One in five students who think about suicide will attempt it during university
A sweeping international study of nearly 73,000 university students has surfaced a quiet crisis unfolding at the threshold of adulthood: nearly half of young people entering higher education have contemplated ending their lives, and transgender students face risks so elevated they constitute a distinct emergency within the emergency. Conducted across 18 countries by researchers at the Hospital del Mar Research Institute, the study reminds us that the passage from adolescence to university is not merely academic — it is, for many, a passage through profound psychological peril. The findings call not for alarm alone, but for the kind of sustained, structural attention that has long been owed to the mental lives of the young.
- Nearly half of all first-year university students have experienced suicidal ideation at some point in their lives — a figure that reframes campus mental health as a systemic crisis, not an individual failing.
- Transgender students face a 3.6 times higher likelihood of attempting suicide than their cisgender peers, a disparity that persists even after researchers account for mental illness and childhood trauma — pointing directly to the weight of harassment and social stigma.
- The critical danger zone is the twelve-month window surrounding university entry, when 30% of students report suicidal thoughts and 2.3% make an attempt, making early screening not a luxury but a clinical imperative.
- Childhood sexual abuse, bipolar disorder, and panic disorder emerged as the strongest predictors of the leap from thought to action — offering researchers a clearer map of who is most urgently at risk.
- The study's authors are pushing for universal screening beginning in adolescence and the expansion of online therapy options, recognizing that stigma, distance, and scheduling keep many students from ever reaching a counselor's door.
Researchers at the Hospital del Mar Research Institute have completed one of the largest studies of its kind, surveying nearly 73,000 first-year students across 71 universities in 18 countries. What they found was a landscape of quiet suffering: nearly half of all university students have contemplated suicide at some point, a quarter have made a plan, and one in ten have attempted it.
The year immediately surrounding university entry proved to be the most dangerous window. In that twelve-month period, nearly a third of students reported suicidal thoughts, and more than two percent had made an attempt. Led by Dr. Philippe Mortier, the research team designed their questionnaire specifically to trace the pathway from thought to planning to action — a distinction they found essential to identifying who is most at risk of crossing the line from contemplation to crisis.
Among the strongest predictors of that crossing: childhood sexual abuse, bipolar disorder, and panic disorder. But the finding that most surprised the team involved transgender students, whose elevated risk held firm even after accounting for mental illness and prior trauma. Compared to cisgender peers, transgender students were 2.4 times more likely to experience suicidal ideation and 3.6 times more likely to attempt suicide — a disparity the researchers link substantially to experiences of harassment and discrimination.
Mortier argues that the space between ideation and action is precisely where prevention becomes possible. While nearly half of students will think about suicide, only a fraction will move toward planning or attempting — and identifying that smaller group early is where resources should be concentrated. The study calls for universal screening beginning in adolescence, expanded campus mental health services, and online therapy options capable of reaching students who might never seek in-person care. The window is narrow, the researchers note, but it is real.
Researchers at the Hospital del Mar Research Institute have completed one of the largest international studies of mental health among university students, surveying nearly 73,000 first-year students across 71 universities in 18 countries. The findings paint a sobering picture of psychological distress during a critical life transition: nearly half of all university students have contemplated suicide at some point, a quarter have planned it, and one in ten have attempted it.
The vulnerability is sharpest in the year immediately before the survey. In that twelve-month window, 30 percent of students reported suicidal thoughts, 14 percent had developed a plan, and 2.3 percent had made an attempt. The researchers, led by Dr. Philippe Mortier, designed the questionnaire to capture not just whether students had experienced suicidal ideation, but to trace the pathway from thought to planning to action—a distinction that proved crucial to understanding who is at greatest risk.
The study identified several factors that push students from thinking about suicide to actually attempting it. Childhood trauma emerged as a significant predictor, particularly emotional abuse. But the researchers were struck by the outsized role of bipolar disorder and panic disorder in predicting the transition to actual attempts. Sexual abuse in childhood also appeared as a major risk factor. These three elements—sexual abuse, bipolar disorder, and panic disorder—stood out as the strongest predictors of whether someone would move from contemplation to action.
One finding surprised the research team: transgender students face dramatically elevated risk even after accounting for mental illness and childhood trauma. These students are 2.4 times more likely to experience suicidal thoughts and 3.6 times more likely to attempt suicide compared to their cisgender peers. The researchers attribute this disparity partly to experiences of harassment and discrimination, suggesting that the additional burden of social stigma compounds the already significant mental health challenges of the university transition.
Mortier emphasizes that the distinction between ideation and action is where intervention becomes possible and necessary. While nearly half of university students will think about suicide at some point, only a fraction will move to planning or attempting. Identifying that smaller, higher-risk group early is where prevention efforts should concentrate. The study recommends universal screening for suicidal ideation beginning in adolescence and continuing through the university years, when one in five people who have thought about suicide will make an attempt.
The researchers also point toward practical next steps: expanding access to mental health services on campus, and piloting online therapy that students could pursue independently or with remote professional support. Such approaches could reach students who might otherwise avoid in-person care due to stigma, distance, or scheduling barriers. The window for intervention is narrow but real—catching someone in the gap between thought and action could mean the difference between a crisis managed and a life lost.

The Hearth Conversation Another angle on the story
Why does the transition to university seem to amplify suicide risk so sharply?
The study doesn't fully explain the mechanism, but the researchers point to the obvious stressors—academic pressure, social upheaval, separation from home. But there's something else: this is also when many mental illnesses first emerge. The brain is still developing. You're 18, 19, 20, and suddenly you're away from your support system, managing your own life, and possibly experiencing the onset of bipolar disorder or panic for the first time.
The numbers for transgender students are striking—3.6 times higher attempt risk. Is that because they have more underlying mental illness, or something else?
The researchers controlled for that. They adjusted for mental disorders and childhood trauma, and the elevated risk remained. So it's not just that trans students have more bipolar disorder. It's the additional weight of discrimination, harassment, social rejection. It's a burden on top of a burden.
If nearly half of students think about suicide, why do only 10 percent attempt it?
That's actually the most important question the study raises. Most people who think about suicide don't act on it. But some do. The study identified the factors that predict that transition—sexual abuse, bipolar disorder, panic disorder. If you can screen for those, you can focus your resources on the people most likely to move from thought to action.
Online therapy seems like a band-aid for a structural problem.
Maybe. But it's also pragmatic. A lot of students won't seek help in person—shame, stigma, logistics. If you can meet them where they are, even digitally, you catch some who would otherwise fall through. It's not a solution, but it's a tool.
What does the study suggest about prevention in high school, before university?
The researchers are clear that screening should start in adolescence, not wait until students arrive on campus. Suicidal ideation often begins in the teenage years. If you can identify and support kids then, you might prevent the crisis from deepening when they hit the university transition.
