What this trial studies

This project aims to address rising mental health issues among elementary school children and work-related stress in teachers by implementing the PAX Good Behavior Game in Swedish classrooms. The study will involve a cluster-randomized controlled trial with 28 schools and 84 teachers, where some will receive training in PAX while others will implement a control intervention. The effectiveness of PAX on student well-being and teacher stress will be evaluated over time, with both groups eventually using both interventions. The design allows for a comprehensive assessment of the long-term impacts on both students and teachers.

Why it matters

Potential benefit: If successful, this intervention could significantly enhance the mental well-being of students and reduce stress among teachers.

How similar studies have gone: Previous pilot studies have shown positive outcomes with similar interventions, indicating potential for success.
