Developing a guide for an in-depth interview (IDI) or focus group discussion requires careful consideration of the research objectives and the constructs under investigation. Many articles in Research Design Review discuss guide development, including “Interview & Discussion Guide Development: A 4-Stage Funnel Approach” and “Guide Development & the Integrity of Qualitative Research Data.”
An important way to teach and learn best practices in guide development is to examine how other researchers have constructed their guides. Unfortunately, access to others’ IDI or focus group guides is limited due to the fact that many of the qualitative studies published in the literature do not include the guide used in the research.
One exception is a focus group study published a few years ago concerning the dietary behaviors among community residents. The primary questions asked in these discussions are included in the Appendix of the published article. These questions and the order in which they were asked (see below) offer a case for discussing quality guide development. For the sake anonymity, slight modifications have been made to the study details (i.e., “fish” replaces the actual food type under investigation and the segment of community residents who participated is not revealed).
Take a look at this basic guide structure (i.e., the primary questions minus the probing questions) and think about how, if at all, you would change the design of the questions and/or the order in which the questions are asked. As you do so, keep in mind the stated research objective. Part 2 of the discussion here in RDR will propose an alternative solution to this guide.
