Compiles global data on mental health systems, including policies, services, workforce, and financing. It enables countries to track progress, identify gaps in care, and benchmark against international targets, supporting efforts to strengthen mental health systems and improve access to services. Country level data is presented in the country profiles available on the website.

An international initiative launched in 2018 to improve the consistency and quality of data on adolescent health and well-being worldwide, addressing longstanding gaps in how the needs of young people aged 10–19 are understood and monitored. Developed in collaboration with key UN partners, it establishes a standardized framework of indicators across multiple domains, including health outcomes, behaviours, and social determinants. Its relevance to child and adolescent mental health lies in its holistic approach, which embeds mental health within broader measures of well-being rather than treating it in isolation. By incorporating indicators related to emotional well-being, risk exposure, and environmental influences, GAMA enables more reliable tracking of mental health needs and highlights the complex factors shaping outcomes during adolescence—a critical developmental period when many mental health conditions first emerge. This integrated, data-driven approach supports more effective policy, prevention, and service planning, ultimately strengthening global efforts to promote mental health and well-being among children and adolescents

Synthesises key data on the mental health of children and adolescents across the European Union, providing a clear overview of prevalence, trends, and major risk and protective factors. It brings together evidence on issues such as anxiety, depression, and the impacts of social, economic, and environmental determinants, helping to highlight the scale and nature of mental health challenges facing young people in the EU context.

A comprehensive regional data synthesis, bringing together the latest available evidence on child and youth mental health (CAYMH) across the WHO European Region. It compiles and analyses data on population needs, emerging trends, and the current state of support systems, including governance, workforce capacity, service provision, and quality of care (QoC). By consolidating this information, the report both reinforces existing recommendations and identifies key gaps, proposing nine additional actions to strengthen the quality and effectiveness of care.

A structured approach to assessing needs, services, and system capacity across sectors. It supports a comprehensive understanding of how determinants, service provision, and coordination mechanisms interact, enabling the identification of gaps and priority areas for action. While originally developed for diverse country contexts, the approach is adaptable to European settings and can strengthen evidence-informed policy development by supporting systematic analysis of child and adolescent mental health systems and their underlying drivers.

Practical guidance document designed to support governments and institutions in systematically assessing how proposed laws, policies, programmes, and services may affect the rights and well-being of children and young people. It outlines a structured, evidence-based process for analysing potential and actual impacts, grounded in the United Nations Convention on the Rights of the Child, and emphasises the importance of using both quantitative and qualitative data, including the views and experiences of children themselves

A comprehensive guidance document that supports countries in designing and implementing coordinated approaches to mental health for children, adolescents, and caregivers. It is grounded in a social ecological model and outlines a continuum of care spanning prevention, promotion, and treatment. The framework emphasises the need for collaboration across sectors—including health, education, child protection, and social welfare—and provides practical guidance on strengthening systems, services, and workforce capacity to deliver integrated MHPSS support.

Evidence-based recommendations on interventions that promote mental well-being and prevent mental health conditions among adolescents. Drawing on systematic reviews, the resource outlines effective approaches across settings—such as schools, families, and communities—supporting countries in implementing interventions that are both impactful and appropriate to adolescents’ developmental needs.

Thiis series of guidance documents supports countries in developing, implementing, and evaluating comprehensive mental health policies and strategic action plans. It provides a structured framework grounded in evidence and best practice, covering key components such as governance, service delivery, financing, and monitoring, to help strengthen national mental health systems.
