Mental illness is the number one health issue facing 14-25 year olds in England, which contributes to almost half the burden of disease in this age group (Kessler et al 2005, Kim-Cohen et al 2003). A total of 75% of all mental health disorders are established by the age of 18 which is a critical point of emotional, educational and social development. All nurses working with children and young people (CYP) across all health and social care settings should be familiar with national guidelines and the services available to treat CYP with mental health conditions such as depression.
