Relationship between negative symptoms and neurocognitive functions in adolescent and adult patients with first-episode schizophrenia

Table 5 The correlation matrix of negative factor scores and the neuropsychological test measures on adolescent and adult first-episode schizophrenics

Adolescent False Discovery Rate: p (TMT 1) < p (TMT 2) < p (SCWT 3) < p (SCWT 1) < p (CT) < p (TE) < p (RE) < p (PE) < p (CPT 2) < p (SCWT 2) < p (CPT 3) < p (CPT 1) < p (CC) < .05 < p (RT of SCWT) < p (PE of CPT 3) < p (TT), while p (CPT 3) = .03 < .05*11/16 = .034 and p (CPT 1) = .038 > .05*12/16 = .0375. So CC and CPT 1 are not significant
Adult False Discovery Rate: p (SCWT 3) < p (RT of SCWT) < p (SCWT 2) < p (SCWT 1) < p (CT) < p (RE) < p (CPT 3) < p (TE) < .05 < p (CC) < p (PE) < p (TMT 2) < p (PE of CPT 3) < p (TMT 1) < p (CPT 1) < p (CPT 2) < p (TT), while p (TE) = .024 < .05*8/16 = .025
|r|∈[.8,1] means highly strong correlation, |r|∈[.6,.8) means strong correlation, |r|∈[.4,.6) means moderate correlation, |r|∈[.2,.4) means weak correlation, |r|∈[0,.2) means very weak correlation or no correlation
TT total trials, CT correct trials, TE total number of errors, PE perseverative errors, RE random errors, CC the number of completed categories, PE of CPT 3 perseverative errors of CPT 3, RT of SCWT reaction time of SCWT
*P < .05, **P < .01, the significance of the correlation coefficient
