Codebooks in Qualitative Content Analysis
Content analysis is a research method that helps turn large amounts of textual data into a cohesive narrative. It helps you use data from different textual sources like newspapers or journals, extract key details, and then offer results grounded in that data. A key tool in this process is a codebook, which helps structure how you categorize and interpret your data.
While you can do quantitative content analysis or qualitative content analysis, this article offers qualitative codebook examples with practical guidance on creating them for your own qualitative research.
What is Content Analysis?
Imagine you have a pile of newspaper articles to examine. The articles are published in different newspapers at various times and places. Content analysis helps you look at how often certain words or ideas appear in what people are saying or writing across the articles.
You can think of all content analysis, like keeping score of these keywords or ideas to figure out what really matters across all of the articles. The more a specific word or idea pops up, the more attention it should probably get. So, content analysis helps you understand what's getting the most attention (by using frequency to tell you where to look) and why it might be important.
Research that stops at frequency is quantitative content analysis. But in qualitative content analysis, you go “beyond merely counting words to examining language … for the purpose of classifying large amounts of text into … categories that represent similar meanings.” [1]
So, as you develop your qualitative content analysis, the keywords or ideas that pop up most frequently become ‘codes' in your codebook — covered in more detail down below.
In short, qualitative content analysis helps analyze and interpret large amounts of text by using frequency as a measuring stick, allowing you to uncover deeper insights hidden within the data.
⚠️There are various subtypes of content analysis. Frequency is a key focus in most cases, but there are exceptions. Learn more in our practical guide to qualitative content analysis.
Codebooks in Content Analysis
Using a codebook in content analysis helps you draw verifiable conclusions from text-based research. It outlines each code's definition, provides examples, often tabulates frequency counts, and sets out your coding rules, giving you clear guidelines for categorizing and analyzing your data effectively and consistently.
Consistency is particularly important during collaborative content analysis where you are coding large amounts of data with a team. A shared codebook makes sure everyone is applying the code in the same way, which you confirm through one or several methods of researcher triangulation.
You can also publish your codebook alongside your results for an added layer of transparency, letting readers see exactly how you came to your conclusions. This strengthens the credibility of your findings and enables others to replicate or build upon your research, fostering a more open and reliable research community.
For these purposes, researchers increasingly rely on qualitative coding tools like Delve, which streamline the coding process in content analysis.
Codebook Example in Qualitative Content Analysis
To illustrate the importance of using a codebook in qualitative content analysis, let's look at some real-world examples where codebooks played a vital role:
1. Body Positivity on Instagram (Cohen et al., 2019)
This study investigated body-positive posts on Instagram using content analysis. A codebook was used to code the 640 Instagram posts sampled, and it had been created based on “theoretical concepts, prior content analyses of social media content, and a scoping review of body positive content.” (p. 10) This paper has been cited 383 times, which is impressive considering that it was published in 2019. The codebook is clear and comprehensive, which makes it a great example for new researchers to study.

2. Media Frames in Biotechnology (Matthes & Kohring, 2008)
This study discussed methodological issues in the content analysis of media frames and proposed a new approach that would increase the reliability and validity of the analysis. By focusing on how biotechnology was covered in a major publication like The New York Times, the codebook helped the researchers dissect complex media narratives and their underlying messages. This paper has been cited 1543 times, which indicates this is a highly trusted paper.

3. Cannabis Company Marketing (Moreno et al., 2022)
The authors of this study used a retrospective content analysis to evaluate Facebook and Instagram posts by recreational cannabis companies in four states. The codebook was adapted from a similar study in which the authors conducted content analysis on Facebook posts on cannabis use in Washington State. The codebook used was ideal for this particular study, but it includes some features that are not present in other content analysis codebooks. This shows that there is flexibility in what a codebook might look like.

Creating and Using a Codebook in Content Analysis
A codebook in qualitative content analysis starts with codes derived from your own analysis or existing research literature. It can use inductive coding, forming codes from your own insights, or deductive coding, where you try to replicate or build upon existing qualitative studies.
The key to a good codebook is to keep it clear, concise, and comprehensive, reflecting changes and discoveries made during the research process. Your codebook should include:
Code Definitions: Clear descriptions of each category or theme.
Coding Rules: Guidelines on how to assign text to categories.
Examples: Samples of text that illustrate each category.
Keep in mind that your codes may evolve throughout your research as new details emerge, especially when taking an inductive approach. That being said, all qualitative content analysis is an iterative process, highlighting the need for a well-organized codebook to manage your work.
