By utilizing predetermined questions and a standardized format, researchers can gather reliable data while maintaining control over the interview process. Whether you’re a seasoned researcher or just starting out, understanding the nuances of these interviews is crucial for conducting effective qualitative studies. We’ll delve into best practices, potential pitfalls, and real-world examples to help you refine your structured interview techniques.

What do you need to conduct a structured interview?

Conducting structured interviews in qualitative research requires careful preparation and specific tools to ensure effective data collection. Generally, structured interviews are best when there is limited time to conduct the entire interview process. Structured interviews are among the four types of interviews in qualitataive research where both interviewer and interviewee have a discussion about the research phenomenon. Structured interviews are a common type of interview used in social science and political science research, offering a systematic approach to gather in-depth information on a research topic.

To conduct a structured interview, you’ll need:

1. Interview Guide: A well-prepared interview guide is crucial for structured interviews. This document contains predetermined questions in a set order, ensuring consistency across all interviews. The interview guide serves as a research tool that helps maintain focus on the research question and hypothesis.
2. Recording Equipment: Recording the interview is essential for accurate data collection. Use a reliable audio or video recorder to capture the interviewee’s responses, allowing for thorough data analysis later.
3. Consent Forms: Ethical research requires informed consent from participants. Prepare consent forms that explain the purpose of the study, significance of the study, how the data will be used, and the rights of the interviewee.
4. Note-taking Materials: While recording is important, taking notes during the interview can help capture non-verbal cues and body language that audio recordings might miss.
5. Quiet, Comfortable Setting: Choose a location that minimizes distractions and ensures privacy for the interviewee. This helps in conducting a focused interview and collecting quality data.
6. Trained Interviewers: Ensure that all interviewers are well-trained in the structured interview process, including how to ask questions in the same order and maintain consistency across interviews.
7. Sample Selection: Determine your sample size and selection criteria based on your research methodology and research budget.
8. Data Analysis Plan: Before conducting interviews, have a clear plan for how you will analyze your data, including any software or tools you’ll use for qualitative data analysis. A thematic data analysis process is recommended it help you see patterns within the transcripts from all participants included in the qualitative research interviews.

By having these elements in place, researchers can effectively conduct these interviews as a data collection method that relies on asking predetermined questions to collect data on a topic systematically. These tools and guides are also required when conducting open-ended structured interviews and in-depth interviews. A successfully conducted structured interview allows you to easily compare information from the interviewed participants. 

Examples of structured interview questions

Structured interviews in qualitative research typically include a set of questions asked in a specific order. Here are examples of structured interview questions across various research contexts:

1. Social Science Research:
   • “On a scale of 1 to 5, how satisfied are you with your current job?”
   • “How many hours per week do you spend on social media?”
   • “What is your highest level of education completed?”
2. Political Science:
   • “Did you vote in the last national election? Yes or No?”
   • “On a scale of 1 to 10, how would you rate the current government’s performance?”
   • “Which political party do you most closely align with?”
3. Market Research:
   • “How often do you purchase our product? Daily, Weekly, Monthly, or Rarely?”
   • “What factors influence your decision to buy this product?”
   • “Would you recommend our service to others? Yes or No?”
4. Healthcare Research:
   • “On average, how many hours of sleep do you get per night?”
   • “Have you been diagnosed with any chronic conditions? If yes, please list them.”
   • “How would you rate your overall health on a scale of 1 to 10?”

These examples demonstrate how structured interviews use a mix of close-ended and open-ended questions to collect data. While close-ended questions allow for easy comparison between participants, open-ended questions can provide richer, more detailed responses.

They are often used in quantitative research and surveys. Unstructured interviews, on the other hand, are more flexible and conversational, without a fixed set of questions.

They are commonly used in qualitative research methods to gather in-depth information. While structured interviews help you easily compare responses and see patterns, unstructured interviews allow for more exploration of emerging themes. Both types have their advantages and disadvantages depending on the research study’s goals.

2. What is an advantage of a structured interview?

A key advantage of structured interviews is their consistency, which allows researchers to easily compare responses between participants. This type of interview used in qualitative research provides a standardized format, making data analysis more straightforward and helping researchers see patterns more clearly. Structured interviews are particularly useful when conducting research with large sample sizes or when comparing results across different groups.

They also reduce interviewer bias, as all interviewees are asked the same questions in the same order. This consistency makes structured interviews valuable in both qualitative and quantitative research methods, especially when used alongside other data collection tools like questionnaires or surveys.

3. What is the format of a structured interview?

The format of a structured interview typically includes a set of predetermined questions asked in a specific order to all participants. This type of qualitative research method often uses a mix of closed-ended and open-ended questions. The interviewer follows a structured interview guide, ensuring consistency across all interviews.

Questions are carefully crafted to address the research study’s objectives and may include rating scales or multiple-choice options for easier quantification. The format allows for face-to-face interviews or remote interviews, depending on the research requirements. Structured interviews differ from other qualitative methods in their rigid format, which helps maintain consistency but may limit exploration of unexpected themes.

4. What is the difference between a structured interview and a semi-structured interview?

The main difference between structured interviews and semi-structured interviews lies in their flexibility. Structured interviews follow a rigid format with set questions in a set order, allowing for easy comparison between participants. Semi-structured interviews, while still having a predetermined set of questions, offer more flexibility to explore topics that arise during the conversation.

Semi-structured interviews are often used in qualitative research when a balance between consistency and depth is needed. They allow the interviewer to probe further into responses, unlike structured interviews. Both types are valuable qualitative research methods, but semi-structured interviews are generally better suited for in-depth exploration of complex topics.
