Academic pressure is known to have a detrimental impact on mood and overall wellbeing, but until now few studies had examined the long-term effects on mental health. Researchers at University College London examined data from nearly 5,000 young people born in 1991 and 1992 taking part in a wider ongoing study of children. Academic pressure was assessed at the age of 15 through questionnaires on their school experiences, while mental health was tracked regularly from 16 to 22 and self-harm until they were 24. The study, published in the Lancet Child and Adolescent Health, found that those 15-year-olds who worried most about their school work or felt the most pressure from their families to do well academically were more likely to report higher levels of depression or episodes of self-harm even into early adulthood. They also found that for every extra point of academic pressure reported as 15-year-olds, the likelihood of depression and self-harm by the age of 16 was 25% and 8% higher respectively.
