Reliability and validity of the Japanese version of the Person-Centered Care Assessment Tool

To evaluate the reliability and validity of the Japanese version of the Person-Centered Care Assessment Tool (P-CAT-J) in a Japanese long-term care setting.

This was a cross-sectional survey using self-administered questionnaires distributed among the nurses or care staff of 2000 special nursing homes randomly selected nationwide using stratified random sampling according to each prefecture's ratio of numbers of facilities. The internal consistency of the tool was calculated using Cronbach's α and construct validity was assessed using confirmatory factor analysis. The criterion-related validity of the scale was based on the partial correlation between the possible outcomes of person-centered care (PCC).

In total, 324 samples were analyzed after excluding samples with incomplete P-CAT-J. Cronbach's α value for the entire P-CAT-J was adequate, although internal consistency values for each factor were not strong. Confirmatory factor analysis revealed an acceptable value after adjusting for error variables. The partial correlation coefficients among workplace satisfaction, quality of care, PCC implementation and total P-CAT-J score were significantly correlated.

The overall P-CAT-J was developed with good reliability and acceptable criteria based on the responses of long-term care staff in Japan. The P-CAT-J has the potential for international comparison and can provide long-term care staff with PCC examples to learn relevant actions and concepts. Geriatr Gerontol Int 2022; 22: 344-349.
