German translation, cultural adaptation and testing of the Person-centred Practice Inventory - Staff (PCPI-S).

Aim: The aim of this study was to translate and culturally adapt the PCPI-S into German and to eventually test its psychometric properties in long-term care settings.

Background: Person-centred practice has been widely adopted internationally as a best-practice model in nursing and health care. To ensure a sustainable implementation of this practice and to successively promote it, person-centred practice should be evaluated on a regular basis. The Person-centred Practice Inventory-Staff (PCPI-S), which is based on McCormack & McCance's Person-centred Practice Framework, is a new instrument for this purpose by assessing perceptions of person-centredness among healthcare staff.

Design: A two-phase research design was used involving the translation and cultural adaption of the PCPI-S from English to German (PCPI-S-G; Phase 1) and a quantitative cross-sectional survey (Phase 2).

Methods: Construct validity was evaluated using confirmatory factor analysis (CFA), and internal consistency was calculated using Cronbach's α.

Results: Phase 1 was conducted using an internationally recommended checklist for translations and cultural adaptations. In Phase 2, the PCPI-S-G was tested in 15 residential care homes in Austria with a sample of 255 staff members. The CFA showed good construct validity and supported the theoretical framework. The internal consistency for the three constructs of the PCPI-S was excellent, revealing Cronbach's α-scores from 0.902-0.941.
