How can you evaluate the impact of an intervention?
First, developing a logic model to illustrate the intended impact is helpful. Let's use an increase in knowledge as an example. To evaluate an intervention's impact on the increase in knowledge, a monitoring and evaluation plan will be necessary. Before implementing the intervention, you can administer a pre-test that assesses the information discussed in the intervention to the participants. After the program, you can administer a post-test to the same participants. Statistical tests will reveal the change in knowledge among the participants. An assessment of the attributable-nature of the intervention on the change in knowledge will be necessary.
How do I structure a paragraph?
You should start with a topic sentence that guides the theme of the paragraph. Then, you should follow a P-P-C format. The first "P" represents your point. You should make your argument. The second "P" represents your proof. You should provide the evidence that supports your argument. The "C" represents your comment. You should follow-up your proof with a comment that relates the information to your topic sentence. You can repeat the P-P-C structure multiple times in one paragraph, as long as the points all relate to the topic sentence. You should conclude your paragraph with a concluding sentence.
If I want to study the association between a rare disease and a predictor, how should I collect the data?
A rare outcome or disease is best studied through a case-control study design. Thus, you will need to identify the cases and the controls before identifying the exposures and predictors. You can utilize existing records, such as medical records, to identify the cases and the controls.
