Cross-cultural adaptation and validation of the COPD Patient- Reported Experience Measure (PREM-C9) in Spanish and Catalan.

Abstract

Abstract Patient Reported Experience Measures (PREMS) are questionnaires developed to assess the patient experience(1) and incorporate a vision of patient centered care as a new element of value in the quality of healthcare. The PREM-C9 was developed and tested recently in the UK for patients with chronic obstructive pulmonary disease (CODP). The aim of the current study was to test the validity and reliability of the PREM-C9 in Spanish and Catalan. 289 patients with COPD completed the PREM-C9 (male 71.3%; female 28.7%). Internal consistency was high for both the Spanish [Cronbach’s alpha = 0.812] and Catalan [Cronbach’s alpha = 0.877] versions. Confirmatory Factor Analysis (CFA) proved the item distribution and dimensional structure of the questionnaire except for item2 of the scale “My everyday life with COPD”. Goodness-of-fit indices were very close to acceptable values for the CFI/TLI of 0.90. The three hypotheses tested to assess known groups’ validity were all confirmed. Participants with lower levels of education or with higher levels of breathlessness had poorer scores on the PREM-C9, while respondents reporting higher overall satisfaction with care reported better scores on the questionnaire. Accessibility to healthcare services and breathlessness were important factors in the regression model used to investigate variables affecting PREM-C9 scores accounting for 20% of the variance. This study has provided evidence for good reliability and structural and construct validity of the Catalan and Spanish versions of the PREM-C9.
