Background: The Children's Palliative Outcome Scale (C-POS) is being developed using best methodological guidance on outcome measure development, This recommends cognitive testing, an established method of item improvement, prior to psychometric testing., Aim: To cognitively test C-POS within the target population to establish comprehensibility, comprehensiveness, relevance and acceptability., Design: Cross-sectional cognitive interview study following COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology and Rothrock guidance on outcome measure development. Cognitive interviews were conducted using 'think aloud' and verbal probing techniques., Setting/participants: Children 5-⩽17 years old with life-limiting conditions and parents/carers of children with life-limiting conditions were recruited from 14 UK sites., Results: Forty-eight individuals participated (36 parents; 12 children) in cognitively testing the five versions of C-POS over two to seven rounds. Content and length were acceptable, and all questions were considered important. Refinements were made to parent/carer versions to be inclusive of non-verbal children such as changing 'share' to 'express' feelings; and 'being able to ask questions' to 'having the appropriate information'. Changes to improve comprehensibility of items such as 'living life to the fullest' were also made. Parents reported that completing an outcome measure can be distressing but this is anticipated and that being asked is important., Conclusion: Cognitive interviewing has facilitated refinement of the C-POS, especially for non-verbal children who represent a large proportion of those with a life-limiting condition. This study has enhanced the face and content validity of the measure and provided preliminary evidence for acceptability for use in routine practice., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The number of children worldwide requiring palliative care services is increasing due to advances in medical care and technology. The use of outcome measures is important to improve the quality and effectiveness of care., Aim: To systematically identify health-related quality-of-life outcome measures that could be used in paediatric palliative care and examine their feasibility of use and psychometric properties., Design: A systematic literature review and analysis of psychometric properties., Data Sources: PsychInfo, Medline and EMBASE were searched from 1 January 1990 to 10 December 2014. Hand searches of the reference list of included studies and relevant reviews were also performed., Results: From 3460 articles, 125 papers were selected for full-text assessment. A total of 41 articles met the eligibility criteria and examined the psychometric properties of 22 health-related quality-of-life measures. Evidence was limited as at least half of the information on psychometric properties per instrument was missing. Measurement error was not analysed in any of the included articles and responsiveness was only analysed in one study. The methodological quality of included studies varied greatly., Conclusion: There is currently no 'ideal' outcome assessment measure for use in paediatric palliative care. The domains of generic health-related quality-of-life measures are not relevant to all children receiving palliative care and some domains within disease-specific measures are only relevant for that specific population. Potential solutions include adapting an existing measure or developing more individualized patient-centred outcome and experience measures. Either way, it is important to continue work on outcome measurement in this field., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2016.)

Background: Development of a paediatric palliative care child and family centred outcome measure is a priority for health care professionals, researchers and advocates. It is methodologically challenging to develop a measure relevant for such a heterogenous population with complex needs. Involving children in measuring development is vital. Objective: To develop C-POS:UK (Children's Palliative Care Outcome Scale, UK), a person-centred outcome measure (PCOM) for children with life-limiting conditions and their families, and to test its psychometric properties. Design: Sequential mixed-methods approach to PCOM development, guided by Rothrock's measure development process and COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) methodology. Methods: (i) Qualitative interviews about priority symptoms and concerns, with embedded exploration of measure design for children with life-limiting conditions; (ii) systematic review of measure design for children; (iii) modified Delphi survey, and consultation with children, on priority items for new measure; (iv) expert item generation meeting to develop C-POS:UK; (v) cognitive testing to refine C-POS:UK; (vi) psychometric validation. Results: (i) 106 participants described physical, emotional/psychological, spiritual/existential, social and practical concerns. Measure design was discussed by 79 participants comprising preferred response format, recall period and measure administration for children with life-limiting conditions; (ii) systematic review highlighted need for: different versions of measure accounting for child's developmental stage and cognitive ability; parent/carer involvement as proxies for very young children; and testing to clarify recall periods and response formats at different developmental stages; (iii) Delphi survey: 82 participants (in the first round), with a move towards consensus, but with some differing priorities in stakeholder groups: professionals prioritised physical symptoms, parents prioritised psychosocial and practical matters, while consulted children prioritised normality; (iv) 22 experts contributed to item generation meeting, resulting in five versions of C-POS:UK accounting for child's developmental stage and cognitive ability, and proxy involvement; (v) 48 participants cognitively tested initial C-POS:UK, informing comprehension, comprehensiveness and acceptability; (vi) psychometric validation is ongoing. Conclusion: A sequential approach informed by Rothrock and COSMIN has supported development of the first version of C-POS:UK. Psychometric validation is underway and will be followed by implementation planning. [ABSTRACT FROM AUTHOR]

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.
