Researchers developed a fast, computerized screening test to identify youth at risk for attempting suicide, the test could help emergency departments quickly get supportive services to those who need it.

Suicide rates for adolescents have risen over the past two decades. In 2019, nearly 1,600 adolescents between the ages of 12 and 17 died by suicide. Only about 40% of adolescents who die by suicide have been treated for a mental health concern. To help ensure that at-risk youth receive help, it is important to screen broadly for suicide risk.

Emergency departments are a common place where youth access emergency care. This makes it is an optimal place to implement universal screening for suicide risk. But emergency rooms face many challenges to screening, including lack of time and budgetary restrictions. A tool that could quickly and accurately identify suicide risk would help providers implement universal screening in these settings.

A team of scientists led by Dr. Cheryl A. King at the University of Michigan, Ann Arbor developed a computerized suicide screener. The screener, called the computerized adaptive screen for suicidal youth (CASSY), asks a series of questions—11 on average—and takes between 1 to 2 minutes to complete.

In collaboration with emergency departments across the U.S., the team recruited youth between the ages of 12 and 17 to help develop and test the screener. The study was funded in part by NIH’S National Institute of Mental Health (NIMH). Results were published on February 3, 2021, in JAMA Psychiatry.

In the first phase of the study, youth who were admitted to an emergency department at the study sites were randomly selected to complete self-report questionnaires (92 main questions and up to 27 additional questions). More than 2,000 youth answered questions on a computer tablet. Questions assessed factors related to suicide risk, including suicidal thoughts; history of suicide attempts; self-injury; depression; hopelessness; alcohol and drug misuse; family, school, and social connectedness; and physical and sexual abuse.

The youth and their parents then received follow-up calls three months after this initial screening to learn if the youth had tried to end their life in the intervening months. The researchers used these data to create the CASSY. They found that using 11 items from the questionnaires could provide nearly the same predictive value as 72 of the questions.

In the second phase of the study, the team tested the ability of CASSY to predict suicide risk in a new set of more than 2,700 youth, aged 12 to17, at 15 emergency departments. Youth completed the CASSY. Similar to phase 1, families were contacted three months later to learn whether the youth had tried to end their life.

In this second phase of the study, 6% of participants attempted suicide in the three months between initial screening and follow-up. CASSY correctly identified 82% of the youth who had attempted suicide.

“No young person should die by suicide, which is why we have made bending the curve in suicide rates a priority area of research for our institute,” says Dr. Joshua A. Gordon, director of NIMH. “The CASSY screener represents an important advance in identifying those adolescents who are at risk for suicide, so they can be connected with the critical support services they need.”

Teen Suicide: Understanding the Risk and Getting Help

Teenagers have their whole lives ahead of them, they’re often told. The idea that a teen could be thinking about ending that life might be hard for their friends, families, or other people in their community to believe.

But the risk of suicide should be on the radar of anyone who interacts with teens, says Dr. Jane Pearson, a mental health expert at NIH.

The rate of teen suicide has increased over the last decade. Suicide is now the second leading cause of death for teens and young adults in the United States.

Experts don’t know why this rate has been rising. But NIH-funded researchers are working on better ways to find and help teens who are thinking of suicide.

“There are some very effective treatments for youth who are suicidal,” Pearson explains. “We’re trying to figure out how to make those treatments more accessible for more youth.”

Who’s at Risk?

Many things can increase the risk of suicide in teenagers. One major risk factor is experiencing a mental health issue like depression, anxiety, or trauma. Most people who die by suicide have struggled with a mental health condition.

Other risk factors include a family history of suicide, violence, or substance abuse. Teens also experience many stressful life events for the first time. These can include a breakup with a romantic partner, trouble at school, violence, or conflicts with friends.

“Teens don’t have the life experience to know that these things will be temporary, that they’ll get through it,” Pearson says. And they might think they’d rather be dead than feel the way they do at that moment in time, she adds.

Persistent misunderstandings about suicide can also keep teens from getting the help they need, adds Pearson.

“Many people think that a teen talking about or attempting suicide are so-called gestures, or cries for attention,” Pearson explains. They don’t think that the teen is in real danger.

“That’s definitely a myth,” says Dr. Cheryl King, a suicide-prevention researcher at the University of Michigan. “If someone has been repeatedly suicidal or talking about it for a long time, that should have us more concerned rather than less concerned.”

Knowing When Teens Need Help

Some of the warning signs that a teen is thinking about suicide are talking about wanting to die, feeling hopeless, or being trapped or in unbearable pain (see the Wise Choices box for more signs).

If you are concerned about a teen who may be thinking about suicide, start a conversation, says Dr. Joan Asarnow, a suicide-prevention researcher and clinical psychologist at the University of California, Los Angeles.

“A conversation can just start with ‘are you OK?’ or ‘is there something that feels like it’s too big of a problem?’” Asarnow explains.

Pearson recommends that people start these conversations early, when they first start to feel that something’s wrong with a teen. “It’s going to be easier to help somebody before they’ve really decided on a course of action to kill themselves,” she says.

But many teens have suicidal thoughts that go unrecognized. King and other NIH-funded researchers are studying ways to better identify teens at risk of suicide.

King is testing a new method to screen teens who come into hospital emergency rooms for suicide risk. While most teens don’t see a mental health specialist, she says, “roughly 1 in 5 goes to the emergency department at least once a year. So, it’s a particularly good place for suicide-risk screening.”

This is especially true because risk-taking behaviors such as substance abuse and dangerous driving can land teens in the emergency room, King explains. And teens who engage in such behaviors are at higher risk of suicide.

Other researchers are looking at ways to use technology to identify when teens already known to be at risk of suicide are most vulnerable. For example, one team is testing whether smartwatches can detect when teens’ emotions are affecting their body before the teens themselves feel distressed.

“New technologies may provide us with a way to intervene at the moment where the kids really need it, without depending on them to reach out on their own,” Asarnow explains.

Keeping Teens Safe

Treatments are available that can help teens at risk of suicide. “Underlying mental health issues like depression and trauma are treatable conditions, and there are ways we can help youths with these troubles once we know about them,” says King. Talk therapy and medications can both be effective for many people.

NIH-funded researchers have also developed therapies that can help very high-risk teens—those who have already attempted suicide, sometimes more than once.

Asarnow and her colleagues recently showed that types of intensive counseling for teens and their families can reduce the risk of another suicide attempt by about a third. This counseling, based on treatments called cognitive-behavioral therapy (CBT) and dialectical behavior therapy (DBT), teaches coping strategies and life skills.

Involving the family in suicide prevention seems to be more effective than just treating the teen, Asarnow says. Her program counsels and teaches parents as well as the teens in their care.

One thing any family can do to help protect a teen thinking of suicide is to talk with a health care provider about putting together a safety plan, she adds. A safety plan is a document the teen and trusted adults create together. It includes coping strategies and contact information for people who have agreed to help in times of crisis.

A safety plan also includes commitments from the family to keeping the teen’s environment safe, such as limiting access to medications and firearms.

The decision to harm oneself is often made in a split second. A safety plan “makes the best decisions the easy things to do,” Pearson explains. “The family wants that, and the teen wants that.”

The more warning signs, the greater the risk of suicide.

  • Talking about wanting to die
  • Looking for ways to kill oneself
  • Talking about feeling hopeless or having no purpose
  • Talking about feeling trapped or in unbearable pain
