In-depth Interview Data: Achieving Quality From Cooperation

The following is a modified excerpt from Applied Qualitative Research Design: A Total Quality Framework Approach (Roller & Lavrakas, 2015, pp. 75-77)

cooperationAn important aspect related to Scope within the Credibility component of the Total Quality Framework (TQF) for qualitative research design is the extent to which the researcher is successful in gaining cooperation from the participants. In an in-depth interview (IDI) study, the researcher is concerned with the impact that the proportion of selected interviewees not interviewed or only partially interviewed has on the integrity of the data. This is the domain of research that is often termed “nonresponse.” If this proportion is large and/or if the group that is selected but not interviewed differs in meaningful ways from those who are interviewed, bias can infiltrate the final data of an IDI study and compromise the credibility of the research.

To avoid this, qualitative researchers need to give serious a priori thought to how they will gain high and representative levels of cooperation from the persons they have selected to interview, and how individuals who do not cooperate may differ in past experiences, attitudes, behaviors, and knowledge compared to interviewees. The researcher must keep in mind that bias may enter into the outcomes, and the credibility of the study’s findings and interpretations thereby weakened, if the characteristics of those in the sample who do not cooperate with an IDI study are correlated with the key topics the study is investigating. Likewise, qualitative researchers using the IDI method should also constantly monitor the representativeness of the group of selected participants that does cooperate and watch whether the characteristics of that group deviate from the characteristics of the target population. This may be difficult in the case of the email IDI (or other asynchronous text-based mode) where the interviewer must stay alert to the consistency of participants’ responses and recognize when the identity of the interviewee may have changed (i.e., someone other than the recruited research participant is the one now responding). For instance, in an email IDI study among Read Full Text

Limitations of the Focus Group Method: An Overview

The interactive, dynamic nature of group discussions (see “Strengths of the Focus Group Method: An Overview”) may also present a potential limitation to the method. The exchange of information and ideas may have the focus group limitationspositive effect of eliciting new insights, but it may also have the damaging effect of unwittingly influencing responses from participants who are reluctant to voice dissenting opinions and just want to go along with the prevailing mood. Although a professional moderator can often identify the more introverted or shy participants in a group and use rapport-building techniques to encourage their candidness, these attempts are not always successful and the research outcomes may reflect more agreement on an issue than is actually warranted. Whether the nonexistence of differing attitudes among group participants is due to the reluctance of people to speak their minds or an honest reflection of personal points of view, some researchers can easily fall into the trap of believing that this lack of opposing attitudes is the same as a group consensus. As stated by Sim (1998, p. 348), “the absence of diversity in the data does not reliably indicate an underlying consensus” but is rather a possible product of the group environment, which may mask individual opinions.

Alongside the potential downside of group dynamics is the critical role of the moderator. Professional moderators trained in the complexities of group interviewing are essential to the success Read Full Text

Strengths of the Focus Group Method: An Overview

The following is a modified excerpt from Applied Qualitative Research Design: A Total Quality Framework Approach (Roller & Lavrakas, 2015, pp. 111-112).


The unique advantage of the group discussion method is clearly the participant interaction and what it adds to (goes beyond) what might be learned from a series of in-depth interviews (IDIs). When conducted to achieve its full potential, the back-and-forth dialFocus groupsogue among the participants benefits the researcher (and the quality of the data) in several important respects:

  • A dynamic group discussion will often stimulate spontaneous ideas and personal disclosures that might otherwise go unstated in an IDI.
  • A relaxed, interactive, as well as a supportive (e.g., homogeneous) group environment can be conducive to discussing sensitive topics (e.g., a discussion of the immigration process among recent Chinese immigrants to the United States).
  • As participants exchange opinions, they consider their own views in relation to others’—which may encourage participants to refine their thoughts. In this way the group interaction gives the researcher insight into how people think about the topic(s) being studied and on what basis opinions may change. For example, in a focus group with college students who are considering various study-abroad programs, some participants might change their criteria for selecting one program over another after hearing other participants’ considerations. This discussion would help the researcher identify the important aspects of study-abroad programs that may impact students’ decision making.

Participant interaction, or the social aspect of focus group discussions, can be a particularly important advantage when conducting research with vulnerable and underserved population segments. For instance, women’s studies researchers such as Wilkinson (1999) believe that focus groups offer feminist psychologists an important research approach over other psychological research Read Full Text
