Associations between sexual identity stigma and positive sexual identity, and depression among men who have sex with men in China: A mediation analysis using structural equation modelling.

Purpose: High levels of depression are common among men who have sex with men (MSM) in China, and there is limited research on the relationship between MSM stigma and depression. Guided by the psychological mediation framework, to explore the relationship between stigma and depression among MSM and how positive sexual identity plays a role in it, we tested this model whether: 1) enacted MSM stigma, perceived MSM stigma, and positive sexual identity are associated with depression; 2) their effects on depression are mediated through resilient coping and social support; and 3) perceived MSM stigma is a mediator of the effects of enacted MSM stigma and positive sexual identity on depression.

Methods: We conducted mediation analyses using structural equation modeling (SEM) on data from a cross-sectional survey conducted among 1014 MSM recruited using a non-probability sampling method in December 2022.
