The aim of this study was to describe discursively constructed interactions between parents and health care professionals (HCPs) in a pediatric oncology ward. Field notes from 70 focused participant observations and 16 informal interviews with 25 HCPs interacting with 25 parents of children with cancer were analyzed using discursive psychology. Six dominant interpretative repertoires (flexible parts of discourses used in everyday interaction) were found. Repertoires used by the HCPs were child, parent, or family oriented, mirroring the primary focus of the interaction. Parents used a spokesperson repertoire to use their own expertise to talk on behalf of the child; an observer repertoire, in which they kept in the background and interfered only when needed; or a family member repertoire to position themselves on a level equal to the ill child. The results are discussed in relation to philosophies influencing pediatric nursing, such as family-centered nursing and child-centered nursing.
