Attention deficit hyperactivity disorder (ADHD) is one of the most common neuropsychological childhood disorders that causes inconvenience to children, families, and the society. The objective of the present research is to investigate the effect of teaching Couples' Communication Model on the symptoms of ADHD in 4-9 year-old students. For this purpose, 60 students suffering from attention deficit disorder/hyperactivity-impulsivity were selected using multi-stage cluster sampling method and randomly assigned into an experimental or a control group with equal proportion. The data were analyzed using inferential statistics method (Covariance analysis). The findings revealed that training parents in the Couples' Communication Model could significantly decrease the symptoms of ADHD in children (P< 0.05). It is recommended that this method be used as a non-pharmacological method to treat ADHD in children.
