If you’re writing an academic paper, you may need to cite a case study. But how do you do that? This guide will explain everything you need to know about citing a case study in APA format.
Table of Contents
APA stands for American Psychological Association. It is a style guide used by many academic disciplines, including psychology, sociology, and business. The purpose of the APA style is to provide a consistent format for academic writing, making it easier for readers to understand and follow the author’s argument.
Citing a case study is important for several reasons. First, it gives credit to the original author for their work. Second, it allows readers to find the source if they want to learn more. Finally, it adds credibility to your work by demonstrating that you have researched and referenced other relevant studies.
Here are the steps you need to follow to cite a case study in APA format:
The first step in citing a case study is to list the author’s last name and first initial. For example Smith, J.
Next, you need to include the year of publication in parentheses. For example: (2018).
After the year of publication, you need to provide the title of the case study in italics. For example The impact of social media on adolescent mental health.
The next step is to add the name of the publisher. For example Harvard Business Review Press.
Finally, you need to include the DOI or URL where the case study can be found. For example https://doi.org/10.1145/1234567.1234567
Here’s what the final citation should look like:
Smith, J. (2018). The impact of social media on adolescent mental health. Harvard Business Review Press. https://doi.org/10.1145/1234567.1234567
If you cannot find a DOI or URL for the case study, you can omit it from the citation. In that case, you should include the name of the database where you found the case study instead. For example:
Smith, J. (2018). The impact of social media on adolescent mental health. Harvard Business Review Press. Academic Search Complete.
Citing a case study in APA format may seem daunting at first, but it is quite simple once you know the steps. By following the guidelines in this article, you can ensure that your citations are accurate and complete and that you are giving credit to the original authors for their work.

The APA Manual does not include instructions on how to cite a Harvard Business Review case study. When citing case studies in APA style you will want to include the typical citation elements and apply general formatting guidelines. The following are examples of how case studies could be cited in APA style, but be sure to check with your professor about how they would like you to cite case studies in your work.

Particularly in research for business studies or papers in the social sciences, you may want to cite a case study completed by a university or other organization. While case studies have titles and publication information like other articles, they often have a unique case study number that is typically included in your citation. While Chicago citation style is most frequently used in business schools, you may also use the American Psychological Association (APA) or Modern Language Association (MLA) style.

A case study is a detailed study of a specific subject, such as a person, group, place, event, organisation, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.
A case study research design usually involves qualitative methods , but quantitative methods are sometimes also used. Case studies are good for describing , comparing, evaluating, and understanding different aspects of a research problem .
When to do a case study, step 1: select a case, step 2: build a theoretical framework, step 3: collect your data, step 4: describe and analyse the case.
A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.
Case studies are often a good choice in a thesis or dissertation . They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.
You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.
Research question | Case study |
---|---|
What are the ecological effects of wolf reintroduction? | Case study of wolf reintroduction in Yellowstone National Park in the US |
How do populist politicians use narratives about history to gain support? | Case studies of Hungarian prime minister Viktor Orbán and US president Donald Trump |
How can teachers implement active learning strategies in mixed-level classrooms? | Case study of a local school that promotes active learning |
What are the main advantages and disadvantages of wind farms for rural communities? | Case studies of three rural wind farm development projects in different parts of the country |
How are viral marketing strategies changing the relationship between companies and consumers? | Case study of the iPhone X marketing campaign |
How do experiences of work in the gig economy differ by gender, race, and age? | Case studies of Deliveroo and Uber drivers in London |
Once you have developed your problem statement and research questions , you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:
Unlike quantitative or experimental research, a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.
If you find yourself aiming to simultaneously investigate and solve an issue, consider conducting action research . As its name suggests, action research conducts research and takes action at the same time, and is highly iterative and flexible.
However, you can also choose a more common or representative case to exemplify a particular category, experience, or phenomenon.
While case studies focus more on concrete details than general theories, they should usually have some connection with theory in the field. This way the case study is not just an isolated description, but is integrated into existing knowledge about the topic. It might aim to:
To ensure that your analysis of the case has a solid academic grounding, you should conduct a literature review of sources related to the topic and develop a theoretical framework . This means identifying key concepts and theories to guide your analysis and interpretation.
There are many different research methods you can use to collect data on your subject. Case studies tend to focus on qualitative data using methods such as interviews, observations, and analysis of primary and secondary sources (e.g., newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data .
The aim is to gain as thorough an understanding as possible of the case and its context.
In writing up the case study, you need to bring together all the relevant aspects to give as complete a picture as possible of the subject.
How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis, with separate sections or chapters for the methods , results , and discussion .
Others are written in a more narrative style, aiming to explore the case from various angles and analyse its meanings and implications (for example, by using textual analysis or discourse analysis ).
In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates.

Properly citing case studies plays a crucial role in academic writing for several reasons. Firstly, citing case studies demonstrates the credibility and reliability of your arguments and research. By referencing the original sources, you show that you have conducted thorough research and have used reputable and authoritative information to support your claims.
Secondly, citing case studies allows readers to further explore the topic and verify the information provided. It enables them to locate and read the full case study if they wish to delve deeper into the details and findings. This promotes transparency and fosters a more comprehensive understanding of the subject matter.
Finally, citing case studies acknowledges the contributions of the original authors and researchers. By giving proper credit, you adhere to ethical standards of academic integrity and avoid plagiarism. It also ensures that the individuals responsible for the case study receive recognition for their work.
In summary, citing case studies is essential in academic writing to enhance credibility, facilitate further exploration, and acknowledge the original authors’ contributions.

Researchers in the behavioral and social sciences often use case studies to analyze new phenomena. The sixth edition of the "Publication Manual of the American Psychological Association" offers style and format guidelines for these writers. However, a case study does not have its own citation style. Instead, reference the book or journal that published the study.
After discussing a case study in text, include a reference citation within parentheses. Insert the author's last name, a comma and the date, such as (Doe, 1998). If you mention the author in text, omit the name.
Include in-text citations of case studies on the References page. For a book, begin with the author's last name, a comma, initials and a period. Put the publication date inside parentheses. Add a period. Insert the italicized title of the book in sentence case and a period. Conclude with the publication location, a colon, the publisher and a period;
for example: Doe, J. (1998). Psychological case studies. New York: Psych Books.
Put an in-text citation to a case study from an article on the References page. Start with the author's last name, a comma, initials and a period. Insert the year inside parentheses. Add a period. List the title of the article in sentence case followed by a period. Include the italicized title of the journal, a comma and volume number. Add a comma, the hyphenated page numbers and a period;

Usually, your institution (or the journal you’re submitting to) will require you to follow a specific citation style, so check your guidelines or ask your instructor.
In some cases, you may have to choose a citation style for yourself. Make sure to pick one style and use it consistently:
If in doubt, check with your instructor or read other papers from your field of study to see what style they follow.
In most styles, your citations consist of:
In-text citations most commonly take the form of parenthetical citations featuring the last name of the source’s author and its year of publication (aka author-date citations).
An alternative to this type of in-text citation is the system used in numerical citation styles , where a number is inserted into the text, corresponding to an entry in a numbered reference list.
There are also note citation styles , where you place your citations in either footnotes or endnotes . Since they’re not embedded in the text itself, these citations can provide more detail and sometimes aren’t accompanied by a full reference list or bibliography.
(London: John Murray, 1859), 510. |
A reference list (aka “Bibliography” or “Works Cited,” depending on the style) is where you provide full information on each of the sources you’ve cited in the text. It appears at the end of your paper, usually with a hanging indent applied to each entry.
The information included in reference entries is broadly similar, whatever citation style you’re using. For each source, you’ll typically include the:
The exact information included varies depending on the source type and the citation style. The order in which the information appears, and how you format it (e.g., capitalization, use of italics) also varies.
Most commonly, the entries in your reference list are alphabetized by author name. This allows the reader to easily find the relevant entry based on the author name in your in-text citation.
In numerical citation styles, the entries in your reference list are numbered, usually based on the order in which you cite them. The reader finds the right entry based on the number that appears in the text.
The AI-powered Citation Checker helps you avoid common mistakes such as:
Because each style has many small differences regarding things like italicization, capitalization , and punctuation , it can be difficult to get every detail right. Using a citation generator can save you a lot of time and effort.
Scribbr offers citation generators for both APA and MLA style. Both are quick, easy to use, and 100% free, with no ads and no registration required.
Just input a URL or DOI or add the source details manually, and the generator will automatically produce an in-text citation and reference entry in the correct format. You can save your reference list as you go and download it when you’re done, and even add annotations for an annotated bibliography .
Once you’ve prepared your citations, you might still be unsure if they’re correct and if you’ve used them appropriately in your text. This is where Scribbr’s other citation tools and services may come in handy:

Add a citation whenever you quote , paraphrase , or summarize information or ideas from a source. You should also give full source details in a bibliography or reference list at the end of your text.
The exact format of your citations depends on which citation style you are instructed to use. The most common styles are APA , MLA , and Chicago .
The abbreviation “ et al. ” (Latin for “and others”) is used to shorten citations of sources with multiple authors.
“Et al.” is used in APA in-text citations of sources with 3+ authors, e.g. (Smith et al., 2019). It is not used in APA reference entries .
Use “et al.” for 3+ authors in MLA in-text citations and Works Cited entries.
Use “et al.” for 4+ authors in a Chicago in-text citation , and for 10+ authors in a Chicago bibliography entry.
The Scribbr Citation Generator is developed using the open-source Citation Style Language (CSL) project and Frank Bennett’s citeproc-js . It’s the same technology used by dozens of other popular citation tools, including Mendeley and Zotero.

APA format is widely used by professionals, researchers, and students in the social and behavioral sciences, including fields like education, psychology, and business.
Be sure to check the guidelines of your university or the journal you want to be published in to double-check which style you should be using.
MLA Style is the second most used citation style (after APA ). It is mainly used by students and researchers in humanities fields such as literature, languages, and philosophy.

What do you study in your college? If you are a psychology, sociology, or anthropology student, we bet you might be familiar with what a case study is. This research method is used to study a certain person, group, or situation. In this guide from our dissertation writing service , you will learn how to write a case study professionally, from researching to citing sources properly. Also, we will explore different types of case studies and show you examples — so that you won’t have any other questions left.
A case study is a subcategory of research design which investigates problems and offers solutions. Case studies can range from academic research studies to corporate promotional tools trying to sell an idea—their scope is quite vast.
While research papers turn the reader’s attention to a certain problem, case studies go even further. Case study guidelines require students to pay attention to details, examining issues closely and in-depth using different research methods. For example, case studies may be used to examine court cases if you study Law, or a patient's health history if you study Medicine. Case studies are also used in Marketing, which are thorough, empirically supported analysis of a good or service's performance. Well-designed case studies can be valuable for prospective customers as they can identify and solve the potential customers pain point.
Case studies involve a lot of storytelling – they usually examine particular cases for a person or a group of people. This method of research is very helpful, as it is very practical and can give a lot of hands-on information. Most commonly, the length of the case study is about 500-900 words, which is much less than the length of an average research paper.
The structure of a case study is very similar to storytelling. It has a protagonist or main character, which in your case is actually a problem you are trying to solve. You can use the system of 3 Acts to make it a compelling story. It should have an introduction, rising action, a climax where transformation occurs, falling action, and a solution.
Here is a rough formula for you to use in your case study:
Problem (Act I): > Solution (Act II) > Result (Act III) > Conclusion.
The purpose of a case study is to provide detailed reports on an event, an institution, a place, future customers, or pretty much anything. There are a few common types of case study, but the type depends on the topic. The following are the most common domains where case studies are needed:

Let's look at the structure of an outline based on the issue of the alcoholic addiction of 30 people.
Introduction
After you’ve done your case study research and written the outline, it’s time to focus on the draft. In a draft, you have to develop and write your case study by using: the data which you collected throughout the research, interviews, and the analysis processes that were undertaken. Follow these rules for the draft:
📝 Step | 📌 Description |
---|---|
1. Draft Structure | 🖋️ Your draft should contain at least 4 sections: an introduction; a body where you should include background information, an explanation of why you decided to do this case study, and a presentation of your main findings; a conclusion where you present data; and references. |
2. Introduction | 📚 In the introduction, you should set the pace very clearly. You can even raise a question or quote someone you interviewed in the research phase. It must provide adequate background information on the topic. The background may include analyses of previous studies on your topic. Include the aim of your case here as well. Think of it as a thesis statement. The aim must describe the purpose of your work—presenting the issues that you want to tackle. Include background information, such as photos or videos you used when doing the research. |
3. Research Process | 🔍 Describe your unique research process, whether it was through interviews, observations, academic journals, etc. The next point includes providing the results of your research. Tell the audience what you found out. Why is this important, and what could be learned from it? Discuss the real implications of the problem and its significance in the world. |
4. Quotes and Data | 💬 Include quotes and data (such as findings, percentages, and awards). This will add a personal touch and better credibility to the case you present. Explain what results you find during your interviews in regards to the problem and how it developed. Also, write about solutions which have already been proposed by other people who have already written about this case. |
5. Offer Solutions | 💡 At the end of your case study, you should offer possible solutions, but don’t worry about solving them yourself. |
Even though your case study is a story, it should be based on evidence. Use as much data as possible to illustrate your point. Without the right data, your case study may appear weak and the readers may not be able to relate to your issue as much as they should. Let's see the examples from essay writing service :
With data: Alcoholism is affecting more than 14 million people in the USA, which makes it the third most common mental illness there. Without data: A lot of people suffer from alcoholism in the United States.
Try to include as many credible sources as possible. You may have terms or sources that could be hard for other cultures to understand. If this is the case, you should include them in the appendix or Notes for the Instructor or Professor.
After you finish drafting your case study, polish it up by answering these ‘ask yourself’ questions and think about how to end your case study:

What are psychological theories.
Psychological theories are systematic explanations of human mental processes and behaviors, developed through both empirical research and field observation. These theories provide frameworks for understanding how and why people think, feel, and act the way they do, and guide both academic research and practical applications in areas like therapy, education, marketing, and public policy.

If you’ve ever snoozed your alarm and then been late to work or school, you may look back and ask yourself: why did I do that? Maybe your bus driver saw you running for the bus and chose to keep on driving, and you ask yourself: what was going through his mind? Or maybe the day turned out okay, because you came home to your loving partner, and you thought to yourself: why am I so compatible with this person but not others? To begin unpacking these questions and more, we can turn to psychological theories to help us understand ourselves and the people around us.
Psychological theories are systematic frameworks for understanding, predicting, and explaining human behavior and mental processes. These theories include everything from cognitive theories , which focus on mental processes such as perception and memory, to behavioral theories , which examine the relationship between stimuli and responses. Although there are many ways to explain how and why we are the way we are, it is the constant testing and refining of different psychological theories that guides research and helps us to consistently improve our understanding of humans—both within academia and beyond.
The world makes much less sense than you think. The coherence comes mostly from the way your mind works. – Daniel Kahneman
Cognition: Mental processes involved in gaining knowledge and comprehension, including thinking, knowing, remembering, judging, and problem-solving.
Psychoanalysis: A therapy developed aimed at exploring the unconscious mind to understand and treat psychological disorders.
Positive Reinforcement : In behaviorism, the process of encouraging or establishing a pattern of behavior by offering a reward when the desired behavior is exhibited.
Montessori Method: An educational approach developed by Dr. Maria Montessori that emphasizes self-directed learning, hands-on activities, creativity, and a love for learning and collaborative play in a child-centered environment.
Herzberg's Motivation Theory: Also known as the two-factor theory, this theory proposes that job satisfaction is influenced by two distinct sets of factors: hygiene factors and motivator factors. Hygiene factors pertain to external conditions such as the workplace environment and salary, while motivator factors are typically intangible elements like receiving recognition or opportunities for personal growth.
As long as there have been humans, there have been questions about why we think and act the way we do. There have likely been countless theories developed throughout time that we have no written record of, such as those developed by native peoples. For many, the known history of psychological theories goes back to ancient philosophical inquiries about the human mind and behavior. Early thinkers like Plato and Aristotle laid the groundwork for understanding the mind's complexities, focusing on issues of perception, memory, and motivation. Hundreds of years later, the 17th century marked a significant shift with the rise of empiricism, championed by philosophers like John Locke who proposed that knowledge is derived from sensory experience. This idea laid the foundation for later psychological theories that emphasize the role of the environment in shaping behavior. 1
The formal birth of psychology as a scientific discipline is often credited to Wilhelm Wundt, who established the first psychology laboratory in Leipzig, Germany, in 1879. Wundt's work marked the beginning of experimental psychology, where he used introspection to explore the structure of the conscious mind. His approach, known as structuralism, aimed to break down mental processes into their most basic components. Around the same time, William James in the United States was developing his own approach called functionalism, which focused on the purpose of consciousness and behavior in helping individuals adapt to their environment. These early schools of thought laid the groundwork for more complex psychological theories. 1
The early 20th century saw the emergence of several influential psychological theories that have shaped the field as we know it today. Sigmund Freud's psychoanalytic theory introduced the idea of the unconscious mind and the role of early childhood experiences in shaping personality (he’s the guy who you usually picture talking to a patient while they lay on a couch, discovering a repressed memory). While Freud's ideas were revolutionary, they were (and still are) controversial, spurring the development of alternative theories. Behaviorism, led by John Watson and later B.F. Skinner, rejected the introspective methods of the past and focused instead on observable behavior, emphasizing the role of environmental stimuli in shaping actions. Behaviorism dominated psychology from the 1920s to the 1950s, particularly in the United States, influencing everything from education to advertising. 1
Toward the mid-20th century emerged a cognitive revolution, as cognitive psychologists began challenging the behaviorist movement by reintroducing the importance of mental processes. Pioneers like Jean Piaget and Noam Chomsky argued that studying internal cognitive processes (like thinking, memory, and language) was crucial for a complete understanding of behavior. This shift led to the development of cognitive psychology, which remains one of the most prominent areas of the field today. Additionally, humanistic psychology, which was considered more of a ‘counter-movement’ to behaviorism, emerged during this time, with figures like Carl Rogers and Abraham Maslow emphasizing personal growth, self-actualization, and the inherent goodness of people. All of these diverse perspectives have contributed to a more comprehensive and multifaceted understanding of human behavior, continuing to influence psychological research and practice today. 2

The impact of psychological theories extends far beyond academic research; scientifically understanding our own thoughts and behavior has influenced almost all aspects of modern life, shaping practices in education, marketing, public policy, and business.
In the realm of education, psychological theories have revolutionized teaching and learning methodologies. For example, certain developmental theories have provided educators with insights into how children think and learn at different stages. Jean Piaget’s theory of cognitive development suggests that children progress through specific stages of cognitive growth, with each stage characterized by distinct thinking patterns. 3 Understanding these stages allows teachers to adjust their teaching strategies to better match the cognitive capacity of their students.
Meanwhile, Lev Vygotsky’s concept of the zone of proximal development explains the gap between what a student can learn on their own versus with help. This theory posits that the role of education is to provide children with experiences that are in their proximal development stage, encouraging and advancing individual learning through social interaction. Students can solve problems independently, applying knowledge from conversations with peers and teachers to gradually develop the skills to perform tasks without direct help. 4 Understanding this theory has helped shape the role of teachers in the classroom; sometimes, it’s more about putting students in a situation where they can teach themselves to succeed rather than being explicitly taught.
For better or worse, psychological theories have also left a huge mark on the field of marketing and consumer behavior. Behaviorism, with its focus on conditioning and reinforcement, has been particularly influential in understanding and shaping consumer habits. Marketers have applied principles of operant conditioning to design reward systems—like loyalty programs or memberships—that encourage repeat purchases by reinforcing desired behaviors. The understanding of cognitive biases, such as the availability heuristic and the framing effect , has also allowed many marketers to craft persuasive messages that influence buyer decision-making. All of these psychological insights have helped businesses increase sales and foster brand loyalty—potentially misleading or even taking advantage of customers.
Public policy is another major area where psychological theories have had significant consequences. Understanding human behavior has helped policymakers create more effective campaigns to improve public health, environmental protection, education systems, and programs that better address social issues such as poverty and crime. The application of small interventions that capitalize on our biases in a nonrestrictive way (often referred to as “ nudging ”), has gained prominence in recent years. This approach, popularized by Richard Thaler and Cass Sunstein, is based on the idea that small changes in the way choices are presented can have a substantial impact on behavior, like automatically enrolling employees in retirement savings plans, with the option to opt-out. A change as simple as this has been shown to dramatically increase participation rates in retirement plans.
If you’re in a traditional workplace, you may have experienced the influence of psychological theories in your office without realizing it. Organizational behavior and human resource management have been hugely shaped by Maslow’s hierarchy of needs and Herzberg’s two-factor theory. Both of these theories have changed how companies understand and manage employee motivation and satisfaction. Maslow’s theory suggests that employees (and all humans) are motivated by a hierarchy of needs, starting with basic physiological needs like food and water and progressing to self-actualization. Thus, companies that recognize and address these needs by providing a safe working environment, opportunities for social interaction, and chances for personal growth, are more likely to foster a motivated and productive workforce (perhaps this is why having free coffee and snacks in the office is so motivating?). Herzberg’s two-factor theory, which distinguishes between hygiene factors (e.g., salary, work conditions) and motivators (e.g., recognition, achievement), has also guided organizations in designing jobs and work environments to maximize employee satisfaction.
Psychological theories, while important to our understanding of human behavior, are theories, not facts. We can still only speculate and make educated guesses as to how and why our brains function the way they do. Many of the theories we’ve previously developed haven’t withstood the test of time, or at least not without serious criticism.
One of the most contentious figures in psychology is Freud, whose psychoanalytic theory has faced huge criticism. Although Freud's focus on the unconscious mind and his theories of psychosexual development were groundbreaking at the time, they were also largely unscientific and overly deterministic. Critics argue that many of Freud’s ideas, such as the Oedipus complex (briefly, that boys are repressing attraction to their moms and jealousy of their fathers’ genitals) and the emphasis on sexual drives, lack empirical support and are difficult if not impossible to test systematically. His theories have also been accused of being culturally biased, reflecting the patriarchal and sexually repressive values of his time, which are largely not applicable (or at least hopefully less so) today.
Behaviorism, another major psychological theory, has also faced significant criticism, particularly for its reductionist approach. Watson and Skinner’s theory focuses exclusively on observable external behaviors and their environmental conditioning, largely ignoring the importance of internal mental processes like emotion. To no surprise, humans have a lot going on under the surface, and not taking this into account can be problematic. That’s because we are much more than machines reacting directly to the environment around us, and internal or unobservable processes (like our preferences, hunger, hormones, and social upbringing) can have dramatic influences on the way we react to stimuli. This critique helped propel the cognitive revolution to take into account the other missing piece of the puzzle: the mind.
Enter cognitive psychology, which has also been criticized for its heavy reliance on computational models of the mind, which can oversimplify the complexities of human cognition—after all, the brain is not a computer. Since these models usually compare the mind to a computer processing information, they’ve also been accused of neglecting the emotional, social, and cultural factors that influence thought and behavior. Thus, cognitive psychology, just like behaviorism before it, tends to focus on “universal” principles—when, of course, there are huge individual differences among people, places, and cultures.
Humanistic psychology emerged as a response to both behaviorism and psychoanalysis to introduce a more optimistic view of human nature—but hasn’t escaped its share of criticisms. While prominent figures like Rogers and Maslow emphasized the potential for personal growth and self-actualization, proposing that people are inherently good and capable of achieving their full potential, many critics argue that this perspective is overly idealistic. Much like Freud’s psychoanalysis, it can be incredibly hard to test humanistic psychology empirically which can make it even harder to find acceptance from the scientific community. Also, due to the focus on the individual’s growth and self-fulfillment, it can be easy to overlook the social and structural factors that limit personal development; essentially, the individual is responsible for their own shortcomings or inadequacies, ignoring systemic issues like poverty, discrimination, and lack of access to education.
Much of the existing psychology research is on a WEIRD (Western, Educated, Industrialized, Rich, and Democratic) population, which has raised concerns about the generalizability of its findings to non-WEIRD populations. All theories involve some sort of bias, and no population will ever be truly representative. The role of psychological theories in perpetuating or challenging societal norms is a controversial subject because, while the field has contributed to understanding and reducing prejudice, critics argue that some research in social psychology specifically can inadvertently reinforce stereotypes or fail to account for cultural and contextual differences.
For example, the application of Maslow’s hierarchy of needs discussed earlier posits that individuals prioritize their needs in a specific order, starting with basic physiological needs and moving up through safety, love and belonging, esteem, and self-actualization. This model aligns well with WEIRD cultures, which tend to emphasize individualism and personal achievement since cultural values prioritize personal growth and self-fulfillment. However, in more collectivist cultures, where community, family, and social harmony are often prioritized over individual needs, Maslow’s hierarchy doesn’t fit quite as well. In addition, studies that categorize people into rigid social groups based on race, gender, or socioeconomic status may unintentionally perpetuate the very biases they aim to study. These critiques have led to a growing recognition of the need for more culturally sensitive research and a broader, more inclusive approach to studying behavior.
Behavioral psychology—particularly the principles of operant conditioning—has been instrumental in shaping modern educational practices. Operant conditioning, a theory developed by Skinner, posits that behavior is influenced by the consequences that follow it. Specifically, reinforcement increases the likelihood of a behavior being repeated, while punishment decreases it. This approach can be applied to classroom management when teachers try to promote positive behavior that leads to academic achievement.
For instance, many schools implement reward systems like tokens or points that use positive reinforcement to encourage good behavior like completing homework on time, participating in class discussions, or staying silent during reading times. Usually, these tokens are traded in for rewards like extra recess time, which can help keep kids motivated. We can also see how punishment systems like detention or extra homework can be used to discourage unwanted or disruptive behavior. All of these systems are designed based on our understanding of different psychological theories, from how we best learn to which tools are appropriate for which ages, and have informed interventions for students with special needs, behavioral disorders, or learning disabilities.
The Montessori Method is an educational approach that is based on principles from Piaget’s developmental psychology and Vygotsky’s zone of proximal learning principles. Montessori classrooms emphasize self-directed learning, hands-on activities, and collaborative play, giving kids the chance to explore their environment at their own pace and in their own way. Educational materials are designed to support the children’s developmental stages and foster independence, curiosity, and a love of learning: key components of the developmental theory.
One of the most direct applications of psychological theories is in the field of clinical psychology, where theories of human behavior and mental processes have informed the development of many therapeutic techniques. For example, many people are familiar with cognitive-behavioral therapy (CBT) , as it’s one of the most widely used therapeutic approaches today. This type of therapy is grounded in cognitive theory by helping individuals identify and change distorted thinking patterns that lead to negative emotions and behaviors. This theory-based approach has proven effective in treating a variety of psychological disorders, including depression, anxiety, and PTSD. 5
Understanding psychological theories is crucial for developing effective therapeutic approaches to provide the foundational knowledge needed to comprehend complex mechanisms underlying mental health issues. These theories can offer structured frameworks that guide therapists in assessing, diagnosing, and treating various psychological conditions and help them address the specific needs of individuals. Since so much of the work is built on tested theory, treatment can be both scientifically grounded and practically effective.
How might behavioral science transform education.
With so much discussion about the impact of psychological theories on education, it’s important to understand some of the biggest challenges in education reform and how they can be improved.
Another important application is looking at how we use psychological theory to shape our financial decisions, and how banks use these same understandings for themselves.

Traditional rondavel building patterns, designs and materials have changed due to urbanisation, economic status, globalisation, and modernisation. There is limited understanding of how the architectural change has impacted the utilisation of rondavel space. This study uses the concept of habitus to understand whether the changing design of traditional rondavels has influenced their utilisation, based on a case study of the Mbhashe Local Municipality in the Eastern Cape province, South Africa. The data was collected using semi-structured interviews. The findings reveal the habitus of the AmaXhosa people on how they utilise traditional rondavels (family house) for childbirth, placing a deceased’s coffin, sleeping, seating, food preparation, serving and storage, keeping the spear, hosting ceremonies, communicating with ancestors, and interacting with the living. While the influence of contemporary architecture has changed the construction of rondavels, the inhabitants have not resisted changes to the architecture or cultural values as they have found different ways to adapt. Certain old dispositions are adaptable to contemporary structures, but some people are uninterested in adapting elements to the contemporary rondavel. Some habits of utilising traditional rondavels cannot be adapted to the contemporary rondavel because of health and medical innovations.
Introduction.
Based on archaeological evidence, rondavels have existed since pre-colonial times as a prime settlement form in homesteads in much of South Africa and other African countries, including Botswana, Kenya, Lesotho and Eswatini (Schoenauer 2000 ; Steyn 2006 ). The rondavel is considered as a vernacular architecture: it is built using locally sourced material and forms part of a region’s culture and heritage (OpenHeritage 2016 ). Steyn ( 2006 :1) describes the rondavel as a “drum”, often built with mud and grass-thatched roofs (Fig. 1A ). They are popular indigenous settlements which are still prevalent in the rural areas. While most households have more than one rondavels (Fig. 1B ), some indigenous settlements are now roofed with zinc materials (Fig. 1B ). Going forward, this article refers to indigenous settlements as traditional rondavels.

Traditional rondavels were used for dwelling and hosting important customary rituals and celebrations in Africa (Steyn 2006 ). Modern day rondavels exist with flat-roofed rectangular buildings or structures built using cement and zinc roofs, which will be referred to as contemporary rondavel design henceforth (Van Vuuren 2017 ).
Steyn ( 2006 ) argues that the change is a result of urbanisation and economic status because people admire urban architecture and can afford their desired building materials. A study by Aikpehae et al. ( 2016 ) reveals that globalisation, urbanisation and modernisation transformed building patterns, designs and materials used for construction. They illustrate how Nigerian building patterns and housing have transformed because of the influence of colonisation (Aikpehae et al. 2016 ). Guerrieri ( 2020 ) adds that migration has allowed the export of architecture and urban planning models from one country to another; hence, we see the same style across countries. The global intercultural contact led to the change in dwellings in southern Africa (Frescura 1981 , 2015 ) where traditional dwellings were constructed using mud, wattle and thatch grass. Missionaries introduced contemporary building constructed using sun brick and mortar with corrugated iron sheet for roofing as well as highveld and parapet housing styles, the contemporary building is illustrated in Fig. 2 .

Tapiero et al. ( 2024 ) indicates that in Montesinho Natural Park, north-east of Portugal, residents had vernacular buildings constructed using locally available wood, slate stone tiles, lime mortar, schist and granite. The availability of industrialised material and decreasing traditional labour posed a threat vernacular buildings.
The following section discusses the evolution of the traditional and modern rondavel followed by the utilisation of rondavels by amaXhosa people, detailing the study area, research methods, results, discussion and conclusion.
Early African dwellings were caves, stone-walled iron shelters or houses quickly erected and dismantled as nomadic societies followed herds of animals (Frescura, 1981 ; Moremoholo, 2021 ). Frescura ( 1981 ) explains the historical development of dwelling types, presented in Fig. 3 . The earliest traditional dwelling was a beehive hut also known as ngqu-phantsi . It was made up of stakes organised in a circle with their tops arched inward to a point. The stakes were then bound together by hoops and the frame was insulated with thatched grass (Walton, 1949 ). It is possible that the need for more living space resulted in the rondavel, which is a cone-on-cylinder rondavel with a wall and roof. Although its doorway was raised higher compared to the beehive hut, it was still lower than the height of a man. The material used to construct traditional rondavel was either a thatch roof with stones and mud bricks or sticks mixed clay and dung mortar or mud and wattle (Walton 1949 ; Frescura 1981 ; Oliver 2006 ; Moremoholo 2021 ; Onyejegbu et al. 2023 ). These vernacular dwellings were constructed using locally available materials (Tapiero et al. 2024 ).

The third iteration of dwelling development was influenced by Western ideas of hipped-on-cone, which had a linear floor plan, rooms divided into rows and triangulation of the thatch roof. The fourth dwelling type was an introduction of the highveld style with iron-sheet roofing and sun brick (Frescura 1981 ).
Western ideas influenced the cone-on-cylinder rondavel design and materials used which included the use of iron-sheet roofing and sun brick. Despite the Western influences, the traditional rondavel still exists while others have modernised (Moremoholo 2021 ; Onyejegbu et al. 2023 ). Vellinga ( 2006 ) notes that the traditional vernacular architecture has not vanished, but has rather merged with modern styles to suit the current circumstances. Tapiero et al. ( 2024 ) argue that the use of modern materials in construction does not compromise the values of the dwelling in the community. They also note that conserving vernacular architecture plays an essential role in the preservation of culture and sustainable practises by optimising energy usage (Tapiero et al. 2024 ). Onyejegbu et al. ( 2023 ) argue that some Nigerian households still have traditional mud huts that were built by their forefathers in commemoration of their culture, tradition and prowess.
Moremoholo ( 2021 ) used a case study of the Sotho community in Makgabeng, a rural area in Limpopo to investigate how indigenous values have been incorporated or retained on houses built using brick and mortar. The findings show that both traditional rondavel and modern dwellings exist and residents were able to adapt values of indigenous rondavel to modern dwellings, including practising ancestral ceremonies.
Smith ( 2022 ) suggests that the modernisation of the traditional rondavel design into contemporary sensibilities reflects the development of awareness of the diverse heritage that connects South Africa to the rest of the African continent and its people. Thus, the integration and adaptation of indigenous values into modernisation promotes self-definition for many South Africans. Moreover, it encourages a deeper appreciation of the connections between South Africa and the rest of the world. Bianco ( 2022 ) states that this hybrid form of building reflects the evolution of local culture and ways of life so that one can imagine new development aspects entrenched in the culture and environment (Bianco 2022 ). Thus, currently, vernacular architecture can be understood as the foundation of the contemporary architectural type that is rooted in integrating local building traditions (Naude 2010 ; Bianco 2022 ). The current study focuses on the amaXhosa people and intends to understand whether the changing design of traditional rondavels has influenced their utilisation.
The amaXhosa people are predominantly located in the Eastern Cape province (Nyamende 1994 ; Mokhoathi 2021 ). A rondavel in a Xhosa home ( umzi ) typically exists in a cluster of other structures. Umzi , plural imizi , is a collection of physical, social and organic elements constituting a settlement component known as homestead. It typically comprises several rondavels or huts (the family house, with middle huts reserved for children and visitors as well as a traditional dispensary and consultation), an adjacent garden and a kraal with tools and equipment often used in various ways (Perry 2013 ).
The family house ( indlu enkulu ) is the main hut where everyone meets to socialise and prepare, store and eat food (McAllister 2004 ). It is a space where all rituals take place and people communicate with their ancestors (McAllister 2004 ; Mlisa 2009 ). In the past, following the birth of a child in the family house, children and men were prohibited from using the space (Kobo 2016 ). McAllister ( 2004 ) illustrates how the family house is divided, as shown in Fig. 4 .
This figure was reproduced with permission: Ethnology, Department of Anthropology at the University of Pittsburgh.
The upper part, called entla , is associated with ancestors; an appointed person will commune with the ancestors, and it serves a storage space for meat and beer if there is a ritual planned (McAllister 2004 ; Reeve 2011 ). The right side is the sitting area for men while the left is reserved women. Older people sit next to the door on either side, while the youngest generation often sits next to the upper part of the rondavel (McAllister 2004 ). At the centre is a hearth ( eziko ), where they make fire for cooking (McAllister, 2004 ; Brocious 2021 ). Kobo ( 2016 ) identifies the hearth as a pedagogical space for the girl child to learn food preparation. The way the amaXhosa people utilise the traditional family house can be purported as a gendered space.
A gendered space is “…more attractive for women than for men; men and women use the same space in different ways: some spaces give feelings of comfort and belonging to men, while women feel excluded; in some spaces, women have authority, while other spaces are under male authority” (Fortuijn et al. 2004 : 215). This is a gendered space because of how a spatial order of seating and gender roles in the utilisation of the space is enforced (McAllister 2004 ; Kobo 2016 ).
It should be noted that the number of rondavels in a homestead depends on the family’s needs. In addition to the family house, a rondavel may be reserved as a bedroom for younger family members and to accommodate visitors (Mlisa 2009 ). Moreover, a rondavel may be used by traditional healers for consultations and storing dispensary (umrawule) items. Certain people are often excluded from using such a space. Menstruating women are prohibited from accessing this space while on their cycle because of a belief that they will defile the herbs (Mlisa, 2009 ). The dispensary is only built once a rondavel has been revealed to a potential traditional healer in a dream, and a ritual is performed to officially open the rondavel and the dispensary prior to consultations being held (Mlisa, 2009 ).
Literature is ambiguous as to whether the recorded rondavel uses are performed in traditional or contemporary rondavels and whether the uses are adaptable to current rondavel designs (McAllister 2004 ; Mlisa 2009 ; Perry 2013 ; Kobo 2016 ; Brocious 2021 ). The available literature focuses on understanding traditional rondavel architecture, its utilisation, history and the changes in the design and structure (Schoenauer 2000 ; Steyn 2006 ). Vellinga ( 2006 ) also notes that publications on vernacular architecture are rarely featured and those that are available focus on drawings, forms and material. The impact of changing building designs and structures in traditional space utilisation is inadequately understood. It is against this backdrop that this study uses the concept of habitus to understand whether the changing design and structure of rondavels has influenced the traditional utilisation of rondavel spaces, based on a case study of the Mbhashe Local Municipality in the Eastern Cape province of South Africa.
Pierre Bourdieu, a French sociologist who was concerned with what motivates social action and behaviour (Navarro 2006 ), developed the concept of habitus, which refers to the norms, values, habits, dispositions and behaviour of a particular group. Each society has its own habitus. Habitus can then guide how a particular group feels, thinks, acts and uses the space (Bourdieu et al. 2000 ; Navarro 2006 ). Habitus can be a product of past experiences and practices learned from parents, family experiences, and society (Hong and Zhao 2015 ). It is created and reproduced by the structures and practices of society (Bourdieu et al. 2000 ; Navarro 2006 ). People with similar backgrounds (social class, religion, nationality, ethnicity, education and profession) usually share habitus which shapes how individuals perceive or receive the world. It is not fixed; it changes due to circumstances (Bourdieu et al. 2000 ; Navarro 2006 ). However, when change occurs, some within the group may resist the change while others adapt to a new style of doing things. Often, others combine the traits of new and old habitus. Therefore, the theory seeks to provide an in-depth understanding of how people adapt in a changing world and circumstances resulting to change.
Bourdieu used this concept to study how the Algerian habitus changed during the liberation struggle in the 1950s (Bourdieu et al. 2000 ; Navarro 2006 ). He analysed their norms, values, habits, dispositions and behaviour before and after colonisation. He defined Algerian peasantry as a traditional society which believed in:
the importance of group solidarity;
kinship based on patriarchal and patrilineal relationships;
patriarchal division of labour;
marriage as the primary concern of the family; and
an economy governed by pre-capitalist methods such as
subsistence farming,
products not sold but shared by the community
goods exchanged for social capital (i.e. a neighbour will lend you an ox in exchange for fresh produce).
The economy was governed by strict reciprocity and non-payment. The blacksmith was expected to provide each peasantry with all repairs in exchange for goods and services (Bourdieu et al. 2000 ; Navarro 2006 ). Their habitus was passed from generation to generation. As determined by Bourdieu, habitus changes over time due to circumstances. The change in the Algerian habitus was a result of French colonial imposition which introduced a capitalist economy leading to a decline in agricultural activities and the establishment of factories in urban areas (Bourdieu et al. 2000 ; Navarro 2006 ). Due to this increased urbanisation, people started working for wages, which resulted in the development of social classes (Bourdieu et al. 2000 ; Navarro 2006 ). Subsequently, women were granted access to receiving an education and earning a living. Likewise, society was introduced to the concept of bachelorhood, with marriage being an individual choice. Communal living with neighbours sharing their fresh produce evolved into neighbours selling their produce for cash (Bourdieu et al. 2000 ; Navarro 2006 ). Ultimately, the culture of group solidarity was destroyed, and the focus was on individualism.
Bourdieu argues that change can be adopted or resisted, as evidenced in Algeria (Bourdieu et al. 2000 ; Navarro 2006 ). Certain Algerian norms, values, habits, dispositions and behaviours were influenced by innate traditions of peasantry and colonial imposition (Bourdieu et al. 2000 ; Navarro 2006 ). Most older people resisted the change and continued to be trapped in the old way of life.
This study focuses on the traditional family house rondavel with the users’ social activities derived from the norms, values, habits, dispositions and behaviours of amaXhosa. Premised on the concept of habitus used by Bourdieu et al. ( 2000 ) and Navarro ( 2006 ) in the analysis of Algerian peasantry, this study unpacks the utilisation of the traditional family house rondavel before the introduction of contemporary architecture and design changes. Before the introduction of the contemporary architecture, the traditional family house rondavel was spatially divided based on gender and used for childbirth, communicating with ancestors and hosting rituals, serving and storing food and igniting a fire for warmth (McAllister 2004 ; Kobo 2016 ; Brocious 2021 ). This paper intends to understand whether the changing design and structure of rondavels has influenced its utilisation, using the case of Mbhashe Local Municipality.
The Mbhashe Local Municipality extends over a geographic area of over 3200 km² and is situated within the Amathole District Municipality in the Eastern Cape Province, South Africa (Mbhashe Local Municipality IDP, 2016 ; 2023 a). The municipality is named after the Mbhashe River, which tracks between the municipality’s major urban regions of Willowvale (Gatyane), Xhorha and Dutywa, the latter being the administrative centre or municipal headquarters. The municipality has a total population of approximately 240 020 people (Municipalities of South Africa 2023 ), 94% of whom speak the isiXhosa language (Mbhashe Local Municipality IDP, 2016 ; 2023 b). It is a rural region facing various challenges, including poor road infrastructure, high unemployment and inadequate access to essential services such as water and electricity (Mbhashe Local Municipality IDP, 2016 ; 2023 a). It finds significant economic leverage from tourism nodes through coastal, inland and historic or heritage site attractions.
Rondavel structures are prominent in every homestead. Over 66% of households in the municipality are traditional dwellings Footnote 1 , followed by 21 and 5% of households living in brick or concrete block structures and flat blocks, respectively (Mbhashe Local Municipality IDP, 2021 ). However, some households have a modernised rondavel and, more commonly, an octagonal-shape veranda structure, sometimes with an attached garage. Others tend not to have a rondavel at all albeit infrequently. In rural areas, the process of domestic building is not influenced by planning schemes and policies (Oliver 2006 ). Instead, rural architecture is enriched by the surrounding natural environment, local economy and livelihood of villagers (Pirzad and Moghaddam 2023 ). This offers villagers free will to build the type and design of house they desire.

The points of interest indicated in the map are examples of homesteads and places across the municipality where:

A map representing a study area—Mbhashe Local Municipality.
Ethical clearance was received from Rhodes University. Purposive sampling was used to select a sample population, which included participants of amaXhosa descent with a rondavel structure in their homesteads and residing within the Mbhashe Local Municipality. Ten participants, aged 24–48 years old, were interviewed; they are referred to as Participants 1 to 10 (P01–P10).
Data was collected using participatory mapping and semi-structured interviews consisting of open-ended questions. The interview schedule was developed with a purpose of obtaining an in-depth understanding of the utilisation of rondavels and changes that occurred over time because of the new architectural style. The interviews were conducted face-to-face at the participants’ residences. The participants were also given a rondavel diagram to illustrate the spatial ordering of how the rondavel family house was utilised in the Mbhashe Local Municipality. The results are presented in Fig. 6 .
Spatial ordering of how the amaXhosa family house rondavel was utilized in the Mbhashe Municipality.
The information from the participants' drawings were then used to create Fig. 6 diagram, which was constructed using ArcMap 10.7.1 software for visualisation of the activities undertaken in the family house. The circle represents a typical rondavel floorplan with a diameter of 6 m (3 m radius). The diameter of the rondavel intersects the doorway and therefore dictates the gendered sides. The points in the diagram do not represent actual geometric values, instead they are ordinal representations of circular living in the AmaXhosa family house. Data was analysed and presented using thematic analysis. The concept of habitus guided the development of the themes presented. The first theme related to the amaXhosa habitus and the utilisation of traditional rondavels in the Mbhashe Local Municipality and the second was the amaXhosa habitus and the changing rondavel design in the Mbhashe Local Municipality
In both themes, specialised quotations to highlight some pertinent statements and demonstrate how the participants make sense of the rondavels and their utilisation, using their exact words.
The section of findings only focus on the traditional family house rondavel before the introduction of the contemporary architecture. Adapted from McAllister ( 2004 ), the participants were given a circle to explain the use of each space and its purpose. They also revealed some uses that were not presented in earlier sections. First, the spatial division of the family house based on gender was discussed, followed by how the Mbhashe people utilised the family house. Figure 6 illustrates the spatial division between men (right) and women (left) inside the family house. Women married into the family ( makoti ) are forbidden to access the men’s side. The mud bench, known as soze , is built on the men’s side by the door for seating.
Women sit on the floor on handcrafted mats woven from reeds or grass known as ikhukho . Behind the door on the women’s side is a place for childbirth. The participants also alluded to the statement made by Kobo ( 2016 ) that during the birthing process, children and men are prohibited from using the space. They revealed that there was no cultural significance in giving birth at home. Instead, the inaccessibility of health facilities necessitated home births. Booysen ( 2003 ) argues that, in South African rural areas, women give birth at home because health facilities are located remotely to the homesteads and they do not have the means to access them.
Regarding funeral rites, the deceased’s coffin will arrive at the homestead the day before the funeral and a night vigil – a ceremony to honour the deceased—will be held in the family house. The coffin is usually placed on the women’s side and senior women will gather to sleep next to the coffin until the funeral. An elderly family member will burn impepho (incense) and request the ancestors to welcome the deceased. It is believed that if this ritual is not performed, the deceased will not rest in peace.
In households that use the family house for sleeping, designated spaces will be allocated for men and women. A handcrafted mat is used as a base for the foam mattress on both sides. The seating arrangement in the family house is based on seniority, with younger members of the household placed toward the upper layer, as noted by McAllister ( 2004 ). The participants further explained that seniority was not based on age: married women were regarded as senior and women who were not related by blood or matrimony would occupy the upper end of the women’s side. Men’s seating arrangements depend on when one was initiated, with the youngest (the last to go to the bush) towards the upper layer.
McAllister ( 2004 ) and Reeve ( 2011 ) reveal that an appointed person will commune with the ancestors, and store meat and beer in the upper part of the rondavel if there is a ritual. Their findings concur with how the Mbhashe people utilise the space, further indicating that the upper layer is divided into A and B, as shown in Fig. 6 . On the right (men’s side) is where slaughtered meat and beer is stored. It is the responsibility of the men to serve both the meat and beer; hence, it is located on their side. Section B in Fig. 6 is a space in the uppermost end of the rondavel on the women’s side. It contains domestic essentials such as a table and cupboard, crockery, and cutlery and ilitye lokuguba , which is a flat rock which is used to grind food.
In the centre of the family house is a hearth. Kobo ( 2016 ) argues that this is where women are taught to prepare food. The findings of this study also reveal that men also use the space to roast corn. So, there are no gender-based restrictions on the use of this space. The centre also has a pole called intsika , which supports the roof structure. The door is positioned in the lower part of the family house. Section C, illustrated in Fig. 6 , is where the spear ( umkhonto) is kept by sticking it on the roof above the doorway on the men’s side. The spear is used for the slaughter of traditional animals if there is a ritual or ceremony. The spear is believed to obstruct lightning during a storm and is placed in the doorway.
The participants also utilised the rondavel for interacting with each other and the ancestors. Interaction takes place through song and dance during ceremonies. People also interact through spoken word to communicate with or appease ancestors, to socialize with each other by telling stories of love, horror, fiction, and the past, and to play games. The study’s participants expressed clearly how the family house is used which they learned from growing up in rural areas and passed from generation to generation. They have the duty to continue passing this information to the younger members of the family.
People in the rural areas of the Mbhashe Local Municipality were inclined to architectural change and desire contemporary architecture and luxury, including those who did not currently own it. The contemporary rondavel design was considered progressive, cognisant of the times and, for that matter, the contemporary way of life to which there was a strong inclination to conform: “I too [wish to have a modern house] because these are the houses that are built nowadays, and they make the home beautiful” (P 01).
Notwithstanding, there was a strong consensus to preserve conventional ways of using space and adapt to the contemporary design, including the structure and shape (multi-room), the material used (no longer a thatched roof or mud walls), or hard surfaces (tiles/concrete). The respondents preferred contemporary structures because of their aesthetic and convenience: “…contemporary houses have better aesthetical value, spacious and are functional (e.g., energy consumption, natural lighting)” ( P 09).
Other uses were not adopted in the contemporary house design such as utilising the family house for childbirth because modern women mostly give birth in hospitals and clinics. Statistics South Africa ( 2020 ) revealed that the number of home deliveries has decreased from 14% in 1998 to 4% in 2016 while health facility deliveries have increased from 83.4% in 1998 to 96.7% in 2016 (Statistics South Africa 2020 ). Both 1998 and 2016 home deliveries statistics are indicative of the national level (Statistics South Africa 2020 ).
Placing the deceased’s coffin in the upper part of the family house (section B in Fig. 6 ) was adopted in contemporary rondavel utilisation until the Covid-19 pandemic when people became sceptical of disease transmission. Before the pandemic, the deceased’s body would arrive at home a day before burial, and people would gather for a final ceremony the night before the funeral (night vigil) inside the family house to honour the deceased (Bambalele 2020 ). A South African Covid-19 restriction prohibited corpses being sent home prior to the funeral and the hosting of night vigils (Bambalele 2020 ). This practice has continued since Covid-19 restrictions were relaxed, while others have stopped. However, once the deceased’s coffin arrives on the funeral day, it is taken to the upper part of the family house and a ritual will still be performed where incense is burnt and a request is made to the ancestors to welcome the deceased. Therefore, the cultural significance of the whole process does not rest with the placement of the deceased’s body a day before the funeral but the performance of the ritual.
The presence of mud benches on the men’s side no longer exists. Although the traditional rondavel structure is diminishing in the physical environment, modernisation has certainly swayed people’s sense of feeling, thinking, acting and their use of space. Admittedly, modernisation has not entirely appropriated the Xhosa people’s habitus. Some people were uninterested in adapting to some elements of the contemporary rondavel and house design: “A traditional rondavel must be present in a home. You can make fire, but it is difficult to do that on floor tiles. Still, you perform customs in traditional rondavel” (P 03).
These people continue to use traditional rondavels for the above purposes while also adapting the contemporary rondavel or house design for other uses such as sleeping, unless there is a ceremony when there is no space: “ People do not want to sleep on the floor in the rondavel, and there is no privacy and tile, or cemented floor is cold” (P 04).
While other participants preferred to continue performing traditional ceremonies and communicating with ancestors in the traditional rondavel structure, there were respondents who were open to communicating with ancestors and interacting with the living, and divide space based on gender in the contemporary rondavel – as indicated in Fig. 6 . The cultural strongholds continued to be practiced regardless of the house structure. Therefore, in the absence of a traditional rondavel structure in a homestead, any other house design such as butterfly or flat-roof corner houses can be used for traditional ceremonies: “any house structure can be used as a rondavel; it does not change the culture. It is the same” (P01).
Regarding food preparation, serving and storage, some people used the contemporary rondavel with slight changes for cooking. For example, food is prepared in the family house’s upper part (B section in Fig. 6 ) using a gas or electric stove instead of a hearth at the centre. Others will prepare food and store it in the kitchen of the main house, but people will be served in the contemporary rondavel.
This paper used the concept of habitus to understand whether the changing design and structure of rondavels has influenced its utilisation. Habitus refers to the norms, values, habits, dispositions and behaviours of a particular group, which can then guide how they feel, think, act, and use the space. Habitus can be a product of past experiences and practices learned from parents, family experiences, and society (Hong and Zhao 2015 ). It is created and reproduced by structures and practices of society; it is not fixed and changes over time due to particular circumstances (Bourdieu et al. 2000 ; Navarro 2006 ). The study discussed the amaXhosa people’s habitus on the utilisation of the traditional family house rondavel and how it has been influenced by the introduction of contemporary architectural designs. It is noted that architectural change brought by society does not change cultural norms, values, habits, dispositions and behaviours attached to rondavels but results in finding ways to accommodate and preserve its utilisation in new architectural developments and selectively choosing ideas to be transmitted to the contemporary house design. The cultural norms, values, habits, dispositions, and behaviours attached to rondavels have also been influenced by advancements in health and medical innovation, as well as Covid-19.
The findings revealed the habitus of the amaXhosa people at the Mbhashe Local Municipality. The utilisation of the traditional family house rondavel includes childbirth, placement of the deceased’s coffin, sleeping, seating, food preparation, serving and storage, keeping the spear, hosting ceremonies, communicating with ancestors, and interacting with the living. The amaXhosa habitus is acquired by growing up in the Xhosa society, being taught by parents, and observing how things are done, which has been passed down from generation to generation. The influence of contemporary architecture brought changes in the construction of rondavel.
Home births are no longer practised because of advancements in health and medicine. The placement of the deceased’s coffin in the upper part of the rondavel a day prior to the funeral has been adopted in the use of a contemporary rondavel; however, it is no longer prevalent because of the Covid-19 restrictions. However, on the day of the funeral, the deceased’s coffin is placed in the upper part of the rondavel for a shorter period and a ritual burning incense and asking the ancestors to welcome the deceased is performed because it is a critical cultural practice.
People also do not opt to sleep on the floor unless there is a ceremony. The preparation of food, its serving and storage differs in that there is no hearth in the new contemporary house; so food is prepared in the main house or the upper part of the rondavel. The gendered division of space, hosting ceremonies, communicating and interacting with ancestors has been adopted in contemporary houses too. However, some still prefer to host ceremonies and communicate with the ancestors in traditional rondavels instead.
People have not resisted new architectural designs or changing cultural norms, values, habits, dispositions and behaviours but have found ways to adapt. Certain old dispositions are adaptable to contemporary structures. Also, a study conducted by Moremoholo ( 2021 ) reveals that some indigenous values such as practising ancestral ceremonies can be incorporated or retained in modern house structure. However, some people are not interested in adapting elements to the contemporary rondavel. They would rather have two structures – the current rondavel design and a traditional rondavel to be utilised for uses that cannot be adapted to the contemporary rondavel. The presence of traditional rondavel in modern times is also witnessed even in Nigeria (Onyejegbu et al. 2023 ).
Some cultural norms, values, old habits, dispositions, and behaviours of utilising traditional rondavels were not adapted to the contemporary rondavel because of health and medical innovations such as childbirth and placing the deceased’s coffin in the rondavel. Clearly, some amaXhosa cultural practices are modified but not completely forgotten.
Future studies can focus on profiling architectural designs found in the Mbhashe Local Municipality and investigate their origins and influencing factors. Others could also focus on rondavels utilised by traditional healers to understand how they have been impacted by architectural changes to space utilisation. It will be also interesting to understand why people still opt for traditional rondavels despite the existence of beautiful modern buildings.

Question What duration of oral corticosteroid use is associated with adverse effects among adult patients with atopic dermatitis?
Findings In this nested case-control study including 1 025 270 patients with atopic dermatitis, use of oral corticosteroids for more than 90 days during 1 year was associated with a slightly increased risk of composite adverse outcomes. There was no increased risk with use of oral corticosteroids for more than 30 days.
Meaning This study suggests that for patients with exacerbations of atopic dermatitis, limiting the duration of oral corticosteroid treatment to 90 days or less may limit adverse effects.
Importance The use of oral corticosteroids for prolonged periods may be associated with adverse events (AEs). Nevertheless, the risk of AEs with oral corticosteroids, especially among patients with atopic dermatitis (AD), has not been comprehensively investigated and lacks evidence on duration of treatment.
Objective To assess the association between long-term exposure to oral corticosteroids and AEs among adult patients with AD.
Design, Setting, and Participants This nested case-control study used data from the Health Insurance Review and Assessment Service database of South Korea between January 1, 2012, and October 31, 2021, which included 1 year prior to the cohort entry date of January 1, 2013, for assessing exclusion criteria and baseline characteristics, and 1 year after the study end date of October 31, 2020, to ensure a minimum duration for assessing exposure. Among the population of adults with AD, patients diagnosed with any of 11 AEs were matched with patients who had never received a diagnosis of any of the 11 AEs.
Exposure Long-term use of oral corticosteroids was defined as cumulative supply of more than 30 days or more than 90 days of oral corticosteroid prescription per year.
Main Outcomes and Measures We used multivariable conditional logistic regression analyses to measure the risk of 11 individual outcomes (osteoporosis, fracture, type 2 diabetes, hyperlipidemia, hypertension, myocardial infarction, stroke, heart failure, avascular necrosis, cataract, or glaucoma) as the composite outcome, controlling for potential confounders. We further classified the composite outcome to individual outcomes to evaluate the AE-specific risk.
Results Among 1 025 270 patients with AD between 2013 and 2020, 164 809 cases (mean [SD] age, 39.4 [14.8]; 56.9% women) were matched with 328 303 controls (mean [SD] age, 39.3 [14.7]; 56.9% women) for sex, age, cohort entry date, follow-up duration, and severity of AD, where the balance of most baseline characteristics was achieved. A total of 5533 cases (3.4%) and 10 561 controls (3.2%) were exposed to oral corticosteroids for more than 30 days, while 684 cases (0.4%) and 1153 controls (0.4%) were exposed to oral corticosteroids for more than 90 days. Overall, there was no increased risk of AEs with use of oral corticosteroids for more than 30 days (adjusted odds ratio [AOR], 1.00; 95% CI, 0.97-1.04), whereas the risk was slightly higher with use of oral corticosteroids for more than 90 days (AOR, 1.11; 95% CI, 1.01-1.23). The small elevation in experiencing an AE was observed with each cumulative or consecutive year of ever long-term use.
Conclusions and Relevance This case-control study found a slightly increased risk of AEs associated with use of oral corticosteroids for more than 90 days per year, which warrants future research to fully elucidate the observed findings.
Atopic dermatitis (AD) is a chronic inflammatory disease that causes serious morbidity, such as pruritus, impaired quality of life, and a range of comorbidities. 1 , 2 AD is a lifelong condition that relapses chronically and needs constant care. 3 Although AD is considered primarily a pediatric disease, studies have shown high rates of AD among adults as well. 4 The prevalence of AD among adults ranged from 2.1% to 4.9% across countries, and up to 10% of adults required medication for moderate to severe AD due to inadequate response to topical therapies; the prevalence rates were higher among adult patients than among pediatric patients, of whom 1.5% required medication for moderate to severe AD. 5 - 7
As AD treatment strategies, international guidelines and expert opinions generally recommend that oral corticosteroids should generally be avoided or limited to the short term only as rescue therapy. 8 - 11 Nonetheless, given the benefits of oral corticosteroids, including their effectiveness in allergic diseases, short-term safety, and low cost, many patients with moderate to severe AD are treated with oral corticosteroids for prolonged periods, which may constitute inappropriate or excessive use. 12 , 13 However, oral corticosteroid treatment for prolonged periods could have an association with oral corticosteroid–related complications. 14 Hence, clinical evidence informing patients and practitioners regarding the management of AD exacerbations in routine clinical practice is warranted.
Although previous studies among patients with asthma or rheumatic disease have suggested associations between long-term use of oral corticosteroids and various adverse events (AEs), there are few studies of patients with AD, to our knowledge. 15 - 21 In addition, existing studies about corticosteroid use among patients with AD were conducted to evaluate the safety concerns primarily about topical corticosteroids. 22 - 29 Considering the frequent use of oral corticosteroids among adults with AD and the potential association between long-term use of oral corticosteroids and AEs, some of which are severe, there is a need to investigate the safety of the long-term use of oral corticosteroids among adults with AD. 6 , 30 , 31 Accordingly, we aimed to investigate the association between long-term use of oral corticosteroids and AEs among adult patients with AD in South Korea.
We used the nationwide Health Insurance Review and Assessment Service (HIRA) database of South Korea between January 1, 2012, and October 31, 2021, which included 1 year prior to the cohort entry date of January 1, 2013, for assessing exclusion criteria and baseline characteristics, and 1 year after the study end date of October 31, 2020, to ensure a minimum duration for assessing exposure. It encompasses comprehensive data on health care use for every resident of South Korea, ensuring that patient identifiers are anonymized. The database collects information on socioeconomic and demographic variables, diagnosis ( International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnostic code; setting of diagnosis; date of diagnosis; and others), and medications prescribed (national drug chemical code, days’ supply, dose, date of prescription, route of administration, and others) until the occurrence of emigration or death. A prior validation study examined diagnosis codes documented in the HIRA in comparison with those in electronic medical records and found an overall positive predictive value of 82.3%. 32 This study was approved by the institutional review board of Sungkyunkwan University, which waived the informed consent because only deidentified data were used in this study. This study followed the Strengthening the Reporting of Observational Studies in Epidemiology ( STROBE ) reporting guideline. 33
The study cohort comprised patients who were prescribed oral corticosteroids at least once with an AD diagnosis code from January 1, 2013, to October 31, 2020. The cohort entry date was defined as the first date of the prescription of oral corticosteroids with an AD diagnosis within the study period to include the new users of oral corticosteroids. Eligible case and control groups were identified after excluding the following: (1) patients with a diagnosis of immune-mediated inflammatory diseases during a 1-year window of exclusion assessment before the cohort entry date, to evaluate the risk of AEs from oral corticosteroid use for AD; (2) patients with a diagnosis of any of 11 outcomes of interest during the exclusion assessment window of 1 year before and 1 year after the cohort entry date, to investigate the association of oral corticosteroid use with newly occurred outcomes; and (3) patients who were younger than 18 years of age on the cohort entry date, to include adult patients ( Figure 1 ).
Cases were defined as patients with AD who received a diagnosis of any of our outcomes of interest after the cohort entry date, and the index date was defined as the first date of outcome occurrence. The composite outcome of interest consisted of osteoporosis, fracture, type 2 diabetes, hyperlipidemia, hypertension, myocardial infarction, stroke, heart failure, avascular necrosis (AVN), cataract, and glaucoma. We defined controls as patients with AD who never received a diagnosis of our outcomes of interests after the cohort entry date. We matched each case with up to 2 controls without replacement, using risk-set sampling on the cohort entry date (±30 days), follow-up duration (between the cohort entry date and the index date [±30 days]), age, sex, and severity of AD. Disease severity of AD was classified as moderate to severe on the basis of the current treatment guidelines for AD. 7 Moderate to severe AD was defined as patients who were receiving at least 1 immunosuppressant, alitretinoin, intravenous immunoglobulin, dupilumab, or phototherapy during the 1 year prior to the cohort entry date. The index dates of the control group were aligned with the corresponding index date of their respective matched cases. For individual outcomes, each case was matched with up to 5 or 10 controls, using different numbers from the composite outcome for ensuring statistical power according to the size of cases for each outcome variable, using risk-set sampling as well (eFigure 2 in Supplement 1 ).
We defined the exposure ascertainment window as the period between the cohort entry date and the index date, segmenting the period into yearly intervals to assess exposure year by year to determine whether patients met the definition for long-term use of oral corticosteroids. Owing to the absence of consensus for a definition of long-term oral corticosteroid use among patients with AD, and even for other diseases, we set the classification of long-term oral corticosteroid use as follows: cumulatively more than 30 days as the primary definition for modest long-term use or more than 90 days as a secondary definition for extensive long-term use, both with greater than a 5-mg daily prednisolone-equivalent dose of oral corticosteroids per year, which places patients at risk of systemic adverse effects. 17 To exclude potential use of oral corticosteroids for related conditions other than AD, we restricted exposure to prescriptions of oral corticosteroids to patients with a diagnosis of AD. Ever long-term use was defined as patients with a history of long-term use of oral corticosteroids for at least 1 year, and all remaining patients were defined as no long-term use . Primarily, ever long-term use was defined as a binary variable using 2 thresholds (>30 days and >90 days). In addition, to examine the duration-response association with long-term use of oral corticosteroids, we used the year, which met the definition for the long-term use, as a continuous variable. We assessed the risk of each outcome associated with the number of cumulative years (considering all the intermittent years of long-term use of oral corticosteroids) throughout the exposure ascertainment period. We also evaluated the risk associated with the number of consecutive years (considering only the continuous years of long-term use of oral corticosteroids) within the exposure ascertainment period. Details of the exposure assessment are shown in eFigure 3 in Supplement 1 .
We discerned a sufficient collection of confounding variables that adequately accounted for potential biases in our analysis: demographic characteristics (eg, sex, age, and medical aid recipients), comorbidities (eg, allergic rhinitis, depression, chronic obstructive pulmonary disease, and thyroid disorders), comedications (eg, antidepressants, antibiotics, estrogens, and proton-pump inhibitors), proxies of overall health status (eg, history of hospitalization, number of outpatient visits, and Charlson Comorbidity Index score), and severity of AD. The characteristic assessment window was defined as the 1-year period before the cohort entry date (eFigure 1 in Supplement 1 ; the demographic characteristics [sex, age, insurance] were assessed on the cohort entry date and other characteristics such as comorbidities, comedications, proxies of health status, and severity of AD during the 1 year prior to cohort entry). The details of exclusion criteria, exposures, outcomes, and covariates are presented in eTable 2 in Supplement 1 .
The demographic characteristics of the cases and controls were presented as frequency (proportion) for categorical variables and as mean (SD) or median (IQR) values for continuous variables. The same analysis used to evaluate the demographic characteristics of the cases and controls of patients with AD were repeated for each of the 11 outcomes as secondary outcomes. Differences in baseline covariates between cases and controls were evaluated using the absolute standardized difference, where an absolute standardized difference greater than 0.1 indicates a statistical imbalance existing between 2 groups.
The association between long-term oral corticosteroid use and the risk of the composite and individual outcomes were investigated using multivariable conditional logistic regression analyses to estimate adjusted odds ratios (AORs) with 95% CIs, adjusting for unbalanced comorbidities, comedications, and proxies of health status after the matching. We conducted additional analyses by considering the number of cumulative or consecutive years of long-term use of oral corticosteroids throughout the entire exposure ascertainment window as continuous variables, to investigate the monotonic duration-response association.
The potential heterogeneity of long-term treatment adverse effects in selected subgroups of patients with AD was examined for the composite adverse outcomes according to age (18-39, 40-64, and ≥65 years), sex (male or female), and severity of AD (mild or moderate to severe AD). To evaluate the robustness of the main findings, sensitivity analyses were first conducted by modifying the definition of exposure from a cumulative duration of more than 30 days or more than 90 days per year to more than 60 days per year. Second, we restricted the population to patients who could be followed up for at least 3 years or 5 years from the cohort entry date. All statistical tests were 2 sided. Analyses were conducted using SAS Enterprise Guide, version 7.1 (SAS Institute Inc), provided by HIRA through a virtual access machine.
Of 1 025 270 patients with AD who had at least 1 prescription of oral corticosteroids between 2013 and 2020, we matched 164 809 cases (mean [SD] age, 39.4 [14.8]; 56.9% women and 43.1% men) with 328 303 controls (mean [SD] age, 39.3 [14.7]; 56.9% women and 43.1% men) ( Table 1 ) by 1:2 matching using risk-set sampling. Cases and controls were matched for sex, age, cohort entry date, follow-up duration, and severity of AD; balance was achieved for most covariates between the 2 groups, with an absolute standardized difference of less than 0.1 ( Table 1 ; whole baseline characteristics of cases and controls are presented in eTable 1 in Supplement 1 , individual outcomes in eTables 5-15 in Supplement 1 , and modest long-term [>30 days] vs extensive long-term [>90 days] in eTable 4 in Supplement 1 ). The most common comorbidity was allergic rhinitis (cases, 42.2%; controls, 38.7%), and the most prevalently prescribed concurrent medication was antibiotics (cases, 71.3% and controls, 66.8%). All the imbalanced variables of concurrent medication use and number of outpatient visits were additionally adjusted in the multivariable logistic regression.
Among the 164 809 cases and 328 303 controls, 5533 cases (3.4%) and 10 561 controls (3.2%) were exposed to oral corticosteroids over 30 days, and 684 cases (0.4%) and 1153 controls (0.4%) were exposed to oral corticosteroids over 90 days. Overall, the risk of AEs was not associated with use of oral corticosteroids exceeding 30 days (AOR, 1.00; 95% CI, 0.97-1.04) ( Table 2 ), while use of oral corticosteroids exceeding 90 days was associated with an 11% increased risk of the composite adverse outcome (AOR, 1.11; 95% CI, 1.01-1.23) ( Table 3 ). Each cumulative or consecutive additive year of long-term exposure (>90 days a year) was associated with a slightly increased risk of having an AE (AOR, 1.06; 95% CI, 1.00-1.13 and AOR, 1.06; 95% CI, 1.00-1.13, respectively).
In the analyses of individual outcomes, an increased risk for hypertension (AOR, 1.09; 95% CI, 1.03-1.15), AVN (AOR, 2.56; 95% CI, 1.82-3.62), and cataract (AOR, 3.22; 95% CI, 1.05-9.85) was associated with use of oral corticosteroids for more than 30 days ( Table 2 ). An increased risk for fracture (AOR, 1.22; 95% CI, 1.05-1.42), hyperlipidemia (AOR, 1.16; 95% CI, 1.03-1.30), myocardial infarction (AOR, 2.22; 95% CI, 1.17-4.22), and AVN (AOR, 6.88; 95% CI, 3.53-13.42) was associated with use of oral corticosteroids for more than 90 days ( Table 3 ). In our subgroup analysis, as compared with unexposed patients, the risk of composite AEs associated with long-term use of oral corticosteroids was generally consistent with the main analyses. No differences were observed in the stratified analyses according to the age group, sex, and severity of AD (eFigures 4-6 in Supplement 1 ). Furthermore, the results of composite outcomes demonstrated a high degree of consistency across all sensitivity analyses regarding the point estimates ( Figure 2 ).
We identified 164 809 cases and 328 303 controls of comparable patients with AD. The risk of composite adverse outcomes was not associated with with ever long-term use of oral corticosteroids exceeding 30 days, whereas the risk was slightly associated with ever long-term use exceeding 90 days. Also, the cumulative and consecutive years of ever long-term use throughout entire exposure ascertainment period was associated with a monotonic elevated risk of having an AE, although there was not a large discrepancy between the 2 distinctive analyses of additive years. Furthermore, small increased risks were identified in the examination of individual outcomes of fracture, hyperlipidemia, hypertension, myocardial infarction, AVN, and cataract. Generally consistent findings, with regard to point estimates, were observed across a range of sensitivity analyses.
Considering the overlapping pathogenetic mechanism between AD and asthma, we referred to studies of patients with asthma for comparison. One cohort study using Medicaid data found that the use of medium and high doses of systemic corticosteroids was associated with bone, cardiovascular, metabolic, and ocular AEs. 34 Another cohort study using 2000-2014 MarketScan data showed a similar increased risk of various AEs associated with the use of 1 to 3 oral corticosteroid prescriptions (AOR, 1.04; 95% CI, 1.01-1.06) and the use of 4 or more prescriptions (AOR, 1.29; 95% CI, 1.20-1.37); the cumulative burden also increased as the number of years accumulated. 20 Although previous research evaluated the frequency of oral corticosteroid use based on prescription numbers, our study provided more conclusive and valid clinical evidence by defining long-term use based on exact duration.
For individual outcomes, in line with previous studies, we also identified fracture, hypertension, hyperlipidemia, and myocardial infarction as AEs associated with long-term use of oral corticosteroids, owing to interruption of endocrine function and metabolism. 20 , 35 - 38 We observed risks of AVN and cataract with long-term oral corticosteroid use, although the risks of these 2 conditions were inconclusive in past studies. For the underlying mechanisms for AVN of the femoral head, the use of oral corticosteroids leads to intravascular coagulation that results in a inhibition of blood flow to the bones, which consequently triggers ischemic injury. 39 - 41 Although existing evidence regarding an association of AVN with duration of oral corticosteroid treatment is unclear, AVN could be induced from use of just over 30 days, and cumulative exposure is the important determining factor, as shown in our results. 39 Furthermore, although a complete elucidation remains uncertain, the mechanisms of new-onset cataract associated with modest long-term use of oral corticosteroids may be due to disturbances in osmotic equilibrium, oxidative detriment, and perturbations in lens growth factors. 42 , 43 Another potential hypothesis involves nonenzymatic Schiff base intermediates that form between the corticosteroid’s C-20 ketone group and its nucleophilic groups, undergoing Heyns rearrangement to produce stable amine-substituted adducts seen only in corticosteroid-induced posterior subcapsular cataracts. 44 , 45 No association or subtle increased hazard was observed with osteoporosis, glaucoma, stroke, or heart failure, implying that the dose and duration of corticosteroid treatment may not pose a risk for these conditions among patients with AD.
This study has some strengths. Concerns about conducting this study arose from the lack of consensus regarding the definition of long-term corticosteroid treatment, as different criteria have been used and variations have been observed (eTable 3 in Supplement 1 ). Accordingly, we combined the NICE (National Institute for Health and Care Excellence) guidelines 17 with the opinions of clinicians practicing in clinical settings. Even though evidence for a safe continuous duration of corticosteroid treatment was not available as we developed criteria for the definition of long-term treatment for the dichotomous variable, our criteria are expected to serve as a primary threshold for deciding the duration of treatment. In addition, although the long-term use of oral corticosteroids is not recommended in the guideline for treatment of AD, relatively prolonged use of oral corticosteroids is identified frequently in clinical practice. 12 Thus, this study addresses a significant gap in research by investigating the association between long-term oral corticosteroid use and a comprehensive range of AEs specifically among adults with AD. With its substantial sample size, the study provides robust statistical power to detect associations between oral corticosteroid use and relatively rare outcomes, adding to the existing evidence.
This study also has some limitations. First, disparities arose between the diagnoses recorded and the actual diseases a patient had. 46 In addition, HIRA data do not include clinical data; accordingly, the diagnostic standard criteria for AD, such as the Hanifin-Rajka criteria, 47 , 48 were infeasible. To comply with this issue, we included patients with AD who had at least 1 oral corticosteroid prescription and restricted prescriptions to patients with a diagnosis of AD. Second, due to the inbuilt characteristics of database recording drugs that are prescribed rather than drugs that are taken, the exposure measurement could be uncertain. However, we set the exposed group from the modest long term (>30 days) to the extensive long term (>90 days) and also included the numbers of cumulative or consecutive years of ever long-term use, from which the cumulative burden would be appropriately measured. Third, inhaled corticosteroids, which have some degree of systemic bioavailability, and topical and eye drop formulations of corticosteroids were not accounted for in this study. Fourth, for some of the individual study outcomes, we could not rule out the failure to detect the true effect due to the lack of statistical power; thus, future studies are warranted to corroborate these results. Fifth, due to the nature of the case-control design, it is not possible to completely exclude reverse causality. Sixth, although we considered moderate to severe AD using prescriptions of medication based on the treatment guideline, the influence of AD-related disease severity cannot be eliminated. Seventh, we addressed residual or unmeasured confounders by calculating E-values (eTables 16 and 17 in Supplement 1 ), but unmeasured confounders may be present, and the results should be interpreted with caution.
In this large population-based case-control study, we discovered that oral corticosteroid use of more than 90 days among individuals with AD was associated with a small increased risk of composite adverse outcomes. Future investigations are warranted to confirm this potential risk of AEs associated with long-term use of oral corticosteroids for patients with exacerbations of AD, and health care professionals should thoroughly weigh the benefits associated with oral corticosteroids against the observed small risk of AEs, while continuously monitoring for AEs.

A new ICC Digital Standards Initiative collection of case studies aims to guide businesses and governments seeking to digitalise trade.
Share this:
The ICC Digital Standards Initiative has launched a report, featuring 22 case studies that illustrates how supply chain actors have successfully leveraged digital tools and interoperable global standards to address challenges in their supply chains.
Case studies in the “Key Trade Documents and Data Elements on the Frontlines” report cover both private and public sector actions across four critical areas of digitalisation:
The case studies demonstrate that digitalisation can begin at any point in the supply chain, and be supported by off-the-shelf, proprietary, or a combination of internal and external resources. In addition to localised benefits, digitalisation also brings unexpected advantages, including increased employee engagement, customer loyalty, and innovation opportunities. They also show that a continuous, iterative approach with ongoing learning can maximise benefits over time.
The case studies loosely build on the Key Trade Documents and Data Element (KTDDE) Framework, launched in April 2024, which proposes a unified approach to aligning data across key trade documents, to promote interoperability and data sharing.
Pamela Mar, Managing Director of ICC DSI , said:
“Our goal is to motivate businesses to advance their digitalisation efforts by showcasing diverse paths to transformation. This report provides concrete examples that can widen the circles of action.”
“This report is crucial as it provides actionable insights and real-world examples that can guide organisations through the complexities of digital transformation,” said Stephan Wolf, DSI Industry Advisory Board Chair , and Robert Beideman, DSI Industry Advisory Board Vice Chair.
“It moves us from strategic vision to practical implementation.”
Raphaelle Hemmerlin, Chief Transformation Officer at SUCAFINA SA and a contributor to the report , added:
“Standardised data elements have streamlined our shipping processes, reduced email exchanges and processing times, and allowed us to focus on continuous improvement rather than administrative tasks.”

Title: legacy learning using few-shot font generation models for automatic text design in metaverse content: cases studies in korean and chinese.
Abstract: Generally, the components constituting a metaverse are classified into hardware, software, and content categories. As a content component, text design is known to positively affect user immersion and usability. Unlike English, where designing texts involves only 26 letters, designing texts in Korean and Chinese requires creating 11,172 and over 60,000 individual glyphs, respectively, owing to the nature of the languages. Consequently, applying new text designs to enhance user immersion within the metaverse can be tedious and expensive, particularly for certain languages. Recently, efforts have been devoted toward addressing this issue using generative artificial intelligence (AI). However, challenges remain in creating new text designs for the metaverse owing to inaccurate character structures. This study proposes a new AI learning method known as Legacy Learning, which enables high-quality text design at a lower cost. Legacy Learning involves recombining existing text designs and intentionally introducing variations to produce fonts that are distinct from the originals while maintaining high quality. To demonstrate the effectiveness of the proposed method in generating text designs for the metaverse, we performed evaluations from the following three aspects: 1) Quantitative performance evaluation 2) Qualitative evaluationand 3) User usability evaluation. The quantitative and qualitative performance results indicated that the generated text designs differed from the existing ones by an average of over 30% while still maintaining high visual quality. Additionally, the SUS test performed with metaverse content designers achieved a score of 95.8, indicating high usability.
