Associations between DE and demographic and clinical characteristics. All statistics indicate the relationship between discriminatory experiences (DE) and the characteristic listed (t-test, F-test, or Spearman’s correlation). DE scores ranged from 0 to 6. Baseline (BL) measures were calculated for all 716 study participants; follow-up measures were calculated for participants who completed at least one assessment following their first imaging visit (N = 615). P-value terms: ns p > 0.05; * p < 0.05; ** p < 0.01; *** p < 0.001.

| Clinical Group (HC, CHR-NC, CHR-C) | Mean HC = 1.7, Mean CHR-NC = 2.7, Mean CHR-C = 2.9, F = 21.1, *** |
