Thwarted belonging needs: A mechanism prospectively linking multiple levels of stigma and interpersonal outcomes among sexual minorities.

The association between stigma and adverse interpersonal outcomes is well established. However, the mechanisms underlying this association have yet to be comprehensively conceptualized and tested, in part because research has neglected to evaluate stigma across multiple levels. To address this gap, we examined whether stigma—measured at individual, interpersonal, and structural levels—prospectively affects loneliness and social support by thwarting fundamental belonging needs, using a longitudinal sample of 315 gay men. Results indicated that thwarted belonging needs prospectively mediated the association between interpersonal discrimination, internalized homonegativity, and concealment motivation and changes in loneliness and lack of social support. When indirect pathways were tested simultaneously, discrimination was uniquely associated with reductions in social support via thwarted belonging needs. In addition, the prospective association between objectively‐measured structural stigma (at the state and county levels) and loneliness and lack of social support was serially mediated by perceptions of structural stigma and thwarted belonging needs. To guide future work, we propose a model outlining pathways by which stigma, across multiple levels, may lead to adverse interpersonal outcomes by increasing relationally‐oriented biological, motivational, cognitive, affective, and behavioral mechanisms that affect belonging needs.
