Note.

Interrelations between participant characteristics were evaluated using Pearson correlations for continuous-continuous variable associations, Point-biserial correlations for continuous-binary associations, Spearman correlations for continuous-ordinal and ordinal-ordinal associations, Phi coefficients for binary-binary associations, and Rank biserial coefficient for ordinal-binary associations. Discrimination = Day-to-Day Unfair Treatment Scale; Stress = Perceived Stress Scale; Depressive symptoms = Center for Epidemiological Studies Depression 10-item scale. REF= Reference group.
