Children who have parents with any kind of illness may become young carers who take a responsibility not expected of children for household tasks, or personal or emotional care for parents and siblings. So far, little is known about children in Sweden who are at risk of becoming young carers. The aim of this article is therefore to explore the extent and impact of children's caring activities as reported in a pilot study by a sample of children in Sweden. A number of international questionnaires measuring the amount of caring activities, impact of caring, quality of life, and psychological well-being were translated and combined into a survey. The pilot survey was completed by 30 children 10-18 years of age. Also, when completing the survey, the children were interviewed concerning their experiences of caregiving. The participants report on a group level emotional symptoms such as fear and nervousness above the clinical cut-off value. They also rate a lower level of caring compared with findings from the United Kingdom, but they report a higher degree of negative impact of caring than young carers in the United Kingdom.
