A long-term health condition (LTHC) affects everyday life for most children and can lead to negative effects on these children’s perception of life and on their health and well-being. When healthcare professionals use a person-centered approach, it makes it easier for them to support children with their individual needs. This can be applied in digital and in person support in health care, but knowledge is scarce about what type of support children would prefer. The aim of this study was first to describe how children with a LTHC experienced digital and in person support as part of their care, second, what type of information they needed and to what extent they considered themselves to be participants in their own care. Twelve children between 10 and 17 years old participated in the study. A qualitative descriptive method was used, with children interviewed either individually or together with a caregiver, with qualitative manifest content analysis. Two categories emerged from the analysis, “Support and involvement in one’s own health care” and “Receiving information in different ways”. Children with a LTHC need information and support that focuses on their own needs. This type of support must be based on both professional and peer-to-peer support.
