The Complexity of Youth Suicide and Prevention

There's a lot of misinformation out there about youth suicide. Suicide rates in young people nationally have decreased by about 20% from the mid 1990’s to 2004. Nova Scotia is a good case study. It is difficult to determine trends in youth suicide in Nova Scotia because of the small numbers involved, but total suicide rates as well as total suicide attempts in this province have decreased substantially between 1995 and 2004.

Why this has occurred is not clear. One explanation is that effective treatment of depression in young people may be an important factor. Studies have demonstrated a strong relationship between increased use of antidepressant medications and decreased suicide rates in youth. Evidence shows that both medications and psychological therapies decrease rates of suicide attempts in depressed youth. Recent research reports in both Canada and the USA indicate that when anti- depressant medication treatment in young people has decreased, suicide rates have increased. Treatment of depression in young people may effectively reduce suicide rates. 

Suicide behaviour is complex. Not all self-harm behaviours are suicide attempts. Self-harm behaviour in young people may not be related to suicide, but rather to deficient problem solving strategies, difficulties with emotional control or impulsivity. It is only recently that we have understood the need to differentiate the two in how we collect data. Treatment for young people who demonstrate self-harm behaviours may be different than treatments for youth who attempt suicide.

Self-harm behaviours reflect many mental disturbances and may be an important vehicle by which young people can access emergency care. Thus, increases in self-harm emergency visits may not reflect an increase in suicide as has been erroneously suggested, but may reflect other phenomenon such as: greater parental awareness of the importance of immediately addressing these behaviors; difficulty in access to specialty mental health services; inadequate delivery of child and adolescent mental health care in primary care; inadequacies in the capability to provide early identification and interventions for youth at risk for mental disorders; or others.

Suicide in young people is a complex problem that requires thoughtful, evidence-driven approaches to appropriately address. It is also an emotional issue raising substantial concern amongst parents, youth, care providers, policy makers and the public alike. There are some interventions that we know work to decrease suicide rates in young people.

One of the most important is improving the early identification and effective treatment of depression in youth. This includes enhancing the competencies of primary health care providers (doctors, nurses, social workers, psychologists, etc) in the diagnosis and treatment of adolescent depression. Training programs for school personnel including “gatekeeper” programs for teachers and linkages between schools and health providers to facilitate identification, rapid assessment and effective treatment may also decrease youth suicide. Restriction of access to lethal means (such as bridge barriers) is helpful as is reasonable and informed media reporting.

Youth suicide is an important public health problem. We must work together to better understand it and to apply what we know works. We need to avoid inciting public anxiety through media reports that are not based on a solid understanding of the issue and we need to support the further development of easily accessible and effective mental health care – not just in hospitals but in schools and community settings. We need to do the right thing – not just do something!
