A convenience sample of 6124 young people (age 18–22) completed an online survey about their experiences of sport as children (up to age 16); 89 follow-up telephone interviews were conducted. The article provides information about the emotional harm of children in sport and the context within which it occurs. It provides some evidence of a sporting culture where emotional harm is widespread at all levels of sport and commonly experienced by children of all ages.
