If the diagnosis of attention deficit/hyperactivity disorder was given, Achenbach System of Empirically Based Assessment (ASEBA) and Children’s Behaviour Checklist (CBCL) were administered to diagnose externalizing problems. Among those who had externalizing symptoms in the Achenbach questionnaire, 45 people were selected to participate in the research and were randomly divided into three groups of 15 people. The experimental groups were trained for one hour per week for 10 weeks, while the control group did not receive any training. The mixed analysis of variance statistical test was used to analyze the data. <strong>Results:</strong> The findings showed that there is no significant difference between the mean externalization score of CPRT and CBC experimental groups (p &lt; 0.05), but this difference is significant between the CPRT and CBC experimental group and the control group (p &lt; 0.05). <strong>Conclusion:</strong> It can be concluded that both methods of joint behavioral counseling model and treatment based on parent-child relationship have been effective on externalizing symptoms in students with attention deficit/hyperactivity disorder.</p> joint behavioral counseling model, use of games based on parent-child relationship, externalizing syndrome, attention deficit/hyperactivity disorder https://journals.kmanpub.com/index.php/aftj/article/download/531/516
