What is the definition of direct-to-consumer advertising in health communication?

Direct-to-consumer advertising in health communication is best defined as promotional strategies that directly target consumers, enabling them to receive information about health products or services without needing to filter it through a healthcare professional. This type of advertising often encourages consumers to seek and discuss these products with their doctors.

While the option about requiring a doctor's involvement speaks to the interaction that may occur as a result of such advertising, it does not capture the essence of direct-to-consumer advertising, which allows consumers to have direct access to information. The other definitions present do not accurately reflect the central concept of direct engagement with consumers, focusing instead on professionals or the structure of the advertising methods.
