Types of Subjects of Case Studies
There are generally five different types of case studies, and the subjects that they address. Every case study, whether explanatory or exploratory, or intrinsic or instrumental, fits into one of these five groups. These are:
Person - This type of study focuses on one particular individual. This case study would use several types of research to determine an outcome.
The best example of a person case is the "Genie" case study. Again, "Genie" was a 13-year-old girl who was discovered by social services in Los Angeles in 1970. Her father believed her to be mentally retarded, and therefore locked her in a room without any kind of stimulation. She was never nourished or cared for in any way. If she made a noise, she was beaten.
When "Genie" was discovered, child development specialists wanted to learn as much as possible about how her experiences contributed to her physical, emotional and mental health. They also wanted to learn about her language skills. She had no form of language when she was found, she only grunted. The study would determine whether or not she could learn language skills at the age of 13.
Since Genie was placed in a children's hospital, many different clinicians could observe her. In addition, researchers were able to interview the few people who did have contact with Genie and would be able to gather whatever background information was available.
This case study is still one of the most valuable in all of child development. Since it would be impossible to conduct this type of research with a healthy child, the information garnered from Genie's case is invaluable.
Group - This type of study focuses on a group of people. This could be a family, a group of friends, or even co-workers.
An example of this type of case study would be the uncontacted tribes of Indians in the Peruvian and Brazilian rain forest. These tribes have never had any modern contact. Therefore, there is a great interest to study them.
Scientists would be interested in just about every facet of their lives. How do they cook? How do they make clothing? How do they make tools and weapons? Also, doing psychological and emotional research would be interesting. However, because so few of these tribes exist, no one is contacting them for research. For now, all research is done observationally.
Think!
If a researcher wanted to study uncontacted Indian tribes, and could only observe the subjects, what type of observations should be made?
Location - This type of study focuses on a place, and how and why people use the place.
For example, many case studies have been done about Siberia, and the people who live there. Siberia is a cold and barren place in northern Russia, and it is considered the most difficult place to live in the world. Studying the location, and its weather and people can help other people learn how to live with extreme weather and isolation.
Location studies can also be done on locations that are facing some kind of change. For example, a case study could be done on Alaska, and whether the state is seeing the effects of climate change.
Another type of study that could be done in Alaska is how the environment changes as population increases. Geographers and those interested in population growth often do these case studies.
Organization/Company - This type of study focuses on a business or an organization. This could include the people who work for the company, or an event that occurred at the organization.
An excellent example of this type of case study is Enron. Enron was one of the largest energy company's in the United States, when it was discovered that executives at the company were fraudulently reporting the company's accounting numbers.
Once the fraud was uncovered, investigators discovered willful and systematic corruption that caused the collapse of Enron, as well as their financial auditor, Arthur Andersen. The fraud was so severe that the top executives of the company were sentenced to prison.
This type of case study is used by accountants, auditors, financiers, as well as business students, in order to learn how such a large company could get away with committing such a serious case of corporate fraud for as long as they did. It can also be looked at from a psychological standpoint, as it is interesting to learn why the executives took the large risks that they took.
Most company or organization case studies are done for business purposes. In fact, in many business schools, such as Harvard Business School, students learn by the case method, which is the study of case studies. They learn how to solve business problems by studying the cases of businesses that either survived the same problem, or ones that didn't survive the problem.
Event - This type of study focuses on an event, whether cultural or societal, and how it affects those who are affected by it. An example would be the Tylenol cyanide scandal. This event affected Johnson & Johnson, the parent company, as well as the public at large.
The case study would detail the events of the scandal, and more specifically, what management at Johnson & Johnson did to correct the problem. To this day, when a company experiences a large public relations scandal, they look to the Tylenol case study to learn how they managed to survive the scandal.
A very popular topic for case studies was the events of September 11th. There were studies in almost all of the different types of research studies.
Obviously the event itself was a very popular topic. It was important to learn what lead up to the event, and how best to prevent it from happening in the future. These studies are not only important to the U.S. government, but to other governments hoping to prevent terrorism in their countries.
There were also several case studies about the survivors of the terrorist attacks. These studies were invaluable, because it is impossible to recreate the events for research purposes. Studies were done focusing on their physical health, mental health, and emotional health. In fact, studies are still being done as time passes.
