How to easily code your interviews

Learn how you can easily code your interviews for your research with this guide.

How to Start Coding Interviews for Your Research

Coding is an essential step in qualitative research, where you collect rich, detailed data by analyzing and categorizing interviews. The process starts with transcribing audio recordings into text, which serves as the foundation for further analysis. It is a meticulous task that requires concentration and accuracy, but with modern technologies such as automatic transcription, like those offered by Audiogest, this step has become easier and faster. Notably, Audiogest is very proficient in transcribing the Dutch language.

Step 1: Transcribing Your Interview

Transcription is the process of converting spoken words, usually recorded in interviews, into a written form. This is a crucial step because it produces a tangible and analyzable document of the audio or video recordings. The importance of transcribing within the coding process lies in accuracy; errors or missing text can skew the results of the research.

There are various methods of transcription, including manual transcription by a transcriber or automatic transcription using software. Automatic transcription, such as the services provided by Audiogest, offers a fast and cost-effective way to transcribe interviews, which is also convenient when you have conducted a large number of interviews. The choice of transcription method depends on factors such as required accuracy, available budget, and the complexity of the audio file.

Step 2: Laying the Groundwork for Coding

After transcribing the interviews, the actual coding process begins. This process broadly consists of three phases: open coding, axial coding, and selective coding. Open coding involves diving into the data, identifying significant text fragments, and labeling them. It is an exploratory phase where you establish connections and identify themes.

It is important to realize that coding is not a strictly linear process. A researcher can move back and forth between the phases, depending on what the data reveal. This cyclical process allows for in-depth data analysis and ensures that the coded labels are an accurate representation of the interview data. Labels help in structuring the data and building a framework for the analysis.

Types of Coding

In qualitative research, coding is key to discovering patterns, themes, and categories within large amounts of data. This process is especially crucial when analyzing textual data, such as interview transcripts. There are various coding techniques that researchers can use, depending on the nature and phase of their research. Let's look at the different types of coding:

Open Coding

Open coding is the process where researchers go through the data, identify text fragments that seem interesting, and provide them with codes and labels. This phase of coding is characterized by an exploratory approach; it involves thoroughly going through the data to discover as many categories, patterns, and themes as possible. During open coding, you often do not know exactly what you are looking for, which means that you approach the data without preconceived expectations.

An example of open coding in an interview might be when a respondent talks about their daily work activities, and the researcher assigns labels such as "workflow," "daily challenges," and "job satisfaction" to different statements within the interview.

Example of Open Coding

Imagine a hypothetical study on the use of Artificial Intelligence (AI) for writing articles. A researcher listens to an interview and extracts interesting text fragments. When labeling these fragments, the researcher will apply open coding.

Below is an example table with text fragments from the interview and the possible codes that could be applied during open coding:

Text Fragment Code
"I use an AI tool to generate the first draft of my articles." AI use in writing process
"Sometimes the generated text is surprisingly coherent and useful." Quality of AI-generated text
"Editing the AI content takes more time than I expected." Editing time
"I rely on the AI to help me with my writer's block." AI as a tool against writer's block
"There is a learning curve to using the software effectively." Learning curve in AI use

During the open coding process, these codes can then be clustered into broader categories and themes, which form the basis for further analysis in the research.

Axial Coding

Axial coding is a step deeper in analyzing and structuring the data after open coding. In this phase, the aim is to find relationships between the open codes. The categories discovered in open coding are related to their subcategories, and the connections between them are made explicit.

Using the AI study example, the codes "AI use in writing process" and "Quality of AI-generated text" could be related under a broader category such as "AI Effectiveness." Similarly, "Editing time" and "Learning curve in AI use" might be related under a category like "AI Integration Challenges."

Selective Coding

Selective coding is the phase where the researcher starts to weave a narrative from the established categories and subcategories, identifying a central theme that runs through the data. It's about pinpointing the "core category" that represents the main theme of the research. The core category should appear frequently throughout the data and have the strongest connections to other categories.

In our AI article writing example, the central theme might be "The Impact of AI on Writing Practices." This core category would encompass all other categories and codes, and the researcher would structure the final report around this central theme.

By methodically analyzing and coding the interviews, researchers can uncover deep insights and answer the research questions. The iterative nature of coding means that as new data are collected or as existing data are reexamined, codes and categories can be refined, which may lead to new insights and a richer understanding of the research topic.
