Answer 3 for PUB 540 Describe the common characteristics and design of a case-control study

by Posted on

Case-Control studies is an analytical and observational study that compares the controls and the group with the disease mainly using questionaires. The main characteristics of a case-control study is that it is a quantitative type of study where the data is collected retrospectively that is from past to future or exposure to effect. The researcher does not follow patients into the future because of its retrospective nature & quicker. Using questionaires do have a few disadvantages such as not being able to see feelings and emotions, analysis is difficult, and the respondants may not be able to respond accurately. Setia (2016) research shows that case-control studies are not useful for rare outcomes but not rare diseases because studying rare diseases is very time consuming.
