Worldwide Mental Health
The magnitude of mental health problems in children and adolescents has not been recognized sufficiently by many governments and
decision-makers. This paper reviews the epidemiology of these problems as a basis for planning of services; the situation of mental health
services for children and adolescents in the various regions of the world; the principles and strategies of intervention for mental health
disorders in children and adolescents; and the role of international organizations and advocacy groups. It is concluded that old myths,
treatments and policies are no longer to be tolerated and that there is now the opportunity to develop and implement evidence-based
interventions, modern training programs and effective policies.
Key words: Children, adolescents, mental health care, systems of care, global interventions
