Learning how to develop research questions is a big step in designing your research study and forces you to think about what you want to know as you gather data from your participants. No longer is the topic you’ve selected just a hypothetical issue you’re interested in addressing; once you have written the research questions, you realize that you must explain to the reader exactly what it is that you want to know at the end of your research. However, I often talk with dissertation writers who are confused with the difference between research questions and interview questions. Or, I will be reviewing draft interview questions for a client and come across questions that are much more suited for interview questions.
What, then, is the difference between research questions and interview questions? In short, research questions are questions you want to answer by completing your study. Interview questions are questions you ask of your participants to help you address your research questions. Sounds like circular logic, doesn’t it? Let’s dig a little deeper.
The need for interview questions is self-evident: you have participants and so you need to ask them questions in a qualitative study in order to collect data. So, why do you need research questions? Research questions are the pillars of your study: those key concepts you want to explore so that you can address the gap you have identified. See the image below:

Examples of research questions
What can we do to learn how to develop research questions? Writing the research questions is dependent upon several things: (1) the problem or gap you have identified, (2) the purpose of your study, (3) the qualitative approach you are using, and, sometimes (4) your theoretical framework. Let’s look at an example:My problem statement is:
Instructional barriers exist for nursing educators in teaching with full body patient simulators remotely when instruction on campus is limited due to the global pandemic.
The gap I’ve identified is:
While there is extensive literature on the use of full body patient simulators in on-campus nursing instruction(citation of several sources would be listed here in a real example), there is a lack of research on how nursing educators can modify this instruction when learning is remote.
The purpose statement is:
The purpose of this qualitative descriptive study is to explore how nursing educators describe their strategies in teaching with full body patient simulators in remote delivery for ASN nursing students at a community college.
The theoretical framework I’ve chosen is:
Self-efficacy theory by Albert BandurIn the above, I have addressed all four elements that I’ll need for creating my research questions, including #3, the qualitative approach. I’ve sneaked that into my purpose statement by writing, “this qualitative descriptive study.” Given that we know these four things, now we can begin writing our research questions.
