What would be the research design and the sampling method for evaluating prevention and education support services for newly diagnosed women with HIV?

The evaluation question is does support services increase quality of life.

Given the already formed research question of your study which analyzes the impact of a given treatment or therapy (prevention and education support services) on patients with a given condition (recently diagnosed HIV), a randomized, controlled study design would best fit your research. In a randomized, controlled study, which is by the way, the standard design for this type of research, you would randomly place the participants in two groups. Both groups would of course receive the standard HIV medical treatments. However, one group would receive prevention and education support services and the other would receive just the standard medical treatment. The impact of the education on the quality of life of the group receiving the services would be compared to the quality of life of the group that did not to determine the education services impact.

A simple random sampling method works best in this situation where there is one group (the HIV positive women) and one needs to create a subgroup. Drawing names or using a computer program to randomly select the subgroup, dividing the group into two, are two common methods of creating a sampling. Once divided, one group receives the treatment, prevention and education support services, while the other does not. Overtime, the impact of the prevention and education support service is qualitatively described and evaluated to determine its impact.

Hello, it sounds like you need some help with statistics. It seems like you have one sample, which is the newly diagnosed women with HIV, and you are trying to evaluate if prevention and education support services increase their quality of life. Now, here are a couple of important questions that you need to answer in order to understand what type of sampling method and research design you need to implement in order conduct your research study. Are you trying to test two different services? Is prevention and education two different variables that you are trying to test? Should there be a control group and experimental group (group of women who receive the services or group of women who do not receive the services)? Are you trying to test the differences between the outcomes or are you trying to test a relationship between quality of life and receiving support services? Depending on how you answer these questions, I can help you take the next step to understanding which sampling methods and tests to conduct in order to test your hypothesis. You will also need to formulate a hypothesis depending on your research question. However, because beginning your research, forming a good research focus is the most important key to fully understanding what research design you will have.
