Although health inequities among Black same gender loving men (SGLM) are well documented (e.g., chronic psychological disorders, HIV, suicide), there are few accessible, culturally affirming, and community-led interventions designed to reduce these inequities. The present manuscript describes the process through which we developed iTHRIVE 365, a multicomponent health-promotion intervention designed by Black SGLM for Black SGLM. We utilized a community-based participatory research approach (CBPR) that included collaboration between THRIVE SS, a Black SGLM-run community-based organization, and a multisectoral team of public health, research, and digital design professionals to develop the intervention. A five-phase development process included four phases of focus groups and a technical pilot to assess community priorities and incorporate input on each feature of the intervention. Directed content analysis indicated that participants wanted a multicomponent and technology-mediated intervention that promotes health knowledge and motivation, Black SGLM social support, access to affirming healthcare, and housing and economic resources. iTHRIVE 365 combines multilevel and culturally affirming intervention features to combat the effects of oppression and ultimately promote Black SGLM's biopsychosocial health.
