Mental health is critically important to everyone, everywhere. All over the world, mental health needs are high but responses are insufficient and inadequate. The World mental health report: transforming mental health for all is designed to inspire and inform better mental health for everyone everywhere. Drawing on the latest evidence available, showcasing examples of good practice from around the world, and voicing people’s lived experience, it highlights why and where change is most needed and how it can best be achieved. It calls on all stakeholders to work together to deepen the value and commitment given to mental health, reshape the environments that influence mental health, and strengthen the systems that care for mental health.
