The Swedish P-CAT: modification and exploration of psychometric properties of two different versions

Research output: Contribution to journalArticle

Abstract

The aim of this study was to further investigate the psychometric properties (with focus on construct validity and scale function) of the Swedish version of the Person-centred Care Assessment Tool (P-CAT) in a sample consisting of staff working in elderly care units (N = 142). The aim was also to further develop and psychometrically test a modified, noncontext-specific version of the instrument (mP-CAT) in a sample consisting of staff working in primary health care or within home care for older people (N = 182). Principal component analysis with varimax rotation initially suggested a three-factor solution for the P-CAT, explaining 55.96% of variance. Item 13 solely represented one factor wherefore this solution was rejected. A final 2-factor solution, without item 13, had a cumulative explained variance of 50.03%. All communalities were satisfactory (>0.3), and alpha values for both first factor (items 1-6, 11) and second factor (items 7-10, 12) were found to be acceptable. Principal component analysis with varimax rotation suggested a final 2-factor solution for the mP-CAT explaining 46.15% of the total variance with communalities ranging from 0.263 to 0.712. Cronbach's alpha for both factors was found to be acceptable (>0.7). This study suggests a 2-factor structure for the P-CAT and an exclusion of item 13. The results indicated that the modified noncontext-specific version, mP-CAT, seems to be a valid measure. Further psychometric testing of the mP-CAT is however needed in order to establish the instrument's validity and reliability in various contexts.
