Abstract in brief

  • The study tracked physical aggression (PA) in Canadian children from age 2 to 11 and identified three main developmental patterns: a low desisting group, a moderate desisting group, and a high stable PA group, with the majority showing decreasing aggression over time.
  • About one-sixth of children, mainly boys from low-income families and those with less educated mothers, were in the high stable PA group, indicating persistent and frequent physical aggression that did not decline as seen in typical development.
  • Factors like being male, coming from disadvantaged backgrounds, and experiencing hostile or ineffective parenting increased the likelihood of belonging to the high PA group, suggesting that family environment and social risks can influence aggressive behavior development.]
