Final answer:
In interviews, the amount of conversation controlled by the health professional can vary depending on the interview style. Informal interviews give more control to the participant, while highly structured interviews allow the health professional to gather specific information.
Step-by-step explanation:
In interviews, the amount of conversation controlled by the health professional can vary depending on the interview style. In informal interviews, the health professional gives the participant more control over the conversation. This allows for a more relaxed atmosphere and may result in the participant feeling more comfortable sharing information. On the other hand, in highly structured interviews like illness narrative interviews, the health professional has more control over the conversation to gather specific information about the person's illness experience.
