The use of Focus Groups for Idea Generation: The Effects of Group Size, Acquaintanceship, and Moderator on Response Quantity and Quality

This is the authors' abstract. We don't add key points for this paper.

Assumptions about focus group interviewing were tested. Individual interviews generated more ideas than focus groups, eight-member groups generated significantly more ideas than four-member groups, no differences were found between focus groups and unmoderated discussion groups, and the effect of acquaintanceship was not clearly determined.
