Measuring mental health for adolescents and young people at the population level

Last update: May 2026

Mental health conditions are a leading contributor to the burden of disease among adolescents and young people. Yet, data on the prevalence of adolescent and youth mental health conditions remain sparse, especially in low- and middle-income countries (LMICs). These data are urgently needed to guide strategic actions to address mental health needs among youth through effective policies and programmes.

The Measuring Mental Health among Adolescents and Young People at the Population level (MMAPP) initiative was developed by UNICEF and partners to address the critical lack of reliable data and tools for assessing adolescent and youth mental health at the population level.  UNICEF’s MMAPP initiative aims to improve the quality and availability of population-level data on key policy-relevant mental health and psychosocial wellbeing domains for adolescents and young people aged 10-24.
