Effectiveness of Cognitive behavioral group Play therapy and Transcranial Direct Current Stimulation on Executive Function of Working Memory And Response Inhibition of Children with Attention Deficit- Hyperactivity Disorder

The present study has been done with aim to investigate the effectiveness of Cognitive behavioral group Play therapy(CBPT)and transcranial direct current stimulation(tDCS)On executive function of working memory and response inhibition of children with (ADHD). In this quasi-experimental study with pre-test and post-test and control group,49 boys ADHD 6 to 11 years old were selected by Convenience Sampling method and from two schools in Islamshahr.In the following,By doing Stanford Intelligence Test and Conner’s Parent,13 people were excluded due to absence of entry criteria.The remaining 36 boys were randomly assigned into groups of intervention and control (each group included 12 subjects).Then, tests of N-Back for measures working memory and Go-No-Go was used for measures response inhibition Before and after interventions.Interventions included CBPT 8 sessions of 60 minutes and tDCS included 10 sessions of 10 minutes with intensity of 1 mA .Data were analyzed by Software SPSS version 23. After the removal of the effect of pre-test was determined that there was no significant difference between the intervention and control groups in the working memory scores(in the number of correct responses and action speed).Also,CBPT had no significant difference in any of the response inhibition scores compared to the control group, However,tDCS had a significant difference with the control group in the scores of action accuracy and action speed was. the CBPT method is not effective in improving active memory and inhibition of response,and tDCS method is only effective in improving response inhibition.children with ADHD disorders using tDCS can be more control their impulsivity.
