Why might researchers choose case studies in qualitative research?

Researchers might choose case studies in qualitative research for in-depth analysis of a specific instance or individual.

Case studies are a popular choice in qualitative research because they allow researchers to delve deeply into a particular subject, whether it's an individual, group, event, or organisation. This method provides a rich, detailed understanding of the subject that other research methods may not be able to achieve.

One of the main reasons researchers might choose case studies is their ability to provide a holistic view of the subject. Case studies allow researchers to explore multiple facets of a subject, including its context, which can be crucial in understanding complex phenomena. For example, in psychology, a case study on a patient with a particular mental health condition can provide insights into the patient's background, experiences, and environment, all of which can contribute to the condition.

Case studies also allow for the exploration of new or under-researched areas. Because they do not require a large sample size, case studies can be used to investigate rare or unique cases that may not be possible to study through other research methods. This can lead to the discovery of new insights and the development of new theories.

Furthermore, case studies can be a practical choice for researchers. They are often less costly and time-consuming than large-scale quantitative studies. They also allow for flexibility in data collection methods, which can include interviews, observations, and document analysis. This flexibility can be particularly useful when studying dynamic or evolving subjects.

However, it's important to note that while case studies can provide valuable insights, their findings may not be generalisable to a larger population due to the specific nature of the study. This is a limitation that researchers need to consider when choosing this method.

In conclusion, case studies can be a powerful tool in qualitative research, offering in-depth, holistic insights into a specific subject. They are particularly useful for exploring new areas, studying unique cases, and providing a comprehensive understanding of complex phenomena.
