Mental health

Mental health evidence and research (MER)

The Mental Health: Evidence and Research team (MER) at WHO is deeply committed to closing the gap between what is needed and what is currently available to reduce the burden of mental disorders worldwide and to promote mental health.

The MER team transforms this objective into action through the following core projects: Atlas, WHO-AIMS and Mental Health in Emergencies. All of these projects aim to increase the information and evidence base on mental health. In turn, this information can be used to strengthen mental health care systems which will result in better care and services to individuals and communities. Detailed information is provided on each of these projects through the links below.

Core projects

Mental Health Atlas

Mental Health Atlas Project is designed to collect and disseminate data on mental health resources such as policies, plans, financing, care delivery, human resources, medicines, and information systems in the world. The project started in 2001 and the data was updated in 2005, 2011 and 2014.

Scalable psychological interventions

In recent years, a range of scalable psychological interventions have been found to be effective for people suffering disabling stress, depression and anxiety. WHO is working to seek to develop, test and/or disseminate such interventions as public goods.

WHO-AIMS

The World Health Organization Assessment Instrument for Mental Health Systems (WHO-AIMS) is a new WHO tool for collecting essential information on the mental health system of a country or region. The goal of collecting this information is to improve mental health systems and to provide a baseline for monitoring the change.

Mental Health in Emergencies

The target group for WHO work on mental health in emergencies is any population exposed to extreme stressors, such as refugees, internally displaced persons, disaster survivors, and terrorism, or war-exposed populations.
