13.1 Interview research: What is it and when should it be used?

Learning Objectives

  • Define interviews from the social scientific perspective
  • Identify when it is appropriate to employ interviews as a data-collection strategy

 

Knowing how to create and conduct a good interview is an essential skill. Interviews are used by market researchers to learn how to sell their products. Journalists use interviews to get information from a host of people, from VIPs to random people on the street. Police use interviews to investigate crimes. It seems everyone who’s anyone knows how to conduct an interview.

In social science, interviews are a method of data collection that involves two or more people exchanging information through a series of questions and answers. The questions are designed by a researcher to elicit information from interview participants on a specific topic or set of topics. These topics are informed by the author’s research questions. Interviews typically involve an in-person meeting between two people (an interviewer and an interviewee), but interviews need not be limited to two people, nor must they occur in-person.

You may be wondering when you should choose interviews as your data collection method. Interviews are an excellent way to gather detailed information. They also have an advantage over surveys, as they can be adapted as you learn more information. Recall that survey data collection methods do not allow researchers to change the questions that are administered, even if a participant’s response sparks some follow-up question in your mind. All participants must be asked the same questions in the same manner. The questions you decided to put on your survey during the design stage determine what data you get. In an interview, however, you can follow up on new and unexpected topics that emerge during the conversation. Trusting in emergence and learning from your participants are hallmarks of qualitative research. In this way, interviews are a useful method to employ when you want to know the story behind the responses you might receive in a written survey.

Interviews are also useful when your topic is rather complex, requires lengthy explanation, or needs a dialogue between two people to thoroughly investigate. Additionally, interviews may be the best method to utilize if your study involves describing the process by which a phenomenon occurs, like how a person makes a decision. For example, you could use interviews to gather data about how people reach the decision not to have children and how others in their lives have responded to that decision. To understand these processes, you would need to exchange dialogue with respondents. When they begin to share their story with you, new questions that hadn’t occurred to you in prior interviews will arise because each person’s story is unique. Further, closed-ended survey questions would not be as effective in capturing the complex process of choosing not to have children.

In sum, interview research is especially useful when the following are true:

  • You wish to gather very detailed information
  • You anticipate wanting to ask respondents follow-up questions based on their responses
  • You plan to ask questions that require lengthy explanation
  • You are studying a complex or potentially confusing topic to respondents
  • You are studying processes, such as how people make decisions

 

Key Takeaways

  • Understanding how to design and conduct interview research is a useful skill to have.
  • In a social scientific interview, two or more people exchange information through a series of questions and answers.
  • Interview research is often used when detailed information is required and when a researcher wishes to examine processes.
