Unstructured interviews

Unstructured interviews, often referred to as non-directive interviews, are highly conversational and flexible. In this method, the interviewer may start with a general topic but allows the conversation to flow naturally, encouraging the participants to share their thoughts and experiences freely. Unstructured interviews are particularly effective for exploring new or complex research topics where the researcher seeks to uncover unexpected insights. The open-ended nature of these interviews can yield rich, detailed data, but the lack of structure can make it difficult to compare responses across participants and can lead to a more time-consuming data collection process.

When to use unstructured interviews

Unstructured interviews are particularly well-suited for exploratory research where the goal is to develop a deep understanding of a phenomenon, especially when there is little existing theory to guide the research. This approach is often used in studies that aim to gather “thick descriptions,” a term that refers to the detailed exploration of a respondent’s perspectives to understand the complexity of social phenomena. For example, in studies examining sensitive topics such as hospice care or migrant work, respondents might be more hesitant to open up if they are confronted with direct or structured questions. Unstructured interviews allow researchers to build rapport with participants, creating a more comfortable environment for them to share their thoughts and experiences openly. When the primary objective is to develop trust and rapport, unstructured interviews offer an effective way to engage participants. The lack of a rigid structure allows the conversation to flow more naturally, which can make respondents feel more at ease, thereby increasing the likelihood of collecting meaningful data.

Advantages of unstructured interviews

One of the main advantages of unstructured interviews is their open-ended nature, which allows the conversation to move in any direction that may arise naturally. While the interviewer typically has a clear research objective, the lack of a rigid structure gives respondents greater control over the interaction. This can encourage them to provide more detailed and in-depth answers, particularly when discussing sensitive topics or personal experiences. The freedom to explore respondents' perspectives in greater depth makes unstructured interviews ideal for studies that aim to gather rich, qualitative data. Researchers can gain a more nuanced understanding of the respondent’s viewpoints, social customs, or cultural practices, especially in areas where existing knowledge is limited.

Disadvantages of unstructured interviews

Despite their advantages, unstructured interviews come with several challenges. One of the primary drawbacks is the difficulty in analyzing and comparing the data collected from different participants. Because each respondent may focus on different aspects of the topic, the data can be diverse and less consistent, making it challenging to integrate different perspectives into a coherent analysis. Another potential disadvantage is the risk of the conversation straying too far from the research topic. Since there is no predetermined set of questions, the interviewer must carefully manage the flow of the conversation to ensure that valuable information is being gathered. If the interviewer loses focus, the interview might venture into unrelated tangents, resulting in irrelevant data.

Unstructured interview process

Although unstructured interviews do not follow a set list of questions, they still require careful planning. The interviewer should have a clear understanding of the research topic and the objectives they aim to achieve. While there might not be specific questions to guide the interview, the interviewer should have a set of key topics they want to explore during the conversation. Another crucial aspect of unstructured interviews is the interviewer’s ability to adapt to the conversation in real-time. This means knowing when to ask more probing questions and when to let the respondent steer the conversation. The ability to read social cues and adjust questioning based on the respondent’s comfort level is essential for successful data collection in this format. The data collection phase in unstructured interviews can be one of the most dynamic aspects of the research process. Since there is no predetermined script, the interviewer must navigate the conversation with care, encouraging the respondent to share detailed narratives. Building rapport is essential, as it fosters an environment where respondents feel comfortable discussing their thoughts openly. The interviewer should aim to gather detailed accounts from the respondents while avoiding leading questions that may influence their responses. Starting with simple, non-threatening questions is a good way to build rapport before moving on to more complex or sensitive topics.

How to analyze unstructured interviews

Analyzing unstructured interview data requires a systematic approach to make sense of the often-varied responses. Typically, interview data is transcribed, allowing the researcher to search for important phrases, patterns, or insights. Qualitative data analysis software like ATLAS.ti can be used to assist with organizing and coding the data. The software helps researchers identify key themes and compare responses across different participants. Coding is an essential part of the analysis process. Researchers can begin by creating a list of preliminary codes based on their research questions, but they should remain open to new codes as they analyze the data. For example, they might conduct a thematic analysis, which involves identifying recurring themes or shared experiences across respondents. Unstructured interviews can also be analyzed using discursive coding, which focuses on how respondents talk about a particular phenomenon. This approach is useful when the goal is to explore how individuals construct meaning around the topic of interest.
