In 2018, five articles were published pertaining to the focus group method. Two of these articles discuss the key differentiating attribute of focus groups, i.e., participant interaction and engagement, and the important role this attribute plays in the integrity of the research.
The interactive component of the focus group method also raises questions concerning mode, which is the subject of two other articles in this compilation. Specifically, these articles address the strengths and limitations of the in-person and online asynchronous focus group modes.
The fifth article in this paper discusses the concept of saturation in the context of determining the “right” number of focus groups to conduct for a particular study. Saturation has been discussed before in RDR, with the emphasis being on the idea that saturation alone is an inadequate measure by which to derive the number of events and, in fact, as a sole measure, saturation jeopardizes data quality, see “Designing a Quality In-depth Interview Study: How Many Interviews Are Enough?”
Beyond discussion guide development and the effects of the moderator, there is another critical component that threatens the quality of data gathered in the focus group discussion method: the participants themselves. The participants in a group discussion face a more daunting social environment than in-depth interviewees, an environment in which participants are typically expected to meet (in-person, on the phone, or online) and engage with a group of strangers. At the minimum, participants in a dyad find themselves among two other individuals they have never met (the moderator and other participant); and, in the opposite extreme, participants in an online asynchronous group may be one of 10 or 12 or more people who have been asked to join the discussion.
As with the in-depth interview (IDI) method, focus group participants in any mode (i.e., in-person, phone, or online) may threaten the integrity and credibility of group discussion data by their unwillingness or reluctance to divulge certain information, leading them to say nothing or to make an inaccurate statement. For instance, in some focus group studies, what people do not know (or have not done) is a central part of what the study is exploring (e.g., recruiting people who have not been involved with a local nonprofit organization to learn about their Read Full Text
