Strengths & Limitations of the In-depth Interview Method: An Overview

The following is a modified excerpt from Applied Qualitative Research Design: A Total Quality Framework Approach (Roller & Lavrakas, 2015, pp. 56-57).


The potential advantages or strengths of the in-depth interview (IDI) method reside in three key areas: (1) the interviewer–interviewee relationship, (2) the interview itself, and (3) the analytical component Two people talkingof the process. The relative closeness of the interviewer–interviewee relationship that is developed in the IDI method potentially increases the credibility of the data by reducing response biases (e.g., distortion in the outcomes due to responses that are considered socially acceptable, such as “I attend church weekly,” acquiescence [i.e., tendency to agree], and satisficing [i.e., providing an easy “don’t know” answer to avoid the extra cognitive burden to carefully think through what is being asked]) and nonresponse, while also increasing question–answer validity (i.e., the interviewee’s correct interpretation of the interviewer’s question).

An additional strength of the IDI method is the flexibility of the interview format, which allows the interviewer to tailor the order in which questions are asked, modify the question wording as appropriate, ask follow-up questions to clarify interviewees’ responses, and use indirect questions (e.g., the use of projective techniques) to stimulate subconscious opinions or recall. It should be noted, however, that “flexibility” does not mean a willy-nilly approach to interviewing, and, indeed, the interviewer should employ quality measures such as those outlined in “Applying a Quality Framework to the In-depth Interview Method.”

A third key strength of the IDI method—analyzability of the data—is a byproduct of the interviewer–interviewee relationship and the depth of interviewing techniques, which produce a granularity in the IDI data that is rich Read Full Text

“Did I Do Okay?”: The Case for the Participant Reflexive Journal

It is not unusual for an in-depth interview (IDI) or focus group participant to wonder at some point in an interview or discussion if the participant “did okay”; that is, whether the participant responded to the researcher’s questions in the Reflexivitymanner in which the researcher intended. For instance, an interviewer investigating parents’ healthy food purchases for their children might ask a mother to describe a typical shopping trip to the grocery store. In response, the mother might talk about the day of the week, the time of day, where she shops, and whether she is alone or with her children or someone else. After which she might ask the interviewer, Is that the kind of thing you were looking for? Is that what you mean? Did I do okay in answering your question? The interviewer’s follow up might be, Tell me something about the in-store experience such as the sections of the store you visit and the kinds of food items you typically buy.

It is one thing to misinterpret the intention of a researcher’s question – e.g., detailing the logistics of food purchasing rather than the actual food purchase experience – but another thing to adjust responses based on any number of factors influenced by the researcher-participant interaction. These interaction effects stem, in part, from the participant’s attempt to “do okay” in their role in the research process. Dr. Kathryn Roulston at the University of Georgia has written quite a bit about interaction in research interviews, including an edited volume Interactional Studies of Qualitative Research Interviews.

The dynamics that come into play in an IDI or focus group study – and in varying degrees, ethnographic research – are of great interest to qualitative researchers and important considerations in the overall quality of the research. This is the reason that a lot has been written about the researcher’s reflexive journal and its importance in Read Full Text

Narrative Research: Considerations in Gathering Quality Data

The following is a modified excerpt from Applied Qualitative Research Design: A Total Quality Framework Approach (Roller & Lavrakas, 2015, pp. 317-318).

The in-depth interview method most often used in narrative research takeStorytellings the form of the unstructured interview where the interviewer is not so much equipped with a series of questions or topics as a reminder of the research objective and areas where clarification or words of encouragement may be particularly appropriate. In lieu of a formal interview guide, the interviewer may want to enlist certain aids. For instance, Elliott (2005) suggests using a “life history grid” (e.g., a spreadsheet with each row representing a specific year and the columns used to record life events) to facilitate biographical interviews when narrators may need some structure in which to place their life events, beyond an open-ended question such as “Tell me about your life.” A Total Quality Framework approach to narrative research fully supports the life history grid and other tools that may enable the narrative researcher to obtain more complete and accurate data that ultimately lead to more credible and useful outcomes.

Another important consideration when conducting narrative research, particularly in the in-person mode, is the very close relationship that is likely to develop between the interviewer and the storyteller. For this reason, Read Full Text
