 Doctors tend to be more agreeable, conscientious, extroverted, and less neurotic than both the general population and patients. Patients, however, tend to be more open than doctors.

These findings suggest that understanding the personality differences between doctors and patients could help improve patient-doctor relationships and increase patient adherence to treatment plans.
