A new study by Canadian and Italian researchers, published in the journal European Child & Adolescent Psychiatry, shows that regular participation in organized sports between the ages of 6 and 10 may reduce defiant behavior in adolescence. The research was conducted by Matteo Privitera from the University of Pavia and his colleagues, including Linda Pagani from the University of Montreal.
Oppositional Defiant Disorder (ODD) is characterized by persistent disobedience, irritability and hostility toward adults and authority figures, and is more common in boys. These symptoms can complicate schooling, relationships and overall mental health. The researchers wanted to understand how early extracurricular sports may influence children’s behavior and provide practical strategies for communities.
Sports provide structure and routine, helping children develop self-control. Through training and competitions, children learn to take turns, follow rules and consider the actions of others. These skills gradually become habits that affect behavior at school and at home.
The study analyzed data from the Quebec Longitudinal Study of Child Development, including 1,492 children who regularly took part in organized sports under the supervision of coaches or instructors. Children’s behavior was assessed at the ages of 10 and 12, taking into account social and family context.
The results showed that boys who participated in sports regularly displayed fewer signs of defiance than those who were less consistent. No significant effect was found for girls, which the authors explain by their lower average tendency toward oppositional behavior in middle childhood.
Researchers emphasize that encouraging participation in structured sports activities can reduce the risk of behavioral problems and improve long-term mental health. Sports do not replace parenting, but they strengthen the positive influence of family and school, giving children safe opportunities to interact with peers and adults.
