Validation of a modified Russian-language version of the Norwegian “Patient Experience Questionnaire”

To date, there are no specific scales in the Russian Federation for the comprehensive assessment of patient satisfaction and experience of outpatient medical care. Objective. To validate the previously translated Norwegian "Patient Experience Questionnaire" (PEQ), a validated patientreported experience measure (PREM) for outpatients. Materials and methods. Patients aged over 18 years were invited to complete the questionnaire within 24 h after visiting a physician by clicking on a link in the QR [quick response] code printed on the medical report. The construct, discriminant validity, and reliability of individual questions, domains, and the entire questionnaire were analyzed. Results. A total of 452 patients (47.3% male, median age 55 [38–68] years) completed the questionnaire. Less than 18% of the responses were missing. These responses were considered "missing at random". Most patients in this cohort had higher education (67.7%), were married (58%), and were seen by a female physician (91.4%). In confirmatory factor analysis, the factor loadings of the questions were all above 0.6 units, and the reliability of each question, individual scales, and the entire questionnaire was above 0.8 units. The overall questionnaire model met all the goodness-of-fit criteria. Conclusions. The construct and discriminant validity of the previously translated into Russian language Patient Experience Questionnaire, has been confirmed. This PREM is proposed to be used in routine clinical practice and scientific studies under the name "RuPEQ".
