A landmark UCL study finds each step up in school pressure increases long-term mental health risks, prompting urgent calls for whole-school reform

Pressure to succeed in school at age 15 is associated with greater rates of depression and a quantifiable increase in self-harm risk far into adulthood, according to new research headed by academics at University College London and published in The Lancet Child and Adolescent Health. 

The study looked at 4,714 young people from the long-running Avon Longitudinal Study of Parents and Children (ALSPAC), also known as the "Children of the 90s" cohort. Researchers investigated how teens felt about academic pressure around the time of their GCSE exams at age 15 and then tracked depressed symptoms from ages 16 to 22, with self-harm measured until age 24. 

The most remarkable discovery is numerical—and stark. “Each one-point increase on a nine-point scale of academic pressure at age 15 was associated with 8% increased odds of self-harm... as late as age 24.” 

Simply put, for every increase in reported pressure—whether from schoolwork, parents, or internal expectations—the statistical risk of self-harm increased by about a tenth. This relationship persisted for over a decade. 

What amount of pressure is too much? 

A certain level of challenge may motivate students to perform better. However, when pressure becomes chronic stress, which is defined as continuing emotional strain without recuperation, it can have an impact on mood, sleep, concentration, and long-term well-being. Teenagers who reported more pressure at 15 had more depression symptoms year after year. 

Senior author Professor Gemma Lewis of UCL Psychiatry stated that the findings are especially troubling given the increased incidence of depression among young people. 

“We found that young people who felt more pressured by schoolwork at age 15 went on to report higher levels of depressive symptoms for multiple years into adulthood.” 

Can exam stress have long-term consequences for mental health? 

Depressive symptoms include continuous melancholy, loss of interest, exhaustion, and problems thinking coherently. The study discovered that academic pressure measured at ages 11 and 14 was associated with subsequent depression symptoms, indicating that early exposure is important. 

However, the researchers emphasised that the study was observational. This means that it identifies relationships rather than direct causes and effects. Academic pressure was quantified using questionnaires that included both external expectations and personal concerns. 

Does academic pressure lead to self-harm? 

The research cannot show that pressure directly causes self-harm. However, the continuous connection, which extends to age 24, suggests that academic contexts may pose a long-term mental health risk. 

Are mindfulness programmes sufficient? 

Recently, schools have incorporated counselling services and mindfulness apps. However, Professor Lewis contends that focusing primarily on assisting individuals in coping may overlook the wider picture. 

“Current approaches... tend to be focused on helping individual pupils cope; we hope to address academic pressure at the whole-school level by addressing the school culture.” 

The researchers recommend decreasing excessive testing, reconsidering assessment intensity, and improving social and emotional learning. 

What changes should schools implement? 

Mind, the mental health charity, welcomed the findings. Tolu Fashina-Ayilara, Senior Policy and Influencing Officer, commented, "UCL's study highlights the significant harm academic pressure can have on young people's mental health." 

The Royal Society and Wellcome financed the study. Researchers point out that participants were 15 in 2006-07, before recent legislative changes and the Covid-19 pandemic. More up-to-date data is required. 

Nonetheless, the message is clear: academic pressure is more than just a personal worry. It is measurable, persistent, and potentially damaging. If each incremental increase in pressure raises long-term risk by 8%, officials may need to approach school culture as a public health environment rather than a performance engine.
