Bivariate Pearson correlations between the total scores on the Hamilton depression rating scale (HDRS), the overall multidimensional perfectionism scores as well as its subscales concern over mistakes (MPS-CM), doubt about actions (MPS-DA), personal standards (MPS-PS), the trait scores (STAI-T) of the state-trait anxiety inventory and the ERN amplitudes at Fz and Pe amplitudes at Pz for all patients (n = 39)
