Background: Reorienting healthcare towards a more person-centred approach requires new approaches to evaluate whether care is perceived as person-centred from the patients’ perspective. The overall aim of this project was to develop a Rasch-analysed item bank to describe and measure patient experiences of person-centred care for people with chronic or long-term conditions. Methods: From a previous review of extant patient-reported experience measures for Person-centred care, items that best probed the University of Gothenburg Centre for Person-Centred Care and the Person-Centred Coordinated Care conceptual models was selected. The candidate items were translated into Swedish before a qualitative item analyse with two validation rounds using questionnaires, a focus group, and individual interviews with different stakeholders. Resulting items (n = 57) were handed out to 140 adults with various cancer diseases in Sweden and to 501 adults with different types of long-term conditions in the United Kingdom. Rasch analyse was used to examine psychometric properties of the candidate items. Results: Out of 855 items, 155 item was translated to Swedish and 111 items was selected for the qualitative analysis. The language used in many of the extant questionnaires was outdated and even inappropriate for the core principles of PCC. The qualitative item analysis resulted in 57 items, rewritten as statements and to position patients as actively partnering in their care. For the initial analysis there were several indicators of misfit such as signs of local dependency. Local dependency could be accommodated for with superitems and/or by removal of items that did not fit the Rasch measurement model. Conclusion: The results support a hierarchical model of patient perceived person-centred care, from items regarding rapport and communication to higher levels with items representing the partnership, shared decisions, and goals. This item set can be used for development of a future item bank.
