INTRODUCTION: Person-centred care is widely recognised as the gold standard of quality in terms of gerontological care approaches and offers an alternative to traditional, medically oriented models. The Person-Centered Care Assessment Tool (P-CAT), developed by Edvardsson et al. (2010), is one of the most extensively studied instruments for adaptation and validation across countries. However, its structural invariance remains questionable, with the number of factors varying from one to three depending on the study. Currently, no validated French version exists. This study aims to explore the psychometric properties of the French version of the P-CAT among nursing home staff. METHODS: We translated the P-CAT into French. A total of 473 participants, recruited in 41 nursing homes and divided into two independent samples, completed several questionnaires including the P-CAT. We conducted exploratory and confirmatory factor analyses and assessed reliability, as well as convergent and divergent validity of the P-CAT. RESULTS: Exploratory and confirmatory factor analyses supported a three-factor structure with adequate internal consistency (ω = 0.79). The three dimensions are related to the following: Organisational and environmental support
care planning
and adaptability to the residents' needs. Good convergent validity and divergent validity were documented. CONCLUSION: The French version of the P-CAT demonstrated good psychometric properties and a structural invariance among nursing home staff. It can be used in research and practice to assess person-centredness in gerontological care settings.
