In a case-control study, there are two groups of people. These studies are mostly used in a range of disciplines.

Now that we have a fair understanding of a cohort study let us move on to the next section.Ī case-control study is a research design used by researchers where the research begins with an outcome in order to comprehend the cause. In such an atmosphere, it is vital that the researcher maintains a good rapport with the cohort. The specialty in cohort studies is that they can be longitudinal studies that go on for months or even years. The researcher then identifies those who have the disease and those who do not and study both groups with the intention of identifying the risk factors. The individuals in the cohort may or may not develop the diseases in question. In a cohort study, a researcher begins to study a particular group (such as women) who share a common characteristic. Let us comprehend this through an example. In medical disciplines, a cohort study allows the researcher to comprehend a potential cause of disease. Simply, cohort study relates the life histories of people. In all these disciplines, a cohort is studied with the intention of gaining a unique experience that the individuals underwent. For example, people born in 1991 belong to a single cohort since they share a specific characteristic with others (year of birth).Ĭohort studies are used in various disciplines ranging from social sciences to medicine. This can be an experience that the individuals shared such as exposure to a traumatic event or even a particular year in which the individuals were born, graduated, etc. What is a Cohort Study?Ī cohort refers to a large group of people who share similar characteristics.

Through this article let us further examine the differences between a cohort study and a case-control study. One key difference between cohort and case-control study is that the cohort study is prospective while the case-control study is retrospective. On the other hand, a case-control study is a research design used by researchers where the research begins with an outcome to comprehend the cause.

A cohort study is a research design where the researcher studies a group of people, also known as a cohort, for a longer period of time. Based on these, the researcher chooses a research design that will be most appropriate for the study. A researcher who is about to conduct a study on a specific field usually has research objectives and questions. Key Difference – Cohort vs Case-Control StudyĬohort and case-control study are two of the designs used in research between which some difference can be identified.
