NAcc activation significantly moderated the link between election distress and depression symptoms for affected individuals. Analyses used a bootstrapping approach with 5000 samples, and significance was determined at 95% bias-corrected confidence intervals. All variables were continuous and centered before analysis, and the estimated effects are reported as unstandardized regression coefficients. A, Distribution by group of NAcc activation to feedback reward > loss extracted from the bilateral NAcc ROI (x = ±10, y = 10, z = −2, 8 mm³ spheres). Neural activation did not differ by group. B, Significant moderated mediation analysis. Election distress significantly mediated the relationship between discrimination and depression symptoms. NAcc activation significantly moderated the link between election distress and depression symptoms for affected individuals. C, Simple slope analyses showing that high NAcc activation ameliorated the relationship between election distress and depression symptoms for affected individuals. *p < 0.05, **p < 0.01, ***p < 0.001.
