Content Validity of a Patient-Reported Experience Measure (CQRA-PREM) for Patients with Rheumatoid Arthritis in Portugal.

Background: The evaluation of perceptions of patients with rheumatoid arthritis (RA) has a positive influence in their health outcomes and overall experience of care. The Commissioning for Quality in Rheumatoid Arthritis Patient-Reported Experience Measure (CQRA-PREM) was developed to provide the perceptions and the feedback of the patients with RA to the health professionals team. This PREM is already validated and in use in the United Kingdom (UK) and Netherlands. In Portugal, there is no validated PREM to evaluate the experience of patients with RA. Objective: To translate, cultural adapt and validate the content of the CQRA-PREM for the Portuguese population. Methods: A qualitative study using focus groups was conducted to evaluate CQRA-PREM content validity. The CQRA-PREM was first translated and cultural adapted to Portuguese by two researchers, and after back translation, a panel of experts agreed on the preliminary Portuguese version of CQRA-PREM. Patients with RA were recruited from a rheumatology center at a tertiary university hospital center to participate in focus group meetings. Before the focus group they filled in the preliminary version of CQRA-PREM, with its 7 domains and 24 items (Likert scale 1-5). Results: Twelve participants (median 54 (45-58) years old; 92% female) were included in two focus groups. All domains of the questionnaire had medians of 3 or above. Seven major themes and six subthemes emerged. Participants considered the questionnaire as very clear and simple and with adequate questions. Patients pointed as extremely important being treated with dignity and respect and considered the awareness of the multidisciplinary team and the presentation of support programs and organizations as areas for improvement. Conclusion: The Portuguese version of the CQRA-PREM is acceptable and its content is valid in the perspective of patients with RA to assess the quality of care provided by the healthcare services.
