The Youth Endowment Fund (YEF) surveyed nearly 11,000 children aged 13–17 in England and Wales to hear directly about their experiences of violence. The findings are being shared across several reports, each exploring a different theme. This third report focuses on mental health and experiences of violence. For the first time, we asked detailed questions about mental health, including using the Strengths and Difficulties Questionnaire (SDQ), a 25-item questionnaire that measures the scale of children’s struggles. Combined with data on victimisation and perpetration, this provides an unprecedented picture of how violence and mental health are linked — and the complex ways they shape young people’s lives. Here’s what we found. Teenage children affected by serious violence face a dramatically higher risk of mental health problems. The scale of poor mental health among teenagers is alarming. More than one in four 13-17-year-olds reported high or very high levels of mental health difficulties, as measured by the SDQ — the equivalent of nearly a million teenage children struggling with their well-being. Behind this figure lie serious and often complex needs. A quarter of teenage children reported a diagnosis of at least one mental health or neurodevelopmental condition, such as depression, attention deficit hyperactivity disorder or speech and communication difficulties. A further 21% suspected they had a condition but had not been formally diagnosed — suggesting large numbers of teenage children are facing difficulties without recognition or support
