Significant moderators of the relationship between DE and longitudinal cortical thickness. Unstandardized parameter estimates along with standard error values are presented for the best fit model predicting left ROI and right ROI thickness from discriminatory experiences (DE), time from first scan, scanner, and significant moderators of interest. P-values for fixed effects are calculated using the Kenward-Roger method (Halekoh and Højsgaard, 2014) and are FDR corrected for multiple comparisons across hemispheres. In both hemispheres, DE, time (in months) from first scan, age at first scan, age2, gender, race/ethnicity, and scanner were significant predictors of cortical thickness. Likelihood ratio tests indicated that other moderators of interest (LES, clinical group, baseline P2 SOPS scores) did not improve model fit. P-value terms: ns p > 0.05; * p < 0.05; ** p < 0.01; *** p < 0.001.
