*P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001. CES-D = Center for Epidemiological Studies Depression Scale (transposed); regression analysis with transposed CES-D and TxEQ variables. F-values represent the ANOVA for the full model. F change indicates the contribution of each additional block (i.e. the variable added in Block 2 and Block 3). Degrees of freedom for the F test on the full model = (5, 86). Effect size magnitude: small effect size 0.02 ≤ R² < 0.15; medium effect size: 0.15 ≤ R² < 0.35; large effect size: R² ≥ 0.35.
