Background:There is no validated outcome measure for use in children’s palliative care outside sub-Saharan Africa. Stakeholders must be involved in the development of such measures to ensure face and content validity.Aim:To gain expert stakeholder consensus on items for inclusion in a paediatric palliative care outcome measure to establish face and content validity.Design:This study was conducted in two phases following Rothrock and COSMIN guidance on patient-reported outcome measure development. Phase 1: Three-round modified Delphi survey to establish consensus on priority items. Phase 2: Item generation meeting with key stakeholders to develop initial measure versions. A young person’s advisory group was also consulted on priority outcomes.Setting and participants:Delphi survey: Parents and professionals with experience of caring for a child with a life-limiting condition. Young person’s advisory group: young people age 10–20 years. Item generation meeting: bereaved parents, academics and clinicians.Results:Phase 1: Delphi survey (n = 82). Agreement increased from Kendall’s W = 0.17 to W = 0.61, indicating movement towards consensus. Agreement between professional and parent ranking was poor (Cohen’s kappa 0.13). Professionals prioritised physical symptoms, whereas parents prioritised psychosocial and practical concerns. Advisory group: Children (n = 22) prioritised items related to living a ‘normal life’ in addition to items prioritised by adult participants. Phase 2: Five age/developmental stage appropriate child and proxy-reported versions of C-POS, containing 13 items, were drafted.Conclusions:This study highlights the importance and feasibility of involving key stakeholders in PROM item generation, as important differences were found in the priority outcomes identified by children, parents and professionals.
