The Effects of Neurofeedback Training on Concentration in Children with Attention Deficit / Hyperactivity Disorder

This study investigated the effects of neurofeedback training on concentration in children with attention deficit/ hyperactivity disorder (ADHD). A single-subject ABA' experimental design was used to determine the effects of neurofeedback training. The participants of the study were three boys with ADHD. In the intervention phase after the baseline assessment, participant 1 and 3 trained neurofeedback for twelve sessions, and participant 2 trained ten times. The EEG was recorded during each session and was analyzed for relative power spectrum by beta/theta ratio. The concentration behaviors were measured on a 10-second interval scale during 15 minutes. The concentration was assessed using Auditory Continuous Performance Test (ACPT), and the ADHD symptoms were assessed by the Conners Teacher Rating Scale-Revised (CTRS-R) in pre and posttest. The data were visually analyzed using graphs and descriptive statistical analysis. The results of the study suggest that, after the neurofeedback training sessions, the participants showed a significant increase in their concentration behaviors. The scores of ACPT and CRTS-R were improved as well. However, no significant EEG change was observed, and no correlation of EEG with concentration behaviors was established.
