Validation of the Dutch version of the primary care resources and support for self-management tool: A tool to assess the quality of self-management support.

Abstract

Enhancing the self-management activities of patients improves the quality of care and is an integrated element of current healthcare provision. However, self-management support (SMS) is not yet common in healthcare. The Primary Care Resources and Support for Self-Management (PCRS) is a tool for healthcare professionals to assess the quality of SMS. In this study, we assessed the validity and reliability of the Dutch version of the PCRS. The validation of the PCRS was performed in Dutch healthcare centres. Correlations between the PCRS scores and the Assessment of Chronic Illness Care (ACIC) and Clinician Support for Patient Activation Measure (CS-PAM) scores were calculated to assess the convergent and discriminant validity. A confirmatory factor analysis (CFA) was performed to test the factor structure. Lastly, the internal consistency and face validity were assessed. The convergent and discriminant validity were good, with respective correlations of 0.730 (p < 0.001) and 0.030 (p > 0.050) between the PCRS and the ACIC SMS subscale and the PCRS and the CS-PAM. Although 49% of the variance of the PCRS was explained by one factor, the CFA could not confirm a fit between a one-factor model and the data. The reliability was excellent (Cronbach's α = 0.921). The PCRS showed good validity and excellent internal consistency. However, the evidence for its validity was inconclusive. We therefore suggest rephrasing specific items.
