Designing effective interviews: From research questions to data collection
When embarking on a research journey, one of the most crucial decisions you will make is which data collection method to employ. Successful interviews rely on well-crafted research questions, thoughtful sampling strategies, appropriate data collection techniques, and rigorous data analysis methods. Through a well-designed interview, you can uncover new perspectives, shed light on pressing issues, and generate valuable insights. Let’s dive in!

Structured interviews
Structured interviews are meticulously planned, with predetermined questions asked in a consistent order. This method is advantageous when your research requires specific, quantifiable data. It ensures uniformity in the interview process, making it easier to compare and analyze subjects’ responses.
Structured interviews are particularly useful in situations where you have a well-defined research question and want to maintain control over the data collection process. For example, when studying customer satisfaction with a product, you might use structured interviews to ask participants about their experience using a set of standardized questions. These interviews often include closed-ended questions with predetermined response options.
Insider tips
- Develop a standardized set of questions that directly address your research objectives.
- Use closed-ended questions with predefined response options for quantitative data.
- Consider conducting a pilot interview to refine your questions and ensure clarity.
Illustrative scenario
Imagine you are researching customer satisfaction with a new mobile app. You could use structured interviews to ask participants to rate the app’s user-friendliness on a scale from 1 to 5, with 1 being “very difficult” and 5 being “very easy.”
Semi-structured interviews
Semi-structured interviews strike a balance between structure and flexibility. They begin with a set of core questions, but the interviewer can adapt and expand on them based on the participant’s responses. This approach allows for more in-depth exploration of topics and can help you uncover unexpected insights.
When your research requires a deeper understanding of complex issues or when you want to capture participants perspectives and experiences, semi-structured interviews are a valuable choice. For example, if you are researching the challenges faced by healthcare workers during a pandemic, semi-structured interviews can elicit detailed narratives that go beyond predefined categories.
Insider tips
- Start with open-ended questions that encourage participants to share their perspectives.
- Prepare follow-up questions to dig deeper into interesting points raised by participants.
- Allow for pauses and silences to let participants gather their thoughts.
Illustrative scenario
Suppose you’re researching the experiences of teachers providing remote education. You could start with a broad question like, “Can you describe your biggest challenges as a remote teacher?” and then follow up with more specific inquiries based on the teacher’s response.
Unstructured interviews
Unstructured interviews provide the most flexibility and freedom for both the interviewer and the participant. There are no predefined questions, allowing the conversation to flow naturally. This method is particularly beneficial when exploring entirely new topics or when seeking to understand diverse viewpoints on a subject.
Unstructured interviews are ideal when you want to encourage participants to express themselves freely and openly. For instance, in a study on the impact of art therapy on mental health, unstructured interviews can reveal the unique and personal experiences of each participant, providing rich qualitative data.
Insider tips
- Begin with a broad opening question to encourage participants to share their thoughts freely.
- Let the conversation evolve organically, following the participant’s lead.
- Be an active listener, prompting the interviewee to elaborate on interesting points.
Illustrative scenario
In a study on the impact of art therapy on mental health, you might simply start with,“Tell me about your experiences with art therapy,” and then let the participant guide the conversation, sharing their personal journey and insights.
Final tip: Successful interviews require thoughtful questions
Remember, the success of your research hinges not just on the interview type but also on your ability to craft thoughtful and insightful questions. So, whether you opt for structure, flexibility, or open-ended discussion, the key lies in your skill as an interviewer and your alignment with your research goals.
To cap it off
Selecting the right interview approach for your research is crucial for collecting meaningful and relevant data. Structured interviews offer control and precision, semi-structured interviews enable exploration and depth, and unstructured interviews promote free expression. The choice ultimately depends on your research goals and the nature of your questions.
By understanding the advantages and appropriate use cases for each interview type, you can design a study that captures the insights you seek and advances your research objectives. So, when planning your next project, consider the interview approach that aligns best with your research.
