional study investigated associations among optimism, psychological well-being, and HIV stigma in a sample of 116 adults living with HIV and seeking mental health services. Consistent with study hypotheses, optimism was positively associated with psychological well-being, and psychological well-being was negatively associated with HIV-related stigma. Moreover, results of a full structural equation model suggested a mediation pattern such that as optimism increases, psychological well-being increases, and perceived HIV-related stigma decreases. The implications of these findings for clinical interventions and future research are discussed.
