What is a limitation regarding confidentiality in focus groups?

The reasoning behind selecting that particular answer is rooted in the nature of focus groups and the dynamics of group interactions. In a focus group setting, participants are encouraged to share their thoughts and experiences openly to generate rich qualitative data. However, once participants leave the group, the researcher has no authority or means to enforce confidentiality agreements. Therefore, they cannot control what individual participants choose to share about the discussions with others outside the group. This reality presents a challenge in ensuring that sensitive information remains confidential, as participants may inadvertently or deliberately disclose details that were meant to remain within the confines of the focus group.

In the context of the other choices, guaranteeing absolute secrecy is impractical and often unrealistic, since complete confidentiality cannot be assured when people are involved. Participants' ability to discuss what occurs within the group also complicates confidentiality. While researchers may request that participants refrain from discussing group content outside of the setting, ultimately it is a guideline rather than a rule that can be enforced. Anonymity among participants within the group is typically maintained, as the focus group's structure allows individuals to interact without knowing each other outside of that context, but this does not address the broader issue of what occurs after the session concludes.
