Practitioner Review: Effectiveness of indicated school-based interventions for adolescent depression and anxiety - a meta-analytic review.

Indicated school-based interventions are effective at reducing symptoms of depression and anxiety in adolescents immediately postintervention but there is little evidence that these reductions are maintained. Interventions delivered by school staff are not supported by the current evidence base. Further high-quality randomised controlled trials incorporating assessment of longer-term outcomes are needed to justify increased investment in school-based interventions for adolescent depression and anxiety.
