Note. WTAR = Wechsler Test of Adult Reading total score; WASI–II = 4-subtest IQ; MATRICS = composite score; CAINS = Clinical Assessment Interview for Negative Symptoms; MAP = Motivation and pleasure subscale; EXP = Expression subscale; CDSS = Calgary Depression Scale for Schizophrenia total score; BPRS = Brief Psychiatric Rating Scale; SLOF = Specific Level of Functioning Scale; Chapman RSAS - Chapman Revised Social Anhedonia Scale. Two-sample Kolmogorov-Smirnov (KS Z) tests were used to compare groups on neurocognition because the homogeneity of variance assumption was violated.
