Psychometric validation of the Spanish version of the Patient-Doctor Relationship Questionnaire (PDRQ)

Abstract

Introduction: The main aim of this study was to make a Spanish adaption of the international Patient-Doctor Relationship Questionnaire (PDRQ) that assesses the quality of patient-doctor relationship in Spanish patients admitted to an Internal Medicine Service under conditions of regular clinical practice.

Method: A total of 188 adult patients of 6 Internal Medicine physicians from a University Hospital in downtown Madrid were analyzed. Sociodemographic and clinical variables were collected and the PDRQ Spanish version questionnaire was administered.

Results: Results showed excellent psychometric data on reliability, factorial, and construct validity. Furthermore, based on scientific literature, criteria validity was determined, considering continuity of care as external criteria. Results ratify previous data related to positive relation between quality of doctor-patient relation and continuity of care.

Conclusions: The Spanish 13 item version of the PDRQ (CREM-P in Spanish) proved to be a valid instrument for assessing the quality of patient-doctor relation in adult patients, with clinical and research value.
