Person-centered care assessment tool with a focus on quality healthcare: a systematic review of psychometric properties

Abstract

Background: The person-centered care (PCC) approach plays a fundamental role in ensuring quality healthcare. The Person-Centered Care Assessment Tool (P-CAT) is one of the shortest and simplest tools currently available for measuring PCC. The objective of this study was to conduct a systematic review of the evidence in validation studies of the P-CAT, taking the “Standards” as a frame of reference. Methods: First, a systematic literature review was conducted following the PRISMA method. Second, a systematic descriptive literature review of validity tests was conducted following the “Standards” framework. The search strategy and information sources were obtained from the Cochrane, Web of Science (WoS), Scopus and PubMed databases. With regard to the eligibility criteria and selection process, a protocol was registered in PROSPERO (CRD42022335866), and articles had to meet criteria for inclusion in the systematic review. Results: A total of seven articles were included. Empirical evidence indicates that these validations offer a high number of sources related to test content, internal structure for dimensionality and internal consistency. A moderate number of sources pertain to internal structure in terms of test-retest reliability and the relationship with other variables. There is little evidence of response processes, internal structure in measurement invariance terms, and test consequences. Discussion: The various validations of the P-CAT are not framed in a structured, valid, theory-based procedural framework like the “Standards” are. This can affect clinical practice because people’s health may depend on it. The findings of this study show that validation studies continue to focus on the types of validity traditionally studied and overlook interpretation of the scores in terms of their intended use.
