Introduction: Since 2019, the Mental Health for Ukraine (MH4U) project supports the process of reforming mental health services. With the COVID pandemic and the full-scale invasion by Russia, the needs for more accessible and better-quality services for Ukrainian population has dramatically increased. The MH4U project has evolved around those emerging challenges into a large movement with a wide geographic and thematic scope. Methods: The project seeks to facilitate increased delivery of mental health services within the community. The project aims to facilitate an optimal mix of comprehensive services, which make use of informal and formal care and empower patients to participate in decision making regarding their health and treatment. Together with government stakeholders, the project promotes human rights based mental health care, which is informed by evidence and is provided inside the communities. Results: National and oblast authorities deliver an improved legal framework, institutional support, coordination and leadership for community-based mental health care. Mental health service providers deliver more evidence-based services accessible and coordinated across sectors and levels of care. This was achieved through several capacity building programmes for professionals from health, social, psychology and educational sector on modern approaches to mental health care, prevention and promotion. In the Capacity building activities, the project trained 4,567 community mental health providers, clinical and non-clinical staff in intensive training courses (8 hours +) with mixed methodologies (64% online and 36% offline). The face-to-face modules contained several simulation exercises. The online learning platform with 33 courses and webinars - using modern instructional design methods - has 10,611 subscribed learners. Three online schools and conferences with live e-training content of at least 14 hours duration each were organized and provided for 731 professionals. Interactive face-to-face learning events were delivered to 827 young people in schools and youth-friendly spaces. Ukrainian mental health professionals and decision makers participated in exchanges during study tours and conferences abroad (Moldova, Ireland, Portugal, Czech Republic, and Lithuania).
