The motivations and methods behind sharing a pediatric Prader–Willi syndrome diagnosis

Abstract

AbstractPrader–Willi syndrome (PWS) is a genetic condition caused by a lack of paternally‐expressed imprinted genes at chromosome 15q11.2‐q13 and characterized by hyperphagia, behavioral challenges, and variable intellectual disability. Once a PWS diagnosis is established, sharing diagnosis information with an affected child can be challenging due to its early age of onset and diverse phenotype. This mixed‐methods study aimed to evaluate how parents and guardians have shared a PWS diagnosis with their child and examine the motivating and influencing factors behind their disclosure. Parents and guardians of children with PWS aged at least 5 years completed a survey, and a select group completed an interview. A total of 51 surveys and 15 interviews were completed, with the majority of participants (n = 46; 90%) having shared at least some diagnosis information with their child. Parents and guardians were more likely to disclose if they self‐reported a higher level of knowledge about PWS (p = 0.004) and if their child is currently older (p = 0.02) and/or has at least one sibling (p = 0.046). Interview analysis revealed 15 themes and 10 subthemes that illustrated parents' motivations, methods, and experiences with disclosure. This research provides information for others considering disclosure of PWS or another rare diagnosis with their child.
