The
reductions in
aggressive behaviour reported here could be attributable to change in the school's management
of child
behaviour or an increase in extracurricular activities which may, themselves, have preventive effects.4 None the less, the effects
of reducing media exposure and its effect in combination with other effective school based programmes5, 6 merit additional studies.
In a randomized trial with 246 children in 20 Head Start classrooms, children exposed to the PATHS program had higher emotion knowledge skills and were rated as more socially competent and less socially withdrawn at the end
of the school year.26 When PATHS was implemented along with a language and literacy curriculum in a separate study in 44 Head Start classrooms, significant
reductions in children's
aggressive behaviour were also observed.27
