Post-traumatic Stress Disorder (PTSD) is frequent among people living with HIV/AIDS (PLWHA). Few studies have investigated social-psychological predictors of PTSD in China. This study aimed to examine relationships between social capital, stigma, resilience and PTSD among PLWHA in China, and to provide effective suggestions for PTSD intervention. A cross-sectional study of 520 PLWHA was conducted from November 2015 to January 2016. Survey data were collected using anonymous self-reported questionnaire. Multivariable analyses were used to examine related factors of PTSD, and causal mediation analyses were conducted to assess whether stigma and resilience were mediators. Results indicated that higher risk of PTSD was independent associated with stronger stigma, decreasing social capital and lower resilience. There was an indirect relationship of social capital on PTSD mediated through resilience and HIV-related stigma. Therefore, PTSD intervention programs should not only pay attention to the role of social capital on PTSD, but also attach importance to stigma and resilience on PTSD symptoms.
