Factor 1: Whether medicine is considered omnipotent
This set of questions all reflects the level of belief in biomedical technology
Factor 2: Whether the patients are recognized as competent
This set of questions all reflects attitudes towards the patient’s ability to play an active role in treatment
Factor 3: How to view doctors’ interpersonal style
This set of questions all reflects the cognitive attitude of doctors in addition to medical treatment, such as the doctor’s personality traits and communication style
Factor 4: Whether recognition of patients’ feelings affects patients’ medical behaviour and outcome
This group of questions reflects the importance of the patient’s feelings during the treatment process
