“Focus group interviews are conducted to discuLss a specific topic in group sessions. Participants discuss ideas, issues, insights, and experiences among themselves, and each member is free to commaent, criticize, or elaborate on the views expressed by other. The premise underlying the focus group method is that free discussions generate fresh ideas and insights because the participants stimulate each other. Focus groups are limited in size to 8 to 12 carefully-selected participants.”
