The development of this Operational Roadmap has been driven by a growing consensus in Ukraine on the need to prioritize activities that are urgently required to address the mental health and psychosocial needs of the country’s population and also the importance of basing the response on existing structures, resources and innovations introduced in reforms in past years. According to this consensus, new resources mobilized by and for Ukraine should complement existing ones, in line with the national vision and with best international standards, and should be planned in a way that further strengthens the country’s mental health system. The Government of Ukraine is committed to urgently addressing the mental health and psychosocial needs of the population, under the auspices of the First Lady of Ukraine and the leadership of the recently established Intersectoral Coordination Council for Mental Health and Psychological Assistance to Victims of the Armed Aggression of the Russian Federation against Ukraine (referred to in this document as the Intersectoral Coordination Council). This Roadmap has been developed following a series of consultations with Ukrainian authorities and national and international agencies working in the area of mental health and psychosocial support (MHPSS) and engaged in emergency response in Ukraine. The consultation process was organized by the Ministry of Health of Ukraine (MOH) and supported by WHO Ukraine, under the auspices of the First Lady of Ukraine and in collaboration with the MHPSS Technical Working Group of Ukraine (MHPSS TWG Ukraine) and the IASC MHPSS Reference Group (IASC MHPSS RG), and building on substantial advances in the mental health sector under existing programmes in the country. The Roadmap is informed by international technical guidance and national policies and plans, including the IASC Guidelines on MHPSS in Emergency Settings, the Minimum Services Package for MHPSS in Emergencies (MHPSS MSP), the IASC Common Monitoring and Evaluation Framework, the World Health Organization (WHO)’s Comprehensive Mental Health Action Plan 2013– 2030, the WHO European Framework for Action on Mental Health, the Concept for Development of Mental Health Care in Ukraine until 2030, the National Mental Health Action Plan for 2021–2023 and the National Recovery and Development Plan. Informed by the overall goal of MHPSS assistance in Ukraine – to reduce suffering and improve the mental health and psychosocial well-being of the affected population – the Roadmap aims to provide a consolidated overview of envisioned MHPSS priorities, informed by the local context and the vision of the Government of Ukraine together with national and international partners, and with the best available evidence and resources, to all MHPSS stakeholders already engaged in or joining emergency response and recovery efforts in Ukraine. As well as information on the context in Ukraine, the Roadmap includes: • a list of evidence-based MHPSS interventions and services contextualized and introduced in Ukraine in recent years (described in Table 1) and • a set of multisectoral actions to scale up MHPSS services in both the short and longer terms, informed by available evidence, international technical guidance and expert consensus (described in Table 2).
