The aim of this study was to determine the effectiveness of executive function training (attention, response inhibition, working memory) on symptoms of anxiety, attention deficit and social skills in children with ADHD in Tabriz. This quasi-experimental study was performed in a pretest-posttest design with a control group. The statistical population included all primary school students in District 4 of Tabriz. From the mentioned population, a sample of 30 people was selected by purposive sampling method and randomly replaced in experimental and control groups. Both groups were then pretested and answered the CSI-4 questionnaire, Reynolds and Richmond Child Anxiety Scale (RCMAS) and the Social Skills Rating Scale (SSRS). In the next stage, the experimental group participated in 10 sessions (60 minutes) of executive function training, and then both groups underwent post-test. After collecting data, research hypotheses were analyzed using analysis of covariance using SPSS software. The results showed that executive function training was effective on symptoms of anxiety, attention deficit and social skills in children with ADHD.
