Patient-Physician Discordance Scale
Patient–physician discordance is operationally defined as the difference between patient and physician evaluations of health-related information. The Patient–Physician Discordance Scale (PPDS) is an instrument developed and validated to assess discordance between physicians and their patients on evaluations of health-related information. The 10-item questionnaire is designed to be employed across chronic diseases and can be used in clinical practice and research. It measures the extent of patient–physician discordance on five aspects of the patient’s health status and five aspects of the office visit.
