The doctor–patient relationship is one factor in determining the patient's compliance with medical advice.[3] Patients adhere more closely to medical advice when the healthcare provider is friendly, doesn't interrupt the patient, or has good verbal communication skills.[4] Patients are less likely to comply with medical advice if the advice is not what the patients expected, if the patients do not agree with the proposed treatment, if the patient is not confident in the provider's competence, or if the patient cannot understand what the provider says due to language barriers or overuse of medical jargon. Patients are also less likely to comply with medical advice if the healthcare provider seems disrespectful of the patient or appears to hold negative stereotypes of the patients' race, class, or other characteristics.[5][3]
