The intervention comprises five levels: mental health promotion for the general population, preventive group activities, classroom-based interventions for specific subgroups, counseling by paraprofessionals for targeted subgroups, and specialized individual psychiatric treatment. A comprehensive monitoring and evaluation framework was utilized to assess the care package in four war-affected countries (Burundi, Indonesia, Sri Lanka, and Sudan). The evaluation yielded positive feedback from nearly 30,000 child beneficiaries across all settings.
