Jan 03,  · Researchers investigated the risk factors associated with the development of pulmonary tuberculosis in Russia. A case-control study was performed in the city of Samara, miles south east of Moscow. Cases were consecutive adults diagnosed as having culture confirmed pulmonary tuberculosis at any of the city’s specialist tuberculosis clinics between 1 January and 31 Cited by: 6. Sep 13,  · FC lists both advantages/disadvantages of the Case Control study as below. I put my questions in bold and would appreciate if anyone can help me out. In general, I think I lack understanding of these studies and if anyone can help me out I would really appreciate it. A case-control study is designed to help determine if an exposure is associated with an outcome (i.e., disease or condition of interest). In theory, the case-control study can be described simply. First, identify the cases (a group known to have the outcome) and the controls (a group known to be Cited by:


Case Control - Study Design


Strengths and Weaknesses of Case Studies. There is no doubt that case studies are a valuable and important form of research for all of the industries and fields that use them.

However, along with all their advantages, they also have some disadvantages. In this article we are going to look at both. Case study method is responsible for intensive study of a unit. It is the investigation and exploration of an event thoroughly and deeply.

You get a very detailed and in-depth study of a person or event. This is especially the case with subjects that cannot be physically or ethically recreated. This is one of the biggest advantages of the Genie case. You cannot lock up a child for 13 years and deprive them of everything.

That would be morally and ethically wrong in every single way. So when the opportunity presented itself, researchers could not look away.

It was a once in a lifetime opportunity to learn about feral children. Genie was a feral child. She was raised in completed isolation, with little human contact. Because of the abuse she withstood, case control study advantages, she was unable to develop cognitively.

From infancy she was strapped to a potty chair, and therefore never acquired the physicality needed for walking, running and jumping. If Genie made a noise, her father beat her. Therefore, she learned to not make a noise. Once she was found, researchers studied her language skills, and attempted to find ways to get her to communicate. They were successful.

While she never gained the ability to speak, she did develop other ways to communicate. However, the public soon lost interest in her case, and with that, the funds to conduct the study, case control study advantages. However, her case was extremely important to child development psychology and linguistic theory.

Because of her, we know that mental stimulation is needed for proper case control study advantages. We also now know that there is a "critical period" for the learning of language. Case studies are one of the best ways to stimulate new research.

A case study can be completed, and if the findings are valuable, case control study advantages, they can lead to new and advanced research in the field.

There has been a great deal of research done that wouldn't have been possible without case studies. An example of this is the sociological study Nickel and Dimed. Nickel and Dimed is a book and study done by Barbara Ehrenreich.

She wanted to study poverty in America, case control study advantages, and did so by living and working as a person living on minimum wage. Through her experiment, she discovered that poverty was almost inescapable. As soon as she saved a little money, she was hit with a crisis.

She might get sick, or her car might break down, all occurrences that can be destructive when a person doesn't have a safety net to fall back on. It didn't matter where she lived or what she did. Working a minimum wage job gave her no chances for advancement or improvement whatsoever.

And she did the experiment as a woman with no children to support. This study opened a lot of eyes to the problem of the working poor in America.

By living and working as the experiment, Ehrenreich was able to show first-hand data regarding the issues surrounding poverty. The book didn't end with any solutions, just suggestions for the reader and points for them to think about. Using this case study information, new studies could be organized to learn better ways to help people who are fighting poverty, or better ways to help the working poor. Oftentimes there are theories that may be questioned with case studies. John-John focused on a set of twin boys, both of whom were circumcised at the age of 6 months.

One of the twin's circumcisions failed, causing irreparable damage to the penis. His parents were concerned about the sexual health of their son, so they contacted Dr. John Money for a solution. Money believed that sexuality came from nurture, not nature, and that the injured baby, Bruce, could be raised as a girl.

His penis was removed and he was sexually reassigned case control study advantages become a girl. Bruce's name was changed to Brenda, case control study advantages, and his parents decided to raise him as a girl. In this case, Dr. Money was dishonest. He believed that gender could be changed, which has since been proven false. Brenda's parents were also dishonest, stating that the surgery was a success, when in fact that wasn't the case.

As Brenda grew up, she always acted masculine and was teased for it at school. She did not socialize as a girl, and did not identify as a female. When Brenda was 13 she learned the truth, and was incredibly relieved.

She changed her name to David, and lived the rest of her life as a male. This case proved that the general theory was wrong, and is still valuable, even though the study author was dishonest.

Case studies have the ability to give insight into phenomena that cannot be learned in any other way. An example of this is the case study about Sidney Bradford. Bradford was blind from the age case control study advantages 10 months old, and regained his sight at the age of 52 from a corneal transplant, case control study advantages. This unique situation allowed researchers to better learn how perception and motion changes when suddenly given sight.

They were able to better understand how colors and dimensions affect the human process. For what it is worth, Bradford continued to live and work with his eyes closed, as he found sight too stimulating. Another famous study was the sociological study of Milgram. Stanley Milgram did a study from to in which he studied the effects of social pressure. The study was set up as an independent laboratory. A random person would walk in, and agree to be a part of the study.

He was told to act as a teacher, and ask questions to another volunteer, who was the learner. The teacher would ask the learner questions, and whenever he answered incorrectly, the teacher was case control study advantages to case control study advantages the learner an electric shock.

Each time the learner was wrong, the shock would be increased by 15 volts. What the teacher didn't know was that the learner was a part of the experiment, and that no shocks were being given. However, the learner did act as if they were being shocked. If the teachers tried to quit, they were strongly pushed to continue. The goal of the experiment was to see whether or not any of the teachers case control study advantages go up to the highest voltage. This study opened eyes when it comes to social pressure.

If someone tells you it is okay to hurt someone, at what point will the person back off and say "this is case control study advantages ok! This study opened up the sociological world of understanding the divide between social pressure and morality.

As demonstrated with the Genie case study, many studies cannot be replicated, and therefore, cannot be corroborated. Because the studies cannot be replicated, it means the data and results are only valid for that one person. Also, Genie was a white, American female. We do not know whether someone with a different gender, race or ethnicity would have a different result.

The effect in which people change their behavior when they are aware they are being observed. When conducting a case study, it is very possible for the author to form a bias. This bias can be for the subject; the form of data collection, or the way the data is interpreted. This is very common, since it is normal for humans to be subjective. It is well known that Sigmund Freud, the father of psychology, was often biased in his case histories and interpretations, case control study advantages.

The researcher can become close to a study participant, or may learn to identify with the subject. When this happens the researcher loses their perspective as an outsider. Any classification is not possible due to studying a small unit. This generalization of results case control study advantages limited, since the study is only focusing on one small group. However, case control study advantages, this isn't always a problem, especially if generalization is not one of the study's goals.

Case studies can be very time consuming. The data collection process can be very intensive and long, and this is something new researchers are not familiar with.

It takes a long period of time case control study advantages develop a case study, and develop a detailed analysis, case control study advantages. Many studies also require the authors to immerse themselves in the case.

For example, in the Genie case, the lead researchers spent an abnormal amount of time with Genie, since so few people knew how to handle her. David Rigler, one of the lead researchers, actually had Genie live with him and his family for years.

The Strengths and Weaknesses of Case Studies Advantages of Case Studies. Intensive Study. Case study method is responsible for intensive study of a unit. It is the investigation and exploration of an event thoroughly and deeply. You get a very detailed and in-depth study of a person or event. This is especially the case with subjects that. Case-control studies. The same problem could also be studied in a case-control study. A case-control study begins with the selection of cases (people with a disease) and controls (people without the disease). The controls should represent people who would have been study cases if they had developed the disease (population at risk). Yet, unless a second comparative group serving as a control is present, these studies are defined as case-series. The next step in strengthening an observation from a case-series is selecting appropriate control groups to conduct a cohort or case-control study, the latter which is discussed in the following section about case-control studies. 9Cited by:
