The same analyses were carried out for scores at the midline-parietal region (Table 1, right). Comparing delta components, for disinhibitory disorders (ADHD, ODD, CD, AAB), EVK was always associated with smaller QICu than PLF, indicating that EVK was the better predictor of these disorders. The opposite relationship was evident for SUDs (NicD, AlcD, DrgD, Any-SUD) and Any-EXT; PLF accounted for more variance in diagnoses than did EVK. Turning to theta at the parietal site, across the board, thetaPLF prediction models were associated with better model-fit than thetaEVK, suggesting that thetaPLF more strongly predicts all of the externalizing disorders. Additionally, the ORs for PLF were significant for all of the individual disorders and composite diagnostic groups, while EVK ORs was significant in nearly all cases. One standard deviation decrease on deltaEVK, deltaPLF, thetaEVK, or thetaPLF was associated with a 34% to 44% increase in odds for having an externalizing diagnosis (Any-EXT).
