Chapter 12. Focus Groups
Introduction
Focus groups are a particular and special form of interviewing in which the interview asks focused questions of a group of persons, optimally between five and eight. This group can be close friends, family members, or complete strangers. They can have a lot in common or nothing in common. Unlike one-on-one interviews, which can probe deeply, focus group questions are narrowly tailored (“focused”) to a particular topic and issue and, with notable exceptions, operate at the shallow end of inquiry. For example, market researchers use focus groups to find out why groups of people choose one brand of product over another. Because focus groups are often used for commercial purposes, they sometimes have a bit of a stigma among researchers. This is unfortunate, as the focus group is a helpful addition to the qualitative researcher’s toolkit. Focus groups explicitly use group interaction to assist in the data collection. They are particularly useful as supplements to one-on-one interviews or in data triangulation. They are sometimes used to initiate areas of inquiry for later data collection methods. This chapter describes the main forms of focus groups, lays out some key differences among those forms, and provides guidance on how to manage focus group interviews.
Focus Groups: What Are They and When to Use Them
As interviews, focus groups can be helpfully distinguished from one-on-one interviews. The purpose of conducting a focus group is not to expand the number of people one interviews: the focus group is a different entity entirely. The focus is on the group and its interactions and evaluations rather than on the individuals in that group. If you want to know how individuals understand their lives and their individual experiences, it is best to ask them individually. If you want to find out how a group forms a collective opinion about something (whether a product or an event or an experience), then conducting a focus group is preferable. The power of focus groups resides in their being both focused and oriented to the group. They are best used when you are interested in the shared meanings of a group or how people discuss a topic publicly or when you want to observe the social formation of evaluations. The interaction of the group members is an asset in this method of data collection. If your questions would not benefit from group interaction, this is a good indicator that you should probably use individual interviews (chapter 11). Avoid using focus groups when you are interested in personal information or strive to uncover deeply buried beliefs or personal narratives. In general, you want to avoid using focus groups when the subject matter is polarizing, as people are less likely to be honest in a group setting. There are a few exceptions, such as when you are conducting focus groups with people who are not strangers and/or you are attempting to probe deeply into group beliefs and evaluations. But caution is warr
