Psychometric evaluation of the Swedish version of the Person-Centered Care Assessment Tool (P-CAT)

Background: Person-centered care is a multidimensional concept describing good care, especially within aged care and care for people with dementia. Research studies evaluating person-centered care interventions seldom use direct measurement of levels of person-centeredness. Existing scales that measure person-centeredness need further testing. This study evaluated the psychometric properties of the Swedish version of the Person-Centered Care Assessment Tool (P-CAT). Methods: A cross-sectional sample of 1465 staff from 195 residential care units for older people in Sweden participated in the study. Validity, reliability, and discrimination ability of the scale were evaluated. Results: Confirmatory factor analysis, parallel analysis and exploratory factor analysis supported the construct validity of a two-factor solution. Reliability and homogeneity were satisfactory for the whole P-CAT as demonstrated by a Cronbach's α of 0.75. Test-retest reliability showed temporal stability of the scale, and the discrimination ability of the scale was satisfactory. Conclusion: The Swedish version of the P-CAT was found to be valid, reliable, and applicable for further use. Two subscales are recommended for the Swedish version
