Preparing Questions for a Qualitative Research Interview

A qualitative research interview is an invaluable tool for researchers. Whether one’s studying social phenomena, exploring personal narratives, or investigating complex issues, interviews offer a means to gain unique insights. 

“The quality of the data collected in a qualitative research interview is highly dependent on the quality and appropriateness of the questions asked.”

But how do you prepare the right questions to ensure your interviews yield rich data? In this guide, we’ll explore the types of qualitative research interviews and provide tips for crafting effective questions.

Types of Qualitative Research Interviews

Before diving into question preparation, it’s important to select the type of qualitative research interview that’s best suited for the study at hand.

There are three types of qualitative research interviews:

Structured Interviews 

Structured interviews involve asking the same set of pre-written questions to every participant. This approach ensures consistency, making it easier to compare data between participants or groups later.

When conducting structured interviews, keep these guidelines in mind:

1. Pre-written Questions: All questions, including probes, should be meticulously written in advance.
2. Detailed Questions: Questions should be detailed enough to be used verbatim during interviews.
3. Consistent Sequence: The sequence of questions should be pre-decided and consistent across interviews.

Example of a Structured Interview Question

Question: Thinking back to your childhood days in Chelsea, can you remember what kind of local music was popular at the time?

Probes:

• Why do you think it was so popular?
• Where was it played?
• Were there other popular genres?

Structured interviews are ideal when you need uniform data collection across all participants. They are common in large-scale studies or when comparing responses quantitatively.

Semi-structured Interviews 

The second type of qualitative interviews are semi-structured interviews. In these interviews, the interview guide outlines the topics to be explored, but the actual questions are not pre-written.

This approach allows interviewers the freedom to phrase questions spontaneously and explore topics in more depth.

Example of a Semi-Structured Interview Question

Question: What problems did the participant face growing up in the community?

Subtopics:

• Personal.
• Education-related.
• Related to their immediate family.
• Related to the community in general.

Semi-structured interviews strike a balance between flexibility and structure. They offer a framework within which interviewers can adapt questions to participants’ responses, making them suitable for in-depth exploration.

Unstructured Interviews 

In unstructured interviews, often referred to as informal conversational interviews, are characterized by a lack of formal guidelines, predefined questions, or sequencing.

Questions emerge during the interview based on the conversation’s flow and the interviewee’s observations. Consequently, each unstructured interview is unique, and questions may evolve over time.

Unstructured interviews are highly exploratory and can lead to unexpected insights. They are particularly valuable when studying complex or novel phenomena where predefined questions may limit understanding.

Deciding What Information You Need

Once you’ve chosen the type of interview that suits your research study, the next step is to decide what information you need to collect.

Patton’s six types of questions offer a framework for shaping your inquiries:

1. Behavior or Experience: Explore participants’ actions and experiences.
2. Opinion or Belief: Probe participants’ beliefs, attitudes, and opinions.
3. Feelings: Delve into the emotional aspects of participants’ experiences.
4. Knowledge: Assess participants’ understanding and awareness of a topic.
5. Sensory: Investigate how participants perceive and interact with their environment.
6. Background or Demographic: Collect information about participants’ personal characteristics and histories.

Based on these categories, create a list of the specific information you aim to collect through the interview. This step ensures that your questions align with your research objectives.

Writing the Qualitative Research Interview Questions

After deciding the type of interview and nature of information you’d like to gather, the next step is to write the actual questions. 

Using Open-Ended Questions

Open-ended questions are the backbone of qualitative research interviews. They encourage participants to share their experiences and thoughts in-depth, providing rich, detailed data.

Avoid ‘yes’ or ‘no’ questions, as they limit responses. Instead, use open-ended questions that grant participants the freedom to express themselves. Here are some examples – 

Examples of Open-Ended Questions

1. How do you feel about working at ABC Corp. during your initial years there?

   • Encourages participants to share their emotions and experiences.

2. Can you describe the attitudes and approach to work of the other people working with you at the time?

   • Invites participants to reflect on their colleagues’ behaviors and attitudes.

3. Tell me more about your relationship with your peers.

   • Encourages participants to provide narrative insights into their relationships.

Going from Unstructured to Structured Questions

Unstructured Questions allow the interviewee to guide the conversation, letting them focus on what they think is most important.

These questions make the interview longer, but also provide richer and deeper insight.

Examples of Unstructured Questions

• Tell me about your experience working at [xxx].
• What did it feel like to live in that neighborhood?
• What stood out to you as the defining characteristic of that neighborhood?

Examples of Structured Questions

• What are some ways people dealt with the health issues caused by excessive chemical industries in the neighborhood?
• As an employee at ABC Corp. during the time, did you observe any specific actions taken by the employers to address the issue?

Probing Questions

Probing questions are used to get more information about an answer or clarify something. They help interviewers dig deeper, clarify responses, and gain a more comprehensive understanding.

Examples of Probing Questions

1. Tell me more about that.

   • Encourages participants to elaborate on their previous response.

2. And how did you feel about that?

   • Invites participants to share their emotional reactions.

3. What do you mean when you say [xxx]?

   • Seeks clarification on ambiguous or complex statements.

Probing questions enhance the depth and clarity of the data collected, however they should be used judiciously to avoid overwhelming participants.

A General Last Question

As your interview approaches its conclusion, it’s beneficial to have a general last question that allows the interviewee to share any additional thoughts or opinions they feel are relevant.

For instance, you might ask:

Thank you for all that valuable information. Is there anything else you’d like to add before we end?

This open-ended question provides participants with a final opportunity to express themselves fully, ensuring that no critical insights are left unshared.

Conclusion

Preparing questions for qualitative research interviews requires a thoughtful approach that considers the interview type, desired information, and the balance between structured and unstructured questioning.
