Background: The Staff version of the Person-centred Practice Inventory (PCPI-S) has been translated and adopted globally as a leading measure of person-centred practice (Slater et al, 2017). This 56-item questionnaire is theoretically based on the Person-centred Practice Framework by McCormack and McCance (2017) and has been tested and translated in German, French, Norwegian, Spanish, Malaysian, Swedish, Portuguese and Chinese (PCPI-ICoP, 2023). Given the vitality of this instrument in evaluating the development of person-centred practice cultures, there is a growing need to create a short form of the questionnaire. This study aims to develop and psychometrically test the PCPI-S short form, a shorter version of the more comprehensive PCPI-S. There are several advantages – (i) shorter form is time efficient, (ii) it provides a balance between cognitive fatigue and a need to capture all the relevant constructs and domains of the PCP framework, (iii) it also expands on the original PCPI-S by addressing the order effect and by expanding the current rating scale from a 5-point scale to a 7-point scale. Materials and Methods: Completely anonymised secondary data will be obtained from authors of published studies using PCPI-S. A collective global dataset will be collected and organised in clusters of languages and psychometric testing will be performed on this dataset. Through a recursive statistical and expert knowledge exchange process, items are reduced to obtain the short form of the PCPI-S. Results: It is expected in the present study that several items will demonstrate statistical expendability and will be likely candidates for removal. It is also expected that data clusters from other languages will highlight similar items. At the time of submitting this abstract, the study was commencing as planned. It will be complete by the time of the conference, and we will use this opportunity to present a final short form for the first time.
