How do researchers ensure confidentiality among focus group participants?

A) Legal recourse through confidentiality agreements
B) Honor system and confidentiality agreements
C) Handshakes between participants
D) Fear of participant and researcher retaliation

Researchers typically ensure confidentiality among focus group participants through the use of confidentiality agreements, which all participants must sign. However, the ultimate responsibility for maintaining confidentiality rests with the participants themselves, who must make a good faith effort to keep the discussions confidential. Handshakes or fear of retaliation are not effective methods for ensuring confidentiality.
