Abstract

Background: The purpose of this study was to compare the effectiveness of Transcranial Direct Current Brain Stimulation (tDCS) and computer-based cognitive rehabilitation on improving impulsivity in children with attention deficit/ hyperactivity disorder.

Materials and Methods: The current research design was quesi-experiment with pre-test-post-test and control group. 60 children with attention deficit/ hyperactivity disorder were selected by purposeful sampling and randomly replaced in three groups: experiment 1, experiment 2, and control (20 people in each group). Data were collected using Connors Parent Rating Scale (1978), Raven's Progressive Matrices Test (2000) Test and Barrett's impulsivity questionnaire (1995). The subjects of the first experimental group received Transcranial Direct Current Brain Stimulation (tDCS) and second experimental group also received Captain Log's rehabilitation intervention. The control group did not receive any intervention.

Results: The results showed that there is a significant difference between the groups impulsivity (P<0.05). The experimental groups of transcranial direct current brain stimulation (tDCS) and computer-based cognitive rehabilitation had lower impulsivity compared to the control group. Also, by controlling the effect of the pre-test in the two experimental groups, there is significant difference between the two methods of transcranial direct current brain stimulation (tDCS) and computer-based cognitive rehabilitation (P<0.05).

Conclusion: According to the results, it can be said that the intervention of transcranial direct current brain stimulation (tDCS) and computer-based cognitive rehabilitation was effective in improving the impulsivity in children with attention deficit/ hyperactivity disorder. Therefore, both interventions can be used to improve the impulsivity in children with attention deficit/ hyperactivity disorder.
