Exploring how to evaluate a qualitative patient-centered outcome measure: literature review and illustrative example – a Perthes child-friendly measure

摘要

PurposeTo explore the question of ‘how to evaluate a qualitative patient-centred outcome measure’, comprising predominantly open-ended items, including perhaps emojis, story writing and/or pictures, in a way that does not compromise the strictures of the qualitative paradigm, doing so in a credible and authoritative manner. The paper aims to promote debate and discussion in the measurement validation community.
