When is important for the focus group moderator to involve themselves in the discussion?

A focus group moderator should involve themselves in the discussion when it's necessary to clarify questions, ensure all participants have a chance to speak, or steer the conversation back on track if it veers off-topic. Additionally, if there's a lack of engagement or dominant voices overshadowing others, the moderator can intervene to foster a more balanced dialogue. Their role is to facilitate a productive environment while still allowing participants to express their thoughts freely.
