Echo: Optimizing a Group-based School Intervention for Children With Emotional Problems

The present study (Echo) will promote much needed research and innovation that optimize service provision in first line health services for the alarmingly high number of school children who suffer from clinical and subthreshold levels of anxiety and depression. The effect of different versions of an evidence-based intervention for this group of children will be tested using a cluster randomized design involving 40 schools across Norway. The aim is to create a framework that allows more evidence-based psychosocial interventions to be provided at a lower cost to society. Echo will provide knowledge about three main evidence gaps for children: (1) The effect of school-based preventive interventions on anxiety and depression; (2) The effect of feedback informed systems, and; (3) the effect and cost-effectiveness of digital health interventions using online sessions and virtual reality technology.
