Different researchers have their own concerns and research orientations, and ultimately there is no unified answer, but for any health communication problem, a single research orientation will be insufficient.
Nine research directions:
Research on Mass Health Media and Its Effect
Organizational health communication research
Research on interpersonal health communication centered on "doctor-patient relationship"
Research on Health Education and Health Promotion
Study on the External Environment of Health Communication
Health communication and cultural studies
Special research on AIDS, euthanasia, homosexuality and organ transplantation.
A Historical Study of Health Communication
Sudden public health events (study on the spread of health crisis)
