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

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.
