Abstract
Research with childhood cancer has progressed greatly in recent years, resulting in much improved treatment that is more intensive. However, with this new treatment children often experience negative symptoms, and research shows that nausea is a symptom that most affects them. Pictorial support in person-centred care for children (PicPecc) is a digital picture-based tool for children who undergo treatment due to their cancer diagnosis and helps them more effectively communicate and self-report their symptoms and emotions. The aim of the study was to investigate children's experience of (i) using mHealth in nausea management and (ii) their acceptability of using an application (App). Semi-structured interviews were conducted with eight children aged five to fifteen years. Data were analysed with qualitative content analysis. The findings were presented in three categories: 1) Communicating feelings, 2) Playfulness generated in motivation and 3) App adaptable to children's capabilities. Using an App contributed to new opportunities for the children to participate in their care. They experienced their treatment in different ways and used different strategies to manage and distract themselves from their symptoms. Using the PicPecc App can increase healthcare staff's understanding of how children experience nausea when they undergo chemotherapy.
