Race bias S1 – treatment rating for Black patients at session one; SES bias S1 – treatment rating for low SES patients at session one; SE – standard error of the estimate; Int. Black – tailored intervention for race bias; Int. SES – tailored intervention for SES bias; Int. Other – non-race/SES intervention.
