This publication provides an overview of IFRC’s project: “Provision of quality and timely psychological first aid to people affected by the Ukraine crisis in impacted countries.” Carried out with the support of the EU4Health programme, this historic partnership between the European Commission and the IFRC, implemented on the ground by 28 National Societies, stands as one of the largest responses to mental health challenges ever implemented by the International Red Cross and Red Crescent Movement (the Movement).  This publication outlines the project’s key approaches and achievements and provides recommendations for future initiatives. It illustrates how the project evolved over time – continuously adapting and refining its methods – to deliver effective, impactful and sustainable support that has significantlyimproved the mental health and wellbeing of people affected by the conflict in Ukraine.
