PedANAM-CPS_UWA is calculated by taking the average of 9 battery accuracy scores; if PedANAM-CPS_UWA < 0.25, further evaluation is recommended.

PedANAM-CPS_PCA is calculated by taking weights of 0.29, 0.13, 0.45, 0.42, 0.26, 0.35, 0.33, 0.27 and 0.39 on battery accuracy scores of CDD, CPT, CS, LRS, M2S, MG, MATH, ST6 AND SPD respectively; if PedANAM-CPS_PCA < 0.25, further evaluation is recommended.

PedANAM-CPS_logit is calculated using the following formula: PedANAM-CPS_logit = −1.99 – 0.24*CDD - 0.21*CPT - 0.07*CS - 0.35*LRS + 0.19*M2S + 0.85*MG + 0.02*Math - 0.37*ST6 - 1.00*SPD; if PedANAM-CPS_logit > −2.7, further evaluation is recommended.

PedANAM-CPS_multiscore is calculated using the following formula: PedANAM-CPS_multiscore = 15.42 – 0.19*AC.SPD + 9.75*CVc.CPT + 7.29*CVc.M2S – 0.01*MNc.CDD; if PedANAM-CPS_multiscore > 0.09, further evaluation is recommended.

Where CDD = Code Substitution Delayed accuracy score; CPT = Running Memory accuracy score; CS = Code Substitution accuracy score; LRS = Logical Relations Symbolic accuracy score; M2S = Matching to Sample accuracy score; MG = Matching Grids accuracy score; Math = Math Processing accuracy score; ST6 = Memory Search accuracy score (6); SPD = Spatial Processing (simultaneous) accuracy score; AC.SPD = Percent of Accuracy in SPD, CVc; CPT=Coefficient of Variation in CPT; CVc.M2S=Coefficient of Variance in M2S; MNc.CDD=Mean Reaction Time in CDD.
