What is an interview and its purpose in qualitative research?

Interviews, as a qualitative research method, play a key role in uncovering complexities in human behavior and decision-making. Researchers can observe behavior, on the one hand, or they can investigate the perspectives and values informing that behavior by interviewing research participants.

Purpose and importance

Interviews allow researchers to collect data on the subjective experiences of individuals, providing insights that may not be accessible through other research methods. They illuminate people’s perceptions, thoughts, feelings, and understandings about a particular phenomenon. Data representing these views can form the foundation for identifying recurring themes regarding that phenomenon.

Unlike quantitative methods, which typically collect numerical data that can be statistically analyzed, interviews capture rich, detailed data in the form of words, ideas, and themes. They allow researchers to collect data on people’s experiences in a manner that is sensitive to the context and the individual’s perspective. Through interviews, researchers can explore the meanings people attribute to their experiences and gain a deeper understanding of the phenomena being studied.

Interviews also empower participants by giving them a voice. The interviewee has the opportunity to express their views, feelings, and experiences in their own words. This participatory aspect of interviews underscores the respect for individual experiences and perspectives, which is a central tenet of qualitative research.

Comparing interviews with other methods

While interviews share many similarities with other qualitative methods, they also have unique features that set them apart. Unlike interviews, methods like observations are more passive and rely more on the researcher’s interpretation of events.

On the other hand, interviews actively involve participants in the data generation process. Compared to surveys, which may limit responses to predetermined choices or word limits, interviews allow for open-ended responses and the flexibility to explore topics in depth.

However, it’s worth noting that interviews do not have to be a stand-alone method. They are often used with other methods, such as observation or document analysis, in a multi-method or mixed-methods research design. This combination of methods can enhance the richness and credibility of the data collected, providing a more holistic understanding of the research problem.
