Among children and young people, mental health and substance use disorders are the leading cause of disability worldwide (Erskine et al. 2015).  

Mental ill-health contributes to nearly half of the burden of disease in young people (Headspace 2011). A recent study found six of the top 10 reasons for referring a child to a paediatrician were mental health issues (Hiscock, et al. 2017). 

Half of mental health disorders start by age 14 and three quarters by age 24 (Department of Education and Training 2017). This indicates the importance of identifying and addressing mental health issues in children (Department of Education and Training 2017).  

A major study in 2015 found that the most common mental disorder in Australian children and adolescents was attention deficit hyperactivity disorder (ADHD), followed by anxiety disorders, major depressive disorder and conduct disorder (Lawrence et al. 2015).  

Victorian schools have a number of strategies to promote healthy minds and positive mental health, including creating safe environments, teaching social and emotional learning and recognising the important role that families play in promoting mental health (Department of Education and Training 2017). 

Approximately $200 million dollars is invested annually in schools and other settings to fund a range of services, including social workers and psychologists, to promote mental health in children(Department of Education and Training 2017). 

Intentional self-harm in young people

Intentional self-harm includes a range of behaviours that cause direct and deliberate harm to oneself, including non-suicidal self-injury, suicidal behaviour and suicide.  

Common motivations for deliberate self-injury include self-punishment and difficulties with emotion regulation (Centre for Suicide Prevention Studies 2010).  

Measuring the problem, however, is challenging because there are difficulties in identifying intentional self-harm cases in hospital data.  

Some people may choose not to disclose that their injuries from intentional self-harm, or they may be unable to do so because of the nature of their injuries or because their motives were ambiguous (Australian Institute of Health and Welfare 2014). 
 
Higher rates of self-harm occur in women, and intentional self-injury rates are particularly high for young women aged 15–24 years (Victorian Injury Surveillance Unit 2017).  

The 2015 Child and Adolescent Health Survey found self-harm was markedly higher in young people with major depressive disorder (Department of Health 2015).  

There has been a marked increase in rates of Victorian children and young people presenting for self-harm at emergency departments (Victorian Injury surveillance Unit 2017). This may in part be due to improved awareness of self-harm among hospital staff and the community more broadly.
