Table 1 indicates descriptive data on performance of participants of both groups in Conners' scale and CPT-II before and after intervention and 8 weeks after treatment completion. Analysis of Variance (ANOVA) with repeated measurements showed that both interventions had significant effect on scores of ADHD (F = 330.63, p < 0.001), hyperactivity (F = 198.49, p < 0.001), inattention (F = 491.36, p < 0.001), and omission (F = 15.30, p < 0.001), but effect was not significant on oppositional behavior. The group/time interaction was significant for omission errors (F = 19.39, p < 0.001) and alpha enhancement protocol made more suppression. These results were maintained after an 8-week follow-up.
