Building a child-centred, multilayered MHPSS eco-system for conflict-affected children (Ukraine).

Objective: Aim: This article aims to propose a multilayered, child-centred Mental Health and Psychosocial Support (MHPSS) ecosystem model tailored for conflict-affected children (on example of Ukraine). The model integrates evidence-based interventions, multisectoral collaboration, and cultural adaptation to address acute psychosocial distress and foster long-term resilience, offering a replicable blueprint for humanitarian contexts.

Patients and methods: Materials and Methods: The development of the MHPSS ecosystem model was informed by a comprehensive review of theoretical frameworks, peerreviewed literature, international reports, and successful MHPSS interventions in humanitarian settings. The model synthesizes the Inter-Agency Standing Committee (IASC) pyramid of psychosocial intervention and Bronfenbrenner's ecological systems theory, contextualized through analysis of UNICEF and WHO reports, Ukraine's National the Action Plan for 2024-2026 and Target Model of the MHPSS System, and global best practices. An 11-stage implementation plan was formulated, incorporating adaptation, governance, capacity building, database/certification, supervision, quality assurance, and policy integration, guided by implementation science frameworks.

Results: Results: The proposed model operationalizes a coordinated, scalable MHPSS ecosystem centred on children, layered across family, school, service infrastructure, and policy. Through localization, community-driven delivery, and multisectoral governance, the model enhances cultural fit, professionalizes the MHPSS workforce, and embeds continuous quality improvement. Integration with Community Resilience Centres (CRCs) strengthens local service delivery and sustainability. The staged implementation plan provides a universal roadmap for bridging immediate psychosocial needs and long-term systemic resilience.

Conclusion: Conclusions: The multilayered MHPSS ecosystem represents a paradigm shift in addressing the psychosocial impact of conflict on children. By embedding evidence-based, contextually adapted supports within a sustainable multisectoral framework, the model offers significant potential to mitigate distress and promote resilience, serving as a foundation for future research and global replication.
