School-based services delivered by teachers and other school-based professionals can help reduce mental health problems in primary-age children, reports a study published in the Journal of the American Academy of Child and Adolescent Psychiatry.
The findings are based on a meta-analysis of 43 controlled trials involving almost 50,000 primary school children. The study examined the overall effectiveness of school-based mental health services, as well as the relative effectiveness of various school-based intervention models that differed according to treatment target, format and intensity.
Overall, school-based services had a small to medium effect (effect size = +0.39) in reducing mental health problems. Interventions that targeted child behaviour problems demonstrated the largest effect sizes (+0.76). Interventions that were implemented multiple times per week were found to be more than twice as effective as those that were only implemented on a weekly (or less) basis.
