Cross-Cultural Adaptation and Validation of the Perception of the Doctor-Patient Relationship (PREMEPA) Questionnaire in Chronic Multi-Pathological Patients.

ABSTRACT

OBJECTIVE: To conduct a cross-cultural adaptation and validation in Primary Care of the PREMEPA doctor-patient relationship perception questionnaire. DESIGN: Descriptive, cross-sectional study, using self-administered questionnaires. Qualitative validation an adapted version of the original questionnaire, was adapted to our culture. The process consisted of the evaluation, cross-cultural adaptation and consensus of a group of experts. The questionnaire was piloted on a sample of 32 patients diagnosed with at least 2 chronic pathologies. MEASURES: Cognitive piloting, comprehensibility assessment, content validation and internal consistency analysis using Cronbach's alpha coefficient. Quantitative validation the internal consistency, construct validity and validity of the questionnaire were studied by means of a confirmatory factor analysis developed in a multicenter study, randomly selecting 202 patients with at least 2 chronic pathologies. RESULTS: Content validity of the new Spanish version was confirmed to be adequate. Comprehensibility and internal consistency (Cronbach's α coefficient = 0.78) were adequate. The confirmatory factor analysis showed good dimensionality, factor relationship and internal consistency, as well as acceptable construct validity. The final result was a 13-item questionnaire consisting of 2 dimensions, which explain 58.5% of the variance participation in decision-making (accounting for 45.2% of the variance) and person-centered communication (encompassing courtesy, empathy, humanity, and trust). CONCLUSIONS: This adapted version of the PREMEPA questionnaire can be considered valid for use in the Spanish population with a history of chronic pathology. This version of PREMEPA provides a new instrument to understand and improve chronic patient care, which can improve the doctor-patient relationship, encouraging adherence to treatment and enhancing health outcomes.
