Brief reportTraining of slow cortical potentials in attention-deficit/hyperactivity disorder: evidence for positive behavioral and neurophysiological effects
Section snippets
Subjects
Thirteen children with ADHD, aged 7–13 years, participated in SCP training during their summer holiday. The training effects of this group were compared with those of a waiting-list group of 9 children with ADHD. Both groups were comparable with respect to age, gender, and intelligence (German version of the Wechsler Intelligence Scale for Children III); Tewes et al 2000); see Table 1.
All patients fulfilled DSM-IV criteria for ADHD (American Psychiatric Association 1994). Diagnoses were based
Results
There were no pretraining differences between the training group and waiting-list group on any of the behavioral, performance, and ERP variables [t(1,20) < 1.2; ns].
Pre- and posttraining comparisons are summarized in Table 2. For the FBB-HKS score, a significant group × time interaction resulted [F(1,20) = 4.4; p < .05]. In the training group, the FBB-HKS score was decreased by approximately 25% after training [pretraining–posttraining: .38 ± .35; t(1,12) = 3.9; p < .004]. The waiting-list
Discussion
In this study, the effects of a 25-session SCP training were investigated in children with ADHD compared with a waiting-list group.
To evaluate training effects, performance and ERP measures of a cued CPT task were studied. In cue trials, children in the training group showed a pronounced CNV increase after SCP training. Because no pretraining–posttraining CNV effect was found for the waiting-list group, a practice effect may be excluded. The CNV is thought to be related to the negativities that
