Background: The growth and development of the child are essential and inevitable, and the growth of every child requires motor development.

Purpose: This study examines the relationship between motor self-motivation and attention-deficit hyperactivity disorder's symptoms in children with attention-deficit hyperactivity disorder. 40 people were selected by the convenience sampling method from the psychology centers of the province. The research method was descriptive-correlational. A questionnaire was used to collect data. Data were analyzed using Pearson correlation and linear regression.

Results: The results showed that there is a significant negative relationship between motor self-motivation and symptoms of attention-deficit hyperactivity disorder. The results of regression analysis also showed that motor self-motivation is able to predict the symptoms of attention-deficit hyperactivity disorder in children.

Conclusion: In general, the more children's motor motivation, the more minor attention-deficit hyperactivity disorder's symptoms.
