Suicide is the leading cause of death for young Australians and a national public health priority.1,2 Repeat suicide attempts increase the risk for dying by suicide;3 however, thoughts and behaviours related to suicide often go undetected and unreported. This short article presents the findings of Australian longitudinal research into suicidality and help-seeking behaviours, and provides strategies to guide practitioners working with young people.

What’s the research about?

Between ages 12–18, many young people first start self-injuring and may repeatedly do so.4 Recorded suicides among Australian children younger than 14 are rare but from 14 years onwards mental health issues, including self-injury, increase.5 Many young people who think about suicide or hurt themselves do not seek help,6 and more information is needed on their contact with formal and informal sources of help. Particular groups are known to be at higher risk for attempting suicide in Australia: girls; those from low socio-economic backgrounds; and Indigenous children.7,8,9 These groups may require more targeted prevention or intervention. This research identified how many young people struggle with suicidal thoughts or attempt suicide and help seeking for emotional difficulties.

Growing Up in Australia: The Longitudinal Study of Australian Children (LSAC) is a nationally representative cohort study that has followed over 10,000 children since birth (B cohort) and age 4–5 (K cohort) since 2004. Every two years, these children and their parents answer questions relating to their health and wellbeing, relationships and school experiences. Longitudinal data can help us gain better insights into how patterns of self-injury, including thoughts and behaviours, may or may not change over time, in order to identify how and where to best intervene.

What are the main findings?

Data from LSAC K cohort at ages 14–15 and 16–17 were used to understand patterns of suicidality. These young people reported on suicidal thoughts and behaviours experienced in the previous 12 months.

Occurrence of suicidal thoughts and behaviours over time

Approximately 17% had thought about taking their own life, 14% had planned a suicide, and around 10% had made a suicide attempt between the ages of 14 and 17. For those who had made an attempt, around two-thirds made one attempt (~65%) and one-third made two or more attempts over the two-year study period.

Of those who had made a suicide attempt in the previous year, 16% at ages 14–15 and 20% at ages 16–17 indicated the resulting injury, overdose or poisoning was treated by a doctor or nurse.

Help-seeking behaviour and intentions

Friends and parents were the most common sources of help for emotional problems among young people who had attempted suicide. Almost three-quarters reported seeking help from friends (74%) and nearly half from parents (49%). A small proportion reported seeking professional/specialised help (10% from a GP; 8% from a phone helpline). However, young people who had attempted suicide were less likely to seek help from their parents compared with those who hadn’t attempted suicide. Those who had attempted suicide reported they would be most likely to seek help from a friend in the next four weeks, on average, if they had emotional problems.

What do the findings mean?

Ages 14–17 is a period of vulnerability when almost a fifth of young people think about suicide. Effective, targeted and adjustable strategies are needed in settings where young people spend a lot of time and that are pivotal in their growth and development.

Many young people who experience suicidality may not seek help and, where they do, other young people are the most likely source of support for those experiencing emotional problems. Therefore, comprehensive mental health literacy education, including recognising signs someone may be struggling, and how to talk about those thoughts/feelings and seek help could be a successful strategy. This may reduce stigma around mental ill-health and suicidality. It may also increase their ability to appropriately respond to disclosures of suicidality and direct their friends to support services or resources. Resources are listed below to support practitioners in developing young people’s mental health literacy.

Schools are priority settings for suicide prevention efforts, as a connection point for young people and practitioners who support their mental health. Practitioners need training in recognising signs of suicidality, how to initiate and have conversations about suicide, and how to assess suicide risk. There is no evidence that suggests asking someone about suicide triggers suicidality.10,11 Resources are listed below to support practitioners, parents and young people to have these conversations, and to assess risk.

Most young people report their suicide attempt did not require medical treatment but it’s not known whether they still engaged with a health care provider post-attempt. Further understanding about young people’s health care engagement is needed, so any barriers can be addressed.
